UUCP Database Files
A major part of UUCP setup is the configuration of the files that compose
the UUCP database. These files are in the /etc/uucp directory. You need to
edit these files to set up UUCP or asppp on your machine. The files
include the following:
- Config
Contains a list of variable parameters. You can manually set these parameters to configure the network.
- Devconfig
Used to configure network communications.
- Devices
Used to configure network communications.
- Dialcodes
Contains dial-code abbreviations that can be used in the phone number field of Systems file entries. Though not required, Dialcodes can be used by asppp as well as UUCP.
- Dialers
Contains character strings that are required to negotiate with modems to establish connections with remote computers. Dialers is used by asppp as well as UUCP.
- Grades
Defines job grades, and the permissions that are associated with each job grade, which users can specify to queue jobs to a remote computer.
- Limits
Defines the maximum number of simultaneous uucicos, uuxqts, and uuscheds that are permitted on your machine.
- Permissions
Defines the level of access that is granted to remote hosts that attempt to transfer files or execute commands on your machine.
- Poll
Defines machines that are to be polled by your system and when they are polled.
- Sysfiles
Assigns different or multiple files to be used by uucico and cu as Systems, Devices, and Dialers files.
- Sysname
Enables you to define a unique UUCP name for a machine, in addition to its TCP/IP host name.
- Systems
Contains information that is needed by the uucico daemon, cu, and asppp to establish a link to a remote computer. This information includes the following:
Several other files can be considered part of the supporting database but are not
directly involved in establishing a link and transferring files.
Configuring UUCP Database Files
The UUCP database consists of the files that are shown in UUCP Database Files. However,
basic UUCP configuration involves only the following critical files:
/etc/uucp/Systems
/etc/uucp/Devices
/etc/uucp/Dialers
Because asppp uses some of the UUCP databases, you should understand at minimum these
critical database files if you plan to configure asppp. After these databases are configured,
UUCP administration is fairly straightforward. Typically, you edit the Systems file first, then edit the
Devices file. You can usually use the default /etc/uucp/Dialers file, unless you plan to
add dialers that are not in the default file. In addition, you might also
want to use the following files for basic UUCP and asppp configuration:
/etc/uucp/Sysfiles
/etc/uucp/Dialcodes
/etc/uucp/Sysname
Because these files work closely with each other, you should understand all their contents
before you make any changes. A change to an entry in one file
might require a change to a related entry in another file. The remaining files
that are listed in UUCP Database Files are not as critically intertwined.
Note - asppp uses only the files that are described in this section. asppp does not use
the other UUCP database files.
