Installing b43 firmware on Ubuntu 11.10

2012-01-15T21:38:00.001+05:30

On my machine suddenly wireless stopped working and the machine in problem started showing following output for lspci -vnn (output edited)

30:00.0 Network controller: Broadcom Corporation BCM4311 802.11a/b/g (rev 01)
Capabilities: [40] Power Management version 2
Capabilities: [58] MSI: Enable- Count=1/1 Maskable- 64bit-
Capabilities: [d0] Express Legacy Endpoint, MSI 00
Capabilities: [100] Advanced Error Reporting
Capabilities: [13c] Virtual Channel
Kernel driver in use: b43-pci-bridge
Kernel modules: ssb

$ sudo lspci -nn
30:00.0 Network controller [0280]: Broadcom Corporation BCM4311 802.11a/b/g [14e4:4312] (rev 01)
The Solution

I am going to install the correct driver for this wireless card. Then I will remove the “incorrect” driver (bcmwl) which Ubuntu installed by default.

$ sudo apt-get update
$ sudo apt-get install firmware-b43-installer
$ sudo apt-get remove bcmwl-kernel-source
$ sudo reboot

You basically need 2 things
b43-fwcutter
firmware-b43-installer.

another method
a copy of the b43 firmware folder, which just needs to be placed in

/lib/firmware/

Download and extract the folder b43 and place it in /lib/firmware

http://dl.dropbox.com/u/10573557/b43_firmware/b43.zip

If a folder b43 already is there, just delete it.

It's always possible b43 won't work, but it should.
Worth a shot, you can always switch back to 'wl'

Sharing BSNL broadband connection among many users at home

2011-12-16T05:40:00.001+05:30

The scenario is
1) you are a home user
2) you have broad band connection from your ISP (Say BSNL,Tata,Airtel etc etc)
3)you have multiple computers at home

You want to share your internet connection among many users at home.

On one of the computers you need to install a software known as CCProxy and on rest of the machines you need to give IP address of this computer where CC proxy is installed.
The machine where CCproxy is installed will be gateway for rest of the computers and CCproxy needs to be installed only on one computer not on all.

I have done same on Ubuntu machines with squid in case you want to dive in your hands to Linux based proxy servers you can use squid as a proxy.
Apache can also be used as proxy (different from Apache Reverse proxy) but if not configured properly you might be used as an open proxy which is very dangerous.

It is much simpler than developing drivers etc
Hope you enjoyed this non geeky stuff :)

Ubuntu Kernel Development

2011-06-17T00:15:00.005+05:30

I am looking for some motivated souls who want to be in active Kernel Development having some experience with respect to Kernel Development. You can find me on Kernel Newbies mailing list also.

I have extensively read the Device Drivers,Orielly book and practiced it,including the Network Drivers book.Apart from this Essential Linux Device Drivers book by
Sreekrishnan Venkateswaran was also one of my favorites.I had read most of the book and hope that you will be having at least this much understanding for the same.
I do not have the hardware available where I can try various kind of Wireless devices but then co ordinating on internet for the same will be a great idea to work towards the same.
Let me know if you are interested.
I am not an expert for Kernel Development but you will not be disappointed working with me.
I am doing all possible efforts to be a part of mainline Kernel Development Team.

Network device driver for my Ubuntu box

2011-03-15T21:29:00.002+05:30

I have not updated this post from a long time as currently I am busy with some other system kind of experiments,you can read more about me if you check this link http://biturl.net/tapas

These days I am studying network device drivers for wifi devices.
I am using my laptop for such experiments.The PCI id of device on my laptop is 14e4:4315.

So if interested to develop along we can share some thoughts.
Rest on this blog I am sharing a char device driver if you are interested to know more of my device driver codes you can drop me a mail.Or contact via Skype.

MODULE_DESCRIPTION("Test driver");

To test the above driver you will have to create a dummy device on your machine via mknod and statically link this module to the device.
Then you will be able read and write on the device.

Orielly Linux Device Drivers Development 3rd edition has been quite useful for the above code.
If you want to understand the network device section you can read 17th chapter of book and
also Oreilly Linux Network Internals describe this topic in great detail.

apache reverse proxy tutorial Ubuntu 10.04

2011-03-06T19:40:00.011+05:30

Rather than going into any further details and wasting your time to further search things on internet or giving lecture to read Eric Stevens non sense guide How to ask questions smart way which you might have faced while asking in forums.
Here is a small scenario where you would like to configure an Apache Reverse proxy.

You are having a server with a public IP and apache is running on it.Now you want to host your applications on LAN and also want them to be accessible on internet the important part is these applications are still running on the machines on LAN.

let say the websites are :

a)internal1.example.com should map to internal1.example.com
b)internal2.example.com should map to internal2.example.com
c)internal3.example.com should point to internal3 .example.com
d)internal4.example.com should point to internal4 .example.com

Following is network configuration

                           |--------------192.168.1.3 
                           |            (internal3.example.com)
                           |
                           |--------------192.168.1.4
                           |            (internal4.example.com)
  (Public IP )             |
            A--------------|
(reverse proxy server)     |
  (192.168.1.25)           |
example.com                |
                           |--------------192.168.1.1
                           |            (internal1.example.com)
                           |
                           |--------------192.168.1.2
                           |            (internal2.example.com)

I am using Ubuntu to host Apache the vhost definition in case of Debian based systems the definiton of websites is done on

/etc/apache2/sites-enabled/*.conf

where *conf corresponds to

internal1.conf internal2.conf internal3.conf internal4.conf

The vhost definition of each of these sites will be as follows

/etc/apache2/sites-enabled/internal1.example.conf

<virtualhost *:80>

      ServerAdmin webmaster@localhost
      ServerName internal1.example.com
      ProxyRequests off
      <proxy *>
      Order deny,allow
      Allow from all
      </proxy >
      ProxyPass / http://192.168.1.1/
      ProxyPassReverse / http://192.168.1.1/
</VirtualHost >

/etc/apache2/sites-enabled/internal2.example.conf

<virtualhost *:80>

      ServerAdmin webmaster@localhost
      ServerName internal2.example.com
      ProxyRequests off
      <proxy *>
      Order deny,allow
      Allow from all
      </proxy >
      ProxyPass / http://192.168.1.2/
      ProxyPassReverse / http://192.168.1.2/
</VirtualHost >

/etc/apache2/sites-enabled/internal3.example.conf

<virtualhost *:80>

      ServerAdmin webmaster@localhost
      ServerName internal3.example.com
      ProxyRequests off
      <proxy *>
      Order deny,allow
      Allow from all
      </proxy >
      ProxyPass / http://192.168.1.3/
      ProxyPassReverse / http://192.168.1.3/
</VirtualHost >

/etc/apache2/sites-enabled/internal4.example.conf

<virtualhost *:80>

      ServerAdmin webmaster@localhost
      ServerName internal4.example.com
      ProxyRequests off
      <proxy *>
      Order deny,allow
      Allow from all
      </proxy >
      ProxyPass / http://192.168.1.4/
      ProxyPassReverse / http://192.168.1.4/
</VirtualHost >

Note in all of the above vhost definitions I have dropped the options of Log files.
So if you apply to a production server add them in each of the vhost file.
Above is just to give you a clear cut example as how it can be working.
I run a very complex Apache setup so above is just a small example to help you.
Rest of the details can vary depending upon your configurations.

how to save bandwidth in git pull when you do a make world on Xen source

2011-03-01T15:19:00.003+05:30

Those who have compiled xen from source must have faced this annoying situation.
When you did a make world then you see some output like this

install -m0644 -p /usr/src/xen-4.0.1/xen/xen-syms //boot/xen-syms-4.0.1
make[2]: Leaving directory `/usr/src/xen-4.0.1/xen'
make[1]: Leaving directory `/usr/src/xen-4.0.1/xen'
for i in  linux-2.6-pvops  ; do make $i-install || exit 1; done
make[1]: Entering directory `/usr/src/xen-4.0.1'
make -f buildconfigs/mk.linux-2.6-pvops build
make[2]: Entering directory `/usr/src/xen-4.0.1'
set -ex; \
        if ! [ -d linux-2.6-pvops.git ]; then \
                rm -rf linux-2.6-pvops.git linux-2.6-pvops.git.tmp; \
                mkdir linux-2.6-pvops.git.tmp; rmdir linux-2.6-pvops.git.tmp; \
                git clone -o xen -n git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git linux-2.6-pvops.git.tmp; \
                (cd linux-2.6-pvops.git.tmp; git checkout -b xen/stable-2.6.32.x xen/xen/stable-2.6.32.x ); \
                mv linux-2.6-pvops.git.tmp linux-2.6-pvops.git; \
        fi
+ [ -d linux-2.6-pvops.git ]
+ rm -rf linux-2.6-pvops.git linux-2.6-pvops.git.tmp
+ mkdir linux-2.6-pvops.git.tmp
+ rmdir linux-2.6-pvops.git.tmp
+ git clone -o xen -n git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git linux-2.6-pvops.git.tmp
Initialized empty Git repository in /usr/src/xen-4.0.1/linux-2.6-pvops.git.tmp/.git/
remote: Counting objects: 1941611, done.
remote: Compressing objects: 100% (319164/319164), done.

The above really takes long time because it is basically cloning the git repository from jeremy's tree to your local machine and you have to wait until the pull completes.
The size is approximately 875 Mb so you will have to wait till that much time.
After digging this problem for some time I finally found a remedy for the same.

You need to fix the Makefile for the same.

When you untar xen-4.0.1.tar then you see

/usr/src/xen-4.0.1

(location /usr/src can change depending upon where you untarred it at your laptop I prefer /usr/src for all source builds)

Now before you begin any sort of compilation etc in your home directory
pull the git tree as above mentioned (since we will remove the lines from Makefile itself)

so have at some safe location

cd $HOME
git clone -o xen -n git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git linux-2.6-pvops.git.tmp;

At this point you should be able to see $HOME/linux-2.6-pvops.git.tmp we will use this again and again.

