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...

The network-bridge script fails when setting a few sysctls which are only available if ebtables is present in the host kernel. Fix by ignoring the return value of the sysctl command.

Hello all, I would like to know if it is possible to have 2 bridge instances running - one for the internal network and the other for the external network. What I need to explain is that I need the internal bridge to go though the Linux Kernel and pass its packets to the external network bridge. I am also hopeful that the internal network bridge will not need a...

...wireless capability to my Gentoo-linux based firewall/router at home, so I bought a Netgear MA311 PCI and installed the hostap package. I load the hostap_pci module and the wlan0 interface comes up fine. I can detect the signal from a wireless enabled laptop. Now I'm thinking I'm going to bridge the wlan0 interface and the eth1 interface, and run the firewall with br0 as the internal interface. I compiled the kernel (2.4.23) with CONFIG_BRIDGE=m but when I modprobe bridge, I get this stuff: /lib/modules/2.4.23-ck1/kernel/net/bridge/bridge.o: unresolved symbol br_ioctl_hook /lib/modules/2....

Hiya, I would have expected this to show the channels in the bridge inside the anonymous function - it shows the bridge is empty though? var bridge = ari.Bridge(); bridge.create({ type: 'holding', name: event.application+" bridge"...

Hi, The attached patch fixes the setup of the bridge ports and the bridge itself. Changes: * move some functions to xen-network-common.sh, so both vif-bridge and network-bridge can use them. * add a new function to configure bridge ports and use it. * make sure arp requests, ipv6 autoconfiguration and ipv6 router solicitations are dis...

I have a bridge that has gigabit interfaces. The machine in question has the fun job of being a Bridge, Firewall and SMB server. Both of the Gigabit interfaces are connected to workstations directly via Xover cable (well MDI-X to be exact). My question is, if I enable jumbo frames on the gigabit interfaces will th...

...script works for both Xen 4.0 (xm) and Xen 4.1 (xm/xl). When I was first setting up Xen I was playing with VLAN tagging for separating test domains so I designed the vif-network script to handle tagging traffic on a port. In order to take advantage of tagging you must append the tag number to the bridge name in your guest domain configuration file separated by a period. i.e., vif = [ ''bridge=ovs0.3'' ] I hope this helps someone. Enjoy and good luck! /etc/xen/scripts/network-openvswitch: #!/bin/bash #============================================================================ #...

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....

The following series adds 2 new flags to bridge. One flag allows the user to control whether mac learning is performed on the interface or not. By default mac learning is on. The other flag allows the user to control whether unicast traffic is flooded (send without an fdb) to a given unicast port. Default is on. Changes since v4: - Implemen...

I have a Xen DomU configuration that was made in the days before libvirt and virt-install. In this configuration I have: vif = [ ''mac=00:16:3e:05:06:01, bridge=xenbr0'', ''mac=00:16:3e:05:06:0a, bridge=xenbr1'' ] and then in xend-config.sxp I define (network-script my-network-bridge) where my-network-bridge is in the scripts directory and looks like this: [root@fermigrid6 xen]# more scripts/my-network-bridge #!/bin/sh # start...

Hi Rahul, If you're certain that your problem isn't as Stephen suggested, you might want to have a look at this: --- (From http://ebtables.sourceforge.net/brnf-faq.html <http://ebtables.sourceforge.net/brnf-faq.html> ) How do I let vlan-tagged traffic go through a vlan bridge port and the other traffic through a non-vlan bridge port? Suppose eth0 and eth0.15 are ports of br0. Without countermeasures all traffic, including traffic vlan-tagged with tag 15, entering the physical device eth0 will go through the bridge port eth0. To make the 15-tagged traffic go through t...

Hello, Due to a recent change in the bridge code, we now need a way of knowing if a packet has been defragmented. The bridge code now checks on the packet size and drops packets that are too big for the output port. Defragmented packets will get refragmented later, so they shouldn't be dropped. I've been reading the defragmentation c...

Hi, all the descriptions of networking setups with VMs I`m seeing involve bridges. The only use I see for bridges is when I actually want to be able to send network traffic to multiple arbitrary interfaces connected to the bridge. I do neither need, nor want bridges when I want to keep the VMs separated, like when separating a VM in a DMZ from a VM in the LAN. The bridge act...

Hi, I've been using CentOS & Xen on a server that has 2 VM's configured. The default configuration includes one physical iface that is propagated (by a default bridge) to the VM's. Since I wanted to configure additional physical iface, define a new bridge and propagate it to the viface-s of the VM's, i configured the bridge/phys. iface and brought it up (here are configurations that I set up): -> eth3 DEVICE=eth3 BOOTPROTO=static HWADDR=D4:85:64:4B:...

Hi all, I have a bridging firewall running fine with kernel 2.4.31 (Slackware 10.1) and iptables 1.2.11 Yesterday I install the new kernel 2.6.14.3 and iptables 1.3.4 but the bridging firewall doesn't work anymore. Do I need to patch the kernel 2.6 as what I did it for kernel 2.4? Or what I have missed? Regards, ro0ot

A malicious actor behind one bridge port may spam the kernel with packets with a random source MAC address, each of which will create an FDB entry, each of which is a dynamic allocation in the kernel. There are roughly 2^48 different MAC addresses, further limited by the rhashtable they are stored in to 2^31. Each entry is of the ty...
