Connection Reset

So strange… Installed… centos 7… I’ve opened the firewall… checked the services… I still get a reset… full tcp handshake… I browse to “http://my-server-ip/opennms

Thoughts?

Solved this… my bad… I do have opennms behind a firewall… I hunted down my misconfiguration… once I created the rule properly… all is well.

The way I discovered this… I moved the opennms server out from behind the firewall… and it worked like a champ… moved it back… did not work… realized it HAD to be my darn firewall. I’d been staring at it for so long somehow i missed the denies and that it was sending a rst back to both devices.
