Hi, I'm using linux 2.6.21.5 and our kernel is freeze. The problem is, if I create a Software bridge using $brctl command. and add two interfaces say, eth0.0 and eth0.1 using $brctl addbr br-lan $brctl addif br-lan eth0.0 $brctl addif br-lan eth0.1 and when i send traffic from a host connected to one port to host connected at other end, soon all the memory is dried up and and kernel crashes, then oom-kille...

Santiago, I appreciate your offer. I'm not really a kernel hacker, however I do know C and I would be willing to try if you point me in the right direction. Here is my first attempt using Debian running on an UltraSPARC: debian{root}:/root<512>strace -f -F -v brctl addbr br0 execve("/usr/sbin/brctl", ["brctl", "addbr", "br0"], [/* 16 vars */]) = 0 debian{root}:/root<513>strace -f -F -v brctl addif br0 eth1 execve("/usr/sbin/brctl", ["brctl", "addif", "br0", "eth1"]...

Stephen Hemminger, Yes,I use V2.4.17. Which patch can I use? Or can you tell me the reason,so that i can modify my Kernel.I use this kernel at the embeded system. >Haisen.Zhang wrote: > >>shemminger? >> >> I have a problem with brctl application,following is my operations: >> >> vconfig add eth0 3 >> >> brctl addbr br0 >> >> brctl addbr br1 >> >> brctl addif br0 eth0.3 >> >> brctl delif br0 eth0.3 >> >> brctl addif br1 eth0.3 >> >>? brctl...

...net, and clients are able to talk to each other. When the WET11 is plugged in is when things start acting up. Every client (including those behind the WET11) are able to connect out to the internet, but clients cannot talk to each other. If Client A(port 1) tries to connect to Client B(port 2), `brctl showmacs br100` shows that Client B moved to port 4(port 4 is where the WET11 is plugged in. If I change the WET11 port, the port Client B moves to is also changed), and the router can no longer ping Client B. [root@deadbeef root]# brctl showmacs br100 port no mac addr is local?...

...n I have works intermittently. vtun seems to work reliably - am using the -p (persist) option to force reconnect on disconnect. However I have the following problems: 1) On system startup vtun connects to the server correctly, but the bridge does not come up. (my vtund.conf attached) brctl show - shows the "brookf" bridge, but 'Interfaces' declares: "can't get port info: Function not implemented" Restarting vtun with /etc/init.d/vtun restart brings the bridge up correctly. Why is this? Currently I'm having to restart vtun on system startup t...

Hi there, I'm trying to set up a man-in-the-middle scenario within a VMWare Workstation team, using brctl.

Hello all, I'm trying to bridge the wlan0 and eth0 on an embedded system. I used the following commands to setup the bridge: ifconfig eth0 0.0.0.0 promiscuous ifconfig wlan0 0.0.0.0 promiscuous brctl addbr br0 brctl addif br0 eth0 brctl addif br0 wlan0 brctl sethello br0 1 brctl setmaxage br0 4 brctl setfd br0 4 ifconfig br0 up The eth0 is connected to a local network, and wlan0 is set to Ad-hoc mode with proper SSID. After the bridge is stablized, I use dhclient to assign an IP for br0. Then...

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

dear all: I try to configure a bridge in my embedded linux. I had fininshed these operations below: 1) configure kernel, select the option "802.1d bridge" 2) compile bridge-utils 3) issue these commands: ifconfig eth0 0.0.0.0 ifconfig eth1 0.0.0.0 brctl addbr vb brctl addif vb eth0 brctl addif vb eth1 ifconfig vb 192.168.110.24 up 4) cd /proc/sys/net/bridge for x in bridge-*; do echo 0 > $x; done 5) Then I connect PC0 to the eth0, and connect PC1 to eth1. The PC0 IP is 192.168.110.22, the PC1 IP is 192.168.110.60...

Hi wondering if anyone can help. I have two NICs on a debian sarge based system and current running as a bridge (br0) which consists of eth0 and eth1. Is it possible to add a virtual interface to the eth1 so I can also do NAT on the box as well? I have tried many times and keep coming up with errors. Kind Regards William Bohannan

Hi All, I am using Linux 2.6.15 kernel. I want to create 4094 bridge interface but I am able to see only 32 bridge interfaces with the help of "brctl show". I am able see other interfaces into /proc/net/dev but brctl is not showing more then 32. It is also not allowing any operations (add/del) over those interfaces. Is it correct behaviour or I have do some changes in some settings.? Could anybody please help me in this?? With Regards Ra...

I noticed that when I type brctl - it does insmod when the bridge module is not loaded. Where can I find the code (in the brctl or libbridge code) which does that? Thanks, Abhijit
