Re: [ANNOUNCE] nf-hipac v0.8 released

Hello,

quoted

Apart from that Roberto Nibali did some preliminary testing on nf-hipac.
You can find his posting to linux-kernel here: http://marc.theaimsgroup.com/?l=linux-kernel&m=103358029605079&w=2

Since there are currently no performance tests available for the
new release we want to encourage people interested in firewall
performance evaluation to include nf-hipac in their tests.

 
Yes, I had missed this when I quickly looked at the web page using lynx. Thanks.

One obvious thing that's missing in your performance and Roberto's figures is what *exactly* are the non-matching rules.  Ie. do they only match IP address, a TCP port, or what? (TCP port matching is about a degree of complexity more expensive with iptables, I recall.)

When I did the tests I used a variant of following simple script [1].

There you can see that I only used a src port range. In an original paper I wrote for my company (announced here [2]) I did create rules that only matched IP addresses, the results were bad enough ;).

Meanwhile I should revise the paper as quite a few things have been addressed since then: For example the performance issues with OpenBSD packet filtering have mostly been squashed. I didn't continue on that matter because I fell severely ill last autumn and first had to take care of that.