Now /usr/src/xen-4.0.1/buildconfigs directory open file
src.git-clone and add a hash # at the beginning of following lines

               rm -rf $(LINUX_SRCDIR) $(LINUX_SRCDIR).tmp; \
               mkdir $(LINUX_SRCDIR).tmp; rmdir $(LINUX_SRCDIR).tmp; \
               $(GIT) clone -o $(XEN_GIT_ORIGIN) -n $(XEN_LINUX_GIT_URL) $(LINUX_SRCDIR).tmp; \
               (cd $(LINUX_SRCDIR).tmp; git checkout -b $(XEN_LINUX_GIT_LOCALBRANCH) $(XEN_LINUX_GITREV) ); \
               mv $(LINUX_SRCDIR).tmp $(LINUX_SRCDIR); \

so that they look as

#               rm -rf $(LINUX_SRCDIR) $(LINUX_SRCDIR).tmp; \
#               mkdir $(LINUX_SRCDIR).tmp; rmdir $(LINUX_SRCDIR).tmp; \
#               $(GIT) clone -o $(XEN_GIT_ORIGIN) -n $(XEN_LINUX_GIT_URL) $(LINUX_SRCDIR).tmp; \
#               (cd $(LINUX_SRCDIR).tmp; git checkout -b $(XEN_LINUX_GIT_LOCALBRANCH) $(XEN_LINUX_GITREV) ); \
#               mv $(LINUX_SRCDIR).tmp $(LINUX_SRCDIR); \

The above lines in src.git-clone are responsible for this time consuming pull.
Now when you need to compile again and again xen-tools you can simply extract
the xen-4.0.1.tar.gz
and
copy the $HOME/linux-2.6-pvops.git.tmp to /usr/src/xen-4.0.1/

now you can begin the compile process again.

make install xen-tools
and it should work fine.

Now here I would like to add some more points that I had also commented out all lines that begin with rm in file

/xen-4.0.1/buildconfigs/mk.linux-2.6-common

since to uninstall the tools I had used
make uninstall and make clean command which is available as clear from the Makefile.
But then I again copied the

$HOME/linux-2.6-pvops.git.tmp to /usr/src/xen-4.0.1 and then again

make xen
make tools
make stubdom
make install xen
make install xen-tools

So your point is only the src.git-clone file.

and got
http://lists.xensource.com/archives/html/xen-users/2010-12/msg00230.html

the solution they seem to mention is open a file

vi /usr/src/xen-4.0.1/buildconfigs/src.git-clone

and

# Replace Line
# (cd $(LINUX_SRCDIR).tmp; git checkout -b $(XEN_LINUX_GIT_LOCALBRANCH) $(XEN_LINUX_GITREV) ); \
# with:
# (cd $(LINUX_SRCDIR).tmp; git checkout -b local/$(XEN_LINUX_GIT_LOCALBRANCH) --track $(XEN_LINUX_GITREV) ); \
make world
sudo make install

Also seems that compiling as root has issues with Xen so don't do it as root.

Seems Xen has always some circus to do when yo do a make world that is why it is not shipped as binary with most of the distributions.

Next I proceeded with above solution then I got stuck up here in following questions

log4j:ERROR Could not parse url [file:/usr/share/tomcat6/lib/log4j.xml]

2011-02-26T08:21:00.000+05:30

I encountered this problem while working with an LMS known as OLAT

when I do a restart of tomcat server as /etc/init.d/tomcat6 restart

then in catalina.out I see following

log4j:ERROR Could not parse url [file:/usr/share/tomcat6/lib/log4j.xml].

As a remedy to this problem the only work around I observed working is
I delete /usr/share/tomcat6/lib/log4j.xml
and create it again as mentioned here
https://lists.uzh.ch/lists.olat.org/sympa/arc/olat-users/2010-11/msg00054.html
and then restart tomcat6 then the above error goes and I am able to
get olat back.

Getting IP in X-Forwarded-For field logged in

2011-02-22T06:58:00.012+05:30

If you run a cluster of servers in a reverse proxy situation then you must have encountered this where you want to log the actual IP of request coming in forwarded via the Reverse Proxy server.This IP is in X-Forwarded-For field of header.

You can define some custom log with your apache vhost configuration

LogFormat "%{X-Forwarded-For}i %a %D %>s %B" resp
CustomLog /var/log/apache2/resp.log resp

To be able to record or observe your desired format of logs.

On one of my machines I had done this mistake apache2.conf where I have commented out the wrong line

LogFormat " %{X-Forwarded-For}i %l %u %t \"%r\" %>s %O \"%{Referer}i\" \"%{User-Agent}i\"" combined
#LogFormat "%h %l %u %t \"%r\" %>s %O \"%{Referer}i\" \"%{User-Agent}i\"" combined
LogFormat "%h %l %u %t \"%r\" %>s %O" common
LogFormat "%{Referer}i -> %U" referer
LogFormat "%{User-agent}i" agent

one line with keyword combined at the end is hashed.That was a mistake having a CustoLog Format with keyword combined at 2 lines had created problem.I am not sure why it had not worked the time when I was writing.Since I am already running 12-13 websites on this one which is a part of a larger cluster so mentioning it (keyword combined ) in 2 different lines
was causing trouble in other vhosts.Only one place is sufficient to log in apache2.conf.
How ever you should define some thing in your vhost files also.
You can do some thing similar in the vhost file

<virtualhost *:80>
        ServerAdmin webmaster@localhost

        ServerName 
        ProxyRequests off
       <Proxy * >
       Order deny,allow
        Allow from all
       </Proxy>

        DocumentRoot /var/www
        <directory />
                Options FollowSymLinks
                AllowOverride None
        </Directory>
        <directory /var/www/>
                Options Indexes FollowSymLinks MultiViews
                AllowOverride All
                Order allow,deny
                allow from all
        </Directory>
  ErrorLog /var/log/apache2/error.log

        # Possible values include: debug, info, notice, warn, error, crit,
        # alert, emerg.
        LogLevel warn


        CustomLog /var/log/apache2/access.log combined
        CustomLog /var/log/apache2/resp.log resp

</VirtualHost>

Now note the combined keyword here at the end.The log format in apache2.conf corresponding to keyword combined and resp gets mapped here.

<virtualhost *:80>
        ServerAdmin webmaster@localhost

        ServerName 
        ProxyRequests off
       <Proxy * >
       Order deny,allow
        Allow from all
       </Proxy>

        DocumentRoot /var/www
        <directory />
                Options FollowSymLinks
                AllowOverride None
        </Directory>
        <directory /var/www/>
                Options Indexes FollowSymLinks MultiViews
                AllowOverride All
                Order allow,deny
                allow from all
        </Directory>
  ErrorLog /var/log/apache2/error.log

        # Possible values include: debug, info, notice, warn, error, crit,
        # alert, emerg.
        LogLevel warn


        CustomLog /var/log/apache2/access.log combined
        CustomLog /var/log/apache2/resp.log resp

        CustomLog /var/log/apache2/access.log myformat
        LogFormat "%{X-Forwarded-For}i  %D %t %T %v %O %b %A %B" myformat
</VirtualHost>

Now note the last 2 lines this way you can have your formats if you do not want to mess with apache2.conf.

Some useful information which you can capture in logs is
%{X-Forwarded-For}i IP of user coming behind a proxy
%v server name for which request is coming if you have multiple websites this helps
%T time taken to serve requests in seconds and if you want in microseconds then use
%D
%{User-agent}i user-agent refers to client browser
%t the time at which server recieved request (English Date Format)

Installing Xen 4.0 on Ubuntu 9.04

2011-02-16T14:21:00.020+05:30

Your boss pointed gun at your head and gave you two hours to make things work (I have had the privilege of working with one such person)
and to save your life you are searching various places on internet
You posted on a lot of forums and rather than getting any solution to your original problem what you were said to read is Eric Stevens non sensical guide
http://www.catb.org/~esr/faqs/smart-questions.html
and because of people like Eric Stevens using Linux or what ever becomes a real pain when most of the time on a forum the people who will give you some rant actually do not understand the issue.

Coming to real point

You downloaded Xen 4.0 on Ubuntu and now realized
the instructions here
https://help.ubuntu.com/community/Xen
are shit.
Then you are at the correct place.
What they don't tell you is to install dpkg-dev bridge-utils libncurses5-dev debhelper fakeroot
build-dep

typed
make world KERNELS="linux-2.6-xen0 linux-2.6-xenU"
as normal user you will get some thing similar.

Solution of above problem

install the mercurial tool hg that is why you got above error.
sudo apt-get install mercurial

After this you some how started the process again

Now for your good health when you are doing circus with source codes it is always good to have them in /usr/src

make xen
make tools
make stubdom
make install-xen
make install-tools
make install-stubdom

and then compile dom0 kernel following
http://wiki.xensource.com/xenwiki/XenParavirtOps.
or perhaps a "make world" (without anything after that) might do
all the steps, but I prefer doing it one by one

mkdir linux-2.6-pvops.git.tmp
+ rmdir linux-2.6-pvops.git.tmp
+ git clone -o xen -n git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git linux-2.6-pvops.git.tmp
/bin/sh: git: not found

make: *** [world] Error 2

Solution for your stupid boss

aptitude install git-core

Then after this a circus which lasted for about 4 hours or more I got following

elif make -C linux-2.6-pvops.git ARCH=$(sh buildconfigs/select-linux-arch linux-2.6-pvops.git) defconfig O=$(/bin/pwd)/build-linux-2.6-pvops_x86_32 ; then \

 else \

 fi

My internet connection keeps disconnection so my make world stops

how to stop default website from getting served in Apache2,Why is there a 000-default file

2011-02-16T08:02:00.000+05:30

I run 14 + websites which are divided into a cluster sort of situation i.e. a group of websites on one node another group on another node like this.The requirement of my work keeps increasing in such a situation I found one important thing after discussing on Apache users group and Ubuntu forum.This is applicable for people using Ubuntu or Debian sort of system.
When you use name based virtual hosting to host different websites some times you must have encountered a situation where what ever you are typing in URL is going to some virtual host which is always serving your request even though the original request was not meant for this URL to be served.

What happens is in Ubuntu/Debian based system you define your vhosts in /etc/apache2/sites-available directory.

Some thing such as

abchost1.conf
abchost2.conf
abchost3.conf
abchost4.conf

When apache reads these vhost configurations it does so in a alphabetical order.
That is the reason when you install Apache on Ubuntu you see a file with name
000-default always so as to give priority to this file in case of any request going to some
wrong path.This vhost is one which will reply.
In case 000-default is missing then what ever alphabetically comes next.
That is half the reason your URLs mismatch and when you expected some thing, some thing else came.
As a proof read this link
http://httpd.apache.org/docs/2.2/mod/core.html#include
which says following line
"wildcard characters can be used to include several files at once, in alphabetical order. "

and if you ever noticed in /etc/apache2/apache2.conf
you will notice the last line
Include /etc/apache2/sites-enabled/

which includes all the vhosts definitions in sites-enabled directory and as per above link of Include directive of apache doc it reads those vhosts in alphabetical order.

