SSH Key Integrity
When you log into a client machine for the first time, you should check the integrity of the key. To do that, observe the fingerprint ssh prints out, as in the following example:
$ ssh -x -a masters2.cs.jhu.edu The authenticity of host 'masters2.cs.jhu.edu (128.220.70.22)' can't be established. RSA key fingerprint is 7b:9c:2b:8f:60:5a:1b:fb:30:b0:52:72:0a:18:ee:ce. Are you sure you want to continue connecting (yes/no)?
Before typing 'yes' we recommend that you check the fingerprint against the Grad Net and Ugrad Net tables below.
SSH known_hosts File
RECOMMENDATION: All of the systems' SSH host keys are signed by an internal authority. We recommend that you add the following line to your ~/.ssh/known_hosts file to automatically verify all of our systems' host keys without having to manually check each one individually:
@cert-authority *.cs.jhu.edu ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIOd3xesHEdXkh0XWE4lMNWsNpDP1mK+AoNNSplbEbNpS SSH-CA@cs.jhu.edu
