-This directory contains support for monitoring the local clock of xntp daemons.
-
-WARNING: The scripts and routines contained in this directory are beta
-	 release!  Do not depend on their correct operation. They are,
-	 however, in regular use at University of Erlangen-Nuernberg.
-	 No severe problems are known for this code.
-
-!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
-PLEASE THINK TWICE BEFORE STARTING MONITORING REMOTE XNTP DEAMONS !!!!
-MONITORING MAY INCREASE THE LOAD OF THE DEAMON MONITORED AND MAY
-INCREASE THE NETWORK LOAD SIGNIFICANTLY
-!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
-
-
-Files are:
-
-README:
-	This file
-
-ntptrap:
-	perl script to log ntp mode 6 trap messages.
-
-	It sends a set_trap request to each server given and dumps the
-	trap messages received. It handles refresh of set_trap.
-	Currently it handles only NTP V2, however the NTP V3 servers
-	also accept v2 requests. It will not interpret v3 system and
-	peer stati correctly.
-
-	usage:
-	  ntptrap [-n] [-p <port>] [-l <debug-output>] servers...
-	
-	-n:		do not send set_trap requests
-
-	port:		port to listen for responses
-			useful if you have a configured trap
-
-	debug-output:	file to write trace output to (for debugging)
-
-	This script convinced me that ntp trap messages are only of
-	little use.
-
-ntploopstat:
-	perl script to gather loop info statistics from xntpd via mode 7
-	LOOP_INFO requests.
-
-	This script collects data to allow monitoring of remote xntp servers
-	where it is not possible to directly access the loopstats file
-	produced by xntpd itself. Of course, it can be used to sample
-	a local server if it is not configured to produce a loopstats file.
-
-	Please note, this program poses a high load on the server as
-	a communication takes place every delay seconds ! USE WITH CARE !
-
-	usage:
-	  ntploopstat [-d<delay>] [-t<timeout>] [-l <logfile>] [-v] [ntpserver]
-	
-	delay:		number of seconds to wait between samples
-			default: 60 seconds
-	timeout:	number of seconds to wait for reply
-			default 12 seconds
-	logfile:	file to log samples to
-			default: loopstats:<ntpserver>:
-			(note the trailing colon)
-			This name actually is a prefix.
-			The file name is dynamically derived by appending
-			the name of the month the sample belongs to.
-			Thus all samples of a month end up in the same file.
-
-	the format of the files generated is identical to the format used by
-	xntpd with the loopstats file:
-		MJD <seconds since midnight UTC> offset frequency compliance
-	
-	if a timeout occurs the next sample is tried after delay/2 seconds
-
-	The script will terminate after MAX_FAIL (currently 60)
-	consecutive errors.
-
-	Errors are counted for:
-		- error on send call
-		- error on select call
-		- error on recv call
-		- short packet received
-		- bad packet 
-		- error on open for logfile
-
-ntploopwatch:
-	perl script to display loop filter statistics collected by ntploopstat
-	or dumped directly by xntpd.
-
-	Gnuplot is used to produce a graphical representation of the sample
-	values, that have been preprocessed and analysed by this script.
-
-	It can either be called to produce a printout of specific data set or
-	used to continously monitor the values. Monitoring is achieved by 
-	periodically reprocessing the logfiles, which are updated regularly
-	either by a running ntploopstat process or by the running xntpd.
-
-	usage:
-	  to watch statistics permanently:
-	     ntploopwatch [-v[<level>]] [-c <config-file>] [-d <working-dir>]
-
-	  to get a single print out specify also
-			  -P<printer> [-s<samples>]
-				      [-S <start-time>] [-E <end-time>]
-				      [-O <MaxOffs>] [-o <MinOffs>]
-	
-	level:		level of verbosity for debugging
-	config-file:	file to read configurable settings from
-			On each iteration it is checked and reread
-			if it has been changed
-			default: loopwatch.config
-	working-dir:	specify working directory for process, affects
-			interpretation of relative file names
-	
-	All other flags are only useful with printing plots, as otherwise
-	command line values would be replaced by settings from the config file.
-
-	printer:	specify printer to print plot
-			BSD print systems semantics apply; if printer
-			is omitted the name "ps" is used; plots are
-			prepared using PostScript, thus the printer
-			should best accept postscript input
-
-	For the following see also the comments in loopwatch.config.SAMPLE
-
-	samples:	use last # samples from input data
-	start-time:	ignore input samples before this date
-	end-time:	ignore input samples after this date
-			if both start-time and end-time are specified
-			a given samples value is ignored
-	MaxOffs:
-	MinOffs:	restrict value range 
-
-loopwatch.config.SAMPLE:
-	sample config file for ntploopwatch
-	each configurable option is explained there
-
-lr.pl:
-	linear regression package used by ntploopwatch to compute
-	linear approximations for frequency and offset values
-	within display range
-
-timelocal.pl:
-
-	used during conversion of ISO_DATE_TIME values specified in
-	loopwatch config files to unix epoch values (seconds since
-	1970-01-01_00:00_00 UTC)
-
-	A version of this file is distributed with perl-4.x, however,
-	it has a bug related to dates crossing 1970, causing endless loops..
-	The version contained here has been fixed.
-
-ntp.pl:
-	perl support for ntp v2 mode 6 message handling
-	WARNING: This code is beta level - it triggers a memory leak;
-		 as for now it is not quite clear, wether this is caused by a
-		 bug in perl or by bad usage of perl within this script.

-;#	$time = timegm($sec,$min,$hours,$mday,$mon,$year);
-
-;# These routines are quite efficient and yet are always guaranteed to agree
-;# with localtime() and gmtime().  We manage this by caching the start times
-;# of any months we've seen before.  If we know the start time of the month,
-;# we can always calculate any time within the month.  The start times
-;# themselves are guessed by successive approximation starting at the
-;# current time, since most dates seen in practice are close to the
-;# current date.  Unlike algorithms that do a binary search (calling gmtime
-;# once for each bit of the time value, resulting in 32 calls), this algorithm
-;# calls it at most 6 times, and usually only once or twice.  If you hit
-;# the month cache, of course, it doesn't call it at all.
-
-;# timelocal is implemented using the same cache.  We just assume that we're
-;# translating a GMT time, and then fudge it when we're done for the timezone
-;# and daylight savings arguments.  The timezone is determined by examining
-;# the result of localtime(0) when the package is initialized.  The daylight
-;# savings offset is currently assumed to be one hour.
