Hi all, if you're working with ubuntu, you could also setup bridge-utils (apt-get install bridge-utils) on your host and try the following scripts:
-- qemu-start-nw ! #!/bin/sh ! # ! # This script requires qemu 0.11.50 or newer and a host ! # system with bridge utils. Must be run as root. ! ! qemu-ifup tap0 ! ! qemu -kernel $1 -serial stdio -m 1024 -usbdevice mouse -usbdevice keyboard -net nic,model=pcnet,macaddr=00:81:71:61:51:41 -net tap,ifname=tap0,script=no,downscript=no ! ! qemu-ifdown tap0 $1 would be the weaver.elf file. Don't make the first byte of the assigned mac address an odd number, because that would be a multicast mac address which might be ignored by some (linux-) peers. -- qemu-ifup ! #!/bin/sh ! # ! # script to bring up the tun device in QEMU in bridged mode ! # first parameter is name of tap device (e.g. tap0) ! ! # ! # First take eth0 down, then bring it up with IP 0.0.0.0 ! # ! /sbin/ifconfig eth0 down ! /sbin/ifconfig eth0 promisc up ! ! # ! # Bring up the tap device (name specified as first argument, by QEMU) ! # ! /usr/sbin/openvpn --mktun --dev $1 --user `id -un` ! /sbin/ifconfig $1 up ! ! # ! # create the bridge between eth0 and the tap device ! # ! /usr/sbin/brctl addbr br0 ! /usr/sbin/brctl addif br0 eth0 ! /usr/sbin/brctl addif br0 $1 ! /sbin/ifconfig br0 up ! ! # ! # only a single bridge so loops are not possible, turn off spanning tree protocol ! # ! /usr/sbin/brctl stp br0 off -- qemu-ifdown ! #!/bin/sh ! # ! # Script to bring down and delete bridge br0 when QEMU exits ! # ! # Bring down eth0 and br0 ! # ! /sbin/ifconfig eth0 down ! /sbin/ifconfig $1 down ! /sbin/ifconfig br0 down ! # ! # Delete the bridge ! # ! /usr/sbin/brctl delbr br0 ! # ! # bring up eth0 in "normal" mode ! # ! /sbin/ifconfig eth0 -promisc ! /sbin/ifconfig eth0 up ! # ! # delete the tap device ! # ! /usr/sbin/openvpn --rmtun --dev $1 Perhaps you must prevent local networking from using the bridged interface (for whatever reason, this does not seem to work in my case) ! route del -net 192.168.1.0 netmask 255.255.255.0 dev eth0 ! route add -net 192.168.1.0 netmask 255.255.255.0 dev wlan0 Good luck Sven Christian Helmuth wrote: > Hello Peter, > > On Mon, Feb 22, 2010 at 11:29:38AM +1030, Peter Nguyen wrote: > >> Is anyone able to give me some pointers on how to set up the TAP version >> of the HTTP server?
