Editing UUCP (section)

==UUCPNET and mapping<!--'UUCPNET' redirects here-->==
'''UUCPNET'''<!--boldface per WP:R#PLA--> was the name for the totality of the network of computers connected through UUCP. This network was very informal, maintained in a spirit of mutual cooperation between systems owned by thousands of private companies, universities, and so on.  Often, particularly in the private sector, UUCP links were established without official approval from the companies' upper management.  The UUCP network was constantly changing as new systems and dial-up links were added, others were removed, etc.

The ''UUCP Mapping Project'' was a volunteer, largely successful effort to build a map of the connections between machines that were [[open mail relay]]s and establish a managed namespace. Each system administrator would submit, by e-mail, a list of the systems to which theirs would connect, along with a ranking for each such connection.  These submitted map entries were processed by an automatic program that combined them into a single set of files describing all connections in the network.  These files were then published monthly in a [[newsgroup]] dedicated to this purpose.  The UUCP map files could then be used by software such as "pathalias" to compute the best route path from one machine to another for mail, and to supply this route automatically.  The UUCP maps also listed contact information for the sites, and so gave sites seeking to join UUCPNET an easy way to find prospective neighbors.
