Description of most natural method:
RECEIVING INCOMING PPP CONNECTIONS (Method 1)
To handle an incoming PPP connection request, follow these steps:
1. Make sure the modem and (optionally) /etc/rc.serial is configured
correctly.
o Use Hardware Handshake (CTS/RTS) for flow control.
o Modem should be set to NO echo back (ATE0) and NO results string
(ATQ1).
2. Edit /etc/ttys to enable a getty(8) on the port where the modem is
attached. For example:
ttyd1 /usr/libexec/getty std.38400 dialup on secure
Don't forget to send a HUP signal to the init(8) process to start
the getty(8).
# kill -HUP 1
3. Edit /etc/gettytab to enable a pp capability to the same terminal
class as your /etc/ttys entry. In our example it is ``std.38400'':
std.38400|38400-baud:\
:pp=/etc/ppp/login:im=\r\n:\
:np:sp#38400:
/*
* I really show here the ``im'' capability too, thats for short login
* prompt, just ``login:''.
*/
4. Create a /etc/ppp/login executable script with the following
contents:
#!/bin/sh -p
/usr/bin/mesg n
/bin/stty -tostop
exec /usr/sbin/ppp -direct
/*
* Do we really need that mesg and stty commands ?
* I noticed, that without ``/bin/stty -tostop'' ppp server will not exit
* after hangup.
*/
(You can specify a label name for further control.)
Direct mode (-direct) lets ppp work with stdin and stdout. You can
also use pppctl(8) or telnet(1) to connect to a configured diagnos-
tic port, in the same manner as with client-side ppp.
5. Optional support for Microsoft's IPCP Name Server and NetBIOS Name
Server negotiation can be enabled use ``enable msext'' and ``set ns
pri-addr [sec-addr]'' along with ``set nbns pri-addr [sec-addr]'' in
your /etc/ppp/ppp.conf file.
