I have 2 systems, both with the same version of CentOS installed. Both have identical versions of apache running and identical httpd.conf files. From a third system, if I point my browser at system 1, I can connect to it with no problem. But if I point my browser at system 2, I cannot connect. There is nothing logged anywhere that I can find on system 2 - not in the apache error log or access log, or the audit log, or anywhere. I tried disabling selinux, but that did not help. I can ping and ssh into system 2, so I know I have a route to it. It's like the request never reaches the server.

Anyone have any ideas as to what could be causing this or what I could check to help me diagnose the problem?

Hi Larry,

If you use netstat can you see if the service is listening on port 80 or 443?
