Host MYHOST (MYIP) appears to be up ... good.
Interesting ports on MYHOST (MYIP):
PORT      STATE    SERVICE VERSION
50000/tcp open     ssh      (protocol 2.0)
1 service unrecognized despite returning data. If you know the service/version, please submit the following fingerprint at http://www.insecure.org/cgi-bin/servicefp-submit.cgi :

Warning: OSScan results may be unreliable because we could not find at least 1 open and 1 closed port
Device type: general purpose|enterprise|scanner
Running (JUST GUESSING) : Apple Mac OS X 10.5.X (89%), FreeBSD 6.X (88%), PC-BSD (86%), HP embedded (85%)
OS fingerprint not ideal because: Missing a closed TCP port so results incomplete
Aggressive OS guesses: Apple Mac OS X 10.5 (Leopard) (Darwin 9.0.0b4, x86) (89%), FreeBSD 6.0-STABLE - 6.2-RELEASE (88%), FreeBSD 6.2-RELEASE (x86) (88%), FreeBSD 6.2-STABLE - 6.3-PRERELEASE (88%), FreeBSD 6.2-RELEASE (87%), FreeBSD 6.2-RELEASE-p3 (87%), PC-BSD 1.3 (86%), Apple Mac OS X 10.5 (Leopard) (Darwin 9.0.0, PowerPC) (86%), Apple Mac OS X 10.5 (Leopard) (Darwin 9.0.0, x86) (86%), Apple Mac OS X 10.5 (Leopard) (Darwin 9.0.0b5 - 9.1.0) (85%)
No exact OS matches for host (test conditions non-ideal).
