Here is the proposed revision to the bridge utilities interface to the kernel. The driving force is that the existing interface can't easily be converted to 32/64 bit compat. Right now, the bridge-utils (brctl) tries to handle 32bit command on 64 bit kernel, but the code is limited to sparc and wrong. Here is what I am thinking. get version - not needed? get bridges -

So, I'm setting up my first bridge, and I'm running into an interesting issue. I have a 4 port NIC (formerly 4 seperate /29 and /28 LANs) and an onboard NIC (to my ISP). I've setup the bridge using the script included at the bottom of this email (modified from Gentoo for Aurora). When the WET11 (the WET11 is a simple ethernet to wireless bridge) is unplugged, the bridge works

Adding an STP state seems like a bad idea. Aren't br->stp_enabled and (dev->flags & IFF_UP) sufficient to determine whether check_link() should reenable a port? > -----Original Message----- > From: bridge-bounces@lists.osdl.org > [mailto:bridge-bounces@lists.osdl.org] On Behalf Of Mark Ruijter > Sent: Tuesday, July 20, 2004 7:25 AM > To: Stephen Hemminger > Cc:

Hello, I am a student considering participating in Google Summer of Code program. I came across Stephen Hemminger's idea of implementing a RSTP posted on http://developer.osdl.org/dev/soc/ and found it interesting. In attachment there's my proposal, which I just submitted to google. Please share your comments. -- tadeusz andrzej kad?ubowski -------------- next part --------------

Hi, Is there any particular reason why the same physical port cannot be added to multiple bridges? Is it because of STP? If I am not using STP - can I change the code to have the same physical port in 2 VLANs? Is that a safe change? Thanks, Abhijit

Hi, we're running the standard linux bridge setup (redundant bridge) for 5 years now. So first of all, thanks to everyone involved for implementing the bridging feature in Linux. Now I'm trying to bridge hosts connected to VLAN'ed Cisco switches using linux bridge. I'm testing the following setup (Kernel 2.6.19, bridge-utils 1.2 on both bridges)

<I apologize if this arrives twice... I sent it first from an non-subscribed address, don't know if that'll get to the list or not --JJ> Hi folks, I have an implementation question regarding bridging on a linux box between a catalyst trunk port and a cisco 26something w/802.1q subinterfaces. So right now, there's no vlan trunking going on on the link my bridging firewall sits

I'm sorry to bother you but I'm stuck I can not make a bridge work for me. My current configuration is: eth0 Link encap:Ethernet Hardware Adresse 00:1d:7d:d1:06:bd inet Adresse:192.168.1.1 Bcast:192.168.1.255 Maske:255.255.255.0 inet6-Adresse: fe80::21d:7dff:fed1:6bd/64 G?ltigkeitsbereich:V according to all what I could find in the net. The following should

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

Pavel, you may be interested in my work on Cisco HDLC bridging: http://marc.theaimsgroup.com/?l=linux-netdev&m=108802311131855&w=2 I have used it with the bridge driver (in 2.4) without any problems (yet ;)), and I am sure Krzysztof Halasa, the HDLC maintainer, would be thrilled if you managed to port it to a recent version of the kernel and make it a compile-time option. Oh, it also

Hi, What is the easiest way to bridge between two user-space processes that talk directly to Ethernet interfaces? I have two applications that write/read Ethernet frames to/from Linux Ethernet ports (e.g. eth0). The applications can successfully talk to each other when they run on two machines connected over Ethernet. I would like to be able to test them on a single machine without employing

Scratch that last comment. The kernel code I have now is identical to what I posted.

While using the linux bridge module in 2.6.10, the kernel seems to munge the source IP address of broadcast UDP packets if they come from "0.0.0.1", and sticks on an address of the linux host. I humbly submit that re-writing the source address of packets is not proper behavior for a bridge, even if those source addresses are not traditionally valid. Sure, 0.0.0.1 isn't a valid

This patch adds basic Virtual Ethernet Port Aggregator (VEPA) capabilities to the Linux Ethernet bridging utilities. The patch provides functionality that depends on the Linux kernel patch 'net/bridge: add basic VEPA support'. This patch relies on the patch 'bridge-utils: fix sysfs path for setting bridge configuration parameters'. A Virtual Ethernet Port Aggregator (VEPA) is

Hi! Jens Seidel reported a bug to Debian about a wrong message on brctl, you can see it at http://bugs.debian.org/383938, it is kind of the continuation of the ENODEV bug #348617 that was already patched by Stephen on the git. I have applied the same solution that Stephen applied for the first one, follows the patch against git plus a minor exclamation mark modification I did so that all ENODEV

Hi I intent to use brctl to bridge two devices on linux box. One is eth0, the other is USB net which is recognized as usb0 by linux box. Then I run following command # ifconfig eth0 down # ifconfig usb0 down # brctt addbr ipbr # brctl addif ipbr eth0 # brctl addif ipbr usb0 # ifconfig eth0 up # ifconfig eth0 0.0.0.0 # ifconfig usb0 up # ifconfig usb0 0.0.0.0 # ifconfig ipv6 up

Hello! "brctl stp br0" would crash brctl provided that br0 is a bridge. This is caused by incorrect number of arguments in the commands table. "stp" needs at least 2 arguments after "stp". The patch against version 1.0.4 is attached. -- Regards, Pavel Roskin -------------- next part -------------- --- brctl/brctl_cmd.c +++ brctl/brctl_cmd.c @@ -394,7 +394,7 @@
