 === Forwarding the ssh-agent over multiple servers ===
-If the machine to which one wants to login is reachable only over one or several hops in between, the ssh-agent of the local machine can be forwarded to the machines in between using the '-A' option of the 'ssh' command. Prerequisite is that on all remote hosts the public key has been added to the 'authorized_keys' file as described above. For example, a connection to VSC-3 over the 'login.univie.ac.at' machine would look like this :
