I have a RedHat 9.0 box which configures it's network card via DHCP from a firewall. This works great, but I need the system to default to a "link-local" (169.???.???.???) address if DHCP fails. Then if "link-local" fails, then set address to default to a static address (like 192.168.1.1).
Anybody ever try this on a IPv4 network?
For the 169.x.x.x behavior you can use tools designed to work toward this effort: http://www.zeroconf.org specifically "zcip". There are other tools to configure your network differently based on nearby hosts. It depends on what your definition of what you mean "169.x.x.x" failing. It's difficult to detect if _anyone_ is participating on a subnet or not. But, you might want to configure in a certain way depending on whether you're at home, work, or a wildcard case.

I'd just like to note that Mandrake as of 9.1 (the previous version) has supported this behavior out of the box. :-) Connect two mandrake boxes to a switch without a dhcp server and they'll find each other and let you network together. It will also do the same with Macs running OS X.
