Access to the HPC-clusters is limited from outside the TU Delft network for security reasons.
When you use a VPN-connection direct access from your desktop/laptop to the HPC is possible. You can use your application of choice for this connection.
When you don't use a VPN you should connect through a Bastion server, which is described below.
Bastion
The TU Delft offers two bastion servers. These servers can be used to tunnel your traffic to the HPC.
- linux-bastion.tudelft.nl for employees or guests.
- student-linux.tudelft.nl for students.
Console access
Command line
When your desktop/laptop supports ssh from the console, you can connect to the bastion server and from there you can connect to the HPC:
[user@home]$ ssh <netid>@linux-bastion.tudelft.nl
netid@linux-bastion.tudelft.nl's password:
[netid@bastion]$ ssh <netid>@hpcXX.tudelft.net
netid@hpcXX.tudelft.net's password:
Welcome
[netid@hpcXX]$
- Replace <netid> with your NetID (also remove the <>)
- When your a student replace <netid>@linux-bastion.tudelft.nl with <netid>@student-linux.tudelft.nl
- Replace <netid>@hpcXX.tudelft.net with the HPC you are connecting to.
Putty
When your desktop/laptop doesn't support ssh from the console, you can use Putty (it may already be installed).
- Session Settings
Fill in the name of the TU Delft SSH server linux-bastion.tudelft.nl (student-linux.tudelft.nl for students), and select the SSH protocol (port 22):
- Connection>SSH Settings
Select Share SSH connections if possible:
- Session Settings
To store these session settings, go back to the session tab, and save the settings under a session name. To activate a stored session, double-click on the session name:
