A quick introduction to the program ipchains.
Final Considerations

Ip chains is a very powerful tool that allows you to create many complex rules in order to protect your network. Just for fun, I built a small C program to build simple firewall scripts and simplify the rc.d process. It is open source and available at linuxgo.persogo.com.br/ipchains.html. Good places to get more information on how to build great scripts are the HOWTOs (see Resources). Read them before you start to build your own firewall scripts.

Private PaaS for the Agile Enterprise

If you already use virtualized infrastructure, you are well on your way to leveraging the power of the cloud. Virtualization offers the promise of limitless resources, but how do you manage that scalability when your DevOps team doesn’t scale? In today’s hypercompetitive markets, fast results can make a difference between leading the pack vs. obsolescence. Organizations need more benefits from cloud computing than just raw resources. They need agility, flexibility, convenience, ROI, and control.

Stackato private Platform-as-a-Service technology from ActiveState extends your private cloud infrastructure by creating a private PaaS to provide on-demand availability, flexibility, control, and ultimately, faster time-to-market for your enterprise.
