We recently moved our fog server to a new machine, just moved the disk. The fog server was capturing tranmsit data on eth0 but the new machine is using eth1. I have tried editing the appropriate fog settings and the /fog/status/bandwidth.php. To no avail. What am I missing.

Thanks in advance.

I had a very similar problem, and to troubleshoot I setup my FOG server by itself. What I mean I set it up as a DHCP server connected to a small switch. No problems at that point. If you are just starting I recommend you start here first.
