How do I log into the same login node I used before#
levante.dkrz.de maps to a whole group of nodes to distribute the load:
$ host levante.dkrz.de
levante.dkrz.de has address 136.172.124.7
levante.dkrz.de has address 136.172.124.1
levante.dkrz.de has address 136.172.124.3
levante.dkrz.de has address 136.172.124.6
levante.dkrz.de has address 136.172.124.5
levante.dkrz.de has address 136.172.124.2
levante.dkrz.de has address 136.172.124.4
All login nodes share the same file system so most of the time you do
not have to care which node you are on. However, there are reasons why
you may want to connect to a specific node (for example, to reattach
to a running tmux session). You first have to find out
on which node you are. This may be indicated in your prompt or you can
also use hostname for this purpose:
$ hostname
levante0.lvt.dkrz.de
In this example you are on login node levante0. Connect to this node with:
ssh userid@levante0.dkrz.de
Please keep in mind that login nodes are not intended for long running and computationally intensive tasks. Use batch jobs or interactive partition for this kind of activity.
