This directory is for random scripts that I've found to be useful in conjunction with Spackle. 'listenports' is a script I use with the 'net.ip' target to generate chains for monitoring all incoming and outgoing traffic for each listening port. Having 'listenports' run from a cronjob hourly allows me to make sure all ports are covered.
Please be careful when playing with iptables, especially on a machine you only have remote access to. :)
