To use the terminal:
 
 
* The login shell should be '''/bin/bash''' (most users has this a login shell).
 
* The LANG variable should be set in ~/.bashrc by adding '''*one*''' of the following linies:<br /> export LANG=en_US.utf8<br /> or<br /> export LANG=en_US<br /> Remove the following lines from your ~/.emacs if you set LANG=en_US.utf8:<br />  (set-terminal-coding-system 'iso-latin-1)<br />  (set-language-environment "Latin-1")<br />    (set-keyboard-coding-system 'iso-latin-1)<u><br /></u><u>Reason</u>: SUN, hms1 &amp;linuxgrid has en_US (i.e. a ISO based encoding) as default while linuxterm is having en_US.utf8 as default. By changing to a UTF8 based encoding all text file with special characters such as "æ", "ø" &amp; "å" needs to be updated. This can for latex files be a significant challenge.
 
 
All accounts created since 2013 has LANG=en_US.utf8 as default.

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.
