The following command enables Authentication using GSSAPI:

ssh -l BFHusername -o GSSAPIAuthentication=yes

Your home directory won't be mounted unless you delagate your credentials:

ssh -l BFHusername -o GSSAPIAuthentication=yes -o GSSAPIDelegateCredentials=yes

One might argue that this isn't much more convenient than typing its own password… Well, just add the following lines to your SSH configuration in ~/.ssh/config:

Host catbert
User BFHusername
GSSAPIAuthentication yes
GSSAPIDelegateCredentials yes

These options are enabled by default on our PXE-based Linux setup at the TI Biel/Bienne site. You can connect to catbert by simply typing

ssh catbert

It's possible to use wildcards like

Host *

in the SSH configuration - use them at your own risk.



  • You have to install Kerberos for Windows as described on the Kerberos main page, otherwise your credentials won't be delegated, which is needed to mount your home directory.
  • Download (and install) the latest development snapshot from the PuTTY download page.


Enable the options

  • Attempt GSSAPI authentication (SSH-2 only)
  • Allow GSSAPI credential delegation

and make sure that UTF-8 is selected as character set:

Enter BFHusername@catbert.bfh.ch1) under Host Name and save your session settings.

Click Open to connect to (y)our favorite SSH login server!
