Bob,

Nice catch.  I'm seeing some of the same IPs (listed below) on my mirror as well.  I'm not sure whether I should block them or not though because I'd prefer not block people actually getting the ISOs but I also don't need bandwidth being consumed for no good reason since my mirror is already maxing out it's caps.

Hi!

I too am being hit, hard..  Although I did not carry DVD iso but the quasi-DOS on the CD iso files are just as bad. Not just bandwidth consumption but several dozens simultaneous connections from a single IP. I think it's due to clients behind these IPs using some kind of download managers.

So much so it is affecting those others who are grabbing *.rpm's download performance.

I am tempted to use mod_bw and limit *.iso bandwidth to a reasonable low max download speed and limitipconn to limit those download manager users to a reasonable simultaneous connection.
