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
