NAME
       udpxrec - a programmable	multicast traffic recording utility.

SYNOPSIS
       udpxrec	[-v]  [-b _begin_time_]	[-e _end_time_]	[-M _maxfilesize_] [-p
       _pidfile_] [-B _bufsizeK_] [-n _nice_incr_] [-u _seconds_to_wait_]  [-m
       _mcast_ifc_addr_] [-l _logfile_]	-c _src_addr_:_port_ _dstfile_

DESCRIPTION
       udpxrec	is a utility designed to record	(save into a disk file)	a seg-
       ment of multicast network traffic; the amount  of  data	saved/recorded
       could be	specified in length (KB) or duration (seconds).

OPTIONS
       udpxrec accepts the following options:

       -v      Enable verbose output [default =	disabled].

       -T      Do NOT run as a daemon [default = daemon	if root].

       -m _mcast_ifc_addr_
	       IPv4   address/interface	  of  (multicast)  source  [default  =
	       0.0.0.0].

       -l _logfile_
	       Log output to file [default = stderr].

       -n _nice_incr_
	       Nice value increment [default = 0].

       -B _sizeK_
	       Buffer size (65536, 32Kb, 1Mb)  for  inbound  (multicast)  data
	       [default	= 2048 bytes].

       -R _msgs_
	       Maximum number of messages to buffer (-1	= all) [default	= 1].

       -b _begin_time_
	       Begin  recording	 at  [+]dd:hh24:mi.ss,	'+' signifies relative
	       timing (in N hours/min/sec).

       -e _endtime_
	       Stop recording at [+]dd:hh24:mi.ss, '+' signifies relative tim-
	       ing (in N hours/min/sec).

       -M _maxfilesize_
	       Maximum size of destination file.

       -p _pidfile_
	       Pidfile for this	process	[MUST be specified if daemon].

       -u _seconds_to_wait_
	       Seconds	to  wait  before  updating  on how long	till recording
	       starts.

EXAMPLES
       udpxrec	-b  15:45.00  -e  +2:00.00  -M	1.5Gb	-n   2	 -B   64K   -c
       224.0.11.31:5050	/opt/video/tv5.mpg

       Begin recording multicast channel 224.0.11.31:5050 at 15:45 today, fin-
       ish recording in	two hours or if	destination file size >= 1.5  Gb;  set
       socket  buffer to 64Kb; increment nice value by 2; write	captured video
       to /opt/video/tv5.mpg.
