I'm hoping this is the right spot to put this.
I'm currently configuring a server with Packet Fence. Half-way through the initial configuration, something happened to kill my network connection. After checking the GUI network manager, I noticed one of the two Ethernet interfaces was missing.
I'm still rather new to Linux, so I'm not 100% sure what I should check or change. The distro the server is running is CentOS 6.3.
Any help would be much appreciated.
