linux, PPP, AT&T Worldnet - looks like PPP does not start???

Post by Elizabeth Larrey Konstantino » Mon, 19 Jul 1999 04:00:00



I am using PPP 2.3.8, kernel 2.2.10 with AT&T WorldNet. Linux installation
is SlackWare 3.1
I have a /etc/chap-secrets file set up exactly as the Wurd page for
WorldNet/Linux instructs.

here is my script:



connect '/usr/sbin/chat -t 45 -v ABORT BUSY "" \
ATDT9700304 CONNECT ""' \
/dev/ttyS2 38400 debug noipdefault modem \
defaultroute kdebug 25

resorv.conf is set up as wurd instructs also. It looks like I never get to
authenticate myself and ppp on the isp side never starts.
It looks like I keep sending LCP ConfReq's -- does that mean that my PPP is
asking the ISP to authenticate itself? I did specify the 'noauth' option
(see the script).
Can the linux installation (libraries, etc...) be too old??
The modem works (I tried dialing in minicom). PLEASE HELP!

Thanks
Andre

linux, PPP, AT&T Worldnet - looks like PPP does not start???

Post by Ian Brig » Mon, 19 Jul 1999 04:00:00




:connect '/usr/sbin/chat -t 45 -v ABORT BUSY "" \
:ATDT9700304 CONNECT ""' \
:/dev/ttyS2 38400 debug noipdefault modem \
:defaultroute kdebug 25

It may be possible to simplify these a little.  Bill Unruh's "How to hook
up PPP" is a good step-by-step guide -- at
http://axion.physics.ubc.ca/ppp-linux.html .

:It looks like I keep sending LCP ConfReq's -- does that mean that my PPP is
:asking the ISP to authenticate itself?

No, the ConfReq is simply an attempt to open negotiations with the ISP.
It looks like your ISP never responds, probably because it's still waiting
for something else.  Bill's guide may help you to clear things up.

Good luck.

I see in the message below at 12:08:59 ("Name and password pair incorrect..
Please sign-on:")
In the Worldnet dialer unix variant newsgroup, someone mentioned that you have
to configure chat to
look for (on:) from the sign-on: instead of the default (in:). I added on:
".$NAME." to the chat part of the script. which
was on the AT&T WURD site.

$command="/usr/sbin/pppd name \"".$NAME."\"".
                   " -d connect \'/usr/sbin/chat -t 45 -v ABORT BUSY

Post by Andre Konstantino » Mon, 19 Jul 1999 04:00:00


I am using PPP 2.3.8, kernel 2.2.10 with AT&T WorldNet. Linux installation
is SlackWare 3.1
Changed my script to the following:

/usr/sbin/pppd /dev/ttyS2 57600 noauth lock crtscts modem noipdefault \

connect '/usr/sbin/chat -v -t 120 -r /etc/ppp/connect-errors \
REPORT CONNECT ABORT BUSY ABORT "NO CARRIER" "" \

The result seems "better" than before - in that I no longer get bad fcs
frames... but what is happening here?
Please Help!

The peer cannot hear you.  The peer is probably using very buggy
software.  Try setting asyncmap to 0x000a0000 instead -- most of the
bad implementations get along better with that particular value.

It looks like the remote is not seeing anything you send to it.
Even though you are ack-ing its requests, and sending some requests
of your own, the remote never seems to see what you are sending, since
it does not send ack nor nak to your requests, and it keeps repeating
the same ConfReq of its own.  Why don't you try turning on ppp's
kernel debugging messages, and see what is happening to the stuff
you are trying to send ?

1. ppp & chat scripts for AT&T's worldnet service???

Hi,

I am able to dial up to my ISP (AT&T's worldnet) but I have problems
starting my ppp & chat scripts. (My kernel is compiled with pppd
support). I suspect that my login and password pair is not get accepted.
Note that I can connect fine  through NT. I am new to linux so I don't
really know how to troubleshoot things.

I would greatly appreciate if someone could email me his ppp and chat
scripts for connecting to AT&T worldnet or any other ISP. Should I exit
minicom without reseting the modem before I execute the scripts? I am
using RH linux 4.2.

Thanks a lot,
