You should not use that. That are to be called by higher level scripts.
You should be using /etc/ppp/scripts/ppp-on and ppp-off (perhaps yours are
named just pppon and pppoff), and they set up everything and call ifup-ppp.
If you use that you just have to setup options in /etc/ppp/options.
One other issue is who is allowed to dial. I think it can be done cleanly
through the usermode tools, but I never get involved with them. There
are two ways to do that:
- Make the modem device world writable: chmod 666 /dev/ttyS1 (not 755, you
don't have to EXECUTE(run) the device, just be able to write to it in
addition to reading, to configure it and send init strings).
- Make /sbin/pppd or /etc/ppp/scripts/ppp-on (off) suid (chmod +s .....)
I think the first way is less 'unsecure'. I now have a cable connection,
so I don't remember if both things were needed.
