SYSFILES(F)                          UNIX System V



     Name
          sysfiles - format of UUCP Sysfiles file


     Description
          The /usr/lib/uucp/Sysfiles file lets  you  assign  different
          files  to  be used by uucp(C) and cu(C) as Systems, Devices,
          and Dialers files.

          You can use different Systems files  so  that  requests  for
          login  services can be made to different addresses than UUCP
          services.

          With  different  Dialers  files  you   can   use   different
          handshaking for cu and uucp.  Multiple Systems, Dialers, and
          Devices files are useful if any one file becomes too large.

          An active Sysfiles file is not included in the distribution.
          Instead  a  Sysfiles.eg  file  is  included,  which contains
          comments and commented examples of how such a  file  can  be
          used.  This is done because UUCP runs faster without reading
          this file.

          The format of the Sysfiles file is

            service=w  systems=x:x dialers=y:y devices=z:z

          where w is replaced by uucico(ADM), cu, or both separated by
          a  colon;  x  is one or more files to be used as the Systems
          file, with each file name separated by a colon and  read  in
          the  order  presented;  y is one or more files to be used as
          the Dialers file; and z is one or more files to be  used  as
          the  Devices  file.   Each file is assumed to be relative to
          the /usr/lib/uucp directory, unless a full path is given.  A
          backslash-carriage return (\<CR>) can be used to continue an
          entry on to the next line.

          An example of using a local Systems file in addition to  the
          usual Systems file follows:
          service=uucico:cu  systems=Systems:Local_Systems

          If this is in /usr/lib/uucp/Sysfiles, then both  uucico  and
          cu  will first look in /usr/lib/uucp/Systems.  If the system
          they're trying to call doesn't have an entry in  that  file,
          or  if  the  entries  in the file fail, then they'll look in
          /usr/lib/uucp/Local_Systems.

          When different Systems files are defined for uucico  and  cu
          services,  your  machine  will  store two different lists of
          Systems.  You can print the uucico  list  using  the  uuname
          command or the cu list using the uuname -c command.


     Examples
          The following example uses  different  Systems  and  Dialers
          files  to  separate  the  uucico  and cu-specific info, with
          information that they use in common still in  the  ``usual''
          Systems and Dialers files.

          service=uucico  systems=Systems.cico:Systems \
                          dialers=Dialers.cico:Dialers
          service=cu      systems=Systems.cu:Systems \
                          dialers=Dialers.cu:Dialers

          This next example uses the same systems files for uucico and
          cu, but has split the Systems file into local, company-wide,
          and global files.

          service=uucico  systems=Systems.local:Systems.company:Systems
          service=cu      systems=Systems.local:Systems.company:Systems
