- <title>Description</title>
- <para>
- <command>systemd-socket-proxyd</command> is a generic
- socket-activated network socket forwarder proxy daemon for IPv4,
- IPv6 and UNIX stream sockets. It may be used to bi-directionally
- forward traffic from a local listening socket to a local or remote
- destination socket.</para>
-
- <para>One use of this tool is to provide socket activation support
- for services that do not natively support socket activation. On
- behalf of the service to activate, the proxy inherits the socket
- from systemd, accepts each client connection, opens a connection
- to a configured server for each client, and then bidirectionally
- forwards data between the two.</para>
- <para>This utility's behavior is similar to
- <citerefentry project='die-net'><refentrytitle>socat</refentrytitle><manvolnum>1</manvolnum></citerefentry>.
- The main differences for <command>systemd-socket-proxyd</command>
- are support for socket activation with
- <literal>Accept=false</literal> and an event-driven
- design that scales better with the number of
- connections.</para>
