[HECnet] HECnet bridge and tun/tap problems on Ubuntu 12.04 ...

[Bob Armstrong]

`tcpdump -vvvi tap0`

  Yep, I'll try that tonight.   Gotta go now.

You bridged tap0 to your external interface, right?

  No.   In fact, that's the whole point - to keep HECnet traffic off of my
real Ethernet.

  tap0 is connected to only two things - Johnny's bridge, and QNA-1 (xqb on
simh).   QNA-0 (xq on simh) is connected to my physical Ethernet.   VMS sees
both and, if necessary, routes DECnet across them.