What this means is suppose you have 3 Name Based Virtual Hosts on same machine

lets say
abc1.com
abc2.com
abc3.com

with configurations like these
/etc/apache2/sites-enabled/abc1.conf

<VirtualHost *:80>
        ServerAdmin webmaster@abc1.com

         ServerName abc1.com
        DocumentRoot /var/www
        <Directory />
                Options FollowSymLinks
                AllowOverride None
        </Directory>
        <Directory /var/www/>
                Options Indexes FollowSymLinks MultiViews
                AllowOverride All
                Order allow,deny
                allow from all
        </Directory>
</VirtualHost>

Second /etc/apache2/sites-enabled/abc2.conf

<VirtualHost *:80>
        ServerAdmin webmaster@abc1.com

         ServerName abc2.com
        DocumentRoot /var/www
        <Directory />
                Options FollowSymLinks
                AllowOverride None
        </Directory>
        <Directory /var/www/>
                Options Indexes FollowSymLinks MultiViews
                AllowOverride All
                Order allow,deny
                allow from all
        </Directory>
</VirtualHost>

Third /etc/apache2/sites-enabled/abc3.conf

<VirtualHost *:80>
        ServerAdmin webmaster@abc1.com

         ServerName abc3.com
        DocumentRoot /var/www
        <Directory />
                Options FollowSymLinks
                AllowOverride None
        </Directory>
        <Directory /var/www/>
                Options Indexes FollowSymLinks MultiViews
                AllowOverride All
                Order allow,deny
                allow from all
        </Directory>
</VirtualHost>

and now a requests goes to this server as
http://abcdef.com

Then apache will try to match the ServerName abc1.com it will not find abcdef there
then
ServerName abc2.com here also it will not find abcdef there
then
ServerName abc3.com here also
it will not find abcdef there
then
the request will be served by the alphabetically 1st vhost i.e. abc1.conf which has ServerName abc1.com.Note when I say alphabetically I mean the file name of vhost is important.

To get rid of such situation define one more Vhost 000-abc.conf

where I added 000 because it alphabetically will get first priorirty and there we can define what Apache needs to do in such situations where request does not have a valid HTTP_HOST
or in case of other errors also this is a very standard practice.

Project hosting with Google Code

2010-12-14T13:15:00.012+05:30

Ok if you reached this page I can imagine your frustration.You wasted reading the official guides for using mercurial and google code and finally realized that all that was a waste of time.If that is the feeling then you reached the right page.

Let us go straight to work without wasting your time.(I had wasted a lot of time when I started)
This is your first time to using any sort of version control system and you do not want to read ugly man pages (in fact most of the man pages were pieces of crap written in 1960's or 70s).

First create an account with Google Code (which you might have done that is why you are reading this guide)

Then you run following command in an empty subdirectory

hg clone https://yourproject.googlecode.com/hg/ yourproject

you will see a directory yourproject now.

Inside this you will see a .hg directory which has hgrc file.
So

vi testproject/.hg/hgrc

is the file you might have been wondering on internet as how to use.

Now copy your code in what ever location from your laptop to this directory
i.e.

bash$ cp -rv /whereever/your/code/on/laptop/   testproject/

now

cd testproject

then

hg add ./*

and then hg push this the command that you should do so that the code on your laptop can be seen on internet on Google code.

Right upto here if every thing was Ok then

hg commit -A

after some conversation with this command you should be fine.

Here is a good link
http://www.trisis.co.uk/blog/?p=580
which told me when you run
hg push then the password that you will enter is not the same as the password you use on gmail.
excerpts from the above link

"This will prompt you for a user name and password, the password IS NOT YOUR DEFAULT PASSWORD. Go to your accounts hosting page to find it."
the link to find your password is

https://code.google.com/hosting/settings

In case you enter user gmail username password you will get following error

abort: HTTP Error 403: Forbidden

Now things should work well for you.

Let me know via your comments if you know any more information.
Most of the guides I read were highly time consuming and did not talked to the point things.

Mechanism of function calls what does a processor do when function call is made

2010-08-28T13:32:00.011+05:30

A question on Kernel Newbies mailing list related to function calls in timer.c
prompted me to right this here.
The original thread can be seen here
http://www.spinics.net/lists/newbies/msg40013.html

To make a function call CPU has to save registers and pass on ret
instructions when ever the function call ends
if we have a small fucntion which is used in a file and a function
call via CPU then over head of saving flag registers ,saving stack and
making the called function return to the location where the call was
made is so much that it is preferred to replace that call via the
actual function itself hence if some one has such a function which has
is of very less number of lines and has been called once or twice then
it is good to declare it inline.

The overhead that CPU has to undergo if the function is not inline is saving the current context ,flag,stack,heap ,(what ever is)the state of code in execution and then load the called function from a specific memory location.
Doing this for small subroutines is resource consuming.So it is a good practise among kernel developers do declare functions inline when it is used once or twice and saves the CPU the over head involved in saving the stack,program counter flag registers and other registers which are being related to the program in execution.

By using the word in laymans language I will say that part of code (function ) is actually written where ever the function call is made.

For example following program

example1.c

#include<stdio.h>
inline function ingen (X1,X2)
{
does some thing some thing
return c;
}

function b( )
{
step = function ingen ();
}
main()
{
b ();
}

If you were to execute above code

call to function ingen () via function b() would replace the function ingen() by the code inside function ingen().

If you would not have declared function ingen as inline function then the CPU would jumped to some memory location where function ingen() is actually residing and then executed.

In this case CPU just have to insert that code what ever function ingen() does when ever a call to function ingen() is made via function b().

Or which ever function in the code calls function ingen().

If the keyword static is added so that if the same function has been used at any other place then it should not affect the other files.Meaning the word static before a function makes its scope limited to that file only.

If you have another program example2.c and compile

cc example1.c example2.c
then functions in exampl1.c would be available to example2.c and vice versa but use of word static restricts the function in their respective files.
i.e. if example1.c has a static function then it will not be available to example2.c

What static does is to create a label for a certain global memory chunk and give that a value at compile time, plus not making it available to the linker.

Look at these examples

static int mystatic = 6;

int main(void)
{
return 0;
}

Generated ASM is as follows:

Code:

.file "static2.c"
.data
.align 4
.type mystatic, @object
.size mystatic, 4
mystatic:
.long 6
.text
.globl main
.type main, @function
main:
pushl %ebp
movl %esp, %ebp
movl $0, %eax
popl %ebp
ret
.size main, .-main
.ident "GCC: (Debian 4.4.4-8) 4.4.5 20100728 (prerelease)"
.section .note.GNU-stack,"",@progbits

Compare that with declaring the global variable as non-static:

Code:

int mynonstatic = 6;

int main(void)
{
return 0;
}

Code:

.file "nonstatic2.c"
.globl mynonstatic
.data
.align 4
.type mynonstatic, @object
.size mynonstatic, 4
mynonstatic:
.long 6
.text
.globl main
.type main, @function
main:
pushl %ebp
movl %esp, %ebp
movl $0, %eax
popl %ebp
ret
.size main, .-main
.ident "GCC: (Debian 4.4.4-8) 4.4.5 20100728 (prerelease)"
.section .note.GNU-stack,"",@progbits

The only difference is that in the non-static case, there's the .globl mynonstatic that makes that symbol available to the linker.
Now, careful observation will make you notice that both global variables are declared as labels, exactly the same way as main is. ASM doesn't really distinguish between functions and variables (the @function and @object thing is just an optimization gcc does): all there is memory addresses that you conveniently can refer to with a label. So, when you declare a function static, what will happen is exactly the same: the function is given a value (its code) and make it unavailable to the linker... exactly what was done to the variable.

Here you have the C and ASM for a static function:

Code:

.file "stat_func.c"
.text
.type something, @function
something:
pushl %ebp
movl %esp, %ebp
movl $0, %eax
popl %ebp
ret
.size something, .-something
.ident "GCC: (Debian 4.4.4-8) 4.4.5 20100728 (prerelease)"
.section .note.GNU-stack,"",@progbits

Again, the value for something is its code, it's a global value but not available to the linker because there's no .globl something.

What about local static variables? Actually, the idea of local variables is lost when compiling C to ASM. What you have is a global stack that each function is in charge to clean up when returning... therefore making its local values no longer available outside the function... but place a jmp and the value will be available. What happens with static variables is that the static again sets up a value at compile time and makes the symbol unavailable for the linker... as you'll see here:

Code:

int main(void)
{
static int mystatic = 6;

return 0;
}

Code:

.file "static.c"
.text
.globl main
.type main, @function
main:
pushl %ebp
movl %esp, %ebp
movl $0, %eax
popl %ebp
ret
.size main, .-main
.data
.align 4
.type mystatic.1248, @object
.size mystatic.1248, 4
mystatic.1248:
.long 6
.ident "GCC: (Debian 4.4.4-8) 4.4.5 20100728 (prerelease)"
.section .note.GNU-stack,"",@progbits

The only difference here is that the .data section has been placed *after* the main "rets" (a kind of return you have in ASM...)... ASM indentation is awful here, but actually main ends at the ret, not at the mystatic.1248 label. Ok, I'm not sure why the name is "mangled" but it's clear that the variable is declared as global even when we declared it as local in C. What will happen is that the C compiler will restrict the usage of that symbol to the main function, but you clearly see that it's just a way to create the illusion of locality... It's actually a global and that's why its value is persistent across the program's execution.

So, in summary, it seems that the real effective meaning (I don't care what the standard says) of static is "Make a global memory address not be available to the linker"... therefore we can explain why is it used both for functions and variables.

Of course, tutorials are doing fine to explain this the way they do... As you see, you have to step down to ASM in order to make some sense of this. Also, this is another great reason of why C is such a pain to use: in the end you still have to understand the basics of ASM... while to use bash, Perl, Python you don't need to know C (or the language the implementation is written in).

Since Linux kernel is made up of C and to make sure functions with similar names(if any) exist then they are not conflicting it is a good practice to declare a function as static.

Declaring it inline reduces the overhead that CPU would have to do in actually calling a function.

To have more digging about this you need to understand mechanism of function call as what does
processor do when a function call is made.

Clearly if you have a large code to execute the
instruction is in memory and it has to come to cache so if you have
large code and you declare that as inline it has disadvantage that
cache miss will more.

What I wanted to
say is if you have a function is used at 10 places and you declare it
inline 10 times then there would be cache miss more (because that inline part of code would not be in cache) and this will
have disadvantage.

