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 -

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 an IP address as I am hoping to

Hello, I want to add 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

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 disabled for the bridge ports and also for the

...l that make any difference in overall transfer rate of the bridge? I was thinking it might because even though the NIC is enslaved, it IS the device that the workstations communicate to. But also it might not because when applications talk to the network they're using BR(n) at 1500bytes.. can a bridging guru shed some light on this for me? -Thank you in advance Chris

A huge thank you to mario from the ''openvswitch on Xen 4.1'' post. I was having some trouble with using openvswitch with Xen 4.1 (I''m currently migrating from 4.0.1) until I saw his post and noticed that the xl.conf needed the full path to the networking script. Made this change and all is good now. Thank you. I would like to contribute what I have for using

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

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: - Implemented Stephen's suggestions. Changes since v2: -

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:

...: Stephen Hemminger Subject: Re: [Bridge] bridge is not forwarding the packet Hi Stephen, Thanks for your very prompt response! Actually my problem is not related to MAC address restrictions from wireless interface/driver. The problem lies mainly in multiple bridges for different vlans. Since bridging happens first, the packet ends up on wrong bridge and gets discarded form that bridge. If Vlan handling is done prior to bridge handling, my setup will work fine. There is also another thing which I did not understand. When we add an interface to vlan, the newly created interface's hard_head...

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 code and can't find an easy way of knowing if a

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 acts like a hub.

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

Hi, I had successfully setup my bridge (br0) but after few minutes the br0 interface seems not working. ifconfig eth0 0.0.0.0 ifconfig eth5 0.0.0.0 brctl addbr br0 brctl addif br0 eth0 brctl addif br0 eth5 brctl stp br0 on I check on my system's /var/log/syslog file. It shows something strange messages as below: - Jan 2 10:44:22 fw01 kernel: ipt_tcpmss_target: bad length (64 bytes)

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, r...

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 type struct net_bridge_fdb_entry, which is currently 128 bytes big.
