No, I?m talking about how entities are handled in the NICE protocol. 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
#
For LINES, I?m not sure there is much useful information we can display. Here?s Ultrix
again:
#ncp sho kno lin char
Known Line Volatile Characteristics as of Sun Jul 1 09:00:49 EDT 1990
Line = QNA-0
Controller = Normal
Protocol = Ethernet
Hardware address = aa-00-04-00-df-fc

Recently I have found, and fixed, a number of
bugs in the DECnet for Linux kernel module. Some of
these bugs may be relevant for members of this mailing list who are using DECnet for
Linux,
especially on a Raspberry Pi.
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.
