I just wanted to alert people that I rewrote parts of the bridge code
recently.
The code was very old, and it started to have problems on some platforms
because of the very ancient way it made use of the pcap library. So I
finally bit the bullet and rewrote it to make use of the pcap library it
is supposed to be used these days. This not only removed some
bugs/issues, but it also allowed me to remove some conditional code for
different OSes.
In addition I also introduced some other changes that others have
contributed, making it hopefully a little nicer to use.
The bridge tarball can be found on:

or

It would be interesting to know more about what bugs and issues you have fixed and what
other changes you have included. Is there a list? Do you publish the code on GitHub?
Regards

No, I do not use github. I hate git (long story, but that is really a
side track here).
The tarball contains the sources, so it's free for anyone to inspect,
play around with, experiment, modify, or use.
The Italian retro-DECnet guys took a copy many moons ago, and did some
changes to it, which they then used.
The major issues that had me work on the code were that on a recent
version of Linux, it no longer worked right. And that was because when I
wrote the bridge, libcap was at version 0.1, and a lot of things I
needed to do was not possible in libcap itself, such as injecting
packets on the network, and control of how buffering was done.
So there was conditional code to set things up for Linux, BSD and
possibly others, using ioctl() as well as write to the underlying file
descriptor, and doing select() on the file, and just hoping it was
allowed. All of these things were added in libcap version 1.0, so it
made sense to remove all my special code, and just use the library
instead, which means the same code should work on more platforms without
any hacks. Linux apparently broke their backward compatibility on pcap
at some point recently, in some undocumented corner that I made use of...
And then people had contributed some cleanup, some more command line
flags and debug abilities that I never had bothered with (I'm lazy, I
change the code when needed).

Is it safe to assume that the new one is backward compatible (i.e. the new version and
the old version can talk to each other)??

I think it makes it a little easier to share source code, see what has changed and to
offer improvements. If people have other suggestions for a suitable repository then that
is fine by me.

I use the bridge that?s part of PyDecnet. It connects a pidp11 (TLEILX) to the rest of the
local DECnet/HECnet and even LAT works well over it.

That one is supposed to be compatible with Johnny's original. If you ever see
problems with that please let me know.
