Subject: Help, pppd fails just after connection
Date: Sat, 10 Apr 1999 23:12:59 -0400
I'm trying to connection to my ISP (Netcom) and the linux pppd keeps
failing. I've read all the usenet discussions and tried several
solutions that don't work.
I'm running pppd version 2.3.5-1. When I use the Gnome-ppp dialer (same
as EZppp), the configuration and scripting is very straight forward.
When I dial out I get the following messages in the debug window.
**********Debug window starts
---NEW CONNECTION---
ATZ
OK
EATZ
OK
ATDT1-781-398-0800
CONNECT 50000 V42bis
bsg-ma-pm1 line 1/8/40
ICG Netcom
login: us,ppp,my_user_name
Password:
PPP session from (163.179.204.130) to 209.110.248.174 beginning...
************Debug window ends
If I have the script look for "ing..." for the last command the dialer
says "connected to ppp" then a couple seconds later a dialog pops up
with a message that the pppd stopped unexpectately. If just let the
debug window go I start getting garabage (which is what is supposed to
happen after the connection is actually made).
Giving up on the easy route I contacted NETCOM for their instructions:
************Netcom Instructions
This document provides all of the necessary information needed to
configure Slackware Linux 3.2 pppd to connect with a NETCOMplete
account. This information has also been verified to work with
Slackware 3.0. We cannot guarantee that these intructions will work
with any other distribution of Linux.
Note: Several scripts are included in this document. They will need
to be copied as is onto the Linux system.
I. Required Programs
In order to establish a PPP connection, Linux needs support for TCP/IP
and PPP in the kernel. Most Slackware pre-compiled kernels with
Network support already have this feature. If the kernel does not have
this support, however, re-compile the kernel. Consult the Linux
documentation for assistance with this step.
A working version of pppd and chat is also required. This comes with
Linux. If using kernel 1.3.21 or greater, however, obtain version
2.2.0 of pppd. It is available via FTP from:
sunsite.unc.edu/pub/Linux/system/network/serial/ppp/ppp-2.2.0f.tar.gz
Both pppd and chat should be placed in the /usr/sbin directory.
II. Create Scripts and Configuration Files
Create the following four files:
Filename Perms Ownership Path of file
------------- ----- ------------ ----------------------
ppp-on: 755 root.root /usr/sbin/ppp-on
chat-netcom
: 640 root.root /etc/ppp/chat-netcom
options: 640 root.root /etc/ppp/options
ppp-off: 755 root.root /usr/sbin/ppp-off
resolv.conf: 644 root.root /etc/resolv.conf
The first file that must be created is ppp-on. This is used to
actually establish the connection. Below is a sample script:
---- Cut Here ----
#!/bin/sh
/usr/sbin/pppd /dev/cua2 38400 \
connect "/usr/sbin/chat -f /etc/ppp/chat-netcom" \
defaultroute modem crtscts lock
---- Cut Here ----
Depending upon which COM port the modem is on, the above script
may need to be edited. Please refer to the following chart:
/dev/cua0 = COM1 /dev/cua2 = COM3
/dev/cua1 = COM2 /dev/cua3 = COM4
Note: The highest speed for a COM port is 38400 bps. In order
to refer to a higher speed, edit the following file:
/etc/rc.d/rc.serial
This file must have the "spd_hi" or "spd_vhi" option when
configuring the COM port on which the modem is connected to.
More
information requiring this step may be found in your Linux
documentation.
The second file that must be created is chat-netcom
.. This is
the configuration file that contains the initialization string
of the modem, the telephone number, username and password.
Below is a sample chat-netcom
file:
---- Cut Here ----
ABORT BUSY
ABORT 'NO CARRIER'
'' ATZ
OK AT+FCLASS=0
OK AT&F&C1&D2
OK ATDT261-4700
CONNECT ''
login: us,ppp,userID
Password: your-passwd
'PPP session' ''
---- Cut Here ----
Note: The string "us,ppp" (without the quotes) must be inserted
in front of the username in the login: field. Without this
prefix, Linux will be unable to establish a PPP connection.
Edit any other entries as necessary. Be aware that we can not
be responsible for any errors that occur due to using the above
script.
The third file is called options. Under most circumstances,
this
file does not need to be modified from its original form:
---- Cut Here ----
domain ix.netcom.com
ipcp-accept-local
ipcp-accept-remote
noipdefault
---- Cut Here ----
The fourth file to create is ppp-off. This is used to terminate
the connection. Below is a sample script:
---- Cut Here ----
#!/bin/sh
DEVICE=ppp0
#
# If the ppp0 pid file is present then the program is running. Stop it.
if [ -r /var/run/$DEVICE.pid ]; then
kill -INT `cat /var/run/$DEVICE.pid`
#
# If unsuccessful, ensure that the pid file is removed.
#
if [ ! "$?" = "0" ]; then
echo "removing stale $DEVICE pid file."
rm -f /var/run/$DEVICE.pid
exit 1
fi
#
# Success. Terminate with proper status.
#
echo "$DEVICE link terminated"
exit 0
fi
#
# The link is not active
#
echo "$DEVICE link is not active"
exit 1
---- Cut Here ----
The final file to create is resolv.conf. This is used to
configure DNS lookups. Below is a sample resolv.conf:
---- Cut Here ----
domain netcom.com
nameserver 199.182.120.203
nameserver 199.182.120.202
nameserver 199.182.120.1
nameserver 199.182.120.2
---- Cut Here ----
At this point, Linux is configured to access a NETCOM Account. Login
as root and run the ppp-on script to establish the connection. When
finished with your PPP session, run the ppp-off script.
***********End of Netcom instructions
I follow this to the letter (except for username and password). the
ppp-on script dials and sounds like it connects (I don't know how to
echo to the terminal) but then the connection is not active. Seems like
I am missing some very minor element here in my setup. Anyone out there
in TV land who can help (very frustrated)?
thanks,

