The procedure uses the PPP configuration files that were introduced in How to Define Communications Over the Serial Line (Dial-in Server) as examples.
Log in to the dial-in server as superuser.
Add authentication options to the /etc/ppp/options file.
For example, you would add the options in bold to an existing /etc/ppp/optionsfile to implement PAP authentication:
lock idle 120 nodefaultroute name myserver auth require-pap user myserver remotename user2 login |
Create an /etc/ppp/options.ttyname file, as described in How to Define Communications Over the Serial Line.
Set up the $HOME/.ppprc file for each remote caller, as explained in How to Configure Users of the Dial-in Server.
