Verifying a Secure Shell (SSH) Connection

When connecting using ssh for the first time to an unknown host (one of our remote access servers for example) you will be asked whether you trust this host with a prompt similar to this one:

The authenticity of host 'SOMEHOST (N.N.N.N)' can't be established.
RSA key fingerprint is xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx.
Are you sure you want to continue connecting (yes/no)?

To verify the integrity of the host, make sure that the public key fingerprint matches that of the corresponding server listed below. If the fingerprint provided do not match what is listed in the table, you should immediately contact helpdesk@cims.nyu.edu.

Note: To view the fingerprints as we have published them here, use the following ssh commands:

ssh-keyscan hostname | ssh-keygen -E md5 -l -f -
