This is a tutorial on how to install a IRC Server, as well as remove the hard connection limit to allow over 1024 connections at one time.
What you will need:
A VPS with linux and a root account
IRCD Software (im using Unkn0wn's modded Ircd.) Found
HERE
Putty or some other SSH client, as well as a SSH FTP client. Im using FlashFXP Beta.
Ok now to start
Log into your vps with the root account with putty. If this is your first time logging into your server it will ask you to accept the SHA1 fingerprint. Just do it :)
Now that you are logged in, make sure that you have gcc, gcc-c++, and kernel-devel installed. Use your install command based on the OS you are using. I am using CentOS 5 so my install command is "yum install".
I would also install nano if it isnt already, its an easy text editor to use, also make sure the package "make" is installed too.
It will ask if you want to install, type Y and it will install.
