Urgent! Need help with abuse-detection and prevention
I've lately experienced excessive Apache-usage (to be clear: several
hundered open connections in a very short time) to one of my servers. And I
believe that FTP etc. are also subject to similar attacks. For Apache it
resulted in problems that all processes were in state "reading" without
actually doing anything ... a simple but efficient DOS for the
httpd-process, that also caused it to die immediately.
Can you give me any suggestions how to set up basic iptables-filtering-rules
easily and how to prevent such abusive connections?
Your urgent help would be really much appreciated. Kind regards,
