DECnet/E definitely implements NICE, has from the beginning (i.e., from
when DECnet/E 2.0 which is the Phase III release was first shipped).
However, it need not be enabled as a known object. And if enabled, it
may or may not accept connections without access control variables
(PPN/password). If not, you'll get a reject indicating either no such
object or bad access control. However, if the connection is accepted you
should find a full implementation.
Of course mapping information exists only in routers; if the node
you're talking to is an endnode it will only tell you who the adjacent
designated router is (or the adjacent nodes, on point to point circuits).
In this case not enabled then, I think. Thanks for clarifying that it
exists. I only did a reflection based on trying to look at an RSTS/E node
just the other day that did not give me anything.
.ncp tell marduk sho exec
NCP -- Show failed, Listener connect failed, network resources
If it's not enabled I'd expect an error. Network resources is a bit
odd. Possibly there is a default account defined but that account doesn't
exist, or is configured as "no network connections allowed".
