[HECnet] DECnet area router configuration

[Steve Davidson]

A simple batch job will take care of this.   Include in the batch job a "resubmit" so that  you  do not have to  remember to run the procedure in the future.   You might do it  monthly or maybe even weekly.
  
The other direction is a bit more work, but certainly possible.   At this point Johnny has to ensure that no  one creates a namespace collision by using the same node name twice.

Does a COPY KNOWN NODES FROM xxx remove nodes in your local database that aren't listed any more?

It's fairly easy to run a COPY KNOWN NODES command once in a while.   I guess the only piece missing is an automated way for MIM to get updates from everyone else.

The only (and this is a very minor) benefit that I can see in a distributed naming system is that this way each owner of say an area could update the name database for his network and have it automagically propagate, rather than a centralised system we have right now which requires your time to keep up to date.

But it's not really that big a benefit to warrant the effort - just automate the periodic copying of the database from MIM would be my suggestion as well...

Node names are local to each machine, and it is perfectly valid to have
different names for the same node number on different machines (although
perhaps confusing).
How hard would it be to write software as equivalent to DNS?   Not necessarily for general-purpose use, but just for HECnet?

For what? Just copying the nodename database between machines? The
software can already do that, so it would just be a question of
automating it a bit.

If you'd like to get a name lookup done from some central place at each
nodename lookup would be almost impossible. You'd need the source code
for DECnet, and the ability to recompile it for that to be possible. Not
likely, I'm afraid.
