PuTTY

This page explains how to connect to our frontends using PuTTY.

If you want to use graphical applications on our cluster, PuTTY is not the right choice, please have a look at MobaXterm.

1. Open PuTTYgen
2. Click 'Generate' and follow instructions
3. Enter a passphrase for the key
4. Save private key

To upload a key, please log into your account on the GWDG Website, go to “My Account”. Then scroll down to “Other Settings” and click “edit”. You can now add a public key.
You have to use the contents of the top box in PuTTYgen, which is the correctly formatted public key.

1. Open PuTTY
2. Put in Hostname
3. Go to “SSH”
4. Select “Auth”
5. Browse to your key
6. Click Open
7. If you secured your key with a passphrase (which we highly recommend), you will be asked to enter it

If you are outside the GÖNET, e.g. not on campus and are not able to connect to the VPN, you need to use SSH-Agent forwarding to be able to move from login.gwdg.de to one of our frontends.
