Thanks to the replies; it's working now.

At the moment, scp from VMS to (what happens to be) a unix box in the
outside world.  I have a dynamic IP address at home (since a permanent
one is not worth the extra cost) and for the occasional problems when
the connection is working but the DNS is not (either a---very
rare---problem with the dynamic DNS provider or a problem on my side
updating the DNS after the IP has changed) AND when I am not at home 
when this happens AND am aware of the problem AND can log in remotely 
(sounds rare, but has happened), I copy the current IP address to this 
remote system so that I know what it is.

First, I want to get this working soon.  Second, though I hope to
upgrade soon (before Easter?) I'm not sure when.  Third, I'll do a
rolling upgrade and want to be able to fall back in case of problems
without losing any functionality.  Fourth, hopefully one can upgrade
without having to reconfigure!  (I did an upgrade from 7.3-2 to 8.3 (the
same one I am planning to do) including TCPIP upgrade for a fellow
hobbyist (a heavy user of VMS but very much a user as opposed to system
manager) while travelling and was surprised when some TCPIP stuff didn't
"just work" after the upgrade.  IIRC it was only the BIND server (which 
I am not using at home), but this has put some fear into my soul so I 
will read the New Features, Installation and Upgrade, SPD etc manuals 
carefully first.  (I hope he managed to get the BIND problem sorted out 
in the meantime.))
