ClearOS is a network and gateway server designed for small businesses and distributed environments

ClearOS (formerly named ClarkConnect) is a Linux distribution designed for use in small and medium enterprises as a network gateway and network server with easy to use web-based administration interface.

ClearOS was created in 2009 from ClarkConnect by a team at ClearFoundation.

Non-profit ClearFoundation was founded by Point Clark Networks in 2009 to develop ClearOS and other software products based on open source software. ClearOS 5.1 is more free and open than ClarkConnect having previous restrictions to users for mail removed as well as access to DMZ and MultiWAN functions.

For those of you upgrading from ClarkConnect 5.0, a live upgrade (via yum) will be made available shortly."

Update:

Clear Foundation has announced the availability of the first beta release of ClearOS 5.2, a CentOS-based distribution for small servers, firewalls and gateways: "The ClearOS Enterprise 5.2 Beta 1 release is here. Apart from squashing the important bugs, the big news with this release is the available upgrade path from ClearOS 5.1. Please keep in mind that this is still a beta, so proceed with the usual caution. Other changes since 5.2 Alpha 1 include: completed password policy engine; fixed disk usage report; updated SpamAssassin; many bug fixes. New in version 5.2: password policy engine; detailed disk usage reporting; network traffic analyzer tool; custom firewall tool; H323 support; mail aliases added to directory (improved support for Google Apps, Zarafa); base system upgraded to CentOS 5.5."
