ngIRCd is a portable IRC daemon written from scratch. It is easy to configure,
supports server links (even with original ircds) and runs on hosts with changing
IP addresses (such as dial-in networks). Currently supported platforms are AIX,
A/UX, Darwin/Mac OS X, FreeBSD, HP-UX, IRIX, Linux, NetBSD, SunOS/Solaris, and Windows with Cygwin.
