One more diff: http://pdp-11.nsk.ru/~form/files/bridge/bridge-tap.patch
It contains my previous path for OpenBSD and adds support for OpenBSD/Linux `tun' interface, so you
can use it for SimH:
bridge.conf:

[bridge]
tunnel @tun0

Grab it, compile and test. There are also some improvements and bugfixes there. Not that maybe you had seen them in real life, but never the less...
The file I wget'd is date 2010 and compiled to the exact size of the last version I was using...
http://www.update.uu.se/~bqt/bridge.tar
Is that right?
That sounds wrong. I just checked again, and the tar-file is dated today, as is the bridge.c file inside.
And your url is correct.
Check the file size. bridge.c should be 15897 bytes.

It can be interesting for me to create a diff on it, if I don't know
which version you branched from. Or, if you have the unchanged sources
around somewhere, do a "diff -c <orginial> <your version>", and send me
the result of that instead.

Send a diff to me instead. I probably have some stuff that I've worked
on in the code which haven't been distributed. And it's also in general
a bad idea to have the code distributed from different places with
different versions.
I'll put a new version up as soon as I've merged stuff, which will
probably be tomorrow, if you can get me the diff today. And after that,
it would be nice to have people test it at their systems.

*Subject: *[HECnet] Windows Version of Bridge
I just wanted to let you know that I have ported the bridge code to
Windows. It seems to work well for me. If anyone is interested in a
copy, let me know.
I think that it needs just a little bit more work to do the following:
1. Tidy up some bits that I almost certainly left behind while
trying to
get it to work.
2. Turn it into a Windows Service so that it starts automatically when
Windows starts.
Another feature which would be nice to add generally is something which
periodically re-resolves the DNS names in the config file to IP
addresses, so that people who use something like DynDNS because they
don t have a fixed IP address, can use it more easily and not fall off
the network for too long when their IP address changes. Presumably
calling the SIGHUP handler (read_conf) every so often would do the
trick.
It would also be nice to make the code a bit more portable so that it
will compile and run on more platforms without modification, a bit like
SIMH.

Rob
