PDC clusters use Kerberos system for authentification which means you need to tweak your ssh client configuration a little.

General information is avaliable on PDC's "How to login" webpage

Unix-based operating systems

Here's the relevant part of ~/.ssh/config (replace “username” with your username):

Host * *
    GSSAPIAuthentication yes
    GSSAPIKeyExchange yes
Host * * * * * *
    GSSAPIDelegateCredentials yes
Host lindgren
    User username
    GSSAPIKeyExchange yes
Host lindgrenfs
    User username 

Provided that you have kerberos installed in your system, you can then get authenticated using following command and your password:

  kinit -f -l 700h username@NADA.KTH.SE

This command grants you access to any PDC cluster for the following 700 hours (that's roughly one february). You can login to PDC cluster via ssh:


For convenience, it might useful to define similar aliases in your .bashrc:

  alias lin='ssh'
  alias lin-auth='kinit -f -l 700h username@NADA.KTH.SE && lin'