Voyage to Linux Kernel Day 12 program errors

2010-08-20T08:30:00.002+05:30

I am trying the program from Linux For You magazine Day 12 of Voyage to Linux Kernel
June 2009 edition.
From Aasis Vinayaks column following is the program on my Ubuntu laptop

#include
#include
#include
extern void *sys_table[];
asmlinkage int(*main_sys_exit)(int);
asmlinkage int alt_exit_function(int err_code)
{
printk("Sys_exit called with err_code=%d\n",err_code);
return main_sys_exit(err_code);
}

int init_module()

sys_table[__NR_exit]=alt_exit_function;
}
void cleanup_module()
{

}

Has given a lot of errors discussed on Kernel Newbies mailing list.
Here
http://www.spinics.net/lists/newbies/msg39896.html
Seems to have been the longest discussion in the history of Linux Kernel Newbies mailing list.
Please do suggest if you feel any correction is needed in the program.

hello kernel

2010-08-16T20:33:00.000+05:30

Here is the program
#include
#include
MODULE_LICENSE("Dual BSD/GPL");
static int hello_init(void)
{
printk(KERN_ALERT "Hello,world tapas\n");
return 0;
}
static void hello_exit(void)
{
printk(KERN_ALERT "Good Bye,cruel world\n");
}
module_init(hello_init);
module_exit(hello_exit);

and the corresponding make file for this is

all:
make -C /lib/modules/$(uname -r)/build/M=$(PWD) modules
clean:
make -C /lib/modules/$(uname -r)/build/M=$(PWD) clean
clean-files:=Module.symvers

and to compile
make -C /lib/modules/`uname -r`/build/ M=`pwd`

thats it.

I got following output

Excluding the unwanted directories from the search on Linux

2010-08-07T12:22:00.000+05:30

If you want to search and exclude a particluar directory in your search then you can do it in following three ways

Method 1
Suppose I want to search a file lighttpd but exclude that search from my home directory
then
find / -name lighttpd | grep -v "^/home/" | xargs ls -l

Method 2
a for-loop and the command "dirname" will help here...
(if [ ! `dirname $i` = "/home" ]; then ...)

Method 3
Excluding the unwanted directories from the search
find / -wholename /home -prune -o -name lighttpd -exec echo rm {} \;

Explanation of method 3

The action -prune just tells find to not descend into directories. Let's look at every single
step of method 3 above

a. Look for a directory whose whole name is /home
Code:

$ find / -wholename /home
/home

The name is relative to the specified search path, in this case / (root). This tell us that there is (obviously) only one item whose name is /home.

b. Add -prune
Code:

$ find / -wholename /home -prune
/home

Nothing different here, because the action -prune alone is evaluated as true and the result is to print the directory name. Actually the rule here is: if the expression contains no actions other than -prune, -print is performed on all files for which the expression is true.

c. Add an alternative (logical OR)
Code:

$ find / -wholename /home -prune -o -name lighttpd -print
/etc/init.d/lighttpd
/etc/lighttpd
/opt/lighttpd-1.4.x/src/lighttpd

Note that the expression here contains at least one action other than -prune (-print), so that the rule cited above does not apply. For this reason, when find encounters /home the left-hand-side of the expression is true and the output is null now. Instead for all the other directories, the left-hand-side of the expression is false and the right-hand-side is evaluated (in this case every file whose name is lighttpd is printed out).

Note that if you omit -print (without adding any other action) the rule above is applied and -prune still has the effect to not descend into the directory, but the directory name is printed out:

Code:

$ find / -wholename /home -prune -o -name lighttpd
/etc/init.d/lighttpd
/etc/lighttpd
/home
/opt/lighttpd-1.4.x/src/lighttpd

In my previous example the action -exec prevents this behaviour.

Finally you can omit multiple directories from the search by expanding the left-hand-side of the expression with other alternatives (embedded in escaped parentheses). For example:
Code:

$ find / $ -wholename /home -o -wholename /etc $ -prune -o -name lighttpd -print
/opt/lighttpd-1.4.x/src/lighttpd

d. If you want to know what {} do read man find and search for -exec section

-exec command ;
Execute command; true if 0 status is returned. All following arguments to find are taken to be arguments to the command until an argument consisting of
`;' is encountered. The string `{}' is replaced by the current file name being processed everywhere it occurs in the arguments to the command, not just
in arguments where it is alone, as in some versions of find. Both of these constructions might need to be escaped (with a `\') or quoted to protect them
from expansion by the shell. See the EXAMPLES section for examples of the use of the -exec option. The specified command is run once for each matched
file. The command is executed in the starting directory. There are unavoidable security problems surrounding use of the -exec action; you should use
the -execdir option instead.

Installing Red5 on Ubuntu 9.04 32 bit

2010-08-01T21:04:00.001+05:30

Installing Red5 on Ubuntu 9.04

Assuming you do not know what ant,svn,Red5 are and you have just installed Ubuntu 9.04 on your desktop.

Now you are wondering where in the world you should be doing all these things.
If you are trying this blog and some thing does not works for you drop me a mail so that I can understand what you missed and try to help you.

Before we begin
If you are a complete newcomer then read

you need to know what is
1)ant
2)svn
3) how to set class paths in Linux

Let us begin with creating an environment to be able to install Red5.
Red5 is based on Java.
So you need to have Java installed in your computer.
If you do not have

then Start here otherwise you can jump to Step 14

Install JAVA for Red5

Step1) Check
/etc/apt/sources.list
and enable or add following lines if you do not have already note the partner word at the end

deb http://archive.canonical.com/ubuntu jaunty partner
deb-src http://archive.canonical.com/ubuntu jaunty partner

Step2) Do an apt-get update
and type
apt-get install sun-jdk6-java

it should work
if you have any problems
I will strongly recommend to check following links (I faced problems which got solution on these links)
http://zebardast.ir/en/installing-sun-jdk-5-on-ubuntu-9-10-and-10-04/
http://www.linuxquestions.org/questions/linux-software-2/java1-5-installation-error-ubuntu-10-04-server-edition-uname-2-6-32-23-server-817569/

Please do not install jre for Red5 as Red5 needs jdk and not jre as you will read below in this post.

Step 3) Now go to /etc/profile.d/ and create a file named jdk.sh

export JAVA_HOME=/usr/lib/jvm/java-6-sun
export PATH=$JAVA_HOME/bin:$PATH

Install ant

I will strongly recommend to install latest ant binary from apache website do not use old versions I had some errrors which actually were resolved when I used the latest ones
Step 4) Download http://ant.apache.org/bindownload.cgi the latest binary for your Linux
if by the time of reading this blog it is one year or more and you by chance have come across and the above link does not works do Google apache ant binary download
I will suggest Google ant apache download and use the latest version because in my case I got this problem from some blog old links were not working

It is a good practise to install these type of packages in
/usr/lib/
(although not necessary)
so you should have some thing like

/usr/lib/apache-ant-1.8.1

Step 5) go back to /etc/profile.d and create
/etc/profile.d/ant.sh and its content will be

export ANT_HOME=/usr/lib/apache-ant-1.8.1
export PATH=$ANT_HOME/bin:$PATH

Step6) I installed in /usr/lib both Jdk and Ant so my JAVA_HOME and ANT_HOME are like that.

upto this step do a check
echo $JAVA_HOME
you should get
/usr/lib/jvm/java-6-sun
and

root@tapas-laptop:/etc/apt# echo $ANT_HOME
/usr/lib/apache-ant-1.8.1

Step 7) If you do not get upto the above mentioned steps 6 then do not proceed further first resolve the above issues.
Here are a few links which I feel will be useful to you since I had problems from Step1 to Step6 which got resolved
following links you can read
http://ubuntuforums.org/showthread.php?t=1543461
http://ubuntuforums.org/showthread.php?t=1543461

Step 8) Assuming that if you type which java and which ant on command prompt you are getting following output
root@tapas-laptop:/etc/apt# which java
/usr/lib/jvm/java-6-sun/bin/java

root@tapas-laptop:/etc/apt# which ant
/usr/lib/apache-ant-1.8.1/bin/ant

Step 9) Check ant -version

you should get an output like this

root@tapas-laptop:/etc/apt# ant -version
Apache Ant version 1.8.1 compiled on April 30 2010

Step 10) check java -version

root@tapas-laptop:/etc/apt# java -version
java version "1.6.0_13"
Java(TM) SE Runtime Environment (build 1.6.0_13-b03)
Java HotSpot(TM) Server VM (build 11.3-b02, mixed mode)

Step 11) If upto above you have got exactly what mentioned only then proceed further.
Otherwise resolve the above errors first.

If you get an error like
Error: JAVA_HOME is not defined correctly. We cannot execute /usr/lib/jvm/java-6-sun/bin/bin/java

check this thread

http://ubuntuforums.org/showthread.php?t=1543461

or if you get an error like

ant

Unable to locate tools.jar. Expected to find it in /usr/lib/jvm/java-6-sun-1.6.0.13/lib/tools.jar
Buildfile: build.xml does not exist!
Build failed

check this thread
http://ubuntuforums.org/showthread.php?t=1543461

Step 12) Install subversion
apt-get install subversion

you do not need to know what subversion is to be able to use it although it will help if you know it
When I used I did not knew what it is.

Step13) Now go to http://code.google.com/p/red5/
http://code.google.com/p/red5/source/checkout
since they can move the repositories if you hit this blog at a later date and then do Google svn red5 trunk

Step 14)
Go to /opt (not necessary to be in opt but I prefer)
type following command
svn checkout http://red5.googlecode.com/svn/java/server/trunk/ red5-read-only

after some minutes depending upon your internet connection you will see a directory named

red5-read-only in /opt or where ever you executed this command say for example you executed
svn checkout http://red5.googlecode.com/svn/java/server/trunk/ red5-read-only
from your home directory i.e.
/home/user
then you will see
/home/user/red5-read-only

Rename red5-read-only to red5
If you do not know how to rename do following from your
directory where you executed svn command

mv red5-read-only red5

Step 15) now go to /opt/red5 and type
cd /opt/red5
and type
ant

please note if you get an error like this

Buildfile: /opt/red5/build.xml
BUILD FAILED
Target "build" does not exist in the project "Red5".

then you do not need to type ant build for building any thing
just type ant from /opt/red5 and the above error should go I got this information here
http://old.nabble.com/Red5-Linux-installation-problem-td17522740.html
if this does not solves your problem you should Google the error message

Step 16) Thats it.

