Any ideas? Thanks! I know the firewall people should be able to tell me but that is worse than pulling teeth, and I would rather find out as much as I can from my end...*if* I can.
Solved! Go to Solution.

Re: Accessible ports script
It seems to me that (s)he who maintains the rules should be able to *recite* the rules! :-))

Re: Accessible ports script
[root@tehran ~]# nmap localhost
Starting nmap 3.70 ( http://www.insecure.org/nmap/ ) at 2006-06-28 13:29 CDT
Interesting ports on tehran (127.0.0.1):
(The 1651 ports scanned but not shown below are in state: closed)
PORT STATE SERVICE
22/tcp open ssh
53/tcp open domain
111/tcp open rpcbind
631/tcp open ipp
953/tcp open rndc
5801/tcp open vnc-http-1
5901/tcp open vnc-1
6001/tcp open X11:1
10000/tcp open snet-sensor-mgmt
Nmap run completed -- 1 IP address (1 host up) scanned in 0.789 seconds
Thats a server in the US. We like to name them after cities in "The Axis of Evil" Poking a little fun.
nmap works great and is standard on Linux. Its instalable or compilable on HP-UX but this is much less fun.
This tool does something called portscanning. This is something that network admins hate. So get permission before you use it.

Re: Accessible ports script
for example
nmap -v 192.168.0.0/24
will scan all addresses in the 192.168.0.0 subnet.
if you change your bit mask to 16 it will be 192.168.0.0 so anything from 192.168.0.0-192.168.255.255

Re: Accessible ports script
If you have many hosts to scan, nmap also accepts a list of hostnames:
nmap -iL
PCS

Re: Accessible ports script
(these folks are really taciturn, probably a symptom of their trade?) you should rather talk to them before you open fire with a port scanner on their firwalls.
Apart from the spurios trafic you generate you could inadvertently trigger of some bogus alerts.
nmap is a very powerful tool and has sophisticated methods of randomizing and stealthing its scans as you may read in its manpage.
