  Re: TWG Netbios encaps of IP...
Is there (or could there be) a spec on how this is done.  We have done
the same thing at Cornell, and Kelly MacDonald has done it for the
KA9Q package.  Presumably all three perform the same function but are
different in every detail and won't interoperate.  I'll volunteer to
have ours change to something else if we can all agree on a standard.
Items that seem to need considering:
         1.  What exactly do you register as a name?  Presumably your
            IP address-- At Cornell, we used the ascii dot-notation
            string, and I believe Kelly used the four-byte binary.
         2.  Lets have a way to find the gateway.  Perhaps findname
            for IPGateway, as is used with NBP on Appletalk.
         3.  Lets have a way to get an IP address dynamically if not
            hard-configured by the workstation user.  I can think of
            two approaches: 1) Using info from the gateway to determine
            net portion of an IP address, subnet mask and subnet portion,
            take a guess for a node portion; addname for the resulting
            IP addr and see if anyone complains.  If someone does
            try another guess.  To get info from the gateway, you would
            have to temporarily register some random name.  2) Have
            the GW assign one from a pool.  The later is the method
            currently used by the KIP code for Appletalk.  (The former
            used to be the method.)
Comments?
