1. Principles

A PPP account is associated with a login script. This script is used to control the various options of the /usr/sbin/pppd utility. A different login script is generally needed for every type of PPP account (dedicated, fixed IP, etc.). Furthermore, some configuration is needed in scripts like /etc/ppp/ip-up. The pppdialin module provides a general solution to ease all that.

• It enhances the normal PPP account dialog and lets the admin enter various pppd and routing parameters.
• The information is stored in the file /etc/pppdialin.conf.
• A utility /usr/lib/linuxconf/lib/pppparms is used to extract the parameters for a specific account and output them, in a useful way, for a shell script.
• A general-purpose login script /usr/lib/linuxconf/lib/ppplogin takes advantage of the pppparms utility.
