You're not looking hard enough https://www.google.com/search?q=ubuntu+bridge+without+ip+address http://wiki.1tux.org/wiki/Ubuntu/Bridge > In "interfaces", I have something like this > auto br0 > iface br0 inet manual > pre-up echo "Starting $IFACE" > pre-up ip addr flush dev $IFACE > pre-up ip link set $IFACE down > post-down ip link set $IFACE down > > How do I create the bridge? > in /etc/rc.local I execute brctl addbr br0 > > There is nothing wrong with this , right? Yes, there is. On trusty the error message is clearer: Cannot find device "br0" Basically ubuntu does not know "br2" is a bridge. You need (at the very least) "bridge_ports none". My example if the wiki uses dummy interface for the bridge. Here's another example (again, on trusty): (snippet from /etc/network/interface) auto fancy-if-name iface fancy-if-name inet static bridge_ports none address 0.0.0.0 netmask 0.0.0.0 # brctl show fancy-if-name bridge name bridge id STP enabled interfaces fancy-if-name 8000.000000000000 no # ifconfig fancy-if-name fancy-if-name Link encap:Ethernet HWaddr 02:aa:fd:37:bb:a5 inet6 addr: fe80::aa:fdff:fe37:bba5/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:23 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 B) TX bytes:3809 (3.8 KB) > note: I will allow access to the box anybody whose email says @canonical. While you are entitled to give access to whoever you want, that note in my oppinion is a very selfish one. You're basically saying: - you want support from someone in canonical - you don't want to pay for the support - you don't trust anyone else in the list The open source community (including lxc) does not only consist of paid developers that work in a company. More often, a quick and useful answer will come from a fellow user. -- Fajar _______________________________________________ lxc-users mailing list [email protected] http://lists.linuxcontainers.org/listinfo/lxc-users
