… version 2.0 is out and has a new feature called synchonization mode. It reads pretty good and builds on sharing the data with others. I have denyhosts running but I chose not to aktivate this mode, yet. I am hoping for a release with the denyhosts synchonization server.
Why?
Well, personally I am not really to fond of the idea of gathering loads of IP adresses from other attacked servers and sending my data around, yes, seems helpfull but still doesn’t seem quite right.
Now what makes a lot of sense is for the syncserver to be running for a range of adresses (all YOUR servers, all the servers at a provider, all the servers in your clan, etc.) wherever it is pretty likely that if our server gets hit, the one next to it is most likely to be next.
