Steps to report a server

[Mr.Gucci]

my server SASN RPG have been under attacks many times and i have the evidence of those attacks by the messages that

my Hosting company sends me, but i dont whos attacking...

Actually there's nothing we can do in here about that but you can ask for protection if you mean DDoS attack from your host provider.

Sounds like a pretty bad host to me if they just notify you about you're being DDoSed when they could at least offer you some kind of DDoS protection even tho you may need to pay more for that.
