HELP: Configuring PPP on a Basic Debian Linux 1.3.1 System
-----------------------------------------------------------------
ABSTRACT:
The simplest of cnfigurations, a standalone Linux system with an
external modem going across a regular phone line to a well-behaved
ISP cannot get dial-up capability.
Hdw: Pentium 133MHz system (w/ Cyrix 686-type CPU)
Logicode External 56K modem on /dev/cua1 (COM2)
(mouse on 1st serial port /dev/ttyS0 (COM1),
no other serial devices on (COM3 or COM4))
Normal config: Adaptec SCSI adapter, SCSI drives,
SOHO Ethernet card, S3/Verge generic graphics card, ...
Sw: OS: Debian 1.3.1 (secondary os, Windows 95 for connectivity)
Services:
JPS Net (dial-in Internet Service Provider)
attributes: 56K modem support with X2 or 56flex
enforces PAP (Password Authentication Protocol)
well documented technical settings on their webpage
such as DNS numbers, dial-in numbers, etc
Problem: Cannot get pppd(8) configured correctly. The physical
connection works fine.
Steps:
1. Verified kernel support for ppp
2. Matched device /etc/cua1 with the correct serial port.
3. Verified physical connection between modem and serial port.
4. Used Kermit to manually test the connection
(The document PPP-HOWTO is very good about successfully passing
through each step successfully. Unfortunately, it is heavily
biased towards BSD style Linuxes; Debian happens to be ATT Sys5
style.)
Here is where I start to break down. I experimented with ezPPP,
the PPP-HOWTO and help from archived individuals. I'm may be in
a tangle with unnecessary config files or misconfigured files.

# If you are using a STATIC IP number, edit the 0.0.0.0 part of the
# following line to your static IP number.
# 0.0.0.0:
#
# use the modem control lines
38400 <-- I tried using 56800 but pppd didn't like that
modem
# use uucp style locks to ensure exclusive access to the serial device
lock
# use hardware flow control

# create a default route for this connection in the routing table

# mtu 552
# use a maximum receive packet size of 552 bytes
# mru 552
#
# force pppd to use your ISP username as your 'host name' during the
# authentication process
# technically 'user' is bettern than 'name' but ppp understands both
# and 'name' works for CHAP as well.
# name fred <-- my ISP username here
#
# If you need to force PAP or CHAP authentication on the server,
# uncomment the appropriate one of the following lines.
#+chap
#+pap
#
# If you are using ENCRYPTED secrets in the /etc/ppp/pap-secrets
# file, then uncomment the following line.

/etc/ppp/pap-secrets
# This is a pap-secrets file to be used with the AUTO_PPP function of mgetty
# mgetty-0.99 is preconfigured to startup pppd with the login option which
# will cause pppd to consult /etc/passwd after a user has passed this file
# Dont be disturbed therfore by the fact that this file defines logins with
# any password for users. /etc/passwd will catch passwd mismatches.
#
# This file should block ALL users that should not be able to do AUTO_PPP!
# AUTO_PPP bypasses the usual login program so its necessary to list all
# system userids with regular passwords here!
#
# ATTENTION: The definitions here can allow users to login without a
# password if you dont use the login option of pppd!
# The /etc/ppp/options file installed has the login option enabled
# INBOUND connections
# Every regular user can use PPP and has to use passwords from /etc/passwd
* os ""
# UserIDs that cannot use PPP at all. Check your /etc/passwd and add any
# other accounts that should not be able to use pppd!
#guest os "*" -
master os "*" -
#root os "*" -
support os "*" -
stats os "*" -
# OUTBOUND connections
# Here you should add your userid password to connect to your providers via
# pap. The * means that the password is to be used for ANY host you connect
# to. Thus you do not have to worry about the foreign machine name. Just
# replace password with your password.
# If you have different providers with different passwords then you better
# remove the following line.
os * password

Thanks so much for any help. Setting up PPP easily seems to be essential for
any os
these days. Has there been much interest in a Debian flavored FAQ for
configuring ppp?
As I mentioned above, the generic PPP-HOWTO is very good but I coudn't
follow it
because it referrs to many fiiles and directories in a BSD style Linux.
