Re: [cobalt-security] ssh question

["Kevin D" <kdlists@xxxxxxxxxxxxxxx>]

I don't have any docs in front of me, so I'm not 100% sure, but isn't port
22222 in that range of ports that servers use for dynamic port assignments?
Thus, that port may already be in use by some other program. Try using a
port above 32000 or below 1024 or something like that.
