Verifying a Secure Shell Connection (SSH)

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 some kind of 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)?

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

ssh-keyscan  hostname > tmp.pub

ssh-keygen -E md5 -l -f tmp.pub

To verify the integrity of the host, make sure that the public key fingerprint matches those of our corresponding servers:
