(UTC)XDCC ("Xabi DCC" a.k.a "eXtended DCC") was initially a script written in 1994 for ircii by Xabi. This script extends the ircii DCC command.
Now XDCC refers to IRCbots running file sharing programs. XDCC bots serve one or more usually large files for download using the DCC protocol. Though it is widely understood to be a protocol by which illegal content (usually MP3s or other forms of warez) can be listed and, subsequently, downloaded it is also used in the legal sense. Many XDCC servers are hacked.
Frequently, FXP groups utilize connections with large upstream bandwidth (e.g. Colleges and Universities around the world) in order to mass distribute warez releases (usually ISO images compressed using the RAR compression algorithm, with other files (NFO and SFV) packaged together as a tar file). Note that warez release groups (comprising the top tier in the warez scene hierachy) do not support XDCC.
XDCC is quickly gaining popularity over older methods of computer piracy such as newsgroups and fserve. Unlike peer-to-peer transfers, XDCC is often hosted on connections with massive upstream bandwidth, the most popular dumps (server computer with massive amounts of pirated software) are usually connected to sites with 100Mbit (or more) connections. Often times the XDCC servers are also running FTP servers which facilitate illegal uploading of materials to the bots. Common programs used for this are ServU (an FTP server that can be installed as a Daemon as well as some sort of rooting tool.
To use XDCC one can send a private message (query) or send a CTCP command to a bot using an IRC client. The user can ask a bot what files it has by private messaging "xdcc list" to the bot. However, this feature is often disabled as to not attract too much attention. When a user wants to download a packet, or file, from a bot the user would type something such as "xdcc send " to the bot. The bot will either start sending the user the packet or the bot will place the user in a queue, or in a line, and force the user to wait their turn.
* /msg xdcc send (Requests a pack number from the bot.) * /ctcp xdcc send (If the above is disabled, try this.) * /msg xdcc list (Requests a list of packs available from the bot.) * /ctcp xdcc list (If the above is disabled, try this.) * /msg xdcc remove (This only works via msg.)
