Port 80 listen without WebServer?


Hi,

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?

Thanks

try

#netstat -pal

Gives you a list of active ports and the services that are listening on them.

Also, run

#tcpdump dst port 80

This will list any activity on port 80 of your system.

please post the entire output of nessus wrt the port 80 Security Note.

also, telnet to port 80 from another system and let us know the output.

You can try

#telnet <ip> 80

When the service responds,

get /

when telnet waits for a response.

OR, try connecting from a browser.
