SSH login from Linux

To log in to the student shell server, edit your ssh settings in ~/.ssh/config to add

Host student-shell
  HostName student-shell.sys.kth.se
  User username
  PreferredAuthentications gssapi-with-mic
  GSSAPIAuthentication yes
  GSSAPIDelegateCredentials yes
  GSSAPIKeyExchange yes

Then log in with

kinit -f username@KTH.SE
ssh student-shell

Note: All examples use username and student-shell – replace this with your KTH username (without @kth.se), and the Shell servers .

Note: If your local Kerberos configuration (e.g. /etc/krb5.conf) uses rdns=false, you should replace the alias student-shell.sys.kth.se with the server's FQDN, student-shell-1.sys.kth.se.

Software

All software is already available in KTH's client platforms. Using a standalone system, you may need to install Kerberos and OpenSSH.

For Ubuntu- or Debian-based distributions, we recommend Heimdal Kerberos (heimdal-clients), but MIT Kerberos (krb5-user) should also work.

For RedHat-based distributions, MIT Kerberos is recommended. For other distributions, see PDC's recommendations .

If prompted for a default Kerberos realm, select "KTH.SE".

## Ubuntu/Debian
[sudo] apt-get install heimdal-clients
[sudo] apt-get install openssh-client

## RHEL/CentOS/Fedora
[sudo] yum install krb5-workstation
[sudo] yum install openssh-clients
