Confuse a Scanner!
Labrea + OpenBSD scrub = one very confused response from Nmap.

Interesting ports on xxx.iglou.com (64.253.xxx.xxx):
PORT STATE SERVICE
20/tcp closed ftp-data
21/tcp closed ftp
22/tcp open ssh
23/tcp closed telnet
24/tcp closed priv-mail
25/tcp filtered smtp

Running: 2Wire embedded, Checkpoint Windows NT/2K/XP, Linux 2.4.X, OpenBSD 3.X, Belkin embedded, Sun Solaris 2.X|7|8|9
Too many fingerprints match this host to give specific OS details
Nmap run completed -- 1 IP address (1 host up) scanned in 28.812 seconds
Ports 22 and 25 are redirected to an internal instance of Labrea, which I must say is one nasty piece of software. Love!
