# logrotate_FreeRADIUS.sh
#
#
# This logrotate script is used to rotate FreeRADIUS radius.log file.
# It should be triggered by cron of ossadmin daily when installed in SINGLE_PACKAGE mode.
# It should be triggered by cron of root daily if installed in FreeRADIUS only mode.
#
# The Radius log file, radius.log, grows continuously and can become
# too large to view after several months of normal operation.  This
# script, when run periodically, solves this operational problem by 
# renaming and saving the current log file and allowing Radius
# server to start a new radius.log file.
#
# When this file is run, the current radius.log file is renamed and then
# gzipped.  The file name for the backup is radius.log-YYYYMMDD-HH:MM.gz.
# Where YYYYMMDD-HH:MM stands for the year, month, day, hour and minute 
# when the log file was backed up.  When the radius.log file is renamed 
# and backed up, a new radius.log file is automatically written in the 
# $RADIUS_HOME/freeradius/var/log/radius directory if in SINGLE_PACKAGE mode,
# or in /usr/local/var/log/radius directory if in FreeRADIUS only mode.
#
# This script must be run by user ossadmin.
