ClearOS
ClearOS 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, designed for use in small and medium enterprises as a network gateway and network server with a web-based administration interface. It is positioned as an alternative to Windows [Small Business Server]. ClearOS is the successor to ClarkConnect. The software is built by ClearFoundation, and support services can be purchased from ClearCenter. ClearOS 5.1 removes previous limitations to mail, DMZ, and MultiWAN functions.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.
ClearOS aimed to replace, as a small business server, Windows SBS.
The last release of ClearOS was in 2020, and with no updates since then, the project appears to be discontinued.
You can still download the distribution from their site and the version is listed as ClearOS-7.9.1.342252. But that release is from October 13, 2021 and is not maintained anymore.
