I'm using a dedicated bridged-tap interface in FreeBSD, and DECnet is certainly enabled in TOPS-20, but there is absolutely no DECnet traffic on the wire. None can be seen with tcpdump. I find this very odd. IP connectivity works fine, and I can see LAT traffic, but no DECnet. Any suggestions? Well, I can only say that we have one KLH10 system (PAMINA::) running here. Works fine. But it's running on a Linux box, and also have a dedicated physical interface. No ideas why it don't work for you. Johnny Personally I've always recommended Linux/x86 and a dedicated interface for KLH10. For SIMH I just run on whatever is handy, but I've never gotten networking going with SIMH (I've used real PDP-11 hardware or E11 instead). As I recall I've had DECnet running with TOPS-10 7.04 on KLH10, and TCP/IP for TOPS-20. At the time I was messing with it I wasn't really using DECnet, just LAT and TCP/IP. Plus I'm not sure, but I don't believe DECnet was an option for TOPS-20 at that time. LAT is real nice since if you have a DECserver and terminals, you can easily use a real terminal with KLH10.
