hi: my box use eth0 connect my pc. but I type command "./brctl showmacs br0", no mac addr display and the" brctl showmacs program" not exit,always exec # ./brctl show bridge name bridge id STP enabled interfaces br0 8000.000123456789 no eth0 hdlc0 # ./brctl showmacs br0

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

Hello, I have been using the bridging facilities provided by Linux (vanilla 2.6.7 SMP with UML skas host patch applied) to bridge a regular physical ethernet network (on interface eth0) with a virtual network (on interface tap0, cf uml_switch, http://user-mode-linux.sourceforge.net/networking.html). A couple of virtual machines (run using user-mode linux, a tool that enables you to run linux

I've been playing around with qemu and wanted to make the guest OS instance visible on my network. This meant getting bridging and tun/tap working. After getting things working by pasting command from the CentOS wiki article plus adding a few enhancements, I decided to capture the process in a shell script that would be suitable for a user in the sudoers file to fire off. Not sure why

Hi all, I''m having a hell of a time getting my IFB to work. I know I''ve done this before, so I''m missing something stupid. Can anybody tell me what it might be? Configs as follows: -------- #!/bin/sh modprobe ifb numifbs=1000 modprobe act_mirred modprobe 8021q brctl addbr br0 brctl setfd br0 0 brctl stp br0 off brctl addif br0 eth1 brctl addif br0 eth2 ifconfig eth1

Here is the scenario: I have one server with kernel 2.4.24 with a bridge br0 made of 2 interfaces, eth0 and tap0 (the last is an OpenVPN tunnel), and one remote computer connetting through tap0. If I assign a static IP to the remote computer, the bridge works perfecly (so I think the problem is not OpenVPN-related). If I start a DHCPd on the server and I configure the remote client to get the

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'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.

Hi, I'm trying to build a bridge using a 486DX2/66 with two 10 Mbit Ethernet NICs. The machine (tsushima) is running Debian stable and kernel 2.4.26. Previously I used it as a router, so I know the hardware (NICs) is working. The NICs are as follows: eth0: WD80x3 at 0x280, 00 00 C0 0A 2C 2F WD8003-old, IRQ 10, shared memory at 0xd0000-0xd1fff. eth16i.c: v0.35 01-Jul-1999 Mika Kuoppala

re can somebody tell me what am I doing wrong (at this late night hour), because vlan are not getting bridged at all. ifconfig eth0 0.0.0.0 up ifconfig eth1 0.0.0.0 up brctl addbr br0 brctl addif br0 eth0 brctl addif br0 eth1 ifconfig br0 up vconfig add br0 X vconfig add br0 Y X = vlan-ID (example: 222) Y = vlan ID (example: 223) # brctl show bridge name bridge

Hi list When I create a domU the network isn''t reachable when it''s loaded. Only if I do a xm console domUname and do some sort of network activity like pinging an outside host or traceroute. First then there''s network connection from the outside to services like webserver etc. What can cause this? I''m using Xen 2.0.5 stable domU from binary dist and

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

Hi, I will try to explain my case, I hope this is rigth place to do it. My goal is migrate an Ubuntu 9.10 64bit VMWare VM from a Win2k8 64bit server to an Ubuntu 9.10 64bit server. Following some tutorials I've got a .qcow2 file from .vmdk and a .xml file from .vmx file Running virsh define/start all was fine, but VM is unaccessible: no ping, no ssh, also from hosting server. This is

Hi. I have a Shuttle box with an AMD Athlon XP 2200+ and 1GB of RAM. I''m normally running it with Debian sarge/sid and kernel 2.6.10-1-k7, as built by Debian. I want to use Xen on it. I built a xen0 kernel which is as close to the Debian kernel as I can (no power management, no HPET timers, broken ISA drivers disabled), disabled /lib/tls, and booted with the new kernel. Everything works.

Hi! I have a problem with my new Xen setup. I have installed Debian etch with netinstall and I''m using 2.6.18-6-xen-amd64 kernel in my dom0 and 3.0.3-0-4 version xen hypervisor. I''m using four network cards on my system and using three of them as xen bridges and dom0 is using the fourth one only for it''s own. So basicly both of my virtual servers use a network card

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)

Raffaele If you don't want to see much arp traffic on eth1, assuming that you have a subnet 10.190.190.0/24, with 10.190.190.1 on eth1 and the rest of the hosts on eth0, you can use for example, the following filter ebtables -N f1 ebtables -P f1 DROP ebtables -t filter -A FORWARD -i eth0 -o eth1 -p ARP -j f1 ebtables -t filter -A f1 -p ARP --arp-ip-src 10.190.190.0/24 --arp-ip-dst

I'm trying to bridge a wired network and a wireless network, but I'm having some trouble. No traffic seems to be passing through the bridge. When I issue a "showmacs" command to brctl, I am able to see MAC addresses from both networks. I am also able to ping both networks from the bridge machine. When I issue a "showstp" command to brctl, the wireless access

Hello, I how an embedded processor that needs to act as a bridge between a wireless and wired network. I have managed to bring up the bridge fine. I can also bring up the bridge with a static ip address. However I can not figure out how to bring up the bridge with a dynamic ip address. Is it possible to for a bridge to get a dynamically assigned ip address? Oliver
