NAME

       socket - event signalling that a socket connection has been made

SYNOPSIS

       socket PROTO=PROTO PORT=PORT ADDR=ADDR

       socket PROTO=PROTO SOCKET_PATH=PATH

DESCRIPTION

       The  socket  event  is  generated by the upstart-socket-bridge(8) daemon when a socket connection is made
       whose details match the socket event condition and environment specified in a jobs start on  or  stop  on
       stanza.

       When an incoming connection is detected, the file descriptor representing the socket is passed to the job
       in  question  to  allow  it  to  accept(2)  the  connection.  Additionally,  the   environment   variable
       UPSTART_EVENTS  will  contain  the  name of the event ("socket") and the environment variable UPSTART_FDS
       will contain the number of the file descriptor corresponding to the listening socket.

EXAMPLES

   Internet (IPv4) socket
       Start web server when first client connects from localhost:

              start on socket PROTO=inet PORT=80 ADDR=127.0.0.1

   Internet (IPv6) socket
       Start job when a client connects from localhost:

              start on socket PROTO=inet6 PORT=80 ADDR=::1

   Local socket
              start on socket PROTO=unix SOCKET_PATH=/var/run/.s.pgsql.1234

   Abstract socket
              start on socket PROTO=unix SOCKET_PATH=@/at/upstart/example
