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

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 have been asking on the qemu list how to get bridge network mode working under centos 4... To no avail. The following script is what I have tried as my /etc/qemu-ifup. It supposedly worked for fedora. #!/bin/sh # # qemu_up # # script to bring up the tun device in QEMU in bridged mode # # This script bridges eth0 and tap0. First take eth0 down, then bring it up with IP 0.0.0.0 # /sbin/ifdown

Hello Tinc list! I'm trying to set up a Tinc VPN between two KVM host machines so that a VM on one host can communicate with a VM on the other host. While I do have a good bit of experience with virtualization, I'm not a particularly savvy network guy, so this is proving to be a pretty big challenge. Requirements: * ALL VM network traffic must be secure. * VMs on one host must be

Hi, I am in the process of conteinerization of server infrastructure, and my idea is to run telephony server appliance Trixbox under KVM (which in tuen uses QEMU codebase) on SuSE Linux. KVM networking is rather primitive, and the only way to make KVM''ed OS seen as "normal" computer is to use virtual bridge as I found on net. The questions are (based on the

How does the libvirt deal with the vnet mac address? Greetings, if I establish a network for the VM (hypervisor is KVM) using bridge in the virt-manager , a vnet0 device is created . There are some relationships about mac address between the vnet0 device in the hypervisor and the ethX device in the VM, for example : the mac address of vnet0 is FE:54:00:84:E3:62 the mac address of ethX in the VM

Hello all, I'm trying to bridge the wlan0 and eth0 on an embedded system. I used the following commands to setup the bridge: ifconfig eth0 0.0.0.0 promiscuous ifconfig wlan0 0.0.0.0 promiscuous brctl addbr br0 brctl addif br0 eth0 brctl addif br0 wlan0 brctl sethello br0 1 brctl setmaxage br0 4 brctl setfd br0 4 ifconfig br0 up The eth0 is connected to a local network, and wlan0 is set to

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

<I apologize if this arrives twice...

So right now, there's no vlan trunking going on on the link my bridging firewall sits

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

Hello All, I am trying to implement OpenVPN on Fedora core Linux 3 with the latest pathces installed. This server is used only as firewall/internet gateway/proxy/VPN server, with kernel 2.6.1-1.27.FC3 and kernel 2.6.1-1.27.FC3 SMP It has two NIC''s eth0 (10.0.0.150) connected to ADSL, eth1 (192.168.3.12) connected to the local network.

Hi there, I'm currently experiencing a minor problem using the bridge module under kernel 2.4.27 part of the Devil Linux distribution (http://www.devil-linux.org). The problem I am having is that when the bridge is unloaded during a reboot I receive the following errors in /var/log/messages: Nov 14 13:22:13 src@Devil kernel: unregister_netdevice: waiting for br0 to become free.
