Description:

o apache-monitor.pl - monitors mod_status output and stores web
server activity in a RRD file.

o apache-monitor-graph.pl - creates pretty graphs from a RRD file
populated by the previous script (you can find an example here).

o apache-protect - monitors mod_status output to detect a DoS
attack, then uses the blacklist tool to cut the offending IP
address at the firewall.

o error_log_ai.pl - implementation of the Artificial Ignorance
concept (devised by Marcus J. Ranum) for the Apache error log.

o blacklist - uses iptables to create a temporarily blacklist.

o blacklist-webclient.c - a C program that can be marked suid
root, and called from a non-root script to blacklist IP
addresses.

o logscan.pl - easy-to-use log analysis script, supports field
names and regular expressions (will support anti-evasion
techniques in the future).

o mod_globalerror.c - Apache 2 module that allows the server to
have per-virtual host error logs *and* have one file where all
errors are duplicated (useful for server monitoring).
