Hosting a starbound server on a seperate computer?

I own a (64 bit) sun server that is running debian. This computer does not have steam installed. I want to host a starbound server on it. I copied the files from the linux64 folder of my starbound installation to the server, but when I go to launch the server I get the following error:
Info: Creating Star::Root with 1 assets sources and config file: './starbound.config'

Code:

Info: Creating Star::Root with 1 assets sources and config file: './starbound.config'
Info: Loading Star::Assets from: '/assets'
Error: Fatal Exception Caught: AssetBackendException: Asset database /assets is missing
./starbound_server(_ZN4Star13StarExceptionC2ERKSs+0xfe) [0xa57f1e]

Do I have to copy my entire assets folder or something? I've tried a few things but nothing has helped

 

You need to copy everything in the root, except the windows, .app and the linux folder you are not using

 

Just to clarify I'm trying to launch the server, not the client,

 

keep your linux64 files but also copy the assets folder

 

thanks guys, got it working!