Now go to /opt/red5/dist and you should see red5.sh
on command prompt ./red5.sh should give you some output do not close the terminal and check in
browser http://localhost:5080/

I have not explained how to create a startup script for this but if you want to read check the following blog
http://www.sherin.co.in/red5-flash-media-server-development-how-to-install-and-configure/
I will post it and give a link to my blog also.
Just want your confusion to be less :)

Compiz fusion icon and Ubuntu 9.04

2010-06-27T16:05:00.001+05:30

I tested Compiz fusion on my Ubuntu 9.04 it was awesome.
Ctrl+Left Arrow gives a cube rotating.

To be able to do this on your Ubuntu 9.04 machine

sudo apt-get install simple-ccsm
sudo apt-get install compizconfig-settings-manager

System - Preferences - CompizConfig Settings Manager

You may need to install fusion-icon from
System->Preferences->Synaptics Package manager

then type ccsm on command prompt
you should get a screen.

Which will ask you preferences for your Desktop background.
You should get such a window

and then go to General in the window select
General options -> Desktop Size and increase the number of desktops to 4.
Or what ever you wish
Ctrl+Alt+Left Arrow should give you effect which you can see on my laptop here

Awesome effect.My laptop is Dell Insprion no hi fi graphics and it works cool.

Now to be able to see cube caps

System-->Preferences-->CompizConfig Settings Manager
|
|------->General Options--->Desktop Size tab
|
|-->Horizontal Virtual Size (4 )
|-->Vertical Virtual Size (1)
|-->Number of Desktops (1)

Then to be able to rotate and see cube you need

Ctrl+Alt+Left Click +Drag mouse

Ctrl+Alt+Left Arrow/Right Arrow will switch cube surfaces.

How it looks on my laptop when I press

Ctrl+Alt+Left Click +Drag mouse

Installing Red5 on CentOS 5.5 64 bit

2010-06-23T15:31:00.005+05:30

Step 1
yum -y install java-1.6.0-openjdk java-1.6.0-openjdk-devel

Step 2
yum install subversion

Step 3

wget http://www.apache.org/dist/ant/binaries/apache-ant-1.8.0-bin.zip

Use the latest version of ant available

before doing wget check if the above link is actually working.
Using the latest ant version will save your life a lot of errors.
I had n number of errors which went away by using them.
If by the time you read this blog this guide becomes old and new releases are available just Google latest ant apache version and use that.

Guides can become obsolete since with new updates new steps might be needed.

unzip apache-ant-1.8.0-bin.zip

mv apache-ant-1.8.0 /usr/local/ant

Do not do yum install ant or
yum install ant-*
because when I did yum install ant
and tried to execute it got following error
Class org.apache.tools.ant.taskdefs.ConditionTask doesn't support the nested "antversion" element

Step 4

export ANT_HOME=/usr/local/ant
ln -s /usr/local/ant/bin/ant /usr/local/bin/ant

Step 5

Check ant version (To make sure ant is working)

ant –version

Step 6

INSTALL Red5
Get latest Red5 :
svn co http://red5.googlecode.com/svn/java/server/trunk red5
Build Red5 :
cd red5
ant prepare
ant dist
Move Red5:
cd ..
mv red5 /opt/red5
OPERATE RED5
cd /opt/red5/dist

Start Red5 (when need or on server reboot):
./red5.sh

Step 7

1. Check if red5 is running:
ps aux | grep red5
2. Go to its folder and shut red5 down:
cd /opt/red5/dist
./red5-shutdown.sh
3. See if it’s still running or not:
ps aux | grep red5
4. Restart it, and also make it output the logs into a file of your choice:
./red5.sh > start.log &
5. Make sure it’s back online:
ps aux | grep red5

Step 8 init script to run at boot
in this case

CREATE INIT FILE

vi /etc/init.d/red5

*create the file and paste the script below than save and close by pressing ESC than typing :wq
Insert Red5 init script

#!/bin/sh
# Startup script for Red5 flash streaming server on RedHat/CentOS (cPanel)
# chkconfig: 2345 95 55
# description: Red5 Flash Streaming Server
# processname: red5

PROG=red5
RED5_HOME=/opt/red5/dist
DAEMON=$RED5_HOME/$PROG.sh
PIDFILE=/var/run/$PROG.pid

# Source function library
. /etc/rc.d/init.d/functions

[ -r /etc/sysconfig/red5 ] && . /etc/sysconfig/red5

RETVAL=0
# above is 0 if you copy paste from this blog and this does not work just replace o above by #zero

case "$1" in
start)
echo -n $"Starting $PROG: "
cd $RED5_HOME
$DAEMON >/dev/null 2>/dev/null &
RETVAL=$?
if [ $RETVAL -eq 0 ]; then
echo $! > $PIDFILE
touch /var/lock/subsys/$PROG

fi
[ $RETVAL -eq 0 ] && success $"$PROG startup" || failure $"$PROG startup"
echo
;;
stop)
echo -n $"Shutting down $PROG: "
killproc -p $PIDFILE
RETVAL=$?
echo
[ $RETVAL -eq 0 ] && rm -f /var/lock/subsys/$PROG
;;
restart)
$0 stop
$0 start
;;
status)
status $PROG -p $PIDFILE
RETVAL=$?
;;
*)
echo $"Usage: $0 {start|stop|restart|status}"
RETVAL=1
esac

exit $RETVAL

Make it executable

chmod a+x /etc/init.d/red5

*usage: /etc/init.d/red5 restart (or start, stop)

Then to be able to see if the script is working or not

use /etc/init.d/red5 start and see in your browser http://IP of server:5080
you should get a red5 working script page.

If you get any problem in executing then probably the copy paste of above script might have given some problem so I have uploaded the script in a text file here on this link
https://docs.google.com/document/edit?id=1dJ40x0mJPaIDXvbMjQQJA6IUBHxhvK2nIYqndFKT1Is&hl=en

Step 9

Always starting at boot Red5
Here is the thread that helped me
http://osflash.org/pipermail/red5_osflash.org/2007-September/015065.html
and steps for this is

Copy the script to /etc/init.d/red5 (chmod 755 red5)

chkconfig --add red5

#start on boot
chkconfig --level 345 red5 on

# usage
service red5 start
service red5 stop
service red5 restart

Step 10
The following is an important blog which helped me for Red5 I modified the script on the blog
init script to run red5 at boot
http://www.chatroulette-clone.com/questions/faq/installing-red5-cpanel/
if some one wants to have a look on it.
Should help them.

Pxe boot installation for Ubuntu

2010-05-15T17:22:00.000+05:30

On many blogs on internet it says
"If you have the cd or cd image mounted in /var/www/ubuntu, then you will have material for netboot here: /var/www/ubuntu/install/netboot/"

but that is not the case
That is exactly where the problem is the instead it has a directory named casper where it has initrd and vmlinuz some where I read for this I need a Live CD of Ubuntu
in the install directory I have following only
root@tapas-laptop:/mnt/install# ls
mt86plus README.sbm sbm.bin

Just check the following link I downloaded netboot from Ubuntu Jaunty repositories from here
http://archive.ubuntu.com/ubuntu/dists/jaunty/main/installer-i386/current/images/netboot/
they have an image named mini.iso

Finally I found a solution the CDs named alternate have the netboot folder this is what is needed.

TFTp settings on Ubuntu I forgot but had discussed some thing here
http://ubuntuforums.org/showthread.php?t=1331410

I kept in /var/lib/tftpboot the files related to installtion
the TFTP settings for booting via network
Following changes were made to config files

First file
/etc/inted.conf
tftp dgram udp wait root /usr/sbin/in.tftpd /usr/sbin/in.tftpd -s /var/lib/tftpboot
## netbios-ssn stream tcp nowait root /usr/sbin/tcpd /usr/sbin/smbd

Second file
/etc/default/atftp
USE_INETD=true
OPTIONS="--tftpd-timeout 300 --retry-timeout 5 --mcast-port 1758 --mcast-addr 239.239.239.0-255 --mcast-ttl 1 --maxthread 100 --verbose=5 /var/lib/tftpboot"

Third file
/etc/default/tftp-hpa

#Defaults for tftpd-hpa
RUN_DAEMON="yes"
OPTIONS="-l -s /var/lib/tftpboot"

Fourth file I touched was
/etc/default/xinetd

# Default settings for xinetd. This file is sourced by /bin/sh from
# /etc/init.d/xinetd

# enable xinetd Inetd compat mode
INETD_COMPAT=Yes

# Options to pass to xinetd
#
# -stayalive comes by default : it can be removed if xinetd is expected
# not to start when no service is configured
#
XINETD_OPTS="-stayalive"

Then 5th file
/etc/dhcp3/dhcpd.conf
/etc/dhcpd.conf
ddns-update-style none;

Most probably when you delete an existing VM and create a new with same name LVM shows that it is no more infact that is what is causing problems.So to my surprise change of name had worked.

A strange problem using QEMU

--------------------------------------------------------------------------------------------
I am facing one more problem during the installation.If I press a key
once after some time I see the effect in QEMU screen there is some
delay and after this delay the effect of pressing the key is as if I
have clicked multiple times.Say
I have to enter the gateway address 192.168.1.2
If I press 9 or any of the above digit once
rather than typing
192.
it types
199999999999999999 and then after some time it releases the cursor to
type any thing.
to choose between two menu
---> press cancel
|
|
yes no
If I choose yes it clicks many times automatically yes and goes back
to previous menu and then comes again to forward menu so back and
forth switching between menus.
Which makes it very difficult to move ahead it has been two hours but
I could not proceed at all with this.
More over the response is coming very slow if pressing any key stroke
from my laptop because of which I have to wait for a long time to get
the response and move to another menu.

I am not using the GUI based installer it is a text based install.If I
use a GUI it is very very slow and have to wait for a very long time
for the response to come.
For example clicking on License agreement you agree yes
to do so it takes a very long time which it is not taking in text mode
but the above problem of seeing the effect multiple times in an
undesired way and slow response is there.
This is not a consistent situation but occurring at irregular
intervals.This has made my work very slow.
Is there any way to get rid of this?

Grails apache geronimo some problem in deploying debian

2010-05-04T17:43:00.000+05:30

I want to deploy a web application that is made using grails.
By reading documentation I came that has to be converted to a .war format file.
This file has a deployment plan which comes in two XML files.

Right now I failed to deploy the application on the geronimo server.

