Thread: NICs do not get an IP address even though they are defined in /etc/network/interfaces

hi all!

it's pretty hard google issue because gives lot of noise results, i'm posting here.
using ubuntu 10.04.
not of nics don't ips assigned @ boot though defined in /etc/network/interfaces:

code:

auto lo iface lo inet loopback  auto eth0 iface eth0 inet manual         address 172.16.1.3         netmask 255.0.0.0     gateway 172.16.1.255  auto tap0 iface tap0 inet static         address 172.16.1.1         netmask 255.0.0.0     gateway 172.16.1.255         pre-up vde_tunctl -t $iface         post-up vde_switch -t $iface -s /tmp/vde-$iface \                 -d -g rhuser -m 664         post-down vde_tunctl -d $iface  auto br0 iface br0 inet static         address 172.16.1.2         netmask 255.0.0.0         gateway 172.16.1.255         bridge_ports eth0 tap0

note network-manager apt-get purged system , not in way.
here's output ifconfig:

code:

$ ifconfig br0       link encap:ethernet  hwaddr 78:e3:b5:90:88:df             inet addr:172.16.1.2  bcast:172.255.255.255  mask:255.0.0.0           inet6 addr: fe80::7ae3:b5ff:fe90:88df/64 scope:link           broadcast running multicast  mtu:1500  metric:1           rx packets:156 errors:0 dropped:0 overruns:0 frame:0           tx packets:17 errors:0 dropped:0 overruns:0 carrier:0           collisions:0 txqueuelen:0            rx bytes:36414 (36.4 kb)  tx bytes:3317 (3.3 kb)  eth0      link encap:ethernet  hwaddr 78:e3:b5:90:88:df             inet6 addr: fe80::7ae3:b5ff:fe90:88df/64 scope:link           broadcast running multicast  mtu:1500  metric:1           rx packets:156 errors:0 dropped:0 overruns:0 frame:0           tx packets:17 errors:0 dropped:0 overruns:0 carrier:0           collisions:0 txqueuelen:1000            rx bytes:38598 (38.5 kb)  tx bytes:3317 (3.3 kb)           interrupt:32 base address:0xe000   lo        link encap:local loopback             inet addr:127.0.0.1  mask:255.0.0.0           inet6 addr: ::1/128 scope:host           loopback running  mtu:16436  metric:1           rx packets:1408 errors:0 dropped:0 overruns:0 frame:0           tx packets:1408 errors:0 dropped:0 overruns:0 carrier:0           collisions:0 txqueuelen:0            rx bytes:113404 (113.4 kb)  tx bytes:113404 (113.4 kb)  tap0      link encap:ethernet  hwaddr c2:e3:c8:17:69:0f             inet6 addr: fe80::c0e3:c8ff:fe17:690f/64 scope:link           broadcast running multicast  mtu:1500  metric:1           rx packets:0 errors:0 dropped:0 overruns:0 frame:0           tx packets:0 errors:0 dropped:173 overruns:0 carrier:0           collisions:0 txqueuelen:500            rx bytes:0 (0.0 b)  tx bytes:0 (0.0 b)

note: br0 assigned ip reason.
also, if use ifconfig command assign ips temporarily, works fine. assignment @ boot issue.

there must simple i'm missing here. suggestions appreciated!

(in case you're wondering i'm going - i'm trying have configuration several virtual machines talking each other, host, , outside network. host not connected internet - it's on local network.)

your formatting of /etc/network/interfaces looks kind of quirky

wild guess.

stuff this

code:

            address 172.16.1.3          netmask 255.0.0.0      gateway 172.16.1.255

try changing

code:

         address 172.16.1.3  netmask 255.0.0.0  gateway 172.16.1.255

again, guess copy paste (if thats did)
has inserted hidden control characters , non blank spaces
