Establishing a modpack server

[Dean OathN]

Hi,

I am fairly new to Tekkit and recently found a modpack that I really enjoy. I'd like to play it with my friends sometime, but I am not sure how setting up a server with a public modpack works, or if you can do that. I would appreciate it if somebody could direct me to where I can find out how to set up a server with a public modpack, or if somebody could simply tell me that would be nice too. 

I apologize in advance if this isn't where this topic should go, or if this question has already been answered.
