PuTTY & Pageant 🔗

PuTTY 🔗

You can download PuTTY from https://www.putty.org/ and install it on your machine.

1. Destination Host 🔗

• When you start PuTTY, in the Session menu, you can add the hostname of the palma login node:

  palma-login.uni-muenster.de

• The port will be 22

• You can already type in a name for the new session you want to create (below Saved Sessions ) and click Save.

2. Username 🔗

• In the Connections - Data menu, add your university ID as the login username

3. Private SSH Key 🔗

• In the Auth - Credential menu, add your private ssh key

4. Optional SSH Jumphost 🔗

• If you want to connect to the login node from outside of the university network, you can do so by using a so called jumphost .
• The jumphost can be configured in the Connection - Proxy menu
• For Proxy type, select SSH to proxy and use port forwarding
• Add the hostname of the jumphost: sshjump.uni-muenster.de
• Set the port to 22
• Add your university ID as the username

5. Saving the Session and connecting to the login node 🔗

• Go back to the Session menu and Save your current session to not loose all the settings you just made.
• You can then click on Open to connect to the login node
• The first time you login, you will be asked to accept the connections to the host
• You will also be asked to type in your password for the SSH key.

Pageant 🔗

• Pageant is a small utility to manage your SSH keys
• When you start the tool (search via the Windows Search bar), it will only show a system icon in the taskbar

• Right-Click on the icon and click on Add Key
• Add your private key file

You should now be able to connect to the PALMA login node using PuTTY via the Jumphost if you configured it as explained in step 5 above.
