socket-event(7)


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
