Linux at GSI

TIP We are currently migrating all machines from NIS to LDAP/Kerberos. If you have trouble loggin in, please read the Kerberos-topic in our wiki.

We are running Debian GNU/Linux, primarily release 7 (Wheezy) at the moment. For further information on our road-map take a look at the ReleasePlan. Refer to the list of Debian books for a general overview.

NEW People new to the Linux services in GSI should start by reading " First Steps" (in German " Erste Schritte").

Access to the HPC infrastructure using the InteractiveMachines is explained in RemoteAccess and SshUsage.


The HPC Department announces operational issues over the GSI-LINUX-ALL mailing list!

All owners of a LinuxAccount are automatically subscribed to that list.

If you have questions concerning user accounts please contact the User Help Desk (☎ 2515).
