charybdis - 4.1.1-1+b1 main

Charybdis is a highly scalable IRC server which presently implements
the IRCv3.1 client protocol with some additional components of
IRCv3.2. Development of charybdis began in 2005 as a proposed
replacement to freenode’s hyperion ircd, designed for use by any
network, with roots in ircd-ratbox and ircu. Over time, charybdis has
developed, tested and demonstrated many of the features commonly seen
in modern IRC networks.

Interesting features that Charybdis has include:
.
* SASL support — charybdis was the first IRC server to implement SASL
support, resulting in the IRCv3 SASL standards.

* Augmented banlist criteria through “extbans”
* Channel forwarding (channel mode +f)
* Optional hostname/IP cloaking (through modules, either usermode +h or

and robustness

Many of the largest networks in the world use charybdis-based IRC
