This HOWTO covers connecting User-mode Linux sessions to a physical network by means of the 802.1d Ethernet bridging support available in the Linux kernel. Networking UML sessions in this way enables them to appear and behave as if they were a part of the real LAN. A familiarization with Linux and kernel recompilation is assumed.
