hello, i notice now that we have some DDOS attack on our server, and also that few IP (that mostly try to spam our forum) download more than 40 GO of data is their is any tools or script to filter the good traffic from the bad traffic ?? also is their is somewhere a list of IP that should be blacklisted because they mostly do spam ? like spamhaus for the mail server for exemple thanks you by advance for you help !
What configuration you have done on your server? do you have install CSF Firewall that blick the ddos attacks... for spam, i think the solution is use a capcha for each post for block the robots post. let me know more info so i can help you.
it's a IIS7 server (under windows). Yes i use the microsoft windows firewall. but is their anything special to configure on it ? what is a CSF firewall ?? Also how a firewall can help us to forbid an user to download simunatesly 100 pages on our server and do something like a ddos attack on our server ? is their any script for that ? yes we use capcha, but the problem is even with captcha (same captcha that is use on this forum) the spamer still success to post spam, and also they download very much of page (+40 go) before to success to pass some captcha. but for exemple, i know that it's some spamer because when i look the IP under spamhost i see that the ip is blocked for forum spam ! thanks you by advance for you help
