[HECnet] TAP, SIMH and Solaris

[Brian Hechinger]

I obviously didn't explain myself very well, so here goes.

I've got a machine running simh.   It's only got one ethernet interface on
it.

I need to give it a non-routable IP address so that I can do NAT on the host
that is running simh to give it internet access.   So far I've been unable
to make that happen.

This guy did something similar on linux:

But I can't get that to work for me.

Adding a second physical interface is not an option on this machine.   Getting
a second IP is not an option on this machine.   Just FYI before anyone
suggests that. :-D

I suspect "my" bridge program is not involved here, but I might be wrong...

However, I'm not entirely sure what Brian is trying to do.
simh - fine
multinet - fine
two TAP interfaces - between what?

Multinet talks tcp/ip, so if you get simh to talk through *one* tap
interface, you're done. Not sure what the second tap interface is for...

The bridge only accepts decnet... If you look through the source, you   
can see how it sets up the pcap macro_ and expand it to inclde   
arp,rarp,ip....

I was able to get Johnny's bridge to work between my copy of SIMH and
Steve's side using a TAP interface. So far so good.

Now I'm trying to get multinet to be able to talk to the host via the
TAP interfaces. I've setup a second TAP interface, bridged the two
TAP interfaces and set IPs. I cannot ping, however.

I've found stuff on the internet that leads me to believe that this works
correctly on at least Linux, but even doing things pretty much the same
way I am unable to get this to work on Solaris.

While I continue to search the internet looking for help with this, does
anyone have any experience with this sort of setup?

Thanks!
