Direct client-to-client
Direct Client-to-Client ( DCC ) is a widely used protocol that is supported by many IRC clients . It is used to establish a connection independent of the IRC server , which can be used for exchanging files as well as for chatting .
DCC connections can be initiated in two different ways:
- The most common method consists of initiating a DCC session with CTCP (Client-to-Client-Protocol). A CTCP request is sent from one user to another via the IRC network.
- Another way to initiate a DCC session is to connect a client directly to a DCC server. Using this method, the two parties don't even need to be connected on an IRC network.
DCC includes the following services:
- CHAT: Allows users to converse ( chat ) with each other over a DCC connection . The data traffic runs directly between the two users and not via another server (for example the IRC network).
- WHITEBOARD: Is an extension of DCC CHAT and enables you to draw together or to make sketches with the help of an interactive whiteboard .
- SEND: Allows one user to send files (directly) to another.
- FSERVE: DCC fserve is a service of a DCC server that allows a user to display or download a list of available files. The process is comparable to a text-based FTP client. (See also XDCC .)
Many IRC clients (for example XChat , mIRC or Nettalk ) already contain DCC and thus also all common options that DCC offers.
