Why
is surfing slow when eMule runs?
Depending on the settings eMule may open quite many connections
and also uses much bandwidth. This can slow down other
internet applications, i.e. surfing the WWW. Especially
wrong / too
high connections settings cause serious performance drops
while surfing.
What
is a Mod?
As anyone can use eMule's source code other people have
developed modified versions of the original one. These
versions are
not supported by the official eMule team.
Are
Mods better or faster?
Mostly no. The official eMule versions profit from mod
development but the modders cannot change the eMule's inner
working much
without rendering it incompatible to the rest of the network.
This fact makes any speed improvements very unlikely.
The mods offer new feature and new bugs which you may like
or not, yet some of them have unfeatures which are extremely
harmful for the whole network. These leecher versions must
not be used and the official eMule tries to cut them down
by security features and by banning them.
Mod versions offered on our forums play fair and stick
to the network's rules.
I
get messages that eMule is banned
The official eMule versions do not create these messages,
they are from mods. If you are using the official version
you can safely ignore or filter them.
Where can I get further
help?
If there are still open issues after reading the FAQ and help you may want
to ask in:
| • |
the
Forum (please
use the search function before starting new threads) |
| • |
IRC - just go to the IRC main window in eMule and press
connect. To enter the english eMule help channel type /join
#emule.
There are also other language chat rooms like #emule-french,
#emule-spanish or #emule-dutch. |
Is eMule
anonymous?
P2P networks all rely on a direct connection of two
users to transfer data. To accomplish this the IP of the target
client has to be known. This IP makes the user identify and
trackable. There are only two ways of guaranteeing anonymity:
routing the traffic over anonymizing proxy servers or bouncing
it across other clients.
Proxy servers have numerous disadvantages. They can be closed
down, the degree of anonymity depends on the trustworthiness
of the admin and the traffic they consume costs a lot of money.
Let's assume an average 100.000 client eMule server. Each of
the connected client causes 10kB/s traffic in each direction.
The server would have to cope with a transfer volume of 2.000MB
(1,9GB)
per second. No one can afford such servers.
Routing all traffic over third clients causes a similar problem as half of the
traffic would be used for anonymizing. This means that each user would have to
upload twice as much as now to keep the network's performance on the current
level.
At the moment a secure and sensible way of anonymity in a P2P network is not
feasible!
My Firewall reports attacks
or why does eMule send mails?
Software firewalls analyse traffic by looking over which ports
the traffic is send. Many ports are commonly used only by
certain applications. Emails for example usually uses port
110 to receive mails and port 25 to send mails. Also trojans
and other pest software uses specific ports.
Now all ports are freely configurable in eMule and some users
are setting them to ports which are normally used by other
applications. This can mean that firewalls report attacks
or think that eMule sends mails only because eMule has a connection
on a certain port.
If you use the official eMule version you can rest assured
that it will not send any unwanted information. Also for the
current version .30b no exploits are known.
My firewall still reports connections
after I closed down eMule
Your eMule gets known in the network as it is a source for
other clients. Also the server propagate your client as source
for the files you share. When you shut down eMule you will
still receive traffic from other clients asking if a connection
is still possible. This effect will subside after a while.
What is the IP Filter?
The IP filter is used to block traffic of certain network
addresses which may be harmful for the network. The most popular
page for filter files is PeerGuardian
or Lussnig's
IP Filter. Add the link to the filter file, e.g. http://www.peerguardian.net/pgipdb/guarding.p2p
to the Update from URL field and press Load.
May I copy the Help / FAQ for
my own site?
You may copy any parts of the Help and FAQ as long as you
keep the author and place a link to http://emule-project.net.
It is nice and shows respect to drop me a note
when doing so.
