Dialback is a set of html pages and some bash
scripts to enable a host to call you back and set
up a ppp link. It also includes a MS Windows
dial-up networking script should you wish to use
such a machine for a client. It is intended for
legitimate remote access where you need good
security (ppp link only available on return call)
and/or the other end is willing to foot the bill
for your connection time. Please note that it
should be fairly to set up other protocols such as
slip.
