SYSTEMID(F)                                UNIX System V



     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
