Hi,
This sort of thing (22 Seconds) often happens when a remote device is attempting to
authenticate say a Cisco router. Linux is often one I come across another is when
logging into a group of routers then using RDIUS or similar to allow access.
The remote device attemts to authenticate the called router but it does not
necessarily reply the way the remote device wants to see it. In a number of cases it
is easier to have the called device to the 'chap' authentication and not have the
remote device do the authentication as well (no auth in Linux ppp setup) don't add the
'ppp auth chap' in the dialer of the calling router. This of course assumes you are
only interested in a remote connection calling to central site and the central site
being the device interested in controlling security.
Debug PPP neg shows the attempt.
Just a thought,
It is one I have come across on several occasions.
