• Minimal x2gosever install guide for RHEL 6

You might have to install add-apt-repository first using:

sudo apt-get install python-software-properties

sudo add-apt-repository ppa:x2go/stable
sudo apt-get update
sudo apt-get install x2goserver

This needs to become more generic and less confusing

First add the X2Go ppa repository for Ubuntu.

After adding the x2go PPA on your remote Ubuntu “desktop” server there are a few general steps to follow to install the x2goserver for use.

Start a ssh terminal session with the remote Ubuntu server.

If you have not copied ssh keys (see x2go wiki section called Advanced x2go Setups) in order to use automatic login by user to the remote server without having to enter their password and instead you plan to require remote users to enter both their UserID and Password on their x2go client then you will need to edit/modify /etc/ssh/sshd_config and change the entry for ChallengeResponseAUthentication from NO to YES then restart ssh (sudo /etc/init.d/ssh restart).

The next step is to install the primary x2goserver packages.

sudo apt-get install x2goserver x2goserver-xsession
