Hi there, I'm trying to get my server hardened by blocking requests to 404 requests, since I'm getting flooded by them on a DDOS attack.

I have the following log format example for my apache log in virtualmin

Code: Select all

37.59.96.198 - - [07/Aug/2014:06:25:45 +0100] "POST /xmlrpc.php HTTP/1.0" 404 104 "-" "Mozilla/4.0 (compatible: MSIE 7.0; Windows NT 6.0

I've tested in rubular and it works fine.

I have the following code in regex.custom.pm

Code: Select all

        if (($globlogs{CUSTOM1_LOG}{$lgfile}) and ($line =~ /^(\S+) - - \[.+\] (".+") 404/)) {
                return ("404 error for url $2",$1,"404error","5","80,443","1");
        }

my custom1_log file is set correctly...

Have restarted csf/lfd, and I can hit the site with ab to test, and I get nothing

Any idea where and what I can do to work out the problem?

Thanks

May be it could that you have:
if (($globlogs{CUSTOM1_LOG}{$lgfile}) and ($line =~...

instead of what is set in the example inside regex.custom.pm:
if (($lgfile eq $config{CUSTOM1_LOG}) and ($line =~...

Could it be why it is not working?
