Alright, to get a Ragnarok Arena dedicated server running, a few steps are needed. (Thanks to Valve's HLDS update tool.)
First, you NEED to download the HLDS Update Tool
First, install an Orange box game. Valve has made it easy on us, all you have to do is download "orangebox" from the command line. NOTE: If you've never set up a dedicated server before I recommend reading this.
TO DO THIS! Install the HLDS Update tool to whatever folder you want THAT. IS. NOT. IN. PROGRAM. FILES.
(I recommend C:\HLServer). Once it's installed open up a command prompt and go to the folder that you installed the tools to and type this:
hldsupdatetool -command update -game orangebox -dir .
This will create an "orangebox" folder and an "hl2" folder in the directory that you told it to download to.
Then, download the Ragnarok Arena dedicated server archive here: http://www.ragnarokarena.com/downloads/RA-Beta1-DedicatedServer.7z
Extract the "hlss3" folder into the "orangebox" directory where the "hl2" folder resides. You can then launch the srcds executable with the line -game hlss3. Be sure to set up your server.cfg in the hlss3/cfg directory.Linux:
