There are a number of configuration and dialer files that need to be set up to get PPP operational. There are examples as part of the PPP distribution and this section shows what files you should have:-
/etc/ppp/options /etc/ppp/scripts/ppp-on /etc/ppp/scripts/ppp-on-dialer /etc/ppp/options.tpl
You may need to create some additional files depending on exactly what you are aiming to achieve with PPP:-
/etc/ppp/options.ttyXX /etc/ppp/ip-up /etc/ppp/pap-secrets /etc/ppp/chap-secrets
In addition, the PPP daemon can use a large number of command line options and it is important to use the right ones; so this section takes you through the standard PPP options and helps you choose the options you should use.
For details on this, see Chapter 15.
