similar to: [Bridge] tracking packets on bridge

Hi! As noted by Chris Rankin on a mail to netfilter-devel and to the linux-kernel mailing list (subject: 2.6.12: connection tracking broken?), there is a problem with the connection tracking of iptables when one of the interfaces is a bridge. On my tests here I have setup a connection between two machines using a real interface (eth0) and then the same setup using a bridge interface (br0) to

I have a bridge br0, it enslaves two NICs: eth0 and eth1. By using "cat /proc/net/dev ", i can see the Rx/Tx packets and bytes through each interface. just like this: [* time tick 1 *] Inter-| Receive | Transmit face |bytes packets errs drop fifo frame compressed multicast|bytes packets errs drop fifo colls carrier compressed

Ahoy, I've encountered some confusing semantics with using PACKET(7) sockets on bridge-enslaved interfaces. Specifically, if my socket accepts all types of frame (bind() to ETH_P_ALL) then it gets all packets; but if it accepts any specific type (e.g. ETH_P_IP), then it receives no packets at all. That is how it's coded in net/core/dev.c's netif_receive_skb(). First ETH_P_ALL

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. Using kernel-2.6.9-gentoo-r4, with bridging and ebtables compiled into the kernel; the two PCI NICs are Intel, and the e100

What is the maximum number of devices that can be enslaved in a bridge interface? I have tried enslaving 512 devices. Although the brctl tool did not complain while adding them, when I use brctl show command it only shows 255. Thanks

Hi all Assume that you have a linux bridge with two interfaces eth0 and eth1 enslaved to this bridge What is the difference between sniffing the bridge and sniffing its interfaces? tcpdump -i br0 vs tcpdump -i eth0 Thanks MiniME -------------- next part -------------- An HTML attachment was scrubbed...

Hi, ppl, I am using kernel 2.4.25 and having this peculiar problem on my ixp425. When i have 2 ethernet ports of the board connected to the same linksys switch running STP. ixp0 and ixp1 are the name of my ethernet ports enslaved to the same bridge( br0)and my PC is also connected to the switch. IXP425 -br0 (192.168.2.1) |_ixp0|--- |

I can think of several potential differences. ?You may miss any bridge specific traffic (STP, LLDP) using the interfaces generated by the bridge itself. If you have vlan tagged sub interfaces you might also miss that traffic if you were snooping a particular interface. Obviously you will miss any on-wire broadcast traffic specific to the layer1 connection a particular interface was connected to

Hi bridge list: Bart de Schuymer suggested that this question might be better placed on this list rather than in the ebtables area. So here it is : ================================================================= Hi listers: I am a relative Penquin Newcomer, and I am (therefore?) encountering problems trying to setup a simple bridge/firewall between two vlans sharing portions of the same

All I have the following setup: 4 VLAN interfaces enslaved in a bridge interface. All VLAN interfaces don't have IP address. The bridge interface has 192.168.1.1/24. Now, when I try to ping from one of the VLAN interfaces, through a host connected to a VLAN switch, while dumping the traffic, the following happens: - Host sends ARP who-has broadcast to the VLAN interface (tagged correctly,

Hi everybody, Just have myself added into the maillist. I have a few linux boxes with Kernel 2.6.9. Each box has 2 ethernet interfaces, one 3COM, one Intel. I connected one with Power Line Modem, and one with Wifi Modem. They form a nice network with bridge. I have a few questions here. Suppose I have two path from box A to box D, which path will packets go through? If I want to monitor the

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 that make any difference in overall transfer rate of the bridge? I was thinking it

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

Hi there :) I would like to submit a use case we are here: our company make network probes with 1 administravia interface and the rest in promiscuous mode to listen traffic. I've made virtualized server with Qemu. All Qemu instances (with 2 tap) listen on: br0 (admin int) br1 (receive traffic) The need is each tap on br1 must listen *all* traffic (unicast, multicast...). For this, I sets

I am battling an issue with use of bridging with xen. For some yet undetermined reason supposedly relating to stp, they assign a mac address of fe:ff:ff:ff:ff:ff to the bridge. Was hoping someone here may be able to elaborate on that. If I enslave a bridge to an ethernet, and than restart that network interface, should the bridge operation behave the same after the ip interface is restarted?

Hello, I am working on Network-Simulation (VNUML). Our simulator uses linux bridgi= ng to connect the UMLs. So there is one problem: The example is the following: There are two hosts simulating one big net. The two hosts have connection over the external nets Net3 and Net6 (see htt= p://www.uni-koblenz.de/~timbub/verteilteSim3.GIF), but in fact there is onl= y one physical connection between the
