In eMule, eDonkey2000 servers are used to provide an entry point into this network. A connection to a server is necessary to access the network's resources and to make your client known to the network.

Basically a server provides only an index for the files, the connected users share. Searching for downloads or for sources of a download is done over the servers.

A server list update in eMule is only need for a first contact to the network. As soon as eMule is connected to a server it offers intelligent features like Client to Client Source exchange to find sources or automated updates to the known servers.

There are several ways in eMule to update the server list:

Useful Settings in Preferences -> Connections

o Auto-update serverlist at start up
In the directory you unzipped/installed eMule to, you’ll find the file adresses.dat. Open it with an ASCII editor (e.g. notepad) and enter a valid URL to a server.met. Only one URL is supported.
Checking this option, eMule will update its server list from the URL provided in the adresses.dat at start up.

o Update serverlist when connecting to a server
eDonkey servers know of each other to a certain extent. With this options eMule will retrieve the list of known servers from the server it is connected to.

o Update serverlist when a client connects
This feature works upon the connection of another eMule client to your client. Both clients will compare their working servers and update their lists accordingly.

Note:
The later two will keep the server list updated permanently. Regularly updating the server list is not necessary.

Update Server List from URL

Enter a URL to a server.met in the box and press Update. The Log windows will inform you how many new servers were added.

Add Single Server

Enter IP and a server name to add a single server to your list. If a Log messages says Server not added! the server is already in the list.

Add Servers via IRC
The official eMule IRC channels feature a !serverlist command. This command sends you a message with server list URLs. Using eMule's IRC chat, links to a server.met can be added directly to the list by cklicking on them.

Add Server from Web Link
The eDonkey2000 network offers special html links, e.g. ed2k://|server|IP|port|/ to add a server directly to eMule.
