Installation of PPP

[Note]

Note

PPP support must be compiled into the kernel or available as a kernel module.

Install PPP by running the following commands: 

./configure --prefix=/usr &&
make

This package does not come with a test suite.

Now, as the root user: 

make install &&
make install-etcppp

Command Explanations

make install-etcppp: This command puts example configuration files in /etc/ppp.

Configuring PPP

Configuration Information

The PPP daemon requires very little configuration. The main trick is scripting the connection. This can be done either using the chat program which comes with this package or by using WvDial-1.54.0.
