Hello,
I'm trying to set up a pppd connection from my linux-pc to an office computer
running under Windows NT. I'm using SuSE Linux 6.3 (kernel 2.2.13). As a
guideline for setting up pppd (version 2.3.11) I've used the howto at
http://www.suse.de/de/linux/docu/ppp_nt/PPP_NT_HOWTO.html
which is written in german:-)
But I will present all necessary information here (I hope).
For starting the ppp-connection, I've written the following script:
---------------------------------------------------------------------
#!/bin/bash
# Aufbau einer PPP Verbindung
# zu einem Windows NT Server unter Verwendung des CALLBACK-Modus
phone="callback <my-number>"
# This works:
/usr/sbin/pppd call my-office connect '/usr/sbin/chat -v -f /root/bin/win_nt.chat'
lock $phone -detach
# If the callback fails, exit (sometimes the phone line is busy):
ret=$?
if [ $ret -ne 14 ]
then
echo "Exiting (pppd exited with "$ret") ..."
exit 1
fi
# This fails always, but I don't know why:
/usr/sbin/pppd call my-office connect '/usr/sbin/chat -v -f /root/bin/win_nt_cb.chat'
lock -detach defaultroute
---------------------------------------------------------------------
The file /etc/ppp/peers/my-office contains the following options:
---------------------------------------------------------------------
/dev/modem
115200
crtscts
<ip-address-of-office-net>:<ip-of-office-pc>
defaultroute
debug
modem
name Administrator
remotename office-pc
---------------------------------------------------------------------
The problem is, that the second call to pppd fails with the message
pppd[516]: LCP: timeout sending Config-Requests
In other words, I can connect to the office-pc with the callback option.
The office-pc calls me back and the chat script "win_nt_cb.chat" works as
expected. It simply waits for a RING, sends ATA, and waits for the CONNECT
message. Therefore, I think that my setup should be correct, or?
This error can be found in the following logfile:

Ok, I've read the pppd-FAQ, found the last question and changed the
connect option to
init "/usr/sbin/chat '' ATZ OK ATS0=1 OK".
But the result was the same as with my script.
My next test was to include the options "silent record /tmp/pppdump.log" to
the second call to pppd.
The output of pppdump -p /tmp/pppdump.log is:

As you can see, there are ppp-packets coming from the office-pc. But
my pppd does not recognize them!
My question is: what's wrong? Or: what can I do to get more informations
about my problem?
Please reply to my E-Mail adress, as I'm not listening to the linux-ppp
mailing list!
Thanks in advance
Torsten
