About Linux Netwosix:

Linux Netwosix is a powerful and optimized Linux distribution for servers and Network Security related jobs. It can also be used for special operations such as penetration testing with its big collection of security oriented software and sources. It's a light distribution created for the requirements of every SysAdmin and it's very portable and highly configurable. Our philosophy is to give greater liberty for configuration to the SysAdmin. Only in this way can he/she configure a powerful and stable server machine. Linux Netwosix also has a powerful ports system (Nepote) similar to the xBSD systems but more flexible and usable.
