Do you have some udev rules defined which are picked up on the second time that the ifplugd brings up the card, but not the first? Any suggestions where to start? Or just disable ifplugd? Have you tried configuring static IP addresses, broadcast and gateways for each card using the /etc/cong.d/net file? You can still set dhcp as a fall back if you want, although I am not sure it is necessary for a server in a static LAN. The file /usr/share/doc/netifrc-0.2.2/net.example.bz2 provides suggestions for different set ups. -- Regards, Mick signature.asc Description: This is a digitally signed message part.
