Ed2k links handling

English | Deutsch | Nederlands | Korean

The way to make aMule handle your ed2k links on your favorite web browser will depend on which web browser you use and which operating system you have installed. So, here's a list of mini-HowTos for each of the most popular web browsers and operating systems.

Have in mind that everywhere on this document, /path/to/ed2k should be replaced with /usr/local/bin/ed2k, /usr/bin/ed2k, c:\Program Files\aMule\ed2k.exe or whatever, depending on your own system's configuration.

Local handling of ed2k links

GNU/Linux

As a general idea, in most Linux systems, self-compiled aMules will install the ed2k utility in /usr/local/bin/ed2k, while package-installed aMules will install it in /usr/bin/ed2k. As an exception, it is known that SuSE packages install it in /usr/local/bin/ed2k.

If you have installed Debian or Ubuntu you must install "amule-utils", and "amule-ed2k" to get this way working.

Firefox 2 and 3 (or later)

Handling ED2k links in Firefox can be configured in two ways: either for an individual user, or for all users of the computer.

Configuration for a single user

• Insert about:config in the address bar

• Right click on the list, select New, then Boolean; insert network.protocol-handler.external.ed2k as Preference Name and true as Value

• Now another right click, select New and String; insert network.protocol-handler.app.ed2k as Preference Name and /path/to/ed2k (path to where the file is installed on your system) as Value.

For Firefox 3 and higher only, you should also:

• Right click on the list, select New, then Boolean; insert network.protocol-handler.expose.ed2k as Preference Name and false as Value

After that, click over an ed2k link, and Firefox should ask which app you want to use to open the link. Choose /usr/local/bin/ed2k and it should work.

System-wide configuration

• Having root privileges, open the file /usr/share/firefox/greprefs/all.js (or /usr/local/share/firefox/greprefs/all.js) in a text editor

• Add the following lines at the end of the file:

// ED2K link handling
pref("network.protocol-handler.external.ed2k", true);
pref("network.protocol-handler.app.ed2k", "/path/to/ed2k");

Substitute the "/path/to/ed2k" string with the program's real path.

For Firefox 3 and higher only:

• Add yet another line to the all.jsfile:

pref("network.protocol-handler.expose.ed2k", false);

After saving changes, restart the browser. After clicking over an ed2k link, Firefox should ask which app you want to use to open the link. Choose /usr/local/bin/ed2k and it should work.

Opera

In Opera go to Tools -> Preferences -> Programms -> Add...

In the "Protocol" field enter ed2k

In the "Open with another application" field enter /path/to/ed2k

Konqueror

To have ed2k links work from Konqueror you have to add a protocol-file to the directory with the other protocol-files. You can find this directory by searching for file names ending with .protocol. To search run `find /usr -name "*.protocol"` or `find /opt -name "*.protocol"`. If you're not sure about the directory where KDE is installed you can even put / as search path.

If the search was successful, create a file named like ed2k.protocol in the mentioned directory:

[Protocol]
exec=/path/to/ed2k "%u"
protocol=ed2k
input=none
output=none
helper=true
listing=false
reading=false
writing=false
makedir=false
deleting=false

Now just restart Konqueror.

NOTE: You might get a security warning. don't worry. it is just warning you that the link is being sent to an external application.

NOTE2: If after clicking OK on the security warning the link is still not being sent to aMule, just right-click on the ed2k link and tell Konqueror to open it in a new window/tab.

Galeon

Execute the following three commands to create the appropriate gconf keys:

• gconftool-2 -t string -s /desktop/gnome/url-handlers/ed2k/command "/usr/bin/ed2k \"%s\""
• gconftool-2 -t bool -s /desktop/gnome/url-handlers/ed2k/enabled true
• gconftool-2 -t bool -s /desktop/gnome/url-handlers/ed2k/needs_terminal false

Replace "/usr/bin/ed2k" above with the path and name of the ed2k executable on your system.

Uninstalling this protocol handler is similarly simple:

• gconftool-2 -u /desktop/gnome/url-handlers/ed2k --recursive-unset

Links

(Probably this will work for the usual links and/or elinks, too)

add to url.c behind the lines about telnet and tn3270:

 --snip
 {"ed2k", 0, NULL, ed2k_func, 0, 0, 0},
 --snap

add to links.h behind the definitions of /* mailto.c */:

 --snip
 void ed2k_func(struct session *, unsigned char *);
 --snap

add to mailto.c at the end:

 --snip
 void ed2k_func(struct session *ses, unsigned char *url)
 {
 tn_func(ses, url, options_get("network_program_ed2k"), TEXT(T_ED2K), TEXT(T_BAD_ED2K_URL));
 }
 --snap

add to options_register.c behind telnet and tn3270:

 --snip
 register_option_char("network_program_ed2k", TEXT(T_ED2K_PROG),NULL,2);
 --snap

add to intl/*.lng behind

 "T_TN3270_PROG": T_ED2K_PROG, "ed2k program", (or whatever that is in your language), behind
 "T_TN3270": T_ED2K, "ed2k", and behind 
 "T_BAD_TN3270_URL": T_BAD_ED2K_URL (I guess you've got the picture)

If you want to automatize this stuff, execute the following commands:

 cd intl
 for l in *.lng; do
   cp $l $l.bak
   cat $l.bak | sed -e "/T_TN3270_PROG*/aT_ED2K_PROG\, \"ed2k program\"\," \
    -e "/T_TN3270,\ */aT_ED2K\, \"ed2k\"\," \
    -e "/T_BAD_TN3270_URL*/aT_BAD_ED2K_URL\, \"Bad ed2k url\"\," > $l
 done
 

Anyway, run afterwards before recompiling links-hacked:

 ./synclang
 cd ..

