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: 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

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

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

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 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

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

I measured encoding speed of 24-bit WAV files. It turns out that 32-bit encoder made by GCC is ~1.7x times slower than 32-bit encoder made by MSVS. It seems that GCC creates inefficient code for 32bit * 32bit -> 64bit multiplication for 32-bit architecture. This problem affects FLAC__lpc_compute_residual_from_qlp_coefficients_wide() and FLAC__lpc_restore_signal_wide() functions. Is there any

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

I would like to open a console application from within R and then send input to the newly opened console. I can use the following to open the application ... setwd(path) system(paste(path,"icl.exe",sep="")) This allows me to type in what want, but I would like to do something like this setwd(path) system(paste(path,"icl.exe",sep=""),input=c("icl

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.

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

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

¿Alguien sabe cómo dibujar un diagrama de barras agrupado (o apilado) con diferente número de elementos en cada grupo y que la leyenda quede "correcta"? Si utilizamos barplot (o barplot2 de gplots) podemos definir una matriz con columnas las diferentes alturas para cada grupo y si un grupo tiene menos categorias simplemente asignamos NA a los elementos sobrantes de esa columna. Pero no

Hello everybody, If anybody is about to graduate and is looking for a research position, ICL at the University of Tennessee (http://icl.cs.utk.edu) is looking for a compilers person. We are looking for somebody with practical experience in compiler technology and some understanding of linear algebra. Sorry for spamming the list with non-development content, but I hope a lot of

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
