- -> 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.