Now you can compile with

 ./configure (add your favourite options here) &&
 make &&
 make install

Because links somewhat malforms the urls, we need a small bash script handler:

 cat > /usr/bin/ed2k4links.sh << "EOF"
 #!/bin/bash
 ed2k $(echo "ed2k://$1" | sed s/_/\|/g)
 EOF
 chmod a+x /usr/bin/ed2k4links.sh

Do not forget to setup links (Options->Network Options->Mail and Telnet Programs) to call our ed2k4links.sh for ed2k links:

 ed2k4links.sh %

Attention: The Percent Mark is important! Now links should work with ed2k links.

Windows

To make Windows aware of the ed2k link protocol we need to add some keys to the registry. Create a file called ed2k.reg and add this code:

REGEDIT4

[HKEY_CLASSES_ROOT\ed2k]
@="URL: ed2k Protocol"
"URL Protocol"=""

[HKEY_CLASSES_ROOT\ed2k\DefaultIcon]
@="C:\\Program Files\\aMule\\amulegui.exe"

[HKEY_CLASSES_ROOT\ed2k\shell]
@="open"

[HKEY_CLASSES_ROOT\ed2k\shell\open]

[HKEY_CLASSES_ROOT\ed2k\shell\open\command]
@="\"C:\\Program Files\\aMule\\ed2k \"%1\""

Save the file and run it (double click) to add these keys to the registry.

Internet Explorer

Internet Explorer will recognize ed2k links with just the changes in the registry.

Mac OS X

Adapted from Ken's post in the forum.

1. Run aMule at least once
2. Run Safari (even if you normally use Firefox or another browser)
3. Browse to a page with an ed2k link that you want to download
4. Drag the link to the location field at the top of the window
5. The OS will present a dialog asking if you want to allow a program to run to handle the link. Allow it.

Now, the program that helps aMule handle ed2k links is known to the system.

Safari

If you use Safari, you will have to drag the link to the location field every time. For unclear reasons, Safari will not process ed2k (or other non-Apple protocol) links if you click on them.

Firefox

If you use Firefox, clicking on an ed2k link will work. The first time, for security purposes, Firefox will present a dialog asking if you want to allow the helper program to run. (Yes, even though the OS already asked you the same question.) After that, it will work just as you would expect.

Remote handling of ed2k links

You can also handle links remotely, which means that you click over an ed2k link in a browser somewhere in the world and it gets into your home's aMule queue. It works by using aMuleCMD instead of using the ed2k command.

Linux

Instead of using the ed2k command, use the following as the command to use:

/path/to/amulecmd -h $server -P $pw -c "Add %u"

Obviously, you'll have to replace $server and $pw with your server's IP (or DNS) and your External Connections password.

NOTE: In Firefox, it is not possible to start a command with parameters. An easy solution is a shell script with the command described above. You only have to replace %u with $1. This shell script must be executable (chmod +x ed2k.sh) and defined as external ed2k app in Firefox.

Windows

Make sure aMule is installed with the aMuleCMD option checked.

We need a batch script to handle the ed2k links from the browser, and we need to add some keys to the registry to make the browser recognize the ed2k links.

Create a file named ed2k_remote.bat containing the following code:

@echo off
set link=%1
for /f "useback tokens=*" %%a in ('%link%') do set link=%%~a
"c:\Program Files\aMule\amulecmd.exe" /h server /P pass /c "add %link%"

Don't forget to replace server and pass with your data and save the file in your aMule directory C:\Program Files\aMule.

Create a file named ed2k_remote.reg containing the following code:

REGEDIT4

[HKEY_CLASSES_ROOT\ed2k]
@="URL: ed2k Protocol"
"URL Protocol"=""

[HKEY_CLASSES_ROOT\ed2k\DefaultIcon]
@="C:\\Program Files\\aMule\\amulegui.exe"

[HKEY_CLASSES_ROOT\ed2k\shell]
@="open"

[HKEY_CLASSES_ROOT\ed2k\shell\open]

[HKEY_CLASSES_ROOT\ed2k\shell\open\command]
@="\"C:\\Program Files\\aMule\\ed2k_remote.bat\" \"%1\""

Save the file and run it (double click) to add these keys to the registry.

Internet Explorer

You should be OK with just the changes to the registry and the batch script in your aMule directory.

Firefox

The first time you click an ed2k link in Firefox you will get the following dialog:

Tick the Remember box and click OK.

Opera

Open the preferences window and click the Programs tab

Click the Add... button

Make Opera aware of the ed2k link protocol with these settings:
