Here is an example of how to ssh to access and then ssh to an SCS Linux Network host:
ssh access.scs.carleton.ca[access2 ~]$ ssh theta02
The authenticity of host 'theta (134.117.27.107)' can't be established.
RSA key fingerprint is db:d3:e6:a1:61:36:e2:1c:87:15:cc:f1:56:6d:19:cc.
Are you sure you want to continue connecting (yes/no)? yes
