10.33 Direct Client Connections

What is DCC?

DCC or Direct Client Connection is a protocol that IRC clients can use to communicate directly with each other, bypassing the IRC server. The reason for this is to form a faster, more stable and direct connection thru which users can transfer files, or send private messages. Note that AmIRC has its own set of Highly Optimized DCC protocols built-in, and does not require external DCC utilities.

DCC File Transfers

The most common use of DCC is for transferring files between two clients. The initiating client will send a message through the IRC server, telling the receiver that a connecton is requested. At this time, the receiver will either accept or reject the offer for the connection. If the receiver accepts the connection, the initiating client will proceed to send the information directly to the receiver. If the connecton is refused, the initiating client will simply timeout the attempt to connect.
