How to put on mods in a minecraft server?(1.6.4)?

I'm playing with a bunch of friends, but none of us know how to make a modded server. I already did what I could with the Forge, but the mods i put in the "Mods" folder doesn't work. I installed forge in a brand new folder, changed the "server.txt" and the server works fine, except that the mods does not show. I put the mods in Zip/Rar, and just leave them and run "minecraftforge-universal-1.6.4-9.11.1.965-v164-pregradle"
I really wanted to play with them, the normal minecraft is getting kinda of boring.
The mods i tried to put in: http://www.skydaz.com/mocreatures-mod-installer-for-minecraft-1-6-4/

That is because they're client versions of the Mod and not the server version. The client version is to install the mods to your minecraft which are.exe (windows) or.dmg (mac) files. They install a minecraft profile to your launcher which contains the mod. The files that you put in your servers mod folder needs to be a.jar file or a zip folder containing the.jar file. I can't seem to find the server files for Mo' Creatures.

If you want Galacticraft (Moonquest) and a lot of better mobs/animals then I highly recommend downloading the ATlauncher and downloading the new Yogscast Complete Pack which has over 240 mods without the hassle of manually installing mods using Forge. It also lets you download the server files separately. - http://www.atlauncher.com/
