Very strange nmap scan results

Subject: Very strange nmap scan results
Date: Fri, 21 Sep 2007 08:16:43 -0700 (PDT)

Hi all,

For a client in scaning his Dmz from the internet.

I know the servers are behind a pix 515 without any
add security features ( they dont have any ips or
the
didnt enabled the ips feature of the pix). they also
dont have any honeypot etc..

the strange is that two I receive too many open
ports!
for example I scan the mail relay and although just
port 25 is open it report lots of more open ports!
this is the nmap scan I issued:

nmap -sT -vv -P0 -O -p1-1024 200.61.44.48/28 -oA
cpsa.txt   

( I changed the ip's here...)

and the result for the mail relay for example are:


nteresting ports on mail.cpsa.com (200.61.44.50):
PORT     STATE    SERVICE
1/tcp    open     tcpmux
2/tcp    open     compressnet
3/tcp    open     compressnet
4/tcp    open     unknown
5/tcp    open     rje
6/tcp    open     unknown
7/tcp    open     echo
8/tcp    filtered unknown
9/tcp    open     discard
10/tcp   open     unknown
11/tcp   open     systat
12/tcp   open     unknown
13/tcp   open     daytime
14/tcp   open     unknown
15/tcp   open     netstat
16/tcp   open     unknown
17/tcp   open     qotd
18/tcp   filtered msp
19/tcp   open     chargen
20/tcp   open     ftp-data
21/tcp   open     ftp
22/tcp   open     ssh
23/tcp   open     telnet
24/tcp   open     priv-mail
25/tcp   open     smtp
26/tcp   open     unknown
27/tcp   open     nsw-fe
28/tcp   open     unknown
29/tcp   open     msg-icp
30/tcp   open     unknown
31/tcp   open     msg-auth
32/tcp   open     unknown
33/tcp   open     dsp
34/tcp   open     unknown

this continues up to port 1024..

any ideas how to eliminate so many false positives?

thanks a lot,

Juan
