[HECnet] Intermittent Connection with PyDECnet?

[Robert Armstrong]

  I always ifconfig the tap devices as up, but maybe you don't have to.
That could have changed. 

  Don't know for sure about tap devices, but if you're not root you won't be
able to access the eth device for your physical Ethernet.

I will have to double-check. I didn't have to manually run ifconfig up (or
the equivalent ip command invocation) on the the other tap that I'm using
for simh, but maybe I do need to do that for pydecnet?

I did not run it as root, since I created the tap interface with the -u flag
to make it usable by my non-root account. But that's another variable I can
try to experiment with.

So, neither of those questions was dumb!
