Multi threading/ Multi worker setup

[mosajjal]

Hi,

I'm using passivedns on a big chunk of traffic but it only uses one core and one process. Is there any way we can add threading or worker functionality to passivedns? I believe the choke point would be the log file being written on from all the different processes. Any ideas?

Cheers,

Hi,
I used to use pf_ring and zbalance to do this. But two year ago I was looking into how to write some code to do the same with af_packet, but ended up writing passivedns in golang instead.... using af_packet and fanout....
I use this in production here... My hope is to clean up the code and push to github one day!
The golang version is more aimed at my use (core pdns functionality), but with user inputs, it might evolve to something others want to use to.

I did end up writing a piece of code to do this using golang as well (mostly borrowed from gopassivedns), gitlab.com/mosajjal/dnsmonster. any PR and/or contrib is welcome :) we can join forces to build something scalable if the end goals match

Nice! Read your blog! When I get time, Ill look over your golang code. My golang version of passivedns outputs json to a logfile. But yeah, other output plugins should be trivial to add I guess. Ill ping you when I get up to speed.
