Round 3 and even more strange:


# nmap -sT -O localhost

Starting nmap V. 3.00 ( www.insecure.org/nmap/ )
Interesting ports on localhost (127.0.0.1):
(The 1598 ports scanned but not shown below are in state: closed)
Port       State       Service
7/tcp      open        echo
111/tcp    open        sunrpc
631/tcp    open        ipp
Remote operating system guess: Linux Kernel 2.4.0 - 2.5.20
Uptime 0.786 days (since Tue Jul 29 23:24:53 2003)

Nmap run completed -- 1 IP address (1 host up) scanned in 5 seconds

# ping localhost
PING localhost (127.0.0.1) 56(84) bytes of data.

--- localhost ping statistics ---
12 packets transmitted, 0 received, 100% packet loss, time 11013ms


So where's the black hole?!

(sunrpc and ipp to be checked out later...)
