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

by bob＠jfcl.com

I know that I've seen a patch to simh in the past, to connect to HECnet directly from simh, Yep, I've seen that too, although I don't know the current status. Maybe Mark can put it in the production simh release ? In the meantime, the tap device solves the problem just fine (or at least it used to). Bob

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

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. Bob

Mark, I don't think Bob suggested he used some special program to connect simh to a tap device. What he did was use my bridge to connect his machines to HECnet, which is a step on the other side of the tap device. By the way, Bob, I know that I've seen a patch to simh in the past, to connect to HECnet directly from simh, without the addition of the bridge program. Maybe something to use?

Kuiper/Charon X3.1, Platform: Takara @ 500MHz, MOS Operator Control ???

by mark＠wickensonline.co.uk

So the latest Takara Alpha PICMG Industrial PC picked up from eBay last week has a different firmware image to the last one. Apparently it has something to do with VNswitches, but I'm not sure how it would have fitted in to a bigger picture. It looks like at one point it contained three network cards given the errors. Does anyone have any knowledge of this? It looks like I'm going to have to resort to the technique I performed on the last box when I flashed AlphaBIOS which would then not allow a reflash. I had to set a jumper on the CPU card and create a boot floppy with replacement firmware on. Looks like the 'MOS Operator Control' prompt is a dead sheriff rather than a dead sergeant!

OT - minitrue.su

While funny, this is definitely a little too off topic for my taste... Johnny Can I just close the thread by saying that people should contact me offlist for registrations, KREMVAX, KGBVAX and PRAVDA are gone. Thanks for understanding BQT :)
