With recent 2.6 kernels, the command brctl delbr br0 hangs during shutdown, and the kernel prints this message again and again: unregister_netdevice: waiting for br0 to become free. Usage count = 1 I was able to reproduce this problem with several kernels between (and including) 2.6.9-rc1 and 2.6.11-rc2-bk9. I haven't tried later versions...

When i want to delete my test bridge, using: ifconfig eth0 down ifconfig eth1 down ifconfig br0 down brctl delif br0 eth0 brctl delif br0 eth1 brctl delbr br0 i get this error message from the kernel on the console: unregister_netdevice: waiting for br0 to become free.

Hi, "brctl" returns 0 when trying to delete non-existent bridge. If it returns 0, scripting will be an headache. It should return different than 0. # brctl delbr geek bridge geek doesn't exist; can't delete it # echo $? 0 Thanks. -- Aycan iRiCAN Core Computer Security Group http://www.core.gen.tr

So Working on CEntOS 5 I am trying to sett up Xen with 2 bridges, one that connects dom0 and most of the domU to the physical card and the out to the network. Got that figured out no problem, now i want to have a second bridge that runs a local network for all the doms that doesn''t connect to the network. With code I have found used in multiple places I can easily get 2 bridges, and

I have been managing because I can restore connectivity be deleting the bridge mpower@dodtsair:~$ sudo ifdown eth0 mpower@dodtsair:~$ sudo brctl delbr eth0 But that means any domUs will not have connectivity. I have not had any till now so it wasn''t much of an issues. But thanks to your help now I have XP running. Ultimately I would really like you to show me the documentation that tells me how to fix this. I am pretty sure it e...

Hi all, I''m searching for a tutorial how to setup multiple network cards with xen network bridge setup in debian lenny. My problem is, bridges seams only to work if i put an ip adress in dom0 to them.

Hello, I how an embedded processor that needs to act as a bridge between a wireless and wired network. I have managed to bring up the bridge fine. I can also bring up the bridge with a static ip address. However I can not figure out how to bring up the bridge with a dynamic ip address. Is it possible to for a bridge to get a dynamically assigned ip address? Oliver

Currently my ethernet bridge has 2 intel 100mps NIC's that are both part of a bridge. ( I followed the sample setup on the bridge.sf.net page.) In addition to this I would like to access the internet from within the ethernet bridge and when using the sample instructions I have no gateway setup and no default route (0.0.0.0). I know this data has to be attached to the bridge device and not to
