Problem with Mods Forge

Hello, I just installed the MineOS plugin on my NAS running FreeNAS 11.2. I created a Forge Server and it works. I went to /var/games/minecraft/servers/servername and there i created a folder called “mods” where i put the mod World Edit. I have the mod also installed on my client and i have Forge client. But when i start up the server and connect. The mod doesn’t work. I don’t think it gets run. What can i do to fix it and get it running? Thanks.

I just found a post here telling me that i should pick the fore-universal.jar and that fixed my problem.
