Hi, Someone attacked one of the server I am managing recently. That server is stand alone apache server with very high traffic. It does not have cpanel installed. So, I installed dos_evasive on this fedora core 4 server. The thing is, to compile dos_evasive into apache, I need to have httpd-devel package which I did not install. I install dos_evasive a rpm package. It installed fine and I tested with included test.pl file. Problem is, I keep on getting HTTP/1.1 200 OK HTTP/1.1 200 OK .. .. .. HTTP/1.1 200 OK No matter how many times I try. If not mistaken, I should be getting error accessing after certain times of persistent connection. I then remembered I had this mod_evasive installed on one of my cpanel server. Tested the test.pl script and found same results. So, now I need to fix the mod_evasive on this cpanel server as well. Anyone have any idea how I should go about fixing this? Is this httpd-devel really needed?
