[comp.unix.ultrix] VMS NCP allows node_number being zero !?

elsen@esat.kuleuven.ac.be (12/19/89)

    There's an apparent problem in NCP (VMS version 5.2) allowing nodes
to be entered with a node_number being equal to zero as in 
NCP>set node 'node address 11.0 ! for example.

  I recently stumbled across this when configuring an Ultrix
system which ,quite correctly, doesn't allow for node entries
such as the ones mentioned above.
(On of our LAN managers had introduced a node at the VMS side with
a DECnet address being equal to 11.0)

Both the VMS and Ultrix DECnet  manuals explicitly state that node_numbers
range between 1 and 4096.
VMS Ncp should report a 'parameter out of range' error when adding node
'11.0' as Ultrix NCP does correctly.

Also does anyone know whether it's possible to do a 'copy known nodes'
in Ultrix ncp ?
I tried my VMS equivalent but to no avail.Yeah I know perhaps I should
RFTM with respect to Ultrix NCP.

	Hmm, if the manuals say 4096 then that sounds like a bug.
	A Phase IV DECnet address is 16 bits, 6 bits for the area
	and 10 bits for the node number within the area.  2 to the
	10th power is only 1024 (ie. not 4096).

	VMS's NCP's "copy known nodes" command is VMS specific (ie. its
	not part of the network management architecture for Phase IV).
	The DECnet-ULTRIX equiv. functionality is provided in the
	unsupported update_nodes utility.  If you have V3.0 or later
	then you have to install the unsupported subset first.  update_nodes
	is documented in the release notes with the other unsupported
	utilities.

	Hope that helps.  Merry Xmas and Happy Networking :-)
