Here is my ppp.conf file that contains notes about configuring dial
in connection. Follow imbedded instruction to enable dial in
connections.

# /etc/ppp/ppp.conf File for dial out modem to ISP and Dial in modem
for
# connection to this FBSD system.
# Written by Joe Barbish 12/10/2001
#
# This is a working ppp.conf file I use to dial in to my ISP and to
connect
# my Win98 box by dialing in to this FBSD box and accessing the
internet.
# There are options in this ppp.conf file that I do not use, But
present them
# here for you to turn on by un-commenting the statements to meet
your needs.
#
# For Nic to DSL configuration see www.daemonnews/200101/pppoe.html
#
# This ppp.conf documentation is based on a fresh install of FBSD
4.8 with
# all file content as delivered with no user changes.
#
# NOTE Any FBSD documentation that says that the physical modem has
to have
# it's default options profile set to, NO command echo ATE0 and NO
results
# string ATQ1 and saved to the physical modems onboard non-volatile
memory
# (NVRAM) or any references to using programs tip, kermit, mgetty,
or minicom
# to perform the dial function is obsolete and out dated as of FBSD
4.0.
#
# Setup Instructions.
# Note steps 4 through 7 are only for dial in setup.
# 1. Recompile kernel and change pseudo-device tun 1 to tun 4
# GENERIC kernel defaults to 1 and you need 1 tun device for each
com port
# 2. Add gateway_enable="YES" to /etc/rc.conf so dialin connection
can gain
# access to internet.
# 3. Since a private internal IP address numbering scheme is used
for IP
# addresses behind this FBSD box the -nat option must be included
on the
# ppp command that starts the ppp task to dial the ISP.
# NAT = Network Address Translation. Changes your private
internal IP
# address to your public IP address that you get from your ISP
for
# outbound messages and does the reverse for inbound messages.
# From the command line example ppp -background -nat dialisp
# 4. Using root create file /etc/ppp/ppplogin
# Create file ppplogin with following 2 statements
# #! /bin/sh
# exec /usr/sbin/ppp -direct incoming
#
# incoming is the section label name in ppp.conf to be processed
when
# ppp is started by this script's exec command.
#
# This script will be launched by getty when it detects a ppp
dialin
# connection attempt. Program ppp belongs to group network, so
you have to
# change file ppplogin group to network and it's permissions to
read/write
# for the owner, read/execute for group, and none for everyone
else.
# chgrp network ppplogin assign file ppplogin to group
network
# chmod 650 ppplogin set permissions
# 5. Change the default section of /etc/gettytab file for automatic
ppp
# recognition by specifying the pp capability. Add following
# :pp=/etc/ppp/ppplogin:
# 6. Edit /etc/ttys to enable a getty on the port where the dialin
modem
# is attached. com2 = ttyd1 find statement like this
# ttyd1 "/usr/libexec/getty std.38400" dialup off secure
# Change off to on to activate. Verify line speed is correct
(std.38400)
# This value is defined in /etc/gettytab. After saving edited
results
# issue kill -1 1 command to spawn getty. Use ps ax to show
active tasks.
# 7. cp /usr/share/examples/ppp/ppp.secret.sample
/etc/ppp/ppp.secret
# Edit /etc/ppp/ppp.secret file adding the ID and password for
each user
# that is authorized to login to this FBSD box using dialin
modems.
# 8. TESTING Issue command ppp -background -nat dialisp to test
configuration
# Use commands ps ax to see task list. ifconfig -a to see if tun
is running
# netstat -ir to see routing. /var/log/ppp.log to view ppp log
events
# ps ax to get ppp -background task number & kill -1 number to
terminate.
# 9. Once you are done with testing, make functions permanent.
# Dial ISP at FBSD bootup. Add following to /etc/rc.conf file
# ppp_enable="YES"
# ppp_mode="ddial"
# ppp_profile="dialisp"
# ppp_nat="YES"

Subject: Dialin problem

Hi, if anyone has done dial-in service before
i am having is that my modem does pick up the phone when i dial in,
and the two modems establish a connection, but the OS does not do
anything there is no login prompt, i was able to send data directly
to the port and see it on the other computer with command: echo
"Hello" > /dec/cuaa0, Also i read that if getty completes the open
port process then it changes from ?? in the PS screen to something
it does not, so i am assuming that getty doesn't realize that the
connection has been established, any ideas?
