[HECnet] DECnet area router configuration

[Steve Davidson]

You need to use the "with purge" option for this to happen - at least in
VMS anyway.

Actually, I'm not entirely sure (I don't use VMS much nowadays), but I 
think it might remove all previous definitions before doing the copy.

But that is easy to test. Just add a definition for some odd node that 
don't exist, and then do a copy.

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

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.
