First set the environment as following

git config --replace --global diff.tool winmerge
git config --replace --global difftool.winmerge.cmd "winmerge.cmd \"$LOCAL\" \"$REMOTE\""

Prepare winmerge.cmd as following as it will be used by git. Make sure its in a path:

cat D:\MyDocs\bin\winmerge.cmd
echo Launching WinMergeU.exe: $1 $2

git difftool

Thats it! Its all set.

django and threading :)

Figured out how to deal threading on django! While there are quite great many argument's and counter arguments, I believe its going to be a great if it doesn't break anything :)

A drop in for the threading:

http://github.com/jaylett/django_concurrent_test_server

Also a proxying solution using django:

http://pypi.python.org/pypi/django-http-proxy/

Looks like I am all set with a desired proxy server :)

SSH Chrooting on Ubuntu 9.10

SSH Configuration Section:

First thing first, setup sshd so that it allows chroot for a given user as following:

Match User jazz
ChrootDirectory /home/jazz
AllowTCPForwarding yes
X11Forwarding no

Next, make sure the directory /home/jazz is owned explicitly on root and no one else:

chown -R root:root /home/jazz

Next execute following:
cd /home/jazz
mkdir etc
mkdir bin
mkdir lib
mkdir usr
mkdir usr/bin
mkdir dev
mknod dev/null c 1 3
mknod dev/zero c 1 5

Execute following:
APPS="/bin/bash /bin/ls"
for prog in $APPS; do
cp $prog ./$prog

# obtain a list of related libraries
ldd $prog > /dev/null
if [ "$?" = 0 ] ; then
LIBS=`ldd $prog | awk '{ print $3 }'`
for l in $LIBS; do
mkdir -p ./`dirname $l` > /dev/null 2>&1
cp $l ./$l
done
fi
done

Please note apps above can be modified as per needed binaries. In a nutshell all the libraries on which binaries depend must be copied to lib, even those libraries depending on libraries must be copied.

Finally copy library as following:

cp /lib/ld-linux.so.2 lib

If you would like to share files between chroot and otherwise use following:

mount --bind /home/ubuntu/Downloads /home/jazz/Downloads

Ofcourse /home/jazz/Downloads must exist!

There chroot should work!

Installing Ubuntu without functioning CDROM, Bootable USB Bios

In a nutshell here are the steps to be executed:

• Assumptions: there is a bootable MBR already present, either though Linux or Windows.
  
• Get a bootable USB drive and the CD image of the ubuntu distribution.
• Install the CD image on the usb drive using software say: PendriveLinux.Com
  
• Make sure that software goes fine, else it may crib about some error if the usb drive is not bootable.
• Get a hold of plop boot loader. This guy allows you to boot to USB drive through its boot loader.
• Reboot into plop boot loader and you are good to go!

Here is the screenshot of plop that should be visible:

Accessing X11 through VNC

Tested in Ubuntu Karmic 9.10

Create following file /etc/xinet.d/x11vnc as following:

service x11vnc
{
port = 5900
type = UNLISTED
socket_type = stream
protocol = tcp
wait = no
user = root
server = /usr/bin/x11vnc
server_args = -inetd -o /var/log/x11vnc.log -display :0 -passwd yourpassword -many -bg
disable = no
}


Make sure it has permission set to 600 for security sake. Restart the xinetd daemon and you are good to go.
