socket-event


SYNOPSIS
       socket PROTO=PROTO PORT=PORT ADDR=ADDR

       socket PROTO=PROTO 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 represent-
       ing  the  socket  is  passed  to  the  job  in  question to allow it to
       accept(2)  the  connection.  Additionally,  the  environment   variable
       UPSTART_JOB will contain the name of the event ("socket") and the envi-
       ronment variable UPSTART_FDS  will  contain  the  number  of  the  file
       descriptor corresponding to the listening socket.

EXAMPLES
   Internet socket
       Start web server when first client connects from localhost:

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

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

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