Hi guys,
I've now secured an internet connection for the DEC Legacy event in April and wanted to pick your collective brains about what might be interesting to hecnet hobbyists who won't be able to attend the event if we can get some of the machines that will be in attendance connected up to hecnet on the day.
A couple of my machines will be there - probably the VAX 4000/90 and either the DEC 3000/600 or the ZX6000 itanium workstation - I'm presuming I'll need to supply an updated IP address for Jonny to patch me in given that my bridge will be on a different IP address? Also, would it be possible for those attendees who've not been connected previously to get connected up on the day, given that they won't have to worry about the bridge setup?
Would anyone fancy participating in a coding competition? Anyone have any other suggestions?
Kind regards, Mark.

Yes, the #if stuff I have had to adapt for OS X as well.
I'll try with a cable tonight to see if that works better than wireless...

I have your bridge working on Mac OS X.
I forced
#define __FreeBSD__
to get
ioctl(BIOCIMMEDIATE, BIOCSHDRCMPLT) compiled.
I get the same packets as tcpdump, that is:
- broadcasts from all nodes, if I run on a distinct machine (no simulator)
router-hello, lev-1-routing, lev-2-routing
- broadcasts and unicasts to me, if I run on a machine hosting a simulator
link-service, data-ack, ils-ack, data
I am on a switched network with unmanaged switches, so i'm unable to sniff
all traffic for the moment.

In my local case, the bridge only have one UDP socket, and one local NIC.
I can even reduce it to only run with the NIC, and I still see the problem.

Does you bridge have many connections to it? I recall last time I glanced thru the source code it wasn't using blocking sockets... perhaps its getting 'stuck' on a socket and effectively missing packets...?

Johnny,
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.

Running my bridge program on MAC OS X, I don't get all
packets, but I do get some of them. I can't see a pattern to it.
This is done over wireless ethernet.
The interesting thing is that tcpdump manages to see all of
them. I'm very curious on why tcpdump manages to see packets
that I don't see... Anyone have any ideas?
Feel free to ask questions. I'll happily explain what I have
tested, and done, and whatnot.

Aren't there issues with wireless network connections only supporting a single MAC address thus making bridging not work properly?
Could be. However, in this case, I can definitely see that my bridge are not getting some packets that tcpdump are getting.
That discrepancy shouldn't be there, and is definitely not in the scope of the capabilities of the interface as such.
If I would have a situation where the bridge program and tcpdump would agree, and it still didn't work, then I would start looking at the possibility that the wireless interface didn't support all the stuff I need.