Lemme guess, you updated Red Hat 5.x to the 2.2 kernel? They provided
updated packages that will fix the problem, they're in a 2.2-upgrade
directory or something like that.

Date: Sat, 10 Apr 1999 19:39:17 -0700
Folks:
I have spent enough time on this that I am willing to buy someone a CD of
their
choice to solve it. I have read all the HOW-TO's and tried all suggestions
offered so far - no luck.
Please see end of the mail for 'reward' conditions.
Summary of my problem
=====================
- Can successfully ping my dns server but I ping anything else there is no
response.
- Name resolution works: if I type in redhat.com, its IP address will show
up.
- If i remove the default route option from pppd then, i get "network not
reachable"
when I try to ping anything other than my name server.
All relevant information and outputs are given below.
System configuration
====================
- Direct modem dialup connection.
- There is an ethernet card on the NT side of my system but it is not
configured under linux.
- There is an adaptec Ultra2 scsi card in system which not recognized or
used
via linux. I am using an IDE drive.
- Running Redhat 5.2 out of the box on a Dell NT XP350, booting from a
floppy.
- From the NT side I can successfully operate PPP over same modem and IP
addresses.

absolutely.... i have a 486sx25 with 8mb and two 3c509 cards and it acts
as a router / firewall for a 4 computer lan (not including the router)
connected to the Internet via an ADSL line...
And you don't even need a harddrive. Two projects
http://www.linuxrouter.org and http://edge.fireplug.net are Debian
redistributions geared to boot off of a floppy and reside in RAM. (Yup,
RAM based filesystem and all that speed!!)
After you get the right ethernet drivers onto the floppy (for
LinuxRouter, anyway), it includes everything you need.

I take it that the third com port is an add-on? BTW: this should have
nothing to do with the fact that a modem happens to be connected to
it.
The fact that linux is initially assigning IRQ 4 is by convention;
Coms 1 & 3 got IRQ 4 while Coms 2 & 4 got IRQ 3. Problem? Well,
generally, yes. However, because the system only has so many
interrupts, and a majority of those are taken up with petty things
like keyboard and mouse, they couldn't assign them arbitrarily. Also,
who uses more than 2 serial ports? It goes along with "who's ever
going to need more than 640k of memory?"
Linux is not assigning this with some deep-founded knowledge; it is
making the assumption. To correct it (and this is quite easy), just
issue the setserial command such as
setserial /dev/ttyS2 irq 7
That's all.
You may also want to make sure that the I/O port is set to 0x03e8,
which is the standard for Com3. If not (if not indeed, win95 is
arbitrarily calling it Com3), find out what it is and change the above
command line to
setserial /dev/ttyS2 irq 7 port 0x3e8
replacing 0x3e8 with whatever the port is (0x3e8 in hex or 1000 in
decimal). If it is in fact 0x3e8, don't try to mess with it.
If this isn't done, and linux continues to use IRQ 4 for a device that
is trying to use 7, then the device will not work correctly. In the
case of a serial port, it will not perform (much past a line or two at
most).

It may not be a conflict just that your modem is not using the IRQ you believe
it is given the COM port (CUA1-4) its assigned to. Once you find out what the
problem is you can use setserial to change the IRQ of the serial port. I had
similar problem and since I had a dual boot linux/win95 PC was able to
determine that the modem in COM port 3 was using IRQ 5 instead of 4 from
windows. I then used setserial to correct the problem.

It will be loafing acting as a firewall/router for a 3 or 4 PC lan.
You'll probably need to run IP masquerading for your local network.

Is the network card they give you an ISA card or PCI (10 or 100Mbps). Because
my linux box is an AT i486 (no PCI)

Subject: 2 Ethernet Cards - IRQ/Address Conflict? Help!
Date: Sun, 11 Apr 1999 23:58:47 +0800
My RedHat installation was fine with one ethernet card.
I just installed a second and added a file ifcfg-eth1.
On reboot the system hangs. Remove the card and its fine.
Both cards work fine under Windows.
Neither card has jumpers and both seem to be using IRQ11.
They use different addresses (6400 & 6800).
Is there anything I can do to fix this other than buying a new card with
jumpers?
