Hi,
You're correct. The linux machine should not REQ the compression
schemes that were REJected.
> (This is a PPP related question.)

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

> Linux ---> CCP conf request (with 3 compression schemes, A, B and C) --> =
> PPP server
> Linux <-- CCP conf reject (schemes, B and C) <-- PPP server
> (That is, the PPP server picked the compression scheme A, and rejected =
> the rest.)
