charybdis

Charybdis is an IRCv3 server designed to be highly scalable. It implements IRCv3.1 and some parts of IRCv3.2.

It is meant to be used with an IRCv3-capable services implementation such as Atheme or Anope.

necessary requirements

A supported platform
A working dynamic load library.
A working lex. Solaris /usr/ccs/bin/lex appears to be broken, on this system flex should be used.

For SSL/TLS client and server connections, one of:
- OpenSSL 1.0 or newer
- LibreSSL
- mbedTLS
- GnuTLS
For certificate-based oper CHALLENGE, OpenSSL 1.0 or newer. (Using CHALLENGE is not recommended for new deployments, so if you want to use a different TLS library, feel free.)
For ECDHE, OpenSSL 1.0.0 or newer is required. RHEL/Fedora and derivatives like CentOS will need to compile OpenSSL from source, as ECC/ECDHE-functionality is removed from the OpenSSL package in these distributions.

Please read doc/index.txt to get an overview of the current documentation.
The files, /etc/services, /etc/protocols, and /etc/resolv.conf, SHOULD be readable by the user running the server in order for ircd to start with the correct settings. If these files are wrong, charybdis will try to use 127.0.0.1 for a resolver as a last-ditch effort.
FREEBSD USERS: if you are compiling with ipv6 you may experience problems with ipv4 due to the way the socket code is written. To fix this you must: "sysctl net.inet6.ip6.v6only=0"
SOLARIS USERS: this code appears to tickle a bug in older gcc and egcs ONLY on 64-bit Solaris7. gcc-2.95 and SunPro C on 64bit should work fine, and any gcc or SunPro compiled on 32bit.
SUPPORTED PLATFORMS: this code should compile without any warnings on:
- FreeBSD 10
- Gentoo & Gentoo Hardened ~x86/~amd64/~fbsd
- RHEL 6 / 7
- Debian Jessie
- OpenSuSE 11/12
- OpenSolaris 2008.x?
- Solaris 10 sparc.

Please let us know if you find otherwise.
It probably does not compile on AIX, IRIX or libc5 Linux.