I went through
https://cwiki.apache.org/GMOxDOC22/creating-deployment-plans-for-web-applications.html
http://java.sun.com/xml/ns/javaee/
http://geronimo.apache.org/xml/ns/j2ee/web-2.0.1

Troubleshooting J2EE asset deployment
http://publib.boulder.ibm.com/wasce/V1.0.1.1/en/Tasks/Deploy/Trouble.html

I did read all of the above links but I was not able to created xml
files to deploy them as specified.Upto this point I infer that the
problem is coming from deployment plan.

A solution that after came to mind to is create the website
using an IDE like Eclipse on a laptop or so and then that IDE will
take care of deployment plan which may have errors that I am right now
not able to find.

Then that application can be deployed on the server.Since I do not
have a GUI on server so it is not possible right now to do that way on
server.

Here is a link to what I am saying.
http://www.ibm.com/developerworks/opensource/library/os-gerplug/index.html

Since the helloworld script war running successfully on grails server
so it comes to either the way deployment is done or the deployment
plan that refers to XML files.

you have to edit the /etc/apache2/apache2.conf and, at the end of the file, add:

# added servername to avoid the could not determine fqdn error
servername myserver

place your server name in place of myserver.

it worked for me.

Following text is on this link
http://lists.us.dell.com/pipermail/linux-poweredge/2010-April/041936.html
How do I test whether network-script is running or not in Xen Dom0.
I have a Debian Lenny Dom0.Running Xen on it and 4 virtual hosts on it.
I am currently setting up a proxy server in Dom0 which DomU's will be
able to use.The problem is before I go on to set NAT I wanted to test
bridges.

So I renamed the bridge in /etc/xen/xend-config.sxp
Code:

(network-script 'network-bridge bridge=ABCD')

but when I do a reboot or xend restart and do following

Code:

openworld:/etc/xen# brctl show
bridge name bridge id STP enabled interfaces
eth2 8000.0026b9824238 no peth2
vif1.0
vif2.0
vif3.0
vif4.0
openworld:/etc/xen#

the bridge is not renamed to ABCD above output is showing eth2 which
is not even default.
So I doubt that the script network-bridge has not been called so that
it renames the bridge or there is some thing else I should look for.

I had set up a dummy network interface on Dom0

dummy0
modprobe dummy0
then in Dom0 /etc/network/interfaces
added the ip to dummy interface.

in network-bridge netdev=dummy0') was set so that it was used.
brctl was showing this dummy and then a simple POSTROUTING configuration.

Sol
My general technique for seeing what's up with the script in a case like
this is to insert at the top:
set -x
exec &>/tmp/network-script$$

Then you'll get a file with the pid on the end every time it's executed,
with an exec trace. Don't forget to clean up the /tmp files and the
script when done.

Some one is talking here not read myself completely how helpful is it.

Following error messages were encountered while installing vim

Since release 150, udev requires that support for the CONFIG_SYSFS_DEPRECATED
feature is disabled in the running kernel.

Please upgrade your kernel before or while upgrading udev.

AT YOUR OWN RISK, you can force the installation of this version of udev
WHICH DOES NOT WORK WITH YOUR RUNNING KERNEL AND WILL BREAK YOUR SYSTEM
AT THE NEXT REBOOT by creating the /etc/udev/kernel-upgrade file.
There is always a safer way to upgrade, do not try this unless you
understand what you are doing!

So a clean sources.list file is needed.

Compiling Xen from sources on Debian

2010-04-07T15:09:00.001+05:30

Some one explained me in detail on community so I am forwarding same here
This guide will explicate in detail about the procedure for compiling
vanilla kernel from source and customize it according to your hardware
specifications and then compiling latest XEN from source and patching
it with Linux.
First install these packages:

sudo apt-get install iproute bridge-utils gcc make gettext
sudo apt-get install libcurl4-openssl-dev è openssl
sudo apt-get install python-dev zlib1g-dev bcc libsdl-dev pciutils-dev
è zlib

First we will compile latest XEN Hypervisor from source.

Go to http://www.xen.org/products/xen_source.html and download the
latest XEN hypervisor from there. [Version 3.4.1 at the time of
writing the guide]
Xen 3.4.1 is available WITH and WITHOUT 2.6.18 dom0 kernel. We need
the version without dom0 linux because we will compile our own vanilla
kernel.
I am seting up XEN 3.4.1 on amd64 hardware and running debian
distribution on it with upgraded kernel.
My hardware specifications:
unme -a
Linux -04 2.6.31.4-user-kvm-vanilla #1 SMP Wed Oct 21 16:35:11 BST
2009 x86_64 GNU/Linux
Build / Install Xen

1. mkdir /home/tapas/xen
2. cd /home/tapas/xen
3. tar -xzf xen-3.4.1
4. cd xen-3.4.1
5. make xen
6. make install-xen
7. make tools
8. make install-tools

Build Vanilla kernel
Now we will build th PV_Ops Kernel. The Vanilla kernel source will be
downloaded from Jeremy's tree. Jeremy's git tree on kernel.org
contains the pv_ops dom0 patches. If we use Jeremy's tree then we do
not any extra patches to bind XEN with kernel source.

1. mkdir /home/tapas/linux
2. cd /home/tapas/linux
3. git clone git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git
4. linux-2.6-xen
5. cd linux-2.6-xen
6. git checkout origin/xen/master -b xen/master
7. make menuconfig [see Note below]
8. make-kpkg clean
9. CONCURRENCY_LEVEL=N fakeroot make-kpkg --initrd
--append-to-version=-custom kernel_image kernel_headers
10. This will make the debian packages in the parent directory which
you can install

Note: Please choose the following xen specific optiions in kernel configuration.

Install these debian packages using
sudo dpkg -i
Add the following line to /etc/fstab

none /proc/xen xenfs defaults 0 0

and reboot the machine.

After installing the debian packages, the Grub Entry will look like
the following:
title Xen 3.4.1 / Debian GNU/Linux, kernel 2.6.31.4-tapas-xen-4
root (hd0,0)
kernel /boot/xen-3.4.1.gz
module /boot/vmlinuz-2.6.31.4-tapas-xen-4 root=/dev/sda1 ro
console=tty0
module /boot/initrd.img-2.6.31.4-tapas-xen-4

Hope that will help.

Note that file-backed VBDs may not be appropriate for backing I/O-intensive domains. File-backed VBDs are known to experience substantial slowdowns under heavy I/O workloads, due to the I/O handling by the loopback block device used to support file-backed VBDs in dom0. Better I/O performance can be achieved by using either LVM-backed VBDs (Section 6.3) or physical devices as VBDs (Section 6.1).

JAVA on Ubuntu 10.04 server edition

2009-07-01T14:45:00.000+05:30

I got this error when I tried to install java on Ubuntu 10.04
apt-get sun-java6-sdk

E: Package sun-java6-jdk has no installation candidate ubuntu 10.04

to get rid of this I added

sudo add-apt-repository "deb http://archive.canonical.com/ lucid partner"

sudo apt-get update
sudo apt-get install sun-java6-jdk

and then I was able to install

Then I need to set JAVA_HOME and JRE_HOME
find where is java

so I did
Step 1)
find / -name java

I got

/usr/bin/java
/usr/lib/jvm/java-6-sun-1.6.0.20/bin/java
/usr/lib/jvm/java-6-sun-1.6.0.20/jre/bin/java
/usr/lib/jvm/java-6-openjdk/bin/java
/usr/lib/jvm/java-6-openjdk/jre/bin/java
/usr/share/java
/var/www/efront/www/editor/tiny_mce_new/plugins/java
/var/www/efront/www/editor/tiny_mce/plugins/java
/var/www/efront/www/content/lessons/1/java
/var/www/atutor/tools/packages/scorm-1.2/java
/var/lib/dpkg/alternatives/java
/etc/ssl/certs/java
/etc/alternatives/java
/etc/bash_completion.d/java

in second line is java6-sun that is what I needed

Step 2) in /etc/profile added following lines

JAVA_HOME=/usr/lib/jvm/java-6-sun-1.6.0.20/bin
JRE_HOME=/usr/lib/jvm/java-6-sun-1.6.0.20/jre/bin
PATH=$JAVA_HOME:$JRE_HOME:$PATH

Step 3 ) Note in above I have kept JAVA_HOME before $PATH in third line so as to give priority to sun java on the default java of Ubuntu.
In other wise case it will first search for /usr/bin/java and not
/usr/lib/jvm/java-6-sun-1.6.0.20/bin/java
which is what I need.

Install Linux from ISO image on hard disk without using a DVD ROM or CD Drive

2007-10-01T00:49:00.000+05:30

I am describing here a method to install Linux without using a DVD ROM or CD Drive I have checked it myself .In case you do not follow or could not work as said write a comment here might be some thing is missing I will reply but since I have been searching for a job from past many days so if I do not reply to your queries right now so you have to wait for some time in case

there are many ways to do so
you can install Linux by
1) booting from the network
2) Having a ISO image on your hard disk
3)Boot from USB
4) Installing a linux system from scratch by building your own

I am assuming that Linux is not installed on your system and neither grub or lilo is there
This method is taking Open Suse 10.2 Image but is same for Fedora or Debian or any other distro .
There is one check point in case you used Nero to copy CD or DVD image then it might have been possible that you copied the image and it is file with dot nrg extension in that case you need to get the ISO from NRG

I have installed by all the above methods but I am describing here the simplest one since there are many new comers who would not be able to understand other methods .Before doing all this make sure
1)that you have enabled the option of viewing file extensions in View Options of folder view.
2) If you use Fedora or any other distributions do not use the NTFS partition to store the
image although Open Suse 10.2 can work from NTFS partition I have done it using NTFS
partition only but will not suggest you to do same
3) Most important do not install linux on same partition on which you have the ISO from which you are installing everything since it will format that hard disk that holds the image you are using
there is an image named openSUSE-10.2-GM-DVD-i386.iso which you would have downloaded rename it to suse.iso (not necessary to do so but will make your life simple )

Similarly for any other linux distro you might have image of fedora or debian etc rename them to some simple filename.
the image is 3.6 GB then download the grub for dos from
http://sourceforge.net/projects/grub4dos

Before some one reads the following lines just informing while you install winzip or winrar by default they are associated with ISO filetype so you may see your downloaded ISO as an icon that says it can be extracted via Winrar just go and disable this in options tab from Winrar menu if u want to burn the ISO directly to CS just go to Nero and select burn image to disk and select the ISO u do not need to make it a bootable CD or DVD.

extract the downloaded grub4dos using winzip or winrar ,you will get a folder name grub copy it to C drive
then create a folder name boot in C drive of your windows partition (C drive is not necessary but makes life simple ) .
Now copy grldr from grub to C:

add a line C:\grldr="Start Linux" to
your boot.ini (even if I have mentioned the README there says it all)

