This manual page documents briefly the uml_switch program.

This manual page was written for the Debian GNU/Linux distribution because the original program does not have a manual page.

uml_switch is a daemon for managing a virtual network between user-mode Linux systems, with no connection to the host system's network.

It will listen for connections on a pair of UNIX domain sockets, and forward packets between clients which connect to them.


-unix control_socket data_socket
Listen on the specified pair of sockets, instead of the defaults.
Act like a hub. This means that packets received will be broadcast over all virtual links. The default is to act as a switch, where packets are only sent to the link matching the destination MAC address of the packet.
-tap tap device
Connect the switch to a dynamically created tap device on the host
Specify control protocol version 0 compatibility.
Run in the background as a daemon.
