DCC

Direct Client Connection

DCC uses direct TCP connections between the clients taking part to carry data. There is no flood control, so packets can be sent at full speed, and there is no dependance on server links (or load imposed on them). In addition, since only the initial handshake for DCC conections is passed through the IRC network, it is impossible for Operators with cracked servers to spy on DCC messages.

The initial socket for a DCC connection is created by the side that initiates (Offers) the connection. This socket should be a TCP socket bound to INADDR_ANY, listening for connections.

The following DCC connection types are known to IRCII:

Type	Purpose				Argument CHAT	To carry a secure conversation	the string "chat" SEND	To send a file to the recipient	the file name
