1. on the machine that will ultimately be making the call, set up a dial
out script with chap or pap, or both :-)
2. Install sudo.
3. Assuming your remote system is called "fred", make sure that
"sudo pppd call fred" works properly.
4. Create a user for fred. Now you can have it's .bash_profile consist of
sudo pppd ......
logoff.
5. The more creative types, can even not allow incoming calls at all.
put in your .procmailrc file:
:0:
* ^Subject: CALL-ME
| sudo pppd .....
Sending yourself the appropriate email gets you your call back. Although
I would have it start a script that does a little more checking and
possibly a sleep command to allow your calling system to hang up.
If you could find an SMS->EMAIL gateway, you could start the call with
your cell phone.
If a faster connection is needed, Dynamode sells an ISDN T/A for about
$100, that looks and acts like an external modem. You just plug it into
your serial port and use it as if it were a 64k (or 128k) hayes
compatible modem and you can make ISDN data calls to many places outside of
Israel.
