Tunneling ssh to run remote application

Tunnel VNC

ssh -N -f {user}@{router-ip} -L 5901:{domain-ip}:5900
vncviewer localhost:1

to use with web browser

ssh -N -f {user}@{router-ip} -L 5801:{domain-ip}:5800
vncviewer localhost:1

Tunnel HTTP

ssh -N -f {user}@{router-ip} -L 8080:{domain-ip}:80
http://localhost:8080

it also works for remote gforge access through svn
svn checkout http://localhost:8080/svn/{project}

Magic the Gathering (multiplatform)

Just a link for those wanting to play MtG online on linux or mac :
http://mindless.sourceforge.net/

It is said to be compatible with apprentice.

For non rpm based distribution, you can either build it from the source or use alien to convert the rpm file to your distribution package system

under debian or ubuntu

sudo apt-get install alien
wget downloads.sourceforge.net/mindless/mindless-1.6-1.i386.rpm
sudo alien --to-deb mindless-1.6-1.i386.rpm
sudo dpkg -i mindless-1.6-1.i386.deb

The card data base will also be needed, they are not released with the program.

here is a link http://www.magic-league.com/download/10th%20patch.zip
