They're part of User Mode Linux (UML), an old way of virtualizing Linux. 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@xxxxxxxxxxxxxxxxx> ' <http://www.georgeanelson.com/>
