I'm trying to setup a network bridge in Ubuntu between my ethernet card and a usb-ethernet adapter.
When I boot Ubuntu from a USB flash (a real install with GRUB, not Ubuntu-Live) I get the line "Waiting for network configuration...", and later "Waiting 60 more seconds for network configuration...", and later "Booting without full network configuration". The two ethernet ports eth0 and eth1 are not bridged, which is what I want them to be.
Here are the contents of
auto lo iface lo inet loopback auto eth0 iface eth0 inet manual auto eth1 iface eth1 inet manual auto br0 iface br0 inet static bridge_ports eth0 eth1 address 192.168.100.91 gateway 192.168.100.1 netmask 255.255.255.0
