This is the line in regex.pm that should block it.

Code: Select all

       if (($config{LF_FTPD}) and ($globlogs{FTPD_LOG}{$lgfile}) and ($line =~ /^(\S+|\S+\s+\d+\s+\S+) \S+ proftpd\[\d+\]:? \S+ \([^\[]+\[(\S+)\]\)( -)?:? - USER (\S*) \(Login failed\): Incorrect password\./)) {
        $ip = $2; $acc = $4; $ip =~ s/^::ffff://; $acc =~ s/:$//g;
                if (checkip(\$ip)) {return ("Failed FTP login from","$ip|$acc","ftpd")} else {return}
        }

The problem is that regex fail because of the "." at the end. /var/log/secure doesn't have dot at the end, but regex has.

They've updated the format.
Anyone can share a working regex?
