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 Ad-hoc mode with proper SSID. After the bridge is stablized, I use dhclient to assign an IP for br0. Then I use a laptop to connect to the bridge. I could ping the bridge (br...

...P address but a unique MAC. On the other end of each tap device is an UML virtual machine's eth0. My machines are SuperMicro 6013 dual xeon boxes with e1000, and a 5012 box with e100 NICs. I don't believe this is a checksum issue raised a while back. STP is off. Settings for setfd and sethello make no difference. As soon as UML brings up its eth0 interface, the messages appear. I'm really not a kernel hacker, but I was able to look at previous versions of the file and more or less just comment out the "if (unlikely(fdb->is_local))" statement. This is what I've be...

I set up tap interfaces like this: >tunctl tap4 >ifconfig tap4 4.4.4.4 promisc up >tunctl tap5 >ifconfig tap5 5.5.5.5 promisc up I then set up the bridge and add the tap interfaces to it: >brctl addbr tapbr >brctl setfd tapbr 0 >brctl sethello tapbr 0 >brctl stp tapbr off >ifconfig tapbr 7.7.7.7 netmask 255.255.255.0 up >brctl addif tapbr tap4 >brctl addif tapbr tap5 I then do a ping over tap4: >ping -I tap4 8.8.8.8 and tcpdump on tap5: >tcpdump -i tap5 and see nothing. Shouldn't I see the ping requests o...

Hi! I have a problem with my new Xen setup. I have installed Debian etch with netinstall and I''m using 2.6.18-6-xen-amd64 kernel in my dom0 and 3.0.3-0-4 version xen hypervisor. I''m using four network cards on my system and using three of them as xen bridges and dom0 is using the fourth one only for it''s own. So basicly both of my virtual servers use a network card

I then tried to set the two interfaces (eth0, tap0) in non-promiscuous mode. My expectation was that the bridge would not work anymore. Nevertheless, it kept working and my two networks were still bridged. Virtual machines on the ta...

Hi. I have a Shuttle box with an AMD Athlon XP 2200+ and 1GB of RAM. I''m normally running it with Debian sarge/sid and kernel 2.6.10-1-k7, as built by Debian. I want to use Xen on it. I built a xen0 kernel which is as close to the Debian kernel as I can (no power management, no HPET timers, broken ISA drivers disabled), disabled /lib/tls, and booted with the new kernel. Everything works.

I have been playing around with the STP settings of brctl and saw something strange. I was setting the hello time, so I executed the following: # brctl sethello br0 30 Then I had a look at the value that was set: # cat /sys/class/net/br0/bridge/hello_time 2999 Much bigger than expected. I started looking at the source. In the libbridge/libbridge_devif.c file of brctl, we have the following routine: int br_set_bridge_hello_time(const char *br, struct...

But nothing changes. I used the default Xen which comes with Redhat 5.2 and tried different Redhat-Kernels, also the latest from 5.3 Also I tried different Xen version. First 2-3 different versions which come with Redhat 5.2 and its updates. Then I tried version...

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

Hey all I''m new to Linux and Virtualizing. I''m trying to dedicate my nic''s to each virtual server. For instance, virt server A would use nic1 and virt server B would use nic2 and so on. I''ve been reading some stuff for this list and to tell you the truth I''m a bit overwhelmed. We are going to run SLES10.1 and Xen. I would appreciate any assistance.

hi everyone, so,first it seemed a trivial question to me, but since I could not find anybody being neither able to answer this question nor giving a short config example. after a few sleepless nights and exhausting all the reading and research. here I am sharing my problem with all of you, in the hope of some possible solution/sugestion. or is it that this is impossible?? below my
