Not to be confused with lMule
iMule (invisible Mule) is a free open source anonymous P2P file sharing software which connects through the anonymous I2P network and the Kad network.
iMule is based on the aMule source code and uses the Kademlia algorithm and the I2P network. The eDonkey network used in eMule and aMule, which connects through servers, has been dropped. iMule downloads and shares files without revealing the IP addresses and identity of its users.
Like aMule, iMule aims to be portable over multiple platforms with the use of the wxWidgets library. Current supported systems include Linux, Mac OS X, various BSD-derived operating systems, Windows and Solaris.
iMule can be downloaded from the official website, mirror sites, and through ed2k links. The official homepage has been down for a long time, but came online in January 2012 with a new version, though users may still use one of the mirror sites to fetch iMule 184.108.40.206 or 2.0.1. This version will support newer wxWidget libraries as well.
Stand alone mode
Since v1.2.3 (2003), a router program was included inside the source code so no other software is necessary to connect to the I2P network. However, there are still a couple of packages (especially for Linux) which don't have an internal I2P and thus do require the external I2P router software. If the user wants to make use of all the other features of I2P (i.e.: BitTorrent, Gnutella, anonymous emails and websites) the whole package needs to be installed.
Warning: Due to basic translations and bugs, the internal I2P is slow and wastes lots of CPU. Instead, installing the I2P software is really suggested, in order not to use the internal I2P router of iMule.
