That looks to be working OK. It's very bursty to some locations, e.g.
BOPOHA, but connectivity is connectivity. Thanks!  Out of interest, what
is reason for using TCP as the underlying transport protocol instead of
the default?  I've configured the link with a reasonably high cost in
case I make another connection somewhere more local.
This is my first experience with DECnet over more than a few local
nodes, is there an easy way to get a full node list onto my systems?
This all takes me back a while. Last commercial VMS/DECnet systems I
used were back in 1994.  I actually stumbled across hecnet whilst trying
to find out if anyone still used uucp for anything. I was the last
sysadmin of the UKNET uucp setup, then managed by PSINet before we
finally dismantled all that infrastructure in 1999.
