Er wordt gezegd dat je beter niet meer dan 50 bestanden in je queue kunt zetten.
50 bestanden in je queue is sowieso al veel (50 films x 700 MB = 34.18 GB).
Als je eenmaal geblacklisted bent, hoe kun je dan weer van die blacklist afkomen? Je krijgt van de servers dan totaal geen resources meer; die kun je alleen nog vinden d.m.v. de source-swaps die de clients onderling uitvoeren.
Edit: al gevonden op het eMule forum.
"If the credit counter go to 0, you are blacklisted for a while, depending on the server you use, from 10 minutes to 2 hours."
Uitleg:
Explanation on Blacklisting by servers.
You may have already been blacklisted these last few days on Razorback, otherwise you surely remark that more and more people talk about that in our forum.
This system aims to protect servers against aggressive clients.
Historic : previous situation
This system is ready since several months on all lugdunum eDonkey server. Untill now, blacklisted users didn't receive any sources from server during a while (determined by the server's admin), and were not informed of their status. As they can still keep connected, we didn't succeed in modifying the habits of those users, and they didn't realize that no more sources were coming from the server, because eMule partially correct this issue with source exchange. So the number of blacklisted users kept increasing to reach by now 5% of the Razorback's clients.
New measure.
Lugdunum decided to modify the measures against these clients in the version 75 of the eDonkey server. They are now disconnected from the servers, and receive a message pointing the reason.
How does the server determine aggressive clients?
The server attributes for each IP a "credit" of 1200 for a period of time. A counter adds 1 each second.
Each request sended to the server consume a part of credit, see details below.
- 1 credit minimum for each frame, + a variable amount
- 100 credits for each request of connection
- 16 credits for each request of sources for a file the client is already downloading
Consequences.
If the credit counter go to 0, you are blacklisted for a while, depending on the server you use, from 10 minutes to 2 hours.
If during this blacklisting time, your client keeps assaulting the server, the server makes the blacklisting time longer.
Example.
If you download too many files (over 50), you may drive your credit to 0, because 50*17=850 + credits consumed with your connection = 950.
If you share a lot of files, your eMule/eDonkey client sends to server lots of frame to publish.
Cost : 1 credit/frame (~1400 Bytes/frame). If you share and download to many files, you increase the risk to be blacklisted.
In a standard use of eDonkey, you should not be over 40 files downloading and 1000 shared files, so you avoid the risk to be blacklisted. Caution : Share rare files, avoid sharing overdistributed files.
And if you are blacklisted, don't insist, go to another server during a few hours. But if it happens too often, use a less aggressive client.
We are aware of the trouble caused to certain users, but we hope that they will understand a little better the reasons of blacklisting, and change their behaviors so that the eDonkey network can continue to evolve healthily.
Zie het dikgedrukte deel in de quote. Dit schijnt de sleutel te zijn tot het vermijden van een blacklisting. De meeste mensen op GoT zullen toch al niet meer dan 1000 files sharen, en 40 files tegelijk downloaden is wel meer dan genoeg. eMule wordt toch voornamelijk gebruikt voor grote bestanden (>350 MB), films, en ISO's. 1000 films van 700 MB sharen is 700.000 MB, oftewel 684 GB....
Als je je complete MP3 collectie shared, en dan ook nog vele losse kleine bestandjes gaat downloaden, dan hang je zo te zien binnen zeer korte tijd in de prijzen, omdat je met de file- en sourcerequests de server(s) platdrukt.
