Access to bwForCluster BinAC 2 is only possible from IP addresses within the BelWü network which connects universities and other scientific institutions in Baden-Württemberg. If your computer is in your University network (e.g. at your office), you should be able to connect to bwForCluster BinAC 2 without restrictions. If you are outside the BelWü network (e.g. at home), a VPN (virtual private network) connection to your University network must be established first. Please consult the VPN documentation of your University.

Username

Your <username> on BinAC 2 consists of a prefix and your local username. For prefixes please refer to the Username Guide.

Example: If your local username at your University is ab123 and you are a user from Tübingen University, your username on the cluster is: tu_ab123.

Hostnames

BinAC 2 has one login node serving as a load balancer. We use DNS round-robin scheduling to load-balance the incoming connections between the actual three login nodes. If you are logging in multiple times, different sessions might run on different login nodes and hence programs started in one session might not be visible in another sessions.

Hostname Destination
login.binac2.uni-tuebingen.de one of the three login nodes

Login with SSH command (Linux, Mac, Windows)

Most Unix and Unix-like operating systems like Linux or MacOS come with a built-in SSH client provided by the OpenSSH project. Windows 10 and Windows also come with a built-in OpenSSH client.

For login use one of the following ssh commands:

ssh <username>@login.binac2.uni-tuebingen.de

To run graphical applications on the cluster, you need to enable X11 forwarding with the -X flag:

ssh -X <username>@login.binac2.uni-tuebingen.de

Login with graphical SSH client (Windows)

For Windows we suggest using MobaXterm for login and file transfer.

Start MobaXterm and fill in the following fields:

Remote name              : login.binac2.uni-tuebingen.de
Specify user name        : <username>
Port                     : 22

After that click on 'ok'. Then a terminal will open where you can enter your credentials.
