[NTLUG:Discuss] RSA Key Fingerprints

[Val Harris]

Guys,

I've just connected to a new SSH server.  As expected, it kicked out the
following message:

The authenticity of host foo.bar.com can't be established.
RSA key fingerprint is d2:ce:c6:1f:70:b8:94:ed:99:26:5d:ff:2d:f4:1d:96.
Are you sure you want to continue connecting (yes/no)?

I chose yes, and everything went on as expected.

My question is:  As admin for the machine named foo, how do I get it to
print it's RSA
key fingerprint for me to compare and verify?  In the future, I may want
to send this
fingerprint to people before they connect to my machine so that they
know they are
connected to foo.bar.com, rather than to sniper.badguys.com trying to
impersonate me.

Thanks, your help is definitely appreciated,

Val
