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.
