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). 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 ____________________________________________________________________________________ Catch up on fall's hot new shows on Yahoo!
