SYSTEMID(M) XENIX System V SYSTEMID(M)
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 network 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 machine 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 pound 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.
