I have a RedHat/Conectiva 8 and i runned nessus and i received the follow message:

Security Note: Port: www-http ( tcp/80)

But i don't a web server running. I runned the chkrootkit and it doesn't find nothing. The same to Clamav, that doesn't find nothing. The netstat -anp doesn't show port 80 too. But when i run the nmap from other computer, the port 80 is listening.

Anyone can help me?
