--- NEW FILE: radius.monitor ---
#!/usr/bin/perl
#
# Monitor radius processes
#
# Based upon radius.monitor by Brian Moore, posted to the mon mailing list
#
# Arguments are:
#
# --username=user --password=pass --secret=secret
#	[--port=#] [--attempts=#] [--dictionary=/path/to/dictionary]
#	hostname [hostname ...]
#
# Arguments are in standard POSIX format and can be given as the least
# significant part (i.e. -p is the same as --password).
#
# This monitor performs a real RADIUS check, attempting to be as much like a
# terminal server as possible.  This requires that you include a username,
# password, and secret in your mon.cf file.  Depending on your unix
# implementation, this may allow unscrupulous users to view the command line
# arguments, including your RADIUS secret.  If you prefer, you can uncomment
# three lines below (see comments) to provide defaults for username,
# password, and secret.
#
# This monitor attempts to check a username and password up to n times
# (defaults to 9, but can be set via the --attempts=# command line switch). 
# It only registers a failure to mon after failing to receive a satisfactory
# response n times.  It returns an immediate failure to mon if it receives a
# failed authentication.  For this reason, you will need to create a dummy
# user on your RADIUS server for authentication testing.
