LanSchool

LanSchool's locally hosted software uses a proprietary remote desktop protocol that communicates over a local area network via TCP and UDP. A console application is installed on the teacher's computer, which communicates peer-to-peer with a software agent running on the pupils' computers. LanSchool can function on the Windows, macOS, Chrome OS, iOS, and Android operating systems.[2]

LanSchool Air is delivered as a cloud-based software, accessible through the teacher and students’ browsers and managed by Lenovo Software. It is compatible with Windows, macOS, and Chrome OS operating systems.[3]

Originally named LanFan Technologies, the company was founded in February 1986[4] when Dana Doggett began exploring the concept of a software application that would allow an instructor to control multiple computers.

Doggett developed a software tool called PC Chalkboard that was then implemented by Novell. PC Chalkboard allowed Novell lab instructors to broadcast their screens to each PC in the lab. LanSchool was licensed by both Intel and IBM and actively marketed through each company's education sales channel. In April 2001, Doggett left Intel and formed a new company, LanSchool Technologies, LLC, where he could work on LanSchool full-time.

LanSchool was acquired by Stoneware in 2011. In September 2012, Lenovo announced the acquisition of Stoneware which was completed on December 26, 2012.[5]

There have been cases of students being able to exploit the LanSchool software to bypass restrictions, and in some cases take control of other student computers.[6] A 2006 post on CompSci.ca details the packet structure of older versions of the software, and claims there was no encryption or similar precautions. This issue was confirmed to have been caught and fixed in the same post the following year.[7]
