Re: hurting overall performance sounds like something ...
One thing you fail to notice, that the clients can masquerade as another client. Also, some clients won't also have the option to not even disclose what the client is. |

| It doesn't matter. I've tested this and here is what I've found. I started a download and allowed 100 connections. 98 were Azureus the other 2 UTorrent (which is the only other client I allow to connect) Azureus will detect a client that doesn't disclose what it is as "unknown" and it will also be banned. In short, anything that isn't Azureus or UTorrent are on my banned list. Stuffer allows me to use a string or regex to ban every other client even if they try to disguise themselves as some form of the 2 clients I allow. End of problem

Ada, OK | That works as long as you can trust the other peer's client to report its name accurately 
Hint: You can't. |

| *Sigh* It doesn't matter what the other client reports or doesn't report. They can be blocked. I let one run all last nite just to test. 354 bans.

The name of the client is just something it is programmed to tell you. If I'm making my own BT client, can't I very well call it whatever I want? Don't you think I could make a client and have it tell you it is Azureus 2.5.0.4 when it really is something else of my own production? Or maybe I really DO have an Azureus client, but I have modified its code to employ a more selfish unchoking algorithm (there are already MANY such alterations of Azureus available online, it is a popular program for modding).
There are even clients that have functionality to allow the user to set the name it will report to other peers. For an example, look at this screen shot from G3 torrent (I'm not saying it is a bad client at all, but just to show that clients can do things like spoof their names easily): »g3torrent.sourceforge.net/spoofer.png
So, anyway, the point is that you can't assume a client is really the official Azureus or uTorrent just because it says it is. The more people use such name-based blocking (like you do with stuffer), the more that other clients will start calling themselves Azureus and uTorrent or something that's considered "good".
I hope that it makes sense now. |
