Trouble setting up networking on the virtual machine? Maybe. But this

Security issues are mostly non-issues. How many script kiddies today
even know what a TOPS-20 host is. There are most certainly
vulnerabilities, but they are very different from the ones presented
by modern machines.
I have an RSX system on the Internet, and it gets constant probing
over telnet and http, but they are all probing in ways that just don't
make sense. So I have never felt more secure.
To Johnnys suggestions I might add that (I don't know exactly what
problems you're having) maybe openvswitch might help out?

The problem is that WiFi is not really like ethernet (I think we covered this a 
month ago, but maybe it was on a different list). Anyway, if you have a simh 
instance using WiFi for the network, it do not work, since putting the 
interface in promiscuous mode, and pretend you have a second machine with a 
different MAC address do not work, since with WiFi, the base station actually 
knows which MAC addresses are connected, and if a packet comes in for a device 
for which the MAC address is not registered, the packet will not be send out 
over WiFi, so you will not get anything, even though you think you have your 
interface in promiscuous mode, and are sending packets out with a different 
source MAC address, which you might think the WiFi switch would learn, as it 
would had it been ethernet.

ah! That do sound familiar. I think it was indeed discussed on this list 
recently. Openvswitch might be useful in the general case, but maybe not for 
wifi.


Actually DECNET over Wifi does work - if you turn off all security, then the 
WAP just acts like an Ethernet hub.

Whether this is feasible (i.e. you live in the middle of nowhere) is another 
question.

That is really interesting to hear. And possibly a bit surprising.
