It's even more fun when you decnet copy between Ultrix and VMS because
VMS thinks "/" means a command line option switch (so you have to quote
Unix pathnames), and csh thinks all sorts of horrible things about "$",
":", "[", "]", and ";" (so you have to '-quote the whole mess).  On top
of that DEC had to invent totally different ways of specifying username
and password for Ultrix, and Ultrix's dcp (decnet cp) is strictly 1 file
per invocation (blecch).

At least Ultrix decnet lets you omit your password on the command line,
and let you supply it UNECHOED in response to a prompt.  I don't know
if it's fixed in VMS 5.0, but VMS 4.x decnet was pretty brain-damaged to
require that you type your password in a nodespec for the whole world to see.

One good feature of Ultrix decnet is tcp/decnet gatewaying.  It lets
a Unix host telnet and ftp to a VMS host that doesn't run tcp/ip services.
It even works for non-VAX Unix machines (e.g., Suns).
