Sounds like your problem is that you need to properly configure your
ports to handle dialin. After that you should be able to proceed with
setting up a PPP server.
I have recently set up a PPP server on FreeBSD 2.0, so I should be able
to help you through most of it. It's not always obvious what you need
to do, so I'll review the steps as I remember them.
[ note - I am _not_ a UNIX guru... there may be (and likely are) better
and more efficient ways of doing this. It works for me. YMMV. ]
* Configure your ports. I use a script /etc/rc.serial, which is called
by rc.local - this sets up the default configuration of my ports:
|#!/bin/sh
|
|# port 0 is serial mouse
|
|# port d is 14.4 modem on private line
|for port in d
|do
| stty -f /dev/cual0${port} crtscts speed 57600 cs8 -parenb > /dev/null
| stty -f /dev/cuai0${port} crtscts speed 57600 cs8 -parenb > /dev/null
| stty -f /dev/ttyld${port} crtscts speed 57600 cs8 -parenb > /dev/null
| stty -f /dev/ttyid${port} crtscts speed 57600 cs8 -parenb > /dev/null
|done
|
|# ports 1-c are 28.8 modems on main hunt group
|for port in 1 2 3 4 5 6 7 8 9 a b c
|do
| stty -f /dev/cual0${port} crtscts speed 115200 cs8 -parenb > /dev/null
| stty -f /dev/cuai0${port} crtscts speed 115200 cs8 -parenb > /dev/null
| stty -f /dev/ttyld${port} crtscts speed 115200 cs8 -parenb > /dev/null
| stty -f /dev/ttyid${port} crtscts speed 115200 cs8 -parenb > /dev/null
|done
* Add the ports to /etc/ttys with entries like the following:
|ttydd "/usr/libexec/getty dial.57600" vt100 on
dial.57600 corresponds to an entry in my /etc/gettytab. You won't have
one unless you create it. Use whatever is approprate for your modems.
Make sure you use ttyd* devices, _not_ tty0* or cua0*.
* Configure your modems to auto-answer. If you are using Hayes
compatible modems, use 'ATS0=1&W'. Your modems may require other
configuration, but I can't help you with that unless I know what you
have. In general, make sure your modem does RTS/CTS flow control,
locks the baud rate, properly responds to DTR, and asserts CD properly.
* Do a 'kill -HUP 1' to force init to re-read your /etc/ttys file and
spawn new gettys.
You should be able to dial in to your machine now. Try logging in and
make sure that everything is working fine.
Once that's working, you can set up your ppp server stuff. Your next
steps will depend on whether or not you want to do dynamic or static
address assignment. I assume that you'll probably want to do static -
it's easiest, and since there's only two users it's probably best. (I
have configured mine for dynamic allocation - I can help with that's what
you want to do).
Set up accounts for each PPP login. Set the shell to /usr/libexec/pppd.
Set up system-wide options in /etc/ppp/options (refer to the pppd man
page if you need help - if you can give me more details about what you
want, I can give you more guidance.
In the each home directory, set up a .ppprc that contains the local and
remote IP address in the following format: local_ip:remote_ip. Use
dotted quads.
If you are not running routed or gated, you may need write a script so
that your system will discover the routes. Don't run routed unless you
have no other options.
For the freebsd-questions people: If there's enough interest, I'd be
willing to contribute my experience setting up dynamic IP allocation to
a FAQ or HOWTO.
