It kind of looks like this might require patching and not just updating of a program version, but... The version of prozilla currently in portage tries unsuccessfully to find download mirrors from ftpsearch.lycos.com, which no longer searches ftp sites. The website has a new version of prozilla that searches somewhere else, but it might be an only graphical version of the program. I'm not positive what's going on over there. I list this under portage because prozilla is probably used by many people mostly for downloading the packages they're installing. It's important enough to be included in the example make.conf file, for one thing, and its proper usage would also help spread bandwidth around instead of hitting a few server.
I won't fix this. As a server admin I find prozilla and any other "download manager" that does many simultaneous downloads as unsocial and poorly behaived. Servers are often configured to provide the best overall experience to the most number of users. When a user is so selfish to think that for some reason they deserve more bandwidth and make many connections which creates a heavier load on the server I stop wanting them as a user.
Well first of all, it's the responsibility of the server to enforce good behavior upon its users. To try to enforce good behavior by the crippling of the clients is somewhat misguided. More importantly, though, fixing this bug would have the main effect of stopping a group of people from making multiple connections to one server by giving them the ability to download from multiple sources instead. Because of this, a fix would be very good for both users and servers.
solution: don't use ftpsearch. Prozilla will still download just fine in multiple threads from the urls you give it.
By "the urls you give it", you mean the single url gentoo provides the downloader? This is not a solution to the bug at all, you would be better off saying "solution: use wget instead of prozilla". Come on, I know I shouldn't have to spell it out to you... unless Gentoo (portage or whatever) gives prozilla multiple urls from which to download, and as far as I know it does not, prozilla will basically be hogging bandwidths of the servers by subverting per-connection caps. The other side of the coin is that if prozilla was given multiple sources and/or the ability to find the sources on its own was fixed, then there would be quite a bit of benefit that would come from spreading of bandwidth usage. Basically you need to either come up with a way to provide prozilla with multiple URLs, fix its ability to search, or configure it by default to use singlethreaded downloading.
