    I know you said you have hundreds of thousands, but the sample spamreport.txt only has a little over 20K. Even still, doing just a cursory glance you would be a lot better off not blocking individual IPs.

    use strict;
    use warnings;

    my $spam = $ARGV[0] || 'spamreport.txt';
    open (SPAM, '<', $spam) or die "Unable to open $spam for reading : $!";

    map { $_->[4] }
    sort { $a->[0] <=> $b->[0] || $a->[1] <=> $b->[1]

  • Ah, yes, I should have been more careful with my numbers. And language. Hundreds of thousands of IPs have been banned but not by that script and thus not in that output; they were banned by another script that (guess what) hit ARIN and blocked the entire netblock. I don't want to do this too hastily (in other words, I don't wnat to do this automatically) so the automatic script is doing /32's. Since there is some interest in passing from someone (even if that interest is just stimulating a clarification), h

        Yuck! Don't people have a "preview" button any more? Or read the help text under the textarea, when entering their post?

        Try "<ecode>", it'll preserve your formatting.
