This module allows you to setup your Linux machine with an attached modem
as a dialin server that allows other machines to dial up to it, login and open
PPP sessions. It can also be used to allow logins and PPP connections from
another machine connected directly to yours via a null-modem cable.
In order to setup dialin access, you must follow these steps :
- In the Serial Port Configuration page, add an entry for the port on
which your modem is connected. The will start Mgetty on that port to
automatically answer phone calls received by your modem, and display
a login prompt. If all you want to do is allow text-only logins via
modem or from a dumb terminal, this is the only step that you need to
do.
- In the PPP Options page, set the IP address that will be assigned
for connecting clients and any other options that you need. The most
useful is 'Automatically detect PPP connections on serial ports?', which
will cause any client that immediately starts a PPP session after
connecting to skip the usual text-based unix login. However, if this
option is turned on then you should also enable 'Require authentication?'
to prevent untrusted clients from connecting.
- If authentication is enabled, use the PPP Accounts page to create accounts
for all the people that you want to allow login by. For each account,
the server should be set to 'Any' and the valid addresses to 'Allow any'.
