| Last night, a single user (or, at least, a single IP address)
| in China that self-identified as running windows98 and
| Mozilla 4.0 attempted to download sqlite-3.3.12.tar.gz
| 24980 times and  sqlite-source-3_3_12.zip 25044 times
| over about a 5 hour period, sucking up significant
| bandwidth in the process.
| 
| I've seen this type of thing before and have on occasion
| banned specific IP addresses from the website using
| 
|    iptables -A INPUT -s <ipaddress> -j DROP
| 
| But lately, there have been so many problems coming from
| win98 and moz4 that I'm thinking of banning all traffic
| that self-identifies as such in the User-Agent string of
| the HTTP header.

Given 50K attempts in 5 hours, this is either a bug somewhere or it's
automated, likely the latter. In that case, dropping packets based on the
User-Agent isn't going to fix the problem - especially if it's mentioned
here...

It's more work, but something that monitors your log file and selectively
bans IP addresses and/or throttles download speed (keeping the connection
open), might serve you better.
