apache bound to every ip port 80

You would need to edit /usr/local/apache/conf/httpd.conf starting with this

Code:

#
# Port: The port to which the standalone server listens. For
# ports < 1023, you will need httpd to be run as root initially.
#
Port 80

And it's also mentioned many other places, which will probably be modified by Cpanel at some point. Why not just bind this other program to another port, then change such a big part of your server?

 

And I'll ask a not-so-obvious question... could this be a web-app that's just not configured correctly?
