similar to: [Bridge] i need help for bridge configuration

Hi there, I'm trying to set up a man-in-the-middle scenario within a VMWare Workstation team, using brctl. What I want is the following: PC1 eth0 >---LAN-segment-1---< eth0 PCMITM eth1 >---LAN-segment-2---< eth0 PC2 Now I did the following on PCMITM (PC man in the middle): ifconfig eth0 down ifconfig eth1 down brctl addbr lnxbr0 brctl addif lnxbr0 eth0 brctl addif lnxbr0 eth1

Hello all, First thanks to all for helping me. I have an issue to bring up bridging isis packets using BRCTL. As i am quite a newbie, maybe this is not possible or maybe I forget to load modules so that the bridging I am trying to put in place work properly. Here is the configuration I used: I1 ------ eth1 (physical interface of my linux machine) ----------- BRIDGE ----------- n1-eth0 (tuntap

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. Usage count =3D 2 The brctl user-level command is blocked. Could you explain me what could likely be the cause of this error?

Hello all, i would like to build a setup to generate VLAN frames (respecting the IEEE 802.1Q standard) for testing purpose. How to configure a Linux bridge for it to become a VLAN switch? Is it possible? What user tool to use for that? brctl? Regards, Louis

dear all: I try to configure a bridge in my embedded linux.

I've setup several bridges before using the code. Never had any problems. Recently I set Mandrake 10.0 up on a rackmount, with a builtin NIC and a 4 port ethernet card. Initially, I plugged 2 links

I've got a 2.6.8 kernel with bridging enabled as a module, two nics (LNE100TX and RTL8139) and i've run the following commands with no errors modprobe -v bridge brctl addbr br0 brctl addif br0 eth0 brctl addif br0 eth1 both interfaces have 0.0.0.0 as their addresses and brctl showmacs br0 shows the macs for both internal cards. However, bridging doesn't seem to be working at all.

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 >> >>

I tested a few setting (bridging as module, bridging compiled within Kernel...), but nothing matched. So I decided to install 9.1 and test again. And wow, it worked with only a few command lines:

Hi, I have a PPPoE server running on a linux box that accepts multiple PPPoE sessions from clients. I'd like to bridge each of the sessions together so that it looks like just one interface. Below is a diagram: br0 | ------------------------------- | | | | ppp0 ppp1 eth3 ppp3 I've read that anything can be bridge as long as MTU is the same.

Hello, I'm having a problem getting two (working) NICs enslaved to a bridge to both work in the bridge. The setup is just for testing and looks like this: (NETWORK)-------|bridge|---------|test PC| I'm building a bridge from an old Dell Optiplex GX1 desktop.

Julian, I did not understand what you meant by this paragraph. "Now, for the twist. For development and testing, I assigned an ip address and gateway to the bridge. I need to be able for a "non-it" person to install this box without having to set it up at all , so it cannot have an ip address assigned, as it *may* be in use somewhere else on the lan or router." Did your

Hello, I?m using the Linux Bridge on an Atmel Arm9 Plattform with the kernel 2.6.11rc3. The configuration is the following: LAN<--Arm9(Ethernet)--Bridge--Arm9(USB-Device)-->Notebook (USB-Host) or LAN<--Arm9(Ethernet)--Bridge--Arm9(USB-Host)-->Notebook (USB-Host) (with a Trust USB2.0 Host to Host cable) When I try to ping my Notebook from LAN and reverse, everything seems to be

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 than 2.6.11-rc2-bk9 yet. 2.6.8.1-bk2 still works

Hi, I am a beginner of bridge. I have a problem of using Fedora Core 2 to make a simple bridge. Here is my setup: The bridge computer is installed with Fedore Core 2 (with the SE Linux patch). As I know that kernel 2.6.5 is already support bridging by default, so I didn't recompile the kernel. Then I installed bridge-utils-0.9.6-1.i386. And no additional configuration is made. After
