Other ways include XEN, KVM (Kernel Virtual Machine), QEMU, VMWare, and I guess VirtualBox. As UML isn't packaged for Fedora, neither are uml-utilities. I've recently set up TUN/TAP networking for QEMU. It may be similar enough to help you. There were several hurdles. One is that recent kernels (2.6.18+) require CAP_NET_ADMIN capability in the program opening the TUN device; until the tools are available, this actually means the program must be run suid root, or an earlier kernel must be used, or the kernel must be rebuilt, either with more patches or with the new TUN requirement removed. I chose to use a patch to QEMU that runs it suid root and drops privileges after opening the TUN device. With that out of the way, I yum installed bridge-utils and wrote some scripts that do the following under sudo: /bin/chmod go+rw /dev/net/tun /user/sbin/brctl addbr br0 /sbin/ifconfig eth0 0.0.0.0 promisc up /user/sbin/brctl addif br0 eth0 /sbin/dhclient br0 /sbin/iptables -F FORWARD QEMU uses a script to connect itself to the bridge: /sbin/ifconfig $1 0.0.0.0 promisc up /usr/sbin/brctl addif br0 $1 I got this set up from various sources, including <http://linux-net.osdl.org/index.php/Bridge> and <http://kidsquid.com/cgi-bin/moin.cgi/bridge> (QEMU specific, having troubles lately, still in Google's cache). -- ____________________________________________________________________ TonyN.:' <mailto:tonynelson@georgeanelson.com> ' <http://www.georgeanelson.com/>

Fedora 7 (fc7) Instructions: Instead of uml use openvpn: chown root.vboxusers /dev/net/tun chmod g+rw /dev/net/tun Then: You might need to make tiny adjustments to the eth1 script...edit yours (probably eth0 instead of eth1 also) /etc/sysconfig/network-scripts/ifcfg-br0: DEVICE=br0 TYPE=Bridge BOOTPROTO=dhcp ONBOOT=yes /etc/sysconfig/network-scripts/ifcfg-eth1: # Broadcom Corporation NetXtreme BCM5754 Gigabit Ethernet PCI Express DEVICE=eth1 BRIDGE=br0 HWADDR=00:1A:A0:B0:AC:9F ONBOOT=yes TYPE=Ethernet USERCTL=no IPV6INIT=no PEERDNS=yes Then: services network restart openvpn --mktun --dev tap0 ifconfig tap0 up brctl addif br0 tap0 Then in virtualbox, set the network to host and set the interface to tap0. no scripts needed, but you'll have to figure out where to put the last three lines above to run automatically if you don't make a script. Note that this is on the VirtualBox-OSE 1.4 edition on x86-64. -- This is an email sent via The Fedora Community Portal https://fcp.surfsite.org https://fcp.surfsite.org/modules/newbb/viewtopic.php?post_id=193428&t...
