PPP error - LCP: timeout sending Config-Requests

PPP error - LCP: timeout sending Config-Requests

Post by Jim Ostro » Mon, 02 Nov 1998 04:00:00



I am using RH5.1

Hope someone can help with the following error message
from /var/log/messages. I can't find any LCP: timeout
error fixs in the PPP-HOWTO, or newsgroups...

My modem works fine under WIn95, so I'm thinking its
not a hardware/configuration problem?

I invoke pppd from the control panel, Network
connections, interfaces, ppp0 "activate" button.

Modem dials up and connects, establishes serial
connection, then dies.

Here is the messages log:

This may well be the problem, a carriage return (^M) which is send
by the chat expect/send <CONNECT ''>.  This sometimes will confuse
the ISP and prevent it from starting ppp on it's end.  You can use
<CONNECT \\c> or perhaps <CONNECT \\d\\c> instead.  "man pppd" to
find out about \c and \d.

: Oct 31 11:32:45 localhost pppd[990]: Problem: all had bit 7 set to 0

The "not 8-bit" clean usually means a text program is running at the ISP,
not ppp.  For more about this read the PPP-HOWTO, it may be in your linux
directory /usr/doc/howto.

PPP error - LCP: timeout sending Config-Requests

Hello,

     I also have the same problem. I am using MS-CHAP to connect to a
Windows NT server. I already had read PPP HOWTO and README.MSCHAP80
found in ppp distribution and made the necessary changes to the
different scripts to no avail. Please refer to my other posting in
comp.os.linux.networking for details. I still cannot get it working.
If you were able to able to solve this problem, please let me know.

PPP error - LCP: timeout sending Config-Requests

Post by Tom Savag » Wed, 11 Nov 1998 04:00:00


Greetings,

I have had similar problems which were caused by an irq conflict somewhere
in my system.  The default irq for com 3 (cua2) in RH 5.1 is 4; this
produces a snail-paced transfer.  When I issue the command    "setserial
/dev/modem irq 2"  I get expected transfer speeds.  In my case the LCP
timeout was caused by lack of communications over the link.  Hope this
helps.

1. Rehat 4.0 ppp: "LCP: timeout sending Config-Requests"

I'm recently done a fresh install of Redhat 4.0 and am try to
configure ppp to dial my ISP.  I've read posts regarding this error
that point to the ISP as the cause, but there are users on my provider
successfully connecting with pppd under Redhat (I've asked them but
haven't found my answer).  Anyways, It seems like I'm sending my
username/password successfully, but I'm getting a "timeout sending
Config-Requests" error on completion of my script.  

Anyone seen a similar error or have any advice on how to successfully
connect?

Thanks,
Pat Dalzell

My /etc/ppp/options -
connect /etc/ppp/chat
/dev/cua2
bsdcomp 9,15
mru 296
crtscts
defaultroute
lock
modem
noipdefault
passive

/etc/ppp/chat -
#!/bin/sh
NUM=1111111
USER=patd
PASS=password
/usr/sbin/chat -v "" ATDT$NUM ortmaster "" ogin: $USER word: $PASS
180

Expecting "ortmaster" is strange, but it seems to be the only way I
can get to the authentification step without an alarm.  Also waiting
for the 180 outputs the "Packet mode enabled" line in
/var/log/messages - this *seems* to be a good thing and I hoped it
would make good evidence without interfering with the logon process.
I get the same error without waiting for it.

Anyhoo, here's the result from /var/log/messages -
