[HECnet] pydecnet zero counters

[Wilm Boerhout]

I live in an environment where explicit access control is the standard, 
i.e. no access until some sort of credentials are provided, so that 
would be ok.

The access control machinery is pretty basic.  HTML can be turned on and off but if on accepts requests from any address that can reach your system.  NML also can be turned on and off.  You can also set it to require authentication (a valid username/password on your system).  But neither of them has any way to say that some senders, or some credentials, permit modify operations while others don't.
