Cool.
New programs:
NML2
New implementation of the Network Management Listener. Supports
SUMMARY, STATUS
and CHARACTERISTICS for NODES, CIRCUITS and AREAS. It does not
support LINKS
and OBJECTS which were in the old version but are system specific
operations which
were only visible from DECnet-VMS systems.
Um. No. OBJECTS are also there in RSX. And I wonder if you mean LINES
when you wrote LINKS. And LINES are also in RSX. Not sure there are
some other systems that also have those types. But they are definitely
not VMS only... And OBJECTS are actually rather relevant everywhere,
it's just not that all systems make them visible. I would say it's
actually nice and useful if they can be shown. LINES are also
relevant, but it does depend a little on the implementation.
No, I?m talking about how entities are handled in the NICE protocol.
I did understand that. :-)
SET/DEFINE/SHOW/LIST commands on NODES, LINES,
LOGGING, CIRCUITS,
MODULES and AREAS use a common protocol format so that VMS, for
instance, can issue a ?SHOW KNOWN NODES? to RSX, Ultrix etc. LINKS and
OBJECTS are considered system dependent entities and and for operations
on those entities NCP will send a request as:
<System-Specific-Function (code 22)>
<Originating system type (VMS == 4)>
<Binary data>
Here?s Ultrix issuing commands to a VMS system:
# ncp tell router sho exec
Executor Volatile Summary as of Sun Jul? 1 08:47:44 EDT 1990
Executor node =? 63.1 (ROUTER)
State? ? ? ? ? ? ? ? ? ? ? ? ? ? ? = On
Identification ? ? ? ? ? ? ? ? ? ? = DECnet for OpenVMS VAX V7.3
# ncp tell router sho known objects
Known Object Volatile Summary as of Sun Jul? 1 08:48:00 EDT 1990
ncp - listener response: System-specific Management function not supported
#
I could have sworn that RSX understood VMS regarding objects, but now
that I tried, it did not.
So I might have been totally confused. RSX also have the command to
examine objects through NCP, but it would appear to be incompatible with
the VMS NICE listener then.
In RSX:
.ncp tell jocke sho kno obj
Known objects summary as of 30-JUN-20 20:58:44
Object Name Copies User Verification
0 Single Default Off
15 TCL... Single Default On
16 LSN$$$ 5 Default Off
17 FAL$$$ 8 Login On
18 HLD... Single Default Off
19 NIC$$$ 5 Default Inspect

27 MAI$$$ 5 Default Off
29 PHO$$$ 5 Default Off
30 DDM$$$ 5 Login On
42 RTH Single Default Off
63 DTR... Single Default Off
.
For LINES, I?m not sure there is much useful
information we can display.
Here?s Ultrix again:
#ncp sho kno lin char

As far as lines goes, yes, there is not too much information available
on them.
From RSX to a VMS node, compared to another RSX node:
.ncp tell frost sho line qna-0 cha
Line characteristics as of 30-JUN-20 20:54:43
Line = QNA-0
Receive buffers = 10, Controller = Normal

Hardware address = AA-00-04-00-FF-63
Buffer size = 1498
.ncp tell jocke sho lin una-0 cha
Line characteristics as of 30-JUN-20 20:55:00
Line = UNA-0
Controller = Normal
Counter timer = Off
Protocol = ETHERNET
Hardware address = AA-00-04-00-15-04
Controller CSR = 174510, Vector = 120
Priority = 5
.
Do people care about this information? Maybe not.
