LCP: timeout sending Config-Requests (PPP problem?)

LCP: timeout sending Config-Requests (PPP problem?)

Post by Casey & Paul Youn » Sun, 31 Dec 1899 09:00:00

Hi all,

I am having a problem getting my dial-up account to work from my Linux
(Redhat 6.1) box.  I have just installed an ActionTec modem (advertised to
work with Linux) and got all the scripts set up to dial my ISP.  I even get
to the point of seeing that ppp0 is connected to /dev/ttyS2.

However, after about 60 seconds (the TIMEOUT specified in
/etc/ppp/ppp-on-dialer), my modem hangs up with a message about LCP timeout
on sending the Config-Requests.

I even modified the ppp-on-dialer script to contain "noauth", thinking that
my modem was expecting PAP or CHAP authentication - no luck - it still times
out on the Config-Requests.

I also verified that kerneld is running (saw that in a PPP document on the

I am including the outputs/contents of several items that I thought would be
necessary.  Any help would be appreciated.  I can provide more information
if necessary. (such as the ppp-on and ppp-on-dialer contents)

Please be sure to include my home e-mail on your response - I don't get to
check the newsgroups too often.

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

My /etc/ppp/options -
connect /etc/ppp/chat
bsdcomp 9,15
mru 296

/etc/ppp/chat -
/usr/sbin/chat -v "" ATDT$NUM ortmaster "" ogin: $USER word: $PASS

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 -
