NMAP - strange output :S

hi everyone;

I have a problem with this command, It is showing a strange output where all ports are closed NMAP - strange output :S

[root@server root]# nmap -p 1-65535 localhost

Starting nmap V. 3.00 ( www.insecure.org/nmap/ )
All 65535 scanned ports on server (127.0.0.1) are: closed

Nmap run completed -- 1 IP address (1 host up) scanned in 52 seconds



As you can see this is impossible cause' I'm connected to ssh and apache is running to...

If I run "nmap" to look in a particular port as 80, it shows:

[root@server root]# nmap -p 80 localhost

Starting nmap V. 3.00 ( www.insecure.org/nmap/ )
Interesting ports on server (127.0.0.1):
Port State Service
Unable to find nmap-services! Resorting to /etc/services
80/tcp open http

Nmap run completed -- 1 IP address (1 host up) scanned in 1 second


This sistem is running "Fedora Core release 2 (Tettnang)" with all last updates installed. I run rkhunter to see if binary is corrupted, but its not...

Any idea?

Thanks for your help;

Luciano Tourreilles.
