[Simh] running on Debian

[Peter Svensson]

I have always found the tap+bridge style easier than pcap. It works just as you would expect a separate computer to work.  With pcap I was never sure what happened when talking to the local computer.

Bridged virtual interfaces is what you use for other virtual machines,  why not simh?
