Login and copy data between HLRN sites

Inter-complex login (ssh) as well data copy (scp) between both sites (Berlin and Göttingen) should work right out of the box. The same is true for inner-complex ssh and scp between nodes of one site. This is enabled through an administratively installed ssh key pair id_rsa[.pub] in your $HOME/.ssh/. Do not remove these keys.

Always use the short hostname for ssh/scp: the generic names blogin, glogin, or the specific names like blogin5, glogin2, etc.

If for some reason this does not work for you for inter-complex ssh/scp, please see the topic Copy between HLRN sites and contact HLRN Support.

Tape archive PERM

Note: PERM is not yet available on Lise

The magnetic tape archive PERM will be accessible via the login nodes blogin[1-9], only:

/perm/{USER}

For more information please see the separate topic on HLRN-IV file systems.
