All of the hardware support will have to be ripped out of course, but there are nice tight implementations of generic library functions in there. I took a look at that. It seems to be largely assembly code, which makes it not very helpful. I've lifted more than a few routines from it, and they've all been C. Guess I just got lucky. Sorry for the false start. No problem. Meanwhile, I'm digging through the rt11 sig tapes from trailing-edge, which seem to have various bits of decus c in them. It's hard to sort out what's what but I ran across a directory full of libc type things in c. So that looks promising. I also found RSTS libc pieces, which is nice for another day... paul

DECnet on 4.3BSD/TOPS-20 and other questions

I think it'd be cheaper for me to find some DSSI drives. (Or add a DSSI <-----> SCSI adapter in to the mix ) Well, trouble is, they're drying up fast. Think I could make a VAX work with iSCSI? ;) That's an idea! Would be easier on a weekend due to my eyesight making me unable to drive, so i'd need someone to drive me there. Although I have a few friends a little ways from Pittsburgh who might be able to help in some way. Me getting there directly is a bit challenging, both due to my eyesight and possibly being the youngest here ;). Understood. I generally don't differentiate much between weekdays and weekends, so either is fine for me. (You have no idea how hard it is to get this working in a VM ). Oh yes I do. ;) I virtualized a gaggle of SCO OpenServer machines for a customer about two years ago, using VMware. Oh man that was a mess...VMware was the only virtualization platform that would work, and even that took some doing. They're all still running, though, but now on VERY different hardware. :-) At least it's not Hyper-V I couldn't get anything to run in Hyper-V save for windows. And not even NT 4! Eeeeeek! -Dave -- Dave McGuire, AK4HZ New Kensington, PA

Ah, I don't know anything about Multinet. Is there a reason why you can't use the bridge in that case? The bridge program probably would have worked better, but since I'm shutting down the server hosting these virtual machines (along with a couple Solaris VMs, a Linux VM, and a Windows VM), it's easier just to keep the stuff offline except for the rare times when I might need to boot up a VMS or PDP-11 system. (Given the amount of times I've accessed the systems in the past year, I suspect that it's more about archiving them for reference.) --Marc

I might be being stupid here, but I don't see what problem that would cause, the bridge runs over UDP. Or are you talking about some other way of tunnelling DECnet over IP? I'm not using the bridge program. I'm using MultiNet's DECnet-over-IP circuit. It sends packets to the remote system over UDP on port 700. The problem is that its source port is also 700. My firewall randomizes the source port for security reasons and is not configurable in that regard. When the destination system receives packets from my network, it drops them because they don't have the right source port. --Marc Ah, I don't know anything about Multinet.
