I'm trying to find information on how to build my own IRC server. If anyone could point me in the right direction it would be greatly appreciated.

Thanks

Build your own server? In what respect - Hardware or software?

software, the hardware is in place

You will require an IRCD and an OS (obviously). A popular IRCD is Unreal, coded by our very own codemastr which you can get here.

Install it, configure it, link it with other servers and I believe you're done

I won't be linking mine to any other servers, will this cause me any unexpected trouble?

Shouldn't do.
