PPP LCP: timeout

I'm using earthlink with slack 9.1 and I have problem with using PPP-go,
command, I get following message,

Connect: ppp0 <--> /dev/modem
LCP: timeout sending Config-Requests
Modem hangup
Connection terminated.

with verbose LCP:... line repeats about 15 to 20 times

I believe up to chat & authentication is successful. Thing is I'm able to
make connection by using Kppp... strange
Now I need to connect to internet from commandline. Help me out to
troubleshoot, what possibly causing this LCP msg to appear, and what's so
difference between kppp and PPP package except kppp is GUI?

You probably need to enable more logging to see what is actually
happening. Kppp handles its own authentication. But for a commandline
script, I suspect that you would need to properly configure
/etc/ppp/pap-secrets and/or chap-secrets. Otherwise pppd does not know
what to use for username/password.

Where in Slackware 9.1 would the "PPP-go" be located? I don't think
it exists.

Frankly, you really need to give more complete information, ask better
questions, and stop using ... so much. Try reading

good ole Earthlink. Watch what you are using for a username.

OK, the key is often the authentication. First, in _MOST_ cases, you do
not want to be looking for a login prompt. Earthlink _MAY_ sometimes be
an exception, because they are using contracted points of presence (you
posted from 4.249.207.131, which is a Level3.net address), but that is
now (generally) handled by them having you use a username that contains
'@earthlink.net' so that the peer knows you are an Earthlink customer,
instread of their own.

You are going to wind up with _SOMETHING_ that looks like this:

[compton ~]$ cat /usr/local/bin/dialin
#!/bin/bash
exec /usr/sbin/pppd connect "/usr/sbin/chat -f /etc/ppp/dialscript" \
defaultroute lock noipdefault modem nodetach /dev/modem 115200 crtscts \
user '(E-Mail Removed)'
[compton ~]$

There must not be anything after the \ in those two lines.

[compton ~]$ cat /etc/ppp/dialscript
ABORT BUSY ABORT 'NO CARRIER' "" AT&F1 OK ATDT2662902 CONNECT \d\c
[compton ~]$

Set up a _PAIR_ of files named /etc/ppp/pap-secrets and chap-secrets that
have the username and passowrd in the form

'(E-Mail Removed)' * 'p42Sw0rD~'

Notice how I'm quoting each variable, to protect any strange characters
each may contain. Obviously, you need to replace the username , password,
and telephone number as required. Also, the AT&F1 is used by USR modems,
Others may want AT&F0. Unless you really know what is in the modem's
NVRAM, "ATZ" is _NOT_ an acceptable init string. See your modem manual.

[compton ~]$wc /usr/local/bin/dialin /etc/ppp/dialscript
/etc/ppp/pap-secrets
4 19 169 /usr/local/bin/dialin
1 11 67 /etc/ppp/dialscript
1 3 22 /etc/ppp/pap-secrets
6 33 258 total
[compton ~]$

I dunno, maybe about 100K of bloat?

:~$ whereis ppp-go
ppp-go: /usr/sbin/ppp-go

there you go and "ppp-on" is sym link of it

I used 'debug' option in 'options' file
I don't know it says auth is success, LCP is requesting something after
authentication. I think my ISP isn't responding with ack

Is this mean ISPs sharing points where you dial in, and distinguish each
users by portion of username? And what do you mean by not looking for a
login prompt? -_-a;; (in Script file?)

Thanks for the link, I gained much knowledges, one of them is
there're so many variations of authentication methods, many more than just
Script,PAP, and CHAP

Very similar to what I configured, except few additional options I have in

I really dont' get it, kppp supposed to use pppd, too. Gui version works
but script doesn't. I tried with "lcp-max-configure" and "lcp-restart"
options, no luck. It's like answer is right in front of me but I can't
catch it. I really need know how to log more than 'debug' option. I need
more information

Got it!
Problem was pppscript
Using AT&F1 instead of AT&F0 fixed the trouble(I'm using USR external).
Still wondering that's reset modem command, how did it effected to
negotiation process

Thanks very much!! You're a life saver!

With most ISPs, authentication isn't done _directly_ on the box that
you are dialing into. Instead, there is an authentication server that
is isolated for security, and it has all of the usernames and passwords.

On the box you are dialing into, it looks at the username, and MAY make
a decision which authentication server to ask. Thus, if you dial in to
Level3.net, there server will see your '(E-Mail Removed)' username
and pass it (and the password you sent) to the Earthlink authentication
server. Another person from Compuserve or Prodigy, or MSN.net (all of
which use contracted service points), would have a different type of
username, and authentication data is passed to the appropriate
auythentication server. The remote authentication server then replies to
the box you are logging in on, with a Success or Fail message, and
things continue from there. In this way, Earthlink (or Compuserve, or
Prodigy, or MSN) keeps their authentication data in one place, rather
than duplicated onto the servers at every place where you can dial in.

>And what do you mean by not looking for a login prompt? -_-a;; (in
>Script file?)

If you look at the documentation that comes with pppd, or in the PPP-HOWTO
(or ISP-Hookup-HOWTO), you will see the chat script looking for a login
prompt. For example:

#!/bin/sh
#
# This is part 2 of the ppp-on script. It will perform the connection
# protocol for the desired connection.
#
exec chat -v \
TIMEOUT 3 \
ABORT '\nBUSY\r' \
ABORT '\nNO ANSWER\r' \
ABORT '\nRINGING\r\n\r\nRINGING\r' \
'' \rAT \
'OK-+++\c-OK' ATH0 \
TIMEOUT 30 \
OK ATDT$TELEPHONE \
CONNECT '' \
ogin:--ogin: $ACCOUNT \
assword: $PASSWORD

That's the file 'ppp-on-dialer' from the pppd package. Notice how this looks
for something that says 'ogin:' (meaning it will accept 'Login:' or 'login:'.
This got you into a shell login on the server, and that should have started
the pppd application there. Unfortunetly, when Microsoft invented the
telephone (or was it the internet) in 1995, their program wouldn't handle
such a scripted connection. Most ISPs follow the demands of Microsoft, and
changed the way their servers are configured, so as to use RFC1334
authentication (PAP).

>Very similar to what I configured, except few additional options I have in
>'options'

I've been using that script for about 8 years now.

>> I dunno, maybe about 100K of bloat?

Yes, kppp is a replacement for /usr/sbin/chat - amoung other things. It's
just a very bloated front end or 'wrapper' application.

Bill Unruh's web page (the ubc.ca/ppp-linux.html web page I referenced)
tells all about that.

THAT'S why I always recommend reading the modem manual ;-)

from the on-line help available from many USR modems

&Fn n=0 Load Factory 0, no FC
n=1 Load Factory 1, HW FC
n=2 Load Factory 2, SW FC

FC = flow control. The data was getting corrupted because you were
not using flow control.

So MSN, Earthlink, Compuserve etc might share same local number for dial
in. wow that's really cool way to handle business

got it. remembered to expect just 'connect' for PAP, and CHAP in
script. Didin't know MS changed to their way with their influence in

Really appreciate experts like you are around in usenet, when getting
right answer to solve vague problems Thanks!!!
