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

Hi there, I'm trying to set up a man-in-the-middle scenario within a VMWare Workstation team, using brctl. What I want is the following: PC1 eth0 >---LAN-segment-1---< eth0 PCMITM eth1 >---LAN-segment-2---< eth0 PC2 Now I did the following on PCMITM (PC man in the middle): ifconfig eth0 down ifconfig eth1 down brctl addbr lnxbr0 brctl addif lnxbr0 eth0 brctl addif lnxbr0 eth1

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

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

Hi Is there a way to either: Find the real ifindex/ifname a mac-address is bound to or Find the real ifindex/ifname of an incoming packet ? I am writing a dhcp server and need to know what real interface the dhcp re= quest packet came from. An acceptable solution would be to get the interfac= e by the mac-address, but that can be faked so I would rather get the inter= face by knowing where the

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

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.

I tried to create some swap files in /dev directory for my desktop. the dd and mkswap were ok. but when I try to swapon it, i get this: # swapon /dev/myswap swapon: /dev/myswap: Invalid argument but when I mv the file to some other directory like /mnt or /, the swapon works. could sb. tell me why? -- Tang Jianwei

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

dear all: I try to configure a bridge in my embedded linux. I had fininshed these operations below: 1) configure kernel, select the option "802.1d bridge" 2) compile bridge-utils 3) issue these commands: ifconfig eth0 0.0.0.0 ifconfig eth1 0.0.0.0 brctl addbr vb brctl addif vb eth0 brctl addif vb eth1 ifconfig vb 192.168.110.24 up

Hi, all, I wish to copy over fdb(forwarding database entries) learnt over from one interface onto as they are from another interface. Like for eg : brctl showmacs br0 port no mac addr is local? ageing timer 1 00:30:1a:01:6f:e4 no 0.46 1 00:30:1a:1c:3d:b7 yes 0.00 2 00:30:1a:1c:3d:b8 yes

Hello, I am experiencing what may be a unique problem with operating the bridge. My hardware is custom Freescale MPC875 processor based with one ethernet (eth0) and one hdlc (hdlc0) WAN port and I am connecting two of these boards together using the WAN ports over a long distance - essentially two bridges in series. They are running Linux 2.6.15 with bridging enabled in the kernel

Hi, I just installed Xen in Ubuntu Hardy. DomU is not accessible either from Dom0 or external network. I used default set up network-bridge/vif-bridge from xend-conf.sxp. Bridge has got default name eth1 which is my default ethernet interface. Before creating DomU: root@jaguar-0:/home/longina# xm list Name ID Mem VCPUs State Time(s) Domain-0

Hello list, I'm setting up a virtual network consisting of several UMLs (User Mode Linux) connected with the virtual bridge. Communications works quite well between the host and the virtual machines. Setup: 2 UMLs connected via tap-devices to the bridge (tap1,tap2). The host uses the bridge-device br0 to talk to the clients. Now I want to tcpdump the traffic between host and UML1 on virtual

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 debugging a strange problem of noncommunication between two devices. The test configuration is also strange, and involves loops. Things magically start working when I run tcpdump to put the bridge interface into promiscuous mode. I also noticed this in the output of brctl showmacs. port no mac addr is local? ageing timer 1 00:40:72:04:2d:ea no

I have a OpenSuse 10.3 with xen 3.1.0 running and it''s been running fine for a few months. This past weekend it suddenly started to act up and after some troubleshooting I can now say that it seems like the guests(domU) loose the outgoing network pipe, from the console I can see that the TX counter is stuck at the same value but it''s no errors. It behaves as if whatever I try to

Hi guys, I saw this sub-element in http://libvirt.org/firewall.html, there is some confusion, what's the meaning of sub-element <ip address='X.X.X.X'> in <interface type='bridge'> of domain xml? The detail <interface> in domain xml as below: <interface type='bridge'> <mac address='52:54:00:56:44:32'/> <source

Hi, I am a beginner of bridge. I have a problem of using Fedora Core 2 to make a simple bridge. Here is my setup: The bridge computer is installed with Fedore Core 2 (with the SE Linux patch). As I know that kernel 2.6.5 is already support bridging by default, so I didn't recompile the kernel. Then I installed bridge-utils-0.9.6-1.i386. And no additional configuration is made. After
