The $HOME/.ppprc file is not needed on the dial-out machine for Solaris PPP 4.0 to work correctly. Additionally, you do not need to have a $HOME/.ppprc on a dial-out machine, except for special circumstances. Create one or more .ppprc files if you do the following:

Need to specify options that control problems specific to your link, such as disabling Van Jacobson compression. See James Carlson's PPP Design, Implementation, and Debugging and the pppd(1M) man page for assistance in troubleshooting link problems.
Because the .ppprc file is most often used when configuring a dial-in server, refer to How to Configure Users of the Dial-in Server for configuration instructions for .ppprc.
