https://www.shrubbery.net/rancid/%|%RANCID%|%, by https://www.shrubbery.net/company.html%|%Shrubbery Networks%|%, is a tool to retrieve network equipment (routers, switches, ...) configuration and put it under version control. It provides ''archival'' and ''change detection'' over a wide range of vendors out-of-the-box, and can be extended to support more if needed using scripting (a combination of [Perl] and [Expect] is mainly used). The system includes a web-based ''looking glass'' (which allows cached access to certain router commands via CGI). <<categories>>Expect
