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.
- SCP ist veraltet, Beispiele sollten
rsync
benutzen.
