[Tornado-users] tornado: X-forwarding

[Per Lundqvist]

For your information: the new login node on tornado has a different 
default behaviour when it comes to X-forwarding using ssh. On the old 
login node, you did not have to do anything specifically in order to 
display graphical applications on the analysis node. Now you have 2 
alternatives:

add the argument -X to ssh when logging in to a1:
  ssh -X a1

or add this to ~/.ssh/config on tornado:
  Host a1
    ForwardX11 yes

For this to work, you must log in to tornado.nsc.liu.se using X-forwarding 
- which you had to do before too (either with -X or by setting this in 
~/.ssh/config on the machine you log in from - or if you have root 
privileges, in /etc/ssh/ssh_config)