Now different distributions of Linux have different kernel names like
Fedora: vmlinuz and initrd.img
Suse: linux and initrd
Mandriva: vmlinuz and all.rdz
Ubuntu: vmlinuz and initrd.gz
Gentoo: gentoo and gentoo.igz
Knoppix: vmlinuz and initrd.img
Slackware: bzImage and initrd.img
Debian: vmlinuz and initrd.gz

use winrar to navigate the ISO image you will go inside folder name boot or where ever the kernel are in your CD or DVD ISO

NOTE ( I took Open Suse 10.2 inside the installation media there was a boot folder inside it was a loader path is openSUSE-10.2-GM-DVD-i386.iso\boot\i386\loader
that had kernel image named linux and the initrd name initrd both are needed)

copy the kernel images vmlinuz and initrd.gz which you see by winrar in ISO archieve from your ISO to folder boot in C drive
both files vmlinuz and initrd are required for any linux system to boot

you can use winrar to view files and extract only two files rather than extracting whole ISO

then you don't need to do any thing just restart the computer and you will get a screen that says
Microsoft Windows XP
Start Linux

choose the option start linux
then go to grub you will find an entry that says command prompt

use command prompt since even after making changes as said in README some times it did not worked
press enter to select the command prompt option
you will get a grub shell showing some thing like this
grub >

now type on grub prompt (grub> ) Note u do not need to type grub > it is already there on your screen if not you did some mistake

In my case it was suse so
grub >kernel (hd0,0)/boot/linux
grub >initrd (hd0,0)/boot/initrd
grub >boot

If you are using some other distribution then above commands will change like this
grub >kernel (hd0,0)/boot/vmlinuz (depending upon your kernel name)
grub >initrd (hd0,0)/boot/initrd.gz (depending upon your initrd name)
grub >boot

press enter then
now kernel will load and will ask you to choose the medium to boot from choose the medium hard disk it might give some error that insert CD just ignore it if it asks to hit back button then it that then choose the medium etc and then choose the hard disk partition to boot from then it will ask for the file name enter suse.iso in the partition where you have it then press enter if you did every thing right installation will start if you messed up then probably you might get an error like boot.catalog not found or some other error like this only
installation starts it might display some error messages just ignore them and press enter
or hit Back button then choose language keyboard installation then choose installation medium
it gives 3 options
CD
Network
Hard disk
choose the hard disk and then from the hard disk choose the correct partition where you copied the 3.6 GB suse.iso
not do not format the same partition on which image is there

By looking at the above procedure do not get confused by the network installation procedure which is quite different from
the normal ones you can read complete method of Network booting and PXE intallation on my blog

2007-09-21 10:16:39 vlc-devel-0.8.6c-3.2.i586.rpm installed ok

these are the files that were downloaded when you had added to yast --> software management-->vlc in sources and packages section

you can manually download all these files that I have explained here in this tutorial

make a folder named vlc in /root i.e. #mkdir /root/vlc/

download the following files for vlc in /root/vlc from site http://download.videolan.org/pub/videolan/vlc/SuSE/10.2/i586/

a52dec-0.7.4-2.2.i586.rpm
libmpeg2-0.4.1.1149-3.1.i586.rpm
libdvbpsi-0.1.5-1.2.i586.rpm
libmad-0.15.1b-2.2.i586.rpm
lame-3.97-3.1.i586.rpm
faac-1.25-2.2.i586.rpm
faad2-2.5-2.2.i586.rpm
x264-0.54.598-2.2.i586.rpm
ffmpeg-0.4.9.9778-4.1.i586.rpm
vlc-0.8.6c-3.2.i586.rpm
vlc-devel-0.8.6c-3.2.i586.rpm

now take your installation DVD or CD and copy the following dependencies from them i586 and no arch folders to /roor/vlc directory

rest of the files that I have mentioned are on the DVD or CD of Open Suse 10.2 there are two separate folders go to i586 folder inside directory sue you will get following files

libcddb-1.3.0-11.i586.rpm
libdvdnav-0.1.10-34.i586.rpm
libdvdread-0.9.6-21.i586.rpm
libmspack-0.0.20060920alpha-10.i586.rpm
xosd-2.2.12-38.i586.rpm
libraw1394-1.2.1-20.i586.rpm
libcdio-0.77-15.i586.rpm
libdc1394-2.0.0-21.i586.rpm
libsexy-0.1.5-37.i586.rpm
wxGTK-2.6.3.3-30.i586.rpm
notification-daemon-0.3.5-23.i586.rpm
vcdimager-0.7.23-39.i586.rpm
libnotify-0.4.2-22.i586.rpm

now go to noarch folder of suse directory you will get these 2 files
freefont-0.20060718-28.noarch.rpm
iso-codes-0.49-38.noarch.rpm

Now just go to /root/vlc where you have made your backup for these repositories and just install these rpms

Network Installation Tutorial for Open Suse 10.2

2007-08-21T10:13:00.001+05:30

I am writing this small tutorial for Installing Linux on network since it was harrowing task for me so I wish some one might benefit from it
I have taken Open Suse 10.2
but the steps would rather be same for most of the distributions In case you are not willing to read the whole tutorial go to the end of it and see the check list might be that is sufficient for you and some commands are given there

-----------------------------------------------------------------------

depending on the boot sequence configured in the computer’s BIOS
The Preboot Execution Environment (in short PXE) is a protocol that enables a computer to be booted on the network.
PXE is saved in ROM on newer network cards some cheap boards do not support it ,
so before you do all this just check wether your board is capable of booting on LAN

To Start with you need

* PXE boot capable machine
* SUSE DVD or CD or ISO files.
o dhcp-
o tftp - to share the boot image
o syslinux - to supply the boot image (pxelinux.0)

Open Suse 10.2 yast2 tftp-server is the correct format do not use the "-" after yast2 instead type without first dash
yas2 tftp-server (note the presence of space and dash -)
yast2 dhcp-server
yast2 nfs-server

o yast2-tftp-server - Graphical configurator for a TFTP server (note in these commands in
o yast2-dhcp-server - Graphical configurator for a DHCP server
o yast2-nfs-server - Graphical configurator for a NFS server.

to see wether DHCP running or not type
rcdhcpd status

-------------------------------------------------------------------------------------------------
In case you don't have syslinux go to software management and install it from your DVD in case of CD it will tell u appropriate CD to use

before doing all this just check that
DHCP
TFTP
NFS
syslinux
are installed on your machine

-----------------------------------------------
You will also tell PXELINUX to boot the linux kernel we will copy from the openSUSE 10.2 DVD.
in case u dont have a TFTP directory in / then make it and then issue following command
cp /usr/share/syslinux/pxelinux.0 /tftpboot

then from Suse 10.2 DVD or first CD u can copy kernel images to boot from
cp /media/SU1020.001/boot/i386/loader/initrd /tftpboot/
cp /media/SU1020.001/boot/i386/loader/linux /tftpboot/

Then
mkdir /tftpboot/pxelinux.cfg
cd /tftpboot/pxelinux.cfg
touch default
chmod 777 default
-----------------------------------------------------------------
The boot configuration in the file default should be as follows:

default linux
label linux
kernel linux
append initrd=initrd install=nfs://IP Of SUSE TFTP SERVER/media/SU1020.001
implicit 0
display message
prompt 1
timeout 1

Note in above files I have used /media/SUSE1020.001
you need the DVD inside the DVDROM for this in case you know how to mount the ISO
you can replace with your own installation directory skip the next step if you dont know how to mount an ISO

Skip the following step if you are first time doing network boot
----------------------------------------------------------------
mount -t iso9660 /windows/E/openSUSE-10.2-GM-DVD-i386-iso/openSUSE-10.2-GM-DVD-i386.iso /install -o loop

where /install is the directory where you want to mount the ISO image and
then go to NFS server settings share this /install ( int this the ISO is already mounted you can check that)
then go to /tftpboot/pxelinux.cfg/default and here change the entry
install=nfs://IP of ur TFTP server/directory that has your ISO mounted/ (Note / at last is required

and then also you can boot this is a general process
to create your own boot menu i.e.
to install Fedora Core 5 ,Debian,Windows at the same time on different machines a file called boot.msg can be created and appropriate changes can be done but that is so confusing that I am not mentioning here
------------------------------------------------------------------------------------------

but with this configuration the dhcp server won’t know about the existence of the tftp server, so we have to add 2 the next-server and filename options. Finally the configuration should look like this:
configure the DHCP and add the following lines in it

next-server IP of TFTP server;
filename "pxelinux.0"

option domain-name ;
mydomainname;;
ddns-update-style none;
default-lease-time 14400;
subnet 192.168.0.0 netmask 255.255.255.0 {
range 192.168.0.1 192.168.0.254;
default-lease-time 14400;
max-lease-time 172800;
next-server 192.168.0.1;
filename "pxelinux.0";
}
--------------------------------------------------------------------------------------
Sample dhcp.conf where TFTP server IP is 44
option domain-name "IPG2004";
option domain-name-servers 192.168.0.44, 192.168.0.44;
option routers 192.168.0.44;
ddns-update-style none;
default-lease-time 14400;
subnet 192.168.0.0 netmask 255.255.255.0 {
range 192.168.0.1 192.168.0.254;
default-lease-time 14400;
max-lease-time 172800;
next-server 192.168.0.44;
filename "pxelinux.0";
}
------------------------------------------------------------------------------------------------
Sample "default" file in directory /tftpboot/pxelinux.cfg

default linux
label linux
kernel linux
append initrd=initrd install=nfs://192.168.0.44/install/
implicit 0
display Hi This is Tapas Linux
prompt 1
timeout 1

------------------------------------------------------------------------------------

In case any thing goes wrong
1) check syslinux was installed to check type as root
#rpm -q syslinux
the output would tell wether syslinux was there or not
2)the client machine should be enabled in BIOS to boot from Network press F12 or F10 to boot from Lan if you see a DHCP request on your machine then the DHCP server is up and running
3)check DHCP server is on and running
4)check TFTP server in xinetd services is running or not
5)check NFS entries in which file has been exported is it the same as the files in installation DVD
6 )check the IP of your DHCP and TFTP server in
/etc/dhcp.conf and /tftpboot/pxelinux.cfg/default
also check the file nams specified
7)check the image that you have mounted is at having chmod 777 permissions in /install directory
8) in case you are using a firewall and you are a newbie then it is better you disable the firewall expert people might check the iptables to see they have allowed above services
9) In case you are getting non graphical screen to install on client machine that means that ROM on your Lan card does not have enough memory to support graphical installation
or the entries in NFS server on the TFTP machine or DHCP or NFS where ever is your exported directory are in suscpicion

disable the hidden administrative share

2007-08-07T19:53:00.000+05:30

You can disable the automatic administrative share creation via Group Policy, but this is a much simpler way:

