 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 other 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 exam-
    ples of how such a file can be used.  This is done because UUCP runs fas-
    ter 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 (\<Return>) can be used to continue an entry onto 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 are trying to call
    does not have an entry in that file, or if the entries in the file fail,
    then they will 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
