Here's what I get :
# nmap -P0 sandm.hn.org
Starting nmap V. 2.54BETA31 ( www.insecure.org/nmap/ )
Interesting ports on wv-morgantown1-235.mgtnwv.adelphia.net (24.50.80.235):
(The 1550 ports scanned but not shown below are in state: filtered)
Port State Service
22/tcp open ssh
25/tcp open smtp
110/tcp open pop-3
113/tcp closed auth
Nmap run completed -- 1 IP address (1 host up) scanned in 236 seconds
# nmap -P0 -sU -p U:1052 sandm.hn.org
Starting nmap V. 2.54BETA31 ( www.insecure.org/nmap/ )
Interesting ports on wv-morgantown1-235.mgtnwv.adelphia.net (24.50.80.235):
Port State Service
1052/udp open unknown
Nmap run completed -- 1 IP address (1 host up) scanned in 13 seconds
This indicates that SMTP and SSH and POP should work (assuming the
higher-level protocol interaction is correct). It also indicates
that, assuming the ddt client daemon is running, ddt should work.
HTTP might work for some hosts -- all I know is that the port is
"filtered". It might be that all packets are DROPped in which case I
wouldn't know.
If I try to telnet to port 80 I get this odd response with no delay :
$ telnet sandm.hn.org www
Trying 24.50.80.235...
telnet: Unable to connect to remote host: No route to host
but ping works; I don't get "No route to host" when I use it or when I
telnet to port 25. I would have expected either an immediate
"Connection Refused" message or a delay and a "timeout" message.
HTH,
