Microsoft Call Back Configuration Protocol.
|
||
|
|
by Pedro Roque Marques
|
||
|
|
(updated by Paul Mackerras)
|
||
|
|
|
||
|
|
The CBCP is a method by which the Microsoft Windows NT Server may
|
||
|
|
implement additional security. It is possible to configure the server
|
||
|
|
in such a manner so as to require that the client systems which
|
||
|
|
connect with it are required that following a valid authentication to
|
||
|
|
leave a method by which the number may be returned call.
|
||
|
|
|
||
|
|
It is a requirement of servers so configured that the protocol be
|
||
|
|
exchanged.
|
||
|
|
|
||
|
|
So, this set of patches may be applied to the pppd process to enable
|
||
|
|
the cbcp client *only* portion of the specification. It is primarily
|
||
|
|
meant to permit connection with Windows NT Servers.
|
||
|
|
|
||
|
|
The ietf-working specification may be obtained from ftp.microsoft.com
|
||
|
|
in the developr/rfc directory.
|
||
|
|
|
||
|
|
The ietf task group has decided to recommend that the LCP sequence be
|
||
|
|
extended to permit the callback operation. For this reason, these
|
||
|
|
patches are not 'part' of pppd but are an adjunct to the code.
|
||
|
|
|
||
|
|
To enable CBCP support, all that is required is to change the
|
||
|
|
appropriate Makefile in the pppd subdirectory to add "-DCBCP_SUPPORT"
|
||
|
|
to the CFLAGS definition and add cbcp.o to the list of object files,
|
||
|
|
and then recompile pppd. The patch below does this for Makefile.bsd
|
||
|
|
and Makefile.linux.
