      The original version of SpiderFoot was created in 2005 with the goal of being a freely available open source tool for footprinting an Internet domain name.

    • FreeBSD Jails Firewall with PF

      Features are available for fully virtualizing FreeBSD jail networking (as of FreeBSD 8.x). The code has improved in the current 9.x code base but to get a jail up and running with the current install, pf provides the necessary functionality to firewall off multiple jailed services. This article will cover basic jails configuration to highlight how to configure the firewall to only allow specific traffic to the service jails.

    • Improvements to Jail Management via the Warden

      Over the past few months, several exciting new features have been added to the Warden which greatly improve jail management on FreeBSD & PC-BSD systems.Now the Warden will be able to create jails via Hostname / Nickname, and change and assign IP addresses on the fly. This greatly simplifies jail creation via the command-line, allowing you to create the jail and then set addresses as needed later.

    • Useful Utilities for PF

      PF is a stateful firewall, meaning that it tracks the state of existing connections in a state table, allowing the firewall to quickly determine if packets are part of an established connection. PF also provides a logging facility and the firewall administrator controls which packets get logged by including the log keyword in only the firewall rules which should be logged when matched. This article explores some of the third-party utilities which are available to help you analyze the log and state table of a PF firewall.
