##  Clamav Signature Updater
##  Version 3.0; Copyrighted: 2006
##  Program Name: scamp.sh
##  Author: Gerard Seibert
##  Contact: gerard@seibercom.net
##  This program is free for individual use
##  You may modify this program in any way you so desire
##  The author assumes no responsibility for any changes made
##  to this program
##  Updates both scam.ndb.gz and phish.ndb.gz files
##  You will need to make sure that the paths are correct for your system
##
##  **********************************************************************
##  You will probably need to chmod this script to 0755
##  This script must be run as root.
##  You need 'wget' installed.
##  Make sure the path is correctly set
##  Using 'which wget' sans quotes, should show the path.
##  Check the path for 'chown'and 'chmod' also.
##  Alter the paths for them in the variables table at the
##  top of the program.
##  Make sure the 'clamav' setting is correct.
##  Report any problems to me at the address above!
##
##  Usually running from 'roots' CRONTAB
##  every four (4) hours will suffice.
##
##  Example (root's crontab)
##  
##  min hour mday month wday command
##  1   */4  *    *     *    /*path*/*to*/scamp.sh
##
##  Be sure to change the 'L_DIR' variable to accommodate your system.
##  This will write a log file detailing what 'wget' has fetched.
##  Example: L_DIR="/path/to/log/file" You need the quote marks.
##  DO NOT alter the N_DIR variable
##  Make sure the file is writeable.
##  If no file is specified, the script will issue a warning and exit.
##  I may change this behavior at some point in the future.
##
##  The shebang is set for 'bash' on a FreeBSD 6.1 STABLE system.
##  You may need to change it to accommodate your system.
##
##  If you find this program useful, discovered a bug,
##  or just need help, email me at the address at the top of this page.
