Very possibly. The annoying thing is the fact that tcpdump sees more packets than I (my bridge) do.

Apples MAC OS X pcap library...

Not sure this is related but I tried to run SIMH on OS X over the wireless and DECNET didn't work - it might be more than just a pcap issue, the problem could be OS X's wireless NIC drivers or something. Aren't there issues with wireless network connections only supporting a single MAC address thus making bridging not work properly? --Marc

Speaking of which, it might be a good time to point out that the bridge program works fine on NetBSD, Linux and OpenBSD atleast (I think FreeBSD have also reported success). And I'm now trying this on Snow Leopard. This is the first time I've tried on wireless as well. So in general, there is nothing wrong with the program, nor the filter. I'm just having these problems explicitly on this platform. I can definitely see tcpdump printing out packets while the bridge program sits quite not receiving anything. Johnny Johnny Billquist wrote: Yeah, possible problems with the filter program have been considered. I tried skipping the filter program totally, but that didn't seem to solve my problems. Might be worth examining a bit more anyway. (I have a software check for "valid" packets as well, so skipping the filter don't really hurt, except for performance reasons.) Any suggestion on what libpcap might be good to use? I seem to remember having problems with the network in simh as well, when using it over wireless. I think I should test the wired interface to see if the bridge works fine over that. (I would sure like to check the tcpdump sources if they do something funny...)

I do recall it is quite touchy, and that when I used to build osx libpcap stuff (simh) in the past, I'd just download the latest pcap myself, and manually link that into the exe so it didn't use the system libpcap.....

Mailing list archive / online forum?

Basically, the current use pattern (i.e. emailing to a list and receiving new posts via email) would remain unchanged, but there would be an ability for users to view past posts etc via a web interface? I'd be happy to look at setting this up if there's any interest. Sampsa . Would VAXnotes be an option? It's Freeware now and there are images for VAX and Alpha and even I64. Very little work setting it up. Kari

I'm not sure what you are saying here... Maybe I'm dense, or something. I'm not aware that this list (or some people) on it have surmised anything. Can't speak for the NetBSD-list, as there are way too many people there, with different knowledge and experience... And in my mind (atleast) it has been known since the dawn of time that the DEC MMJ connectors are RS-423. See for instance http://en.wikipedia.org/wiki/Modified_Modular_Jack The MMJ are RS-232 compatible (as is RS-423), the adapters just do the wiring properly, and that's it. Friday at last. HECnet seems to be running pretty stable at the moment. A few machines come and go, but we seem to be pretty stable on which areas are online.
