Beta Test. Please give feedback. |

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.
