ppp-2.3.0-static.diff

	Patch to ppp-2.3.0 to support using static IP addresses with 
        Mgetty and AutoPPP.  Does not affect normal dynamic assignments.
        This patch is for 2.3.0 only and not very well tested, comments 
        welcome. Apply with "patch -p1" in the top directory of the 
        ppp-2.3.0 sources. After getting ppp-2.3.0 to compile cleanly on
        your system, patch and re-compile.  (No need to re-compile kernel)
        While the patches should work with any authentication method, we 
        did not have success getting 2.3.0 to work with USE_PAM=1 option. 
        (Out of the box). We use shadow passwords and "make HAS_SHADOW=1". 
        Bottom line...you should get ppp-2.3.0 working BEFORE you apply 
        the patches.        

        After patching and re-compiling, update the pap-secrets file to 
        contain the entries of those users you want to have static 
        IP addresses. Typical entry might look like:

        #client     server     secret     IP addresses
         jdoe         *        realpswd   207.69.189.15 
           *          *         ""            *
         
        Also, inform your static IP users to include their IP when
        connecting. ex: pppd 207.69.189.15:
        Or for Windows folks "check"  Specify an IP address.

  Note: The second line is what most folks will use to authenticate
        users who will be dynamically assigned their addresses by 
        /dev/ttyXX. This along with the login option allows users to 
        be PAP authenticated against the /etc/passwd or /etc/shadow.
        If you enter each and every user into your pap-secrets file
        and do not have the last line,(wildcards line) you MUST place
        a "*" at the end of each users line.  Without it authentication
        will fail.  For example:

        #client     server     secret     IP addresses
         jdoe         *        passwd     207.69.189.15 *

        This "*" at the end allows the patches to work properly without
        changing the normal process.  The IP address is normally assigned
        via the /etc/ppp/options.ttyXX file. The patches do not interfere
        with this process at all.  The only thing different is when the
        user tells pppd he has his own address, pppd will allow him to use
        it, if he and his address are authenticated via the pap-secrets file.
        The only thing to remember, is tell your static IP users to set the 
        "correct" IP or they will be assigned the normal dynamic address. 
        (And of course that's not what we want) :>)  If you have any 
        questions....

While I tested this as many ways as our systems would allow, no warranty 
is implied.  They work well for us.
