If you are fortunate enough to have a semi permanent connection to the net and
would like to have your machine automatically redial your PPP connection if it
is lost then here is a simple trick to do so.
Configure PPP such that it can be started by the root user by issuing the
command:
Be sure that you have the `
-detach' option configured in your
/etc/ppp/options file. Then, insert the following line into your
/etc/inittab file, down with the 
getty definitions:
| pd:23:respawn:/usr/sbin/pppd | 
This will cause the 
init program to spawn and monitor the
pppd
program and automatically restart it if it dies.
