== Intention ==
  +
* the computer pool is extended by these machines
  +
* the computer pool infrastructue is accessible from remote
  +
  +
  +
=== Target audience ===
  +
These machines are meant to be used by students. But ''of course'' they can be used by any staff members! For new users the only requirement is to logon one single time using one of the (physical) pool computers - this will make them "known" to our systems.

  +
== Usage ==
  +
Simply use SSH to login to this machine:
  +

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

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

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

Timeout

The session Timeout is set to 36 hours


Some technical Details
