    True.

    Well, if one can define access lists using DECnet addresses as filter
terms, I'd be ok with that, for nonprivileged access.

    I've just verified that a MOP console request works from Linux using
locally-stored authentication on the IOS side to establish a
nonprivileged IOS CLI session on a 7206VXR running IOS 12.3(22), like so:

$ moprc -v <MAC address>

    ...and like this from NCP under VMS:

NCP> connect node gw physical address <MAC address> via <circuit-name>

    Note that the MAC address must have its octets delimited by colons
under Linux, and hyphens under VMS.

This is a service (protocol?) called Console Carrier Request. If you have Phase V, I think you use SET HOST/MOP under VMS.

Under RSX, there is a special program called CCR that you use.

And correct, this is not a routed protocol, so you need to be on the local network, and you cannot go through NCP on another machine using TELL. :-)

I'm going to play with this. I think this is the solution to keeping cisco queries in-band.

I'll report back on how I plan on using this.
