You will find that you most likely have an apache web server running on your server. It is uses port 80.
If your not using apache then you can disable it. IF you don't have it, you can use 'lsof' to find what is using it. You can get lsof from here:

Hi ??

cat /etc/services | grep 80
http 80/tcp www # World Wide Web HTTP
http 80/udp www # World Wide Web HTTP

Hope it helps,

Robert-Jan.

hi,

see if ps -ef | grep apache or httpd helps.

if not download lsof as pointed already.


another option is netstat.

netstat -ap.

A specific way to use lsof to find this out:
lsof -n|grep TCP|grep ":80 "

netstat -a | grep 80 | grep LISTEN . It is probably a web server that is using the port.

[Ron Cornwell]

netstat -an | grep 80 | grep LISTEN . It is probably a web server that is using the port.
