DCC was way to send files and chat without having IRC server in the
|
||
|
|
between. It's not very common nowadays and what is done nowadays is
|
||
|
|
uploading images etc. to social media services or web servers or using
|
||
|
|
other file transfer protocols.
|
||
|
|
|
||
|
|
Here are some reasons to not use it:
|
||
|
|
|
||
|
|
* There is no proper standard or if there is, no one follows it, all
|
||
|
|
clients speak their own dialects and may be unable to communicate with
|
||
|
|
other clients. Not all clients even implement the same features.
|
||
|
|
* NAT and firewalls break it
|
||
|
|
* As DCC requires port on sending/hosting side, it must be opened in
|
||
|
|
firewall and if there is NAT which there is in most of situations
|
||
|
|
nowadays, the port must be forwarded. Most of average users have
|
||
|
|
no idea how to do the latter if even the first.
|
||
|
|
* The only place where most of people see it is spam. The only thing lately
|
||
|
|
where people have seen is two attacks which @grawity has documented

## Disabling DCC
|
||
|
|
|
||
|
|
This depends on your client and I am only able to give instructions for
|
||
|
|
three:
|
||
|
|
|
||
|
|
* WeeChat: "`/plugin unload xfer`" and "`/set weechat.plugin.autoload *,!xfer`"
|
||
|
|
* The option in second command can be also be used to not automatically
|
||
|
|
load other plugins, I personally use `/set weechat.plugin.autoload alias,exec,irc,perl,python,script,trigger,logger`.
|
||
|
|
The `*,!xfer` simply means load everything else than xfer.
|
||
|
|
* HexChat: "`/ignore *!*@* DCC`"
|
||
|
|
* ZNC & clients behind it: "`/znc *controlpanel addctcp $me DCC`"
