Purpose

The purpose of the terminal servers is to provide a standard linux desktop which also gives easy access to the linux grid facilities at DTU Compute. The servers are running a standard Debian 12. Access is software client using thinlinc client [1].The interface is based on the light weight XFCE.

The servers can also be used as directly via ssh clients.

Note: Servers can only be access from DTU network or using VPN. If accessing from outside DTU, both password and ssh key is required.

Hardware

The servers consist of 2 HP servers with 56GB RAM and 24 cores each.

Connecting using a software client

You can either connect using the software client thinlinc freely available from http://www.cendio.com or x2go. The name of the server is thinlinc.compute.dtu.dk. Backup server is thinlinc2.compute.dtu.dk.

Windows/Mac users of x2go should use the fullfonts version.

Ubuntu users of x2go can install it by 

sudo apt-get install x2goclient gsfonts-x11
echo "export LANG=en_US.utf8" >> ~/.bashrc
source ~/.bashrc

en_GB.utf8 can also be used.
