Usage

Simply use SSH to login to this machine:

ssh  user@shell.stud.informatik.uni-goettingen.de

Note that the intially presented banner contains something like

#######  shell.stud.informatik.uni-goettingen.de - login vm: shell5.cip.loc

...telling you the actual local name of the automatically chosen destination machine.


For Windows: use PuTTY (simple) or Cygwin (more complex and powerful) or any other SSH-implementation.


Target audience

These machines are meant to be used by students. But of course they can be used by any staff members! (For first time users: the only requirement is to logon one single time using one of the (physical) pool computers in our building - this will make you a "known user" to our systems.)

Load Balancing

This term is misleading on this specific installation: the default algorithm being used is simply "round-robin" - you'll get connected to the "next" machine one after another. If you landed on an overcrowded system simply disconnect/reconnect to use another machine.

Legacy login.stud

Both login.stud.informatik.uni-goettingen.de and login.informatik.uni-goettingen.de (for staff only) are not affected by this new approach. These "old" machines will continue to work unmodified.

Timeout

  • The session Timeout is set to 36 hours -- this is the HAproxy related Timeout regarding the TCP connection
  • Kerberos/OpenAFS have separate/shorter timeouts. You need to kinit && aklog when you're approaching timeout
