Connecting to VSC
(DEMO)
VSC-3
[...]$ ssh <me>@vsc3.vsc.ac.at # dedicated server : [...]$ ssh <me>@l31.vsc.ac.at .. [...]$ ssh <me>@l35.vsc.ac.at
VSC-4
[...]$ ssh <me>@vsc4.vsc.ac.at # dedicated server : [...]$ ssh <me>@l40.vsc.ac.at .. [...]$ ssh <me>@l49.vsc.ac.at

ssh-keys — tunneling
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
