TRACE-CMD-LISTEN(1)													       TRACE-CMD-LISTEN(1)

NAME
trace-cmd-listen - listen for incoming connection to record tracing. SYNOPSIS
trace-cmd listen -p port [OPTIONS] DESCRIPTION
The trace-cmd(1) listen sets up a port to listen to waiting for connections from other hosts that run trace-cmd-record(1) with the -N option. When a connection is made, and the remote host sends data, it will create a file called trace.HOST:PORT.dat. Where HOST is the name of the remote host, and PORT is the port that the remote host used to connect with. OPTIONS
-p port This option will specify the port to listen to. -D This options causes trace-cmd listen to go into a daemon mode and run in the background. -d dir This option specifies a directory to write the data files into. -o filename This option overrides the default trace in the trace.HOST:PORT.dat that is created when a remote host connects. -l filename This option writes the output messages to a log file instead of standard output. SEE ALSO
trace-cmd(1), trace-cmd-record(1), trace-cmd-report(1), trace-cmd-start(1), trace-cmd-stop(1), trace-cmd-extract(1), trace-cmd-reset(1), trace-cmd-split(1), trace-cmd-list(1) AUTHOR
