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

[Bob Armstrong]

Recent simh versions no longer need any external program to work with tap
devices.   

  I saw that - simh v3.9, I think.   I'm still using 3.8-3 (I have some local
patches that I don't want to redo just yet).

  It's a good suggestion, but the fact is that the old simh worked just fine
with Ubuntu 10.04 - it's the upgrade to 12.04 that broke things.
