Hi list How is ether bonding handled with Xen? Is it possible to use bonding inside a xen virtual server by bonding dom0s eth0 and eth1 or should a domU connect to dom0s "bond0" (eth0-eth1)? Is there any xen configuration examples using bonding somewhere? Thanks :) -- Med venlig hilsen / Best regards Lars E. D. Jensen - DCmedia ledj@dcmedia.biz - http://dcmedia.biz PGP PUBLIC KEY:

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

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

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

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 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 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 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

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

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.

Thanks a lot for your hints Pasi. Due to your suggestion I open a new thread here. I have tested with model=e1000 (HVMs). As HVM configs are identical (not iso images and LVM volumes) I guess it is a xen 4.1.2* issue .. or just involved domU OS-kernels (however as it is HVM it should not play any role) Tested and correctly working OSes (getting an IP address and pinging of

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 just intalled openvpn + bridge in CentOS 6, but i get strange problems: the remote PCs cannot get the local PCs' MACs and also, the local PCs cannot get the remote PCs' MACs but when i run "brctl showmacs br0" it will list all the MACs and also " brctl show" will show that all the correct adapters are in br0 SELinux disabled any ideas? -- Tang

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

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've posted here about this before, but I realise that it may have been assumed that the bridged vlans simply put a switch port in a blocking state and left my question ignored. So to recap. I have two tg3 interfaces named 'in' and 'out' and a bridge named 'br0' My vlan trunk is on the 'in' side of the network, and set as in.2, in.3 ... The

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

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

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
