Although UUCP was originally developed on and is most closely associated with Unix , UUCP implementations exist for several other operating systems, including Microsoft's MS-DOS , Digital's VAX/VMS , Commodore's AmigaOS , and Mac OS . TECHNOLOGY UUCP can use several different types of physical connections and link-layer protocols, but was most commonly used over dial-up connections. Before the widespread availability of Internet connectivity, computers were only connected by smaller private networks within a company or organization. They were also often equipped with Modems so they could be used remotely from character-mode terminals via dial-up lines. UUCP uses the computers' modems to dial out to other computers, establishing temporary, point-to-point links between them. Each system in a UUCP network has a list of neighbor systems, with phone numbers, login names and passwords, etc. When ''work'' (file transfer or command execution requests) is queued for a neighbor system, the uucico program typically calls that system to process the work. The uucico program can also poll its neighbors periodically to check for work queued on their side; this permits neighbors without dial-out capability to participate. Today, UUCP is rarely used over dial-up links, but is occasionally used over TCP/IP . |
