Open source firewall (firewall) SINUS
In fact, for the firewall, the domestic dome is indeed a lot, and then the introduction seems to be very significant, but when I first saw Sinus, I was deeply attracted by it. First, it is completely developed in its source code, and more importantly, its source code is quite good. Almost every C-headed expression is covered by notes. SINUS's firewall core part and log tools are completely written in C-language, and the user interface is written in Java, regardless of the program use C or Java, its annotations are first-class, very clear Ming. If you want to learn the design of the firewall, see its source code effect must be very wrong. On the other hand, SINUS provides a comprehensive help document that can be found in its source package. In its website, there is also a very comprehensive document. From the above two aspects, Sinus is a good learning and research material. Although it has not been officially implanted other operating operating operating systems, I think if you know C and understand software engineers who know Java, you can Design is more convenient to use a lot of things and transplanted to other UNIX operating systems. The SINUS firewall mainly includes the following functions: 1. Filtering of all Header Fields in the IP, TCP, UDP, ICMP, IGMP Packets. 2. Intelligent Rip and FTP Support. 3. Easy to understand, Text-based Configuration. 4. Graphical .. management interface for configuration of several firewalls 5. Dynamic rules, including counters and time-outs 6. Extensive logging, alerting, and counter intelligence 7. Prevention of packet and address spoofing -. GNU GPL license Functionally, it. Dynamic rules, intelligent counters, warnings, logs, and simple and easy to understand, text-based configuration and graphic management based on graphic management are worthy of use and learning. To install SINUS, you need Linux 2.0 or more kernel support. It is recommended not to install x and beautiful interfaces. Don't install user accounts to the firewall system, and don't allow users to log in remotely from the console (if you want to use it, it is recommended that you install SSH). About Sinux FireWall more detailed information, please check its official station: http://www.ifi.unizh.ch/ikm/sinus/, I believe that the documents and information it provides will be a considerable gain.
