Connecting to VSC

(DEMO)

[...]$ ssh <me>@vsc3.vsc.ac.at
# dedicated server :
[...]$ ssh <me>@l31.vsc.ac.at
                ..
[...]$ ssh <me>@l35.vsc.ac.at  
[...]$ ssh <me>@vsc4.vsc.ac.at
# dedicated server :
[...]$ ssh <me>@l40.vsc.ac.at
                ..
[...]$ ssh <me>@l49.vsc.ac.at

how to set up ssh-keys on client and login node


DEMO:

[...]$ eval `ssh-agent`     # start ssh agent
[...]$ echo $SSH_AGENT_SOCK # check if it is running
[...]$ chmod 700 ~./ssh     # change rights of .ssh-directioy
[...]$ ssh-keygen -t rsa    # generate key on local machine

will be asked to create a pass phrase. that passphrase must be as secure as your password. IT IS POSSIBLE AT THAT POINT TO GIVE NO PASSWORD, BUT NEVER EVER GENERATE A KEY WHICH IS NOT PROTECTED !!! This may be a hazard for our systemm

[...]$ ssh-copy-id <me>@vsc4.vsc.ac.at # copy key to remote machine

will be asked for password & OTP on VSC-4

Sync and Copy


Sync and Copy

scp <source> <destination>
scp <me>@vsc3.vsc.ac.at:~/<myfile.c> .
scp myfile.c <me>@vsc4.vsc.ac.at:~/
rsync [OPTIONs] <source> <destination>
maybe useful: -av, --exclude=/daten/temp/...

in order to setup on the remote machine, follow: WIKI-link:rsync on remote machines
