Emulab FAQ: Testbed Operations: Problem with IP addresses not being configured.

First thing to do is look in /var/emulab/boot on the broken nodes and see if the node is getting the right stuff from the DB.

What is in /var/emulab/boot/tmcc/ifconfig ? ... If it's empty, then the DB is not setup properly and we need to look further upstream.

The IFACE can actually be null; its really an override used with virtual nodes.

Anyway, the MAC address is more important. Is that MAC address really on the node, and is that interface "active" to the switch (did the switch port get activated?)

And of course, I assume you looked at the console log for obvious errors!
