Connection was reset - Apache

Question

I have a server in which I can ssh using the live IP. The server is connected through a DMZ port. whenever I try to access the web server in the server I get Connection was reset.

My SeLinux is turned off. I tried switching off IPTABLES. I changed the httpd to listen to its LAN IP assigned to etho

Listen 192.168.0.254:80

Nothing worked.

This is what IPTABLES -L gives me

I found the following using

strace -f -o apache.trace /usr/sbin/httpd

Answer 1

(98)Address already in use: make_sock: could not bind to address 0.0.0.0:80 no listening sockets available, shutting down

This means something else is already listening on port 80 and your server can not bind to that port. It is already in use. You probably have more than one "Listen" statement that uses port 80, or another application is already on that port.

As root, type:

netstat -aeenp | egrep "User|:80"

This should tell you what is listening on that port.
