[K12OSN] Dumb SSH question

[Duane Wilson]

Hi all,
	When I ssh into my K12ltsp server from somewhere new it says

The authenticity of host '65.183.210.2 (65.183.210.2)' can't be established.
RSA key fingerprint is 00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00. 
(not the real string)
Are you sure you want to continue connecting (yes/no)?


How do I find the RSA key fringerprint on the server to compare with so 
that I can avoid a man-in-the-middle attack?


Thanks,
Duane
