PPP receives bad frame msg and times out sending Config-Request

PPP receives bad frame msg and times out sending Config-Request

Post by ashi.. » Mon, 16 Nov 1998 04:00:00



Trying to connect to the ISP pppd. Can connect thru NT4.0 to the same
ISP.
Can connect thru  linux pppd to another ISP. Below is the session log. I
get a "frame with bad fcs" message. Any help would be appreciated.

Does the pppd at the ISP have to support Linux. Or can one make an
assumption that if pppd for NT4.0 is supported, it should  compatible
with linux too.

TIA

and then the session terminates
Added ipcp-local-access and ipcp-remote-access to the options scripts.
Did work 2-3 times and then fails again all the time.

Try playing with the pppd asyncmap option.  asyncmap 0 first, then
asyncmap a0000, asyncmap 20a0000 .  If an option escape <xx,xx,...>
is present, try removing it.  If this fails, increase the verbosity
of the logs in your posts.

Sometimes not but usually yes.

There are no such options for any pppd that I know about.

Peculiar, if true.  Maybe the non-options you added contributed to this.

1. PPP times out during send-config request

I am trying to connect to my ISP. I get the following mesage using PPP
for RH5.2
Any ideas or inkings? The issue seems to be a  time out "timeout sending
Config-Requests".  Not sure what to do?

Have attached the debug log from pppd

I can connect to another ISP without problems. So does it have to do
with the PPPD the ISP end?

TIA
