similar to: [Bridge] Strange DHCP behaviour with bridging

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

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

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

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

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

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

inquiry about differences between the tap and the vnet in the virt-manager Greetings! I encounter a problem about the network when using virt-manager to create and run a VM. when I want to establish a network bridge for the guest OS, I generally use two kinds of ways described as fellow : First method : create a bridge with the help of linux commad: brctl, or Second method : using

Hello all, I subscribed newly to this list, since I got an bridging problem after an upgrade from Debian etch to Debian lenny (before everything worked fine). The situation is as follows: # brctl show bridge name bridge id STP enabled interfaces br0 8000.000347729835 no eth0 tap0 tap0

Hello, I thinking about using PCI passthrough to dedicated a domU as firewall. I understand PCI passthrough concept. When done, my domU will see network card and the dom0 won''t any more. So I''ll be able to filter all trafic from outside, since it will go through network domU. Then, how will I be able to connect other domU (and maybe dom0) to the network domU ? In a normal way,

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.

Hi. I spawned a thread last week about the failure of bridged networking and I have gotten a little further. Turns out that I _do_ have network connectivity from inside the domains, but I cannot get the network to come up when I boot. I have to login and start up the network manually. E.g. after installing Debian Sarge according to the debootstrap method outlined in the users manual, I created a

Hello list, Please don''t shoot me. I know I''m doing something with bonding that bonding wasn''t made for. I just want to give it a try. I want a simple mechanism to have a failover on a 24Mbit line to a 2Mbit line in case the 24Mbit line goes down. Between A and B there are two lines: a 24Mbit and a 2Mbit. I use two OpenVPN tunnels with tap devices: +-- tap0 (A)---
