Don,
My friend the crypto expert told me that crc is easy to attack,
and suggested ABCD(EF) because it has the right properties to
resist attack. It would take more work for me to demonstrate that
crc is bad, and to better understand ABCD and possibly adjust it,
but just on the basis of
I analyzed the part res ^= (res 24); res ^= (res 8); a little more in
the rt_hash. What it really does is that it applies the hi bits in the 32bit
integer on the low ones. This means that we wont just throw them away when
we apply the %-operation on it. This is what keeps the good distribution.

All graphs here look about equally good. I dont know if there is a bug
somewhere in cttest that might do this.
I don't
Now there is http://bei.bof.de/cttest-0.5.tar.gz and an example
presentation at http://bei.bof.de/ex4/
As nobody requested the tarball yet, I've remade it with the latest
64 bit ABCDEF code from Don. I also remade the ex4/ pictures,

Actually you could consider proto almost a constant.. I don't think
you really gain anything by obfuscating this..

The recent message about something in conntrack that does not have to
be atomic reminds me of a question.
I'm about to implement something that cannot afford to lose track of
connections. Is conntrack now suitable for such a thing? If

Hi,
This may not be very relevant to the type of discussions done via this
mailing list but doesn't heart to ask anyway. So here it goes:
I have a laptop running linux and configure as the gateway between a local
