ClearOS explained
ClearOS (also known as the ClearOS System, formerly ClarkConnect[3]) is a Linux distribution by ClearFoundation, with network gateway, file, print, mail, and messaging services.
History
ClearOS is based on CentOS and Red Hat Enterprise Linux,[4] designed for use in small and medium enterprises as a network gateway and network server with a web-based administration interface.[5] It is positioned as an alternative to Windows Small Business Server.[6] ClearOS is the successor to ClarkConnect. The software is built by ClearFoundation, and support services can be purchased from ClearCenter.[7] ClearOS 5.1 removes previous limitations to mail, DMZ, and MultiWAN functions.[8]
As of the ClearOS 6.1 release, the distribution is a full-featured operating system for gateway, network and servers built from source packages for Red Hat Enterprise Linux.[9] [10] [11]
ClearOS aims to replace, as a small business server, Windows SBS.
