pppd: Debug a LCP conversation - LCP translator needed
Hi
I'm running a ordinary pppd-CallIn-Server on a Debian Squezze server. Any Linux client has no problem to call in an to establish a connection to this pppd-server.
Now I got an inconvenient embedded device which has to connect the server. Without any success. The PAP-Login fails. It fails somewhere during the LCP conversation. I have no idea about LCP (google also doesn't know that much). Could some one help met to debug the LCP conversation?
PPPD will be started with
Code:
08/14 10:24:24 yS0 calling login: cmd='/usr/sbin/pppd', argv[]='pppd auth -chap +pap login debug'
Then the LCP Conversion starts:
Code:

Any ideas what goes wrong? Unfortunately the embedded device has no log about the session.
thanks for any suggestions. |
