## DESCRIPTION

This manual page documents briefly the `&dhpackage;` program.

This manual page was written for the &debian; distribution because the original program does not have a manual page.

`&dhpackage;` 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.

## OPTIONS

`-unix `control_socket` `data_socket``

- Listen on the specified pair of sockets, instead of the defaults.

`-hub`

- 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

`-compat-v0`

- Specify control protocol version 0 compatibility.

`-daemon`

- Run in the background as a daemon.
