(This is a PPP related = question.)

It seems the RedHat Linux 7.2 PPP = client does not=20 work with the FreeBSD 4.5 PPP server in the CCP (Compression = Control=20 Protocol) negotiation. Briefly, the problem looks like the=20 following:

Linux ---> CCP conf request (with 3 = compression=20 schemes, A, B and C) --> PPP server

Linux <-- CCP conf reject (schemes, = B and C)=20 <-- PPP server

(That is, the PPP server picked the = compression=20 scheme A, and rejected the rest.)

Linux ---> CCP conf request (with 3 = compression=20 schemes, A, B and C) --> PPP server

Linux <-- CCP conf reject (schemes, = B and C)=20 <-- PPP server

(repeat may times without progress.)

It seems the Linux client did not follow the PPP protocol and = ignored=20 the CCP reject messages.

The correct message exchange should look like the = following:

Linux ---> CCP conf request (with 3 = compression=20 schemes, A, B and C) --> PPP server

Linux <-- CCP conf reject (schemes, = B and C)=20 <-- PPP server

---> CCP conf = request=20 (scheme A) --> PPP server

<--- CCP conf = ACK=20 (scheme A) <-- PPP server

Comments?

P.S. I am using PPPoE for the=20 testing.
