What mean nmap


i run nmap from one my server to another ( another IP) and i give this:
Starting nmap 3.93 ( http://www.insecure.org/nmap/ ) at 2006-10-30 10:02 EET
Initiating SYN Stealth Scan against ip
(ip) [1668 ports] at 10:02
Discovered open port 80/tcp on ip
Discovered open port 3389/tcp on ip
Discovered open port 53/tcp on ip
Discovered open port 3306/tcp on ip
Discovered open port 3128/tcp on ip
Discovered open port 110/tcp on ip
Discovered open port 139/tcp on ip
Discovered open port 587/tcp on ip
Discovered open port 221/tcp on ip
Discovered open port 993/tcp on ip
Discovered open port 445/tcp on ip
Discovered open port 995/tcp on ip
Discovered open port 1984/tcp on ip
Discovered open port 143/tcp on ip
The SYN Stealth Scan took 16.69s to scan 1668 total ports.
For OSScan assuming port 53 is open, 1 is closed, and neither are firewalled
Host ip (ip) appears to be up ... good.
Interesting ports on ip (ip):
(The 1653 ports scanned but not shown below are in state: closed)
PORT STATE SERVICE
25/tcp filtered smtp
53/tcp open domain
80/tcp open http
110/tcp open pop3
139/tcp open netbios-ssn
143/tcp open imap
221/tcp open fln-spx
445/tcp open microsoft-ds
587/tcp open submission
993/tcp open imaps
995/tcp open pop3s
1984/tcp open bigbrother
3128/tcp open squid-http
3306/tcp open mysql
3389/tcp open ms-term-serv
Device type: general purpose
Running: FreeBSD 5.X
OS details: FreeBSD 5.3-STABLE
TCP Sequence Prediction: Class=truly random
Difficulty=9999999 (Good luck!)
IPID Sequence Generation: Incremental

Nmap finished: 1 IP address (1 host up) scanned in 19.328 seconds
Raw packets sent: 1873 (75.5KB) | Rcvd: 1714 (78.9KB)


What is this Discovered open port and later open port?
thanx and sorry for my english

Which one? As far as I can see they're all listed with their name (which
doesn't necessarily mean that the ports are actually being used by those,
that's just the "common culprits"). Have a look at the output of lsof -i
on the target machine and try to match the ports you see to the names in
nmaps list.


Cheers,
Tink

That would depend on which version of which application is listening.
We most certainly will NOT give you information on how to break into
other peoples machines. Just use google, search for exploit :P
