Configuring UUCP Files

The UUCP database consists of the files shown in "Introducing the UUCP Database Files". However, basic UUCP configuration involves only the following critical files:

• /etc/uucp/Systems

• /etc/uucp/Devices

• /etc/uucp/Dialers

Because PPP uses some of the UUCP databases, you should understand at least these critical database files if you plan to configure PPP. After these databases are configured, UUCP administration is fairly straightforward. Typically, you edit the Systems file first, then edit the Devices file. You usually can use the default /etc/uucp/Dialers file, unless you plan to add dialers that aren't in the default file. In addition, you might also want to use the following files for basic UUCP and PPP configuration:

• /etc/uucp/Sysfiles

• /etc/uucp/Dialcodes

• /etc/uucp/Sysname

Because these files work closely with each other, you should understand the contents of them all before you change any one of them. A change to an entry in one file might require a change to a related entry in another file. The remaining files listed in "Introducing the UUCP Database Files" are not as critically intertwined.

PPP uses only the files described in this section. It does not use the other UUCP database files.

The rest of this chapter explain the UUCP databases in detail.
