After finishing the web registration '''''bwUniCluster''''' is ready for your '''SSH''' based login.
'''''bwUniCluster''''' has two dedicated login nodes. The selection of the login node is done automatically and is based on a round-robin scheduling. Logging in another time the session might run
on the other login node.

Only the secure shell '''SSH''' is allowed to login. Other protocols like '''telnet''' or '''rlogin'''
are not allowed for security reasons.

A connection to '''''bwUniCluster''''' can be established by the command:

<pre>
$ ssh <UserID>@bwunicluster.scc.kit.edu
</pre>

If you are using '''OpenSSH''' (usually installed on Linux based systems) and you want to use a GUI-based application on '''''bwUniCluster''''' you should use the
''ssh'' command with the option ''-X''

<pre>
$ ssh -X <UserID>@bwunicluster.scc.kit.edu
</pre>

'''<UserID>''' of the ssh command is a placeholder for your '''''username''''' at your home