In order to disable these shares permanently, a registry edit will be necessary.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanManServer\Parameters

create AutoShareServer AutoShareWks both REG_DWORD Value: 0

The default-hidden shares are:

C$ D$ E$ - Root of each partition. For a Windows NT workstation/W2K/2003/XP Professional computer only members of the Administrators or Backup Operators group can connect to these shared folders. For a Windows NT Server/W2K Server computer, members of the Server Operators group can also connect to these shared folders.
ADMIN$ - %SYSTEMROOT% This share is used by the system during any remote administration of a computer. The path of this resource is always the path to the W2K/NT system root (the directory in which W2K/NT is installed usually C:\Winnt and in XP it's C:\Windows).
FAX$ - On W2K Server, this used by fax clients in the process of sending a fax. The shared folder temporarily caches files and accesses cover pages stored on the server.
IPC$ - Temporary connections between servers using named pipes essential for communication between programs. It is used during remote administration of a computer and when viewing a computer's shared resources. This share can be very dangerous and can be used to extract large amounts of information about your network, even by an anonymous account.
NetLogon - This share is used by the Net Logon service of a W2K, 2003 and NT Server computer while processing domain logon requests, and by Pre-W2K computers when running logon scripts.
PRINT$ - %SYSTEMROOT%\SYSTEM32\SPOOL\DRIVERS Used during remote administration of printers.

bypass orkut filters

2007-08-02T23:15:00.000+05:30

Ever thought of orkutting on your mobile. How if you can orkut while travelling by bus, train .etc! well, All you need is :-

a GPRS enabled mobile phone
an active internet connection (Mobile Office in case of Airtel) and
mobile application opera mini.

If you try to open www.orkut.com on mobile it fails due to either design of the site or limitations for support of javascript in opera mini. Even orkut says-

Currently, orkut.com isn’t compatible with mobile devices. To access your orkut profile, please try logging in using your computer’s web browser.

But the truth is... I've been orkutting on my mobile for past few months with opera mini using this link. Since the link address is too long, for convenience add, rupeshmandal.googlepages.com/mobileorkut (note: without www) as bookmark.

Previously, i was able to check scrapbook/communities, delete scraps and search but was unable to scrap someone... But recently unplugged showed some tricks to do so. though they are tedious, they do the job.

Note:- make sure you bookmark them correctly else they won't work.

1. To scrap
add a bookmark with name scrap@orkut or anything and address

javascript:{document.forms[1].action += "&Action.submit=";document.forms[1].submit();}

javascript:submitForm(document.getElementById('b2'),'submit');

Now each time you want to scrap someone, go to his/her scrapbook... type the message in the message box (on pressing ok the page tries to load.. you can press cancel .. no problem!)

Now, open the bookmark scrap@orkut. It will post your scrap in the background. you can check out by reloading your friend's scrapbook.

2. Reply from your own scrapbook
add a bookmark with name reply@orkut with address

javascript:{ for (var i = 1; i<=10;i++) { if (document.getElementById("scrapText_" + i).value != "") { document.getElementById("b" + (i*3 +1)).onclick();break;} } }

Now to reply from your own scrapbook, type the message in reply message box and open this bookmark.

3. Sending Message
add a bookmark named as message@orkut with address
javascript:submitForm(document.getElementById('b1'),'submit');

4. Adding a friend
add a bookmark named addfriend@orkut with address
javascript:submitForm(document.getElementById('b1'),'yes');

and open it when asked for confirmation while adding a friend.

5. Joining community
bookmark
javascript:submitForm(document.getElementById('b1'),'join');
with name joincommunity@orkut

open this bookmark when it asks for confirmation.

As i've said earlier, these procedures are quite tedious but they work no doubt. Hope that things will be easier in near future.

unblocking websites

2007-08-02T23:00:00.000+05:30

Opera provides a free online tool called Opera Mini Simulator that emulates the Opera mobile phone browser on your desktop computer. The tool is done in java and is quite popular among web designers for testing website layouts on mobile phone devices without actually using a mobile phone.

As you probably guessed it by now, this Opera Browser Simulator can also be used for accessing web pages that may be blocked on your computer. Since the requests are made via the Opera.com website, they would easily bypass the local filtering.

To open any site in Opera, just append that site address to the following URL and start browsing.

http://www.operamini.com/demo/?url=[URL] - example

The Opera Simulator can even be used for secure sites that require cookies - for instance, you can check your Hotmail emails via Opera. Though you are restricted to the tiny 200x200 screen of Opera simulator, it's still a very handy tool. [Opera link

Is anyone else reading your email ?

2007-08-02T22:49:00.000+05:30

Is your boss or even some coworker secretly reading your email ? Are the Federal agencies snooping your email messages ? Following are two simple techniques that can help you confirm your suspicion - it detects snoopers and can track the address of the computer that is watching your email.

Remember that for steps 3 & 4, you can create a free account on geocities.com, create a dummy HTML file that contains Statcounter or Google Analytics tracking script.

1. Set up a Hotmail account in US and and a second email account with a non-U.S. provider. (eg. Rediff.com or IndiaTimes.com)
2. Send messages between the two email accounts which might be interesting to the email snooper or NSA who may be monitoring your email.
3. In each message, include a unique URL to a Web server (link to the dummy file on geocities.com containing the tracking code) that you have access to its server logs. This URL should only be known by you and not linked to from any other Web page. The text of the message should encourage an NSA monitor or email snooper to visit the URL.
4. If the server log file ever shows this URL being accessed, then you know that you are being snooped on. The IP address of the access can also provide clues about who is doing the snooping.

The other technique uses Google Analytics for tracking the email impressions.

1. Create an email email message such that Urchin with the following HTML code to embed the __utm.gif image anywhere in your email message.

The email impressions would be credited to the source "news1" and the medium "email". As soon as someone ones your email, the impression will be registered on Google Analytics server as the gif file is downloaded on the spying computer.

2. If the email recipient has disabled automatic downloading of internet images, you can create a campaign link to track the email referrals. Tag these links using the utm_ campaign variables.

Continuing with the example above of an email message which you track using the source "news1" and the medium "email," your tagged link might look like this:

< href="www.mywebsite.com/?utm_source=news1&utm_medium=email">

Update: According to NYT, the volume of information gathered from telephone and Internet communications by the National Security Agency without court-approved warrants was much larger than the White House has acknowledged.

Americans come to the program's attention only if they have received a call or e-mail message from a person overseas who is already suspected to be a member of certain terrorist groups or linked somehow to a member of such groups. And the agency still gets a warrant to intercept their calls or e-mail messages to other people in the United States.

Useful Windows XP DOS Commands & Tricks

2007-08-02T22:35:00.000+05:30

To view help at the command-line, at the command prompt, type the following:
CommandName /?

Quick tip - Drag to avoid typing: When your command acts on a file or folder, you must type the path to that folder after the command. You can save typing time by dragging the file or folder from Windows Explorer into the command window.

find - advanced file search with filter

fc - Free BeyondCompare in XP
FC is an advanced DOS Command that compares two files and displays the differences between them. Though the file comparison results are not as interactive as BeyondCompare or Altova DiffDog, fc is still very useful. You can even set fc to resynchronize the files after finding a mismatch.

type - open text files sans Notepad
Similar to Unix cat command, Type is my favorite DOS command for displaying the contents of a text files without modifying them. When used in combination with more switch, type splits the contents of lengthy text files into multiple pages. Avoid using the type command with binary files or you'll hear alien PC beeps and see some greek characters on your PC.

Disabling Recent Documents History

2007-08-02T22:24:00.000+05:30

- Windows XP includes a feature that keeps track of all recent documents you have opened or used. The idea is that you can select Start/Recent Documents History and quickly reopen any document you have recently used. I use many documents each day and never use the feature myself. In my opinion, I can keep up with what I want to use without Windows XP doing it for me.

The bad thing about Recent Documents History is that Windows XP has to calculate what should be put there each time you boot Windows, which can slow things down. So, if you never use the Recent Documents History, it's a good idea to disable it. Here's how:

1. Open the Registry Editor (select Start/Run, type regedit, and click OK).
2. Navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows\ CurrentVersion\Policies\Explorer.
3. Create a NoRecentDocsHistory D_WORD key. Double-click the value to open it once it is created.
4. Set the Data Value to 1 to enable the restriction.
5. Click OK and close the Registry Editor. You'll need to restart the computer for the change to take effect.

I have problem of getting up late in the morning and was always late for work. My proff was mad at me and threatened me .#%#%#$ if I didn't do something about it. So I went to my doctor who gave me a pill and told to take it before going to bed.

I slept well and in fact beat the alarm in the morning had a leisurely breakfast and went cheerfully to class .
"Sir," ..................... "The pill actually worked!"

"That's all fine" said the proff. "But where were you yesterday?"

AIEEE 07

2007-06-01T01:10:00.000+05:30

AIEEE 2007 is given by 6 lakh 44 thousand 750 students, according some news in a newspaper
the question is why so much competition ,the jobs that you would get after passing out of any of the institutes would be same you ultimately find yourself in some coaching institute for higher exams like CAT,GRE ,UPSC etc or might be joining any software company that are bulk recruiters
so why the hell is there so much hue and cry.
What matters is your own knowledge not the institute name that you are from your own efforts would take you to success or failure there is no doubt in it .
I myself belong to a prestigious institute and have experienced this fact. You should not take your competitors lighty and if you are not successful in a big exam does not mean you can not succeed
moral of the story is never get discouraged often it is the last key in the bunch that opens the lock

Faster access to network PC's

2007-04-29T11:25:00.000+05:30

I found some thing interesting so here it is when you try to access a computer on a network by its name some time it takes a long time to show the shared files
instead if you open
‘\\computername\foldername’,it opens immediately.probably this occurs when a Windows 2000 system tries to access a Windows 98 system. Thesystem tries to read the scheduled tasks of the remote system—a fairly uselessstep. To solve the problem, open the registry and delete the HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer\RemoteComputer\
NameSpace\{D6277990-4C6A-11CF-8D8700AA0060F5BF} key.
