55 Excellent FOSS Networking Tools
Networking From A-ZThe Free/Open Source software world is cram-full of excellent networking utilities, some free of cost, some costing money, and all excellent. Cynthia Harvey rounds up a herd of 55 of them just for us.
Setting up and maintaining networks used to be something that only "super-geeks" did. Network engineers and administrators at large enterprises usually have a lot of in-depth technical knowledge about how systems work and how they communicate with each other.
But these days, lots of people have small networks at their homes and small businesses. They usually don't have the same sort of specialized knowledge, but they still need to be able to set up and troubleshoot the inevitable problems.
Fortunately, developers have created plenty of open source tools to help both groups accomplish what they need to get done. Open source tools can help you design, test, deploy, manage, monitor, or secure your network, and some can even help you build your own appliances, routers, or other hardware.
And since both enterprises and homes users are feeling the budget pinch these days, free open source networking tools are becoming more popular than ever.
For this list we've collected open source replacements for both enterprise-class networking products and consumer products. We've also tried to give you an idea of the wide variety of open source network-related tools available, but of course, we're bound to miss a few. Feel free to add your suggestions in the comments below.
