<title>Description</title>
|
||
|
||
<para><command>systemd-socket-activate</command> may be used to launch a socket-activated service program from the
|
||
command line for testing purposes. It may also be used to launch individual instances of the service program per
|
||
connection.
|
||
</para>
|
||
|
||
<para>The daemon to launch and its options should be specified
|
||
after options intended for <command>systemd-socket-activate</command>.
|
||
</para>
|
||
|
||
<para>If the <option>--inetd</option> option is given, the socket file descriptor will be used as the standard
|
||
input and output of the launched process. Otherwise, standard input and output will be inherited, and sockets will
|
||
be passed through file descriptors 3 and higher. Sockets passed through <varname>$LISTEN_FDS</varname> to
|
||
<command>systemd-socket-activate</command> will be passed through to the daemon, in the original positions. Other sockets
|
||
specified with <option>--listen=</option> will use consecutive descriptors. By default,
|
||
<command>systemd-socket-activate</command> listens on a stream socket, use <option>--datagram</option> and
|
||
<option>--seqpacket</option> to listen on datagram or sequential packet sockets instead (see below).
