>However, when running nmap on them, one betrays the port that SSH is running on, and the other does not.

What does betray mean?

>I have shut down iptables on both machines and the behaviour remains this way. What could be the cause?

Public facing machines w/ iptables off?

>Specifically, how can I hide the port that SSH is running on?

So if you want it hidden, you want it not to accept connections from other machines?
#iptables -L

See what's allowed, then if you're not iptable savvy, install/run system-config-security.
Then do not permit connections to that port, unless you provide more info, like do you
Have internal trusted interfaces etc, you will be locked out.

Probably good thing you haven't exposed a possibly bad config.
