NAME

socket - event signalling that a socket connection has been made  

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 representing 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 environment variable UPSTART_FDS will contain the number of the file descriptor corresponding to the listening socket.
