Hello, I'd like to assign an IP to a vlan interface using DHCP (or to put it another way, 2 dynamic IP adresses on the same MAC). However, when using 'dhclient -cf ./dhclient.conf eth0.5', dhclient tries to broadcast a DHCP request, but nothing comes out of the wire - hence he doesn't get any offer. Actually iptables' OUTPUT doesn't see any packet going out. I tried with set_flag 1 but that didn't help. I also tried to specify explicitely the dhcp server, in case the broadcasting was the issue, but that doesn't change anything either. The DHCP server itself does support multiple IPs on a single MAC adress, by setting dhcp-client-identifier in dhclient.conf (I validated this by getting several leases using different identifiers on the same non-vlan interface). Shouldn't it work? Thanks :) Background: ~~~~~~~~~~~ I want to reproduce this demo tikiwiki setup: http://tikiwiki.org/tiki-read_article.php?articleId=130 but using VServer (linux-vserver.org) instead of proprietary VMWare :) So I'd like to start a vserver on a laptop machine, and attribute a second IP to that vserver via DHCP, on the default (unique) interface. The old version of VServer tools did support this out of the box: http://www.solucorp.qc.ca/changes.hc?projet=vserver&version=0.40#Using%20DHCP%20on%20vservers (the new one doesn't) The code (ftp://ftp.solucorp.qc.ca/pub/vserver/vserver-0.40.src.tar.gz) apparently creates a vlan eth0.x interface and starts dhclient on it. Workaround: I managed to assign 2 IPs via DHCP on 2 different MACs using the Candela macvlan patch, but I'd like to do it without - after all, the vservers guys did it once and I'd like to know how! I'd also like to publish this tikiwiki demo under the form of a chroot-able tarball, which wouldn't require any kernel patching (nor vserver, nor macvlan). Any clue? :) -- Sylvain
