12.2.2. Dialup Interfaces
If you connect to the Internet via PPP dialup connection, you need a configuration file for that interface
as well.
This file is created automatically for you when you use wvdial, Network Administration Tool or
Kppp to create a dialup account. In addition, any changes to dialup account settings are reflected
in these interface configuration files. The Official Red Hat Linux Getting Started Guide contains in-
structions for using these GUI-based dialup connection tools. You can also create and edit this file
manually. A typical ifcfg-ppp0 files looks like this:
DEVICE=ppp0
NAME=test
WVDIALSECT=test
MODEMPORT=/dev/modem
LINESPEED=115200
PAPNAME=test
USERCTL=true
ONBOOT=no
PERSIST=no
DEFROUTE=yes
PEERDNS=yes
DEMAND=no
IDLETIMEOUT=600
Serial Line Internet Protocol (SLIP) is another dialup interface, although it is less commonly used.
SLIP files have interface configuration file names such as ifcfg-sl0.
Among the options not already discussed that may be used in these files:
• DEFROUTE=
answer , where answer is one of the following:
• yes — Set this interface as the default route.
• no — Do not set this interface as the default route.
• DEMAND= answer , where answer is one of the following:
