systemid(F) 06 January 1993 systemid(F) Name systemid - the Micnet system identification file Description The systemid file contains the machine and site names for a system in a Micnet network. A machine name identifies a system and distinguishes it from other systems in the same network. A site name identifies the net- work to which a system belongs and distinguishes the network from other networks in the same chain. The systemid file may contain a site name and up to four different ma- chine names. The file has the form: [site-name] [machine-name1] [machine-name2] [machine-name3] [machine-name4] The file must contain at least one machine name. The other machine names are optional, serving as alternate names for the same machine. The file must contain a site name if more than one machine name is given or if the network is connected to another through a UUCP link. The site name, when given, must be on the first line. Each name can have up to eight letters and numbers but must always begin with a letter. There is never more than one name to a line. A line beginning with a number sign (#) is considered a comment line and is ignored. The Micnet network requires one systemid file on each system in a network with each file containing a unique set of machine names. If the network is connected to another network through a UUCP link, each file in the network must contain the same site name. The systemid file is used primarily during resolution of aliases. When aliases contain site and/or machine names, the name is compared with the names in the file and removed if there is a match. If there is no match, the alias (and associated message, file, or command) is passed on to the specified site or machine for further processing.
