Really strange network issue... please help (SOLVED)
Here is my setup:
1 physical server with VMWare ESXi on it
2 Virtual servers on the ESXi Server
1 physical NIC to the box
I have always been able to get to serverA and serverB on my ESXi server; however, sometime today I started experiencing connectivity issues to serverB. I restarted the server and now I can't get to serverB at all; however, I can still get to the ESXi server and serverA on the ESXi server. Because of that, I know my physical routing is still fine.
While I cannot get to serverB, everyone else in the world can (which I confirmed by VPNing into work and hitting the site, and I checked with a brother to see if he could hit it too, which he could).
Well, that led me to believe that the problem is on serverB itself, such as a firewall setting or something. I disabled the firewall, flushed the iptables, made sure that the /etc/hosts.deny file didn't have an entry in it for my current IP address/network, and disabled xinetd. I still cannot get to this box at all (http, ssh, etc).
Where else should I look? I can't think of anything else that may be blocking it. I don't have apparmor enabled (openSuSe server), and I just am at a loss as to where to look.
Come to think of it, serverA can reach serverB, so it isn't a problem with my network, but just my physical IP. I disabled the firewall and xinetd and even rebooted the box with those off, and I am still having the issue....... :confused:
Any help would be greatly appreciated.
