For info, please visit http://www.isc.org/sw/dhcp/ Can't get interface flags for eth0foo: No such device For some reason it assumes «eth0foo» is a device of its own, which is not the case (doesn't show up as a separate interface in /proc/net/dev nor in the output of «ip a s»). It fails like this even when I ask it to listen on another interface which doesn't have labeled addresses, as long as a labeled address exist on a (unrelated) interface. Regards Tore Anderson
severity 379138 normal thanks Patient: "Doctor, it hurts when I do this" Doctor: "Well don't do that then" category. For what it's worth, if I add an IP address to eth0 with a label of eth0foo, ifconfig also has a hard time dealing with the situation. Try it and see. I suspect iproute is letting us doing things with the networking that older tools and methods of querying can't deal with. I'll try to send this upstream, but I don't know how much success I'll have. regards Andrew

* Andrew Pollock Well, ifconfig has been deprecated for years in favour of iproute2, precisely because it can't deal with lots of functionality modern Linux kernels provide. Developement on net-tools ceased in April 2001! So that's not really a good excuse for the dhcp3 suite to failing to work in what has been a perfectly valid setup for many years, IMHO. Regards
