ClearOS (also known as the ClearOS System, formerly ClarkConnect^[4]) was 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,^[5] designed for use in small and medium enterprises as a network gateway and network server with a web-based administration interface.^[6] It is positioned as an alternative to Windows Small Business Server.^[7] ClearOS is the successor to ClarkConnect. The software is built by ClearFoundation, and support services can be purchased from ClearCenter.^[8] ClearOS 5.1 removes previous limitations to mail, DMZ, and MultiWAN functions.^[9]

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.^[10]^[11]^[12]

The last release of ClearOS was in 2020, and with no updates since then, the project appears to be discontinued.^[13]

ClearOS aims to replace, as a small business server, Windows SBS.^[14]
