BinAC/Login
Login
After registration (registration procedure at bwForCluster User Access, the bwForCluster BinAC can be accessed via a Secure Shell like ssh on Linux and Mac or PuTTY on Windows systems.
From linux machines, you can log in using
ssh <UserID>@login01.binac.uni-tuebingen.de ssh <UserID>@login02.binac.uni-tuebingen.de ssh <UserID>@login03.binac.uni-tuebingen.de
To run graphical applications, you can use the -X or -Y flag to openssh:
ssh -Y -l <UserID> login01.binac.uni-tuebingen.de ssh -Y -l <UserID> login02.binac.uni-tuebingen.de ssh -Y -l <UserID> login03.binac.uni-tuebingen.de
For better performance on slow connections you should use e.g. VNC.

Allowed activities on login nodes
The login nodes are the access point to the compute system and its $HOME directory. The login nodes are shared with all the users of the cluster. Therefore, your activities on the login nodes are limited to primarily set up your batch jobs. Your activities may also be:
- compilation of your program code and
- short pre- and postprocessing of your batch jobs.
To guarantee usability for all the users of the bwForCluster you must not run your compute jobs on the login nodes. Compute jobs must be submitted as Batch Jobs. Any compute job running on the login nodes will be terminated without any notice.
Password Reset
If you forgot your password for the bwForCluster BinAC you can set a new one on the BinAC service page. Just use the link in the "bwForCluster BinAC" service box.
