Running Multiple Eggdrops From One Directory
How can I run multiple Eggdrops from the one directory?
You don't need to install multiple copies of Eggdrop to run multiple instances. Instead, you can place multiple config files inside your single Eggdrop installation folder and run each config file
./eggdrop egg1.conf ./eggdrop egg2.conf ./eggdrop egg3.conf
At minimum, you'll want to make sure you change the nickname, userfile, channel file, pid file and listening ports/IPs for each Eggdrop you run; but you'll also probably want to do a more thorough scrub to change things like the botnet nicks, idents, or realname fields (among others!)
