Sysfiles(4bnu)

Sysfiles -- BNU administrative file pathname definitions

Synopsis

service=srvc[:srvc...] \
systems=sysfile[:sysfile...] \
dialers=dialfile[:dialfile...] \
devices=devfile[:devfile...]

Description

The /etc/uucp/Sysfiles file gives the administrator the ability to break the logical Systems, Dialers and Devices files into multiple physical files. This makes it possible for uucp(1bnu) and cu(1bnu) to use different Systems, Dialers and Devices files.

Each entry in the Sysfiles file consists of a single logical line. Physical lines may be terminated by a backslash (\) to indicate that the entry continues on the next line. Comment lines begin with a hash sign (#) and occupy the entire line up to a newline character. Blank lines are ignored (even within multi-line entries).

Each entry in the file has the following meaning: where:

srvc specifies cu, uucico, or both separated by a colon
sysfile specifies one or more files to be used as the Systems(4bnu) file
dialfile specifies one or more files to be used as the Dialers(4bnu) file
devfile specifies one or more files to be used as the Devices(4bnu) file

Multiple filenames must be separated by colons. Each file is read in the order presented. The location for each file is assumed to be relative to the /etc/uucp/ directory, unless a full pathname is given.

Files

/etc/uucp/Devices
/etc/uucp/Dialers
/etc/uucp/Systems

Usage

The Sysfiles file may be useful in the following conditions:

you want different Systems files so that requests for cu services can be made to addresses other than the addresses used for uucico services
you want different Dialers files to use different chat scripts for cu and uucico
you want to have multiple Systems, Dialers and Devices files to simplify BNU administration. The Systems file, in particular, may become large, making it desirable to split it into several smaller files.

When different Systems files are defined for uucico and cu services, your machine will store two different lists of systems. To print the uucico list, use the uuname(1bnu) command; to print the cu list, use the uuname -c command.

Examples

The following is an example of a Sysfiles file:

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