First sorry me if this messages is out of topic for some email-lists, but if some one know a solution, please help me.
Hi was victim of a DOS attack, my server was out for about 5 hours, services like web and email where down. I am using round robind dns for a load balancing, but this only help for my web services, any idea on how can i make a redundant service for web and email services? something like mysql does with his replication function? I don't want to use hardware only software regards
