    can't bridge to wlan0

    brucelondon Novice

       

      Hi

       

       

      I have an anoying problem where I can't bridge to a wireless (wlan0) interface. I've tried using two different

       

       

      versions of vmware server on two different boxes....same story.

       

       

      My setup:

       

       

            Fedora 8 x64 on AMD with RaLink RT2500 (using kernel module or compiled driver)                

       

       

      Fedora 8 x64 Intel Core 2 duo with PRO/Wireless 3945ABG (standard built in kernel module) 

       

       

      The wirless works fine on both systems. I can bridge my vmware to the "copper" nics (eth0) and everything

       

       

      is fine......but for the life of me I am unable to bridge to the wireless interface (wlan0) on either system.

       

       

       

       

       

      When bridged to the wireless (wlan0) interface, from the guest I can ping the "base" and from the base I can ping and ssh into

       

       

      the guest .....but from the guest I can't ping my default router(adsl)......the "base" can ping the router and access the internet fine.

       

       

      I have no firewall no iptables and do not use selinux.

       

       

       

       

       

      Any ideas?

       

       

      Thanks

          forgot to add the versions of vmware server I'm using:

           

           

          VMware-server-1.0.5-80187

           

           

          VMware-server-1.0.6-91891

            In my experience, the vmware bridge does not work if the interface is not connected to the network during host start up.

            This could be your problem. When the system starts and the vmnet-bridge proces starts, wlan0 is not yet connected to the wireless lan.

             

            You can restart the bridge by killing and then relaunching it's process as follows:

             

              1. ps -eaf|grep vmnet-bridge*

            root 4533 1 0 Jun03 ? 00:00:00 /usr/bin/vmnet-bridge -d /var/run/vmnet-bridge-0.pid /dev/vmnet0 eth0

             

            Note the process ID (4533 in my case). Kill the bridge process and then restart it using the same command line shown in the output from the ps command:

             

              1. kill 4533*

              2. /usr/bin/vmnet-bridge -d /var/run/vmnet-bridge-0.pid /dev/vmnet0 eth0*

             

             

            It would take a little work, but I suppose you could write a script to do this.... ping the gateway until it responds (at which point you know wlan0 is connected) and then kill and restart the bridge.

              I have the same issue.  I tried restarting the wlan0 bridge but to no avail.  My host is Fedora Core 9 (but it hasn't worked even as far back as 7).

               

               

              kernel:   2.6.25.6-55.fc9.i686 #1 SMP

               

               

              vmware version:   1.0.6 build-91891

               

               

              My VM is Oracle Unbreakable Linux 4 which is equivalent to RHEL-4.  When the VM boots, it doesn't complain when doing the eth0 work and an ifconfig shows my assigned IP but I can't ping the router or do an nslookup of anything.  This same VM works when on a different machine with an eth0.  If I find a workaround, I'll post it to this thread.

                I've not yet found a work around.

                 

                 

                 

                 

                 

                I believe the issue has something to do with the MAC address and WLAN protocol. After tracing the packets I noticed that the vmware "base"

                 

                 

                does not respond to "arp" requests for the "vmware guest" when bridged to a wireless nic. Some people have stated that reducing the MTU

                 

                 

                corrects this....but it didn;t work for me. I've also tried restarting vmware after the wireless nic was started.....no joy. I think issue relates to

                 

                 

                MAC / WLAN  protocol.

                  Hi,

                   

                   

                  After I upgraded from VMware Server 1.0.2 running on Ubuntu 6.10 to VMware Server 1.0.7 I faced that bridging on wireless interface is not working anymore. It seems that I have to downgrade back to the versions I had all this working.

                   

                   

                  I have rt2500 compiled from latest CVS snapshot (also tried module which came with Ubuntu 8.04 but doesn't work any better). My wireless network inteface ra0 is for vmnet0.

                   

                   

                  This use to work very well on earlier versions. I can not try VMware Server 1.0.2 with Ubuntu 8.04, since it fails to compile  the binaries. I tried workaroundsposted to this thread with no luck.

                   

                   

                  If any one comes up with anything, I'd be glad to hear.

                   

                   

                   

                   

                   

                  BR,

                    Hi,

                     

                    I noticed this thread:

                     

                     

                     

                    http://communities.vmware.com/thread/95630

                     

                     

                     

                    The patch is working! I did following steps as root:

                     

                     

                    1) Download and apply the patch:

                     

                    • cd /tmp

                    • tar xvf /usr/lib/vmware/modules/source/vmnet.tar

                    • wget http://www.hauke-m.de/fileadmin/vmware/vmware-wireless.patch

                    • patch -p0 < vmware-wireless.patch

                    • tar cvf vmnet.tar vmnet-only

                    • mv  /usr/lib/vmware/modules/source/vmnet.tar /usr/lib/vmware/modules/source/vmnet.orig.tar

                    • mv  vmnet.tar /usr/lib/vmware/modules/source/vmnet.tar

                     

                    2) Re-configure networking by running vmware-config.pl

                     

                     

                     

                     

                     

                    • vmware-config.pl

                     

                    3) Restart the hosts

                     

                     

                     

                    Everything works now. I wonder when VMware is going to make bridging to work offcially on wireless adapters as it used to work before.

                     

                     

                     

                    BR,

                      I am experiencing a similar problem using VMware Server 1.0.6 on Vista host and various Windows guests.

                      Is there a solution for the Windows based VMware server as well?

                      Regards

                        The particular patch I was referring to works only for Linux version of VMware Server. I seriously doubt there is similar solution for Windows, since I believe VMware doesn't provide sources for vmnet on Windows.
