My server keeps going offline after hours of it been stable. I believe it is DoS attacks but I'm really unsure how to block them, would I need to get a firewall? if I do would this help the problem? I really need help with this guys.
how do you know its a dDOS attack? Is it completely offline? is it responding to SSH or just not web/http? Can you ping the server? Need more info... I can assist you with blocking a possible dDOS attack, however we need to analyze what type of attack it is in order to block it. Regards, SSANZ
Having a firewall on your server is the first thing you should do but you would need to give more info on the attack, can you get into the server or ssh to it at all, find out if it is one ip that is doing the attack and then block the ip from your server.
I contacted my host and they said the server has been online and in working order for 44 days, with no problems at all. They upped the maxclients to 1K and blocked a couple of i.p#s from the server. Everything seems to be fine now.
