# Comstop 0.1, Scot Hacker, shacker@birdhouse.org
# Latest version at http://birhouse.org/blog/software/comstop.txt

# A quick-n-dirty script to quickly rename all comment & trackback
# scripts on a site currently undergoing a comment spam attack. 
# The goal is crude -- to simply pull the comment scripts out
# from under the spammer so they'll be returned quick 404s instead.
# Of course this disables ALL commenting until the script is run in reverse!
# If run for multiple users,  we assume it's being run as root.

# This script could be amended in future versions
# to also stop apache and kill lingering threads.


# Install: Rename to "comstop" or "comstop.sh" and place in your path.
# Change the SUFFIX variable and edit the SCRIPTFILE array to suit.
# chmod 700 comstop  -- nobody else should be able to read or run this script!

# Run as "comstop do" (to rename files) or "comstop undo" (to un-rename)


############################
# Edit variables in this  section


# A made-up string to append to the end of comment script names 
# Change this to prevent educated guesses
SUFFIX=pqrs


# List paths to all files you want to rename.
# This list can be as long or as short as you like.
# TAKE CARE TO INCREMENT THE ARRAY NUMBERS!
