GMod Survival Help

[Jakester808]

Before I explain my issue, let me give you some info :
OS : Ubuntu 12.10 x86 Server Minimal
Runs on a Virtual Server environment with a dedicated VCPU and 1GB of RAM, 1Gbit/s Upload/Download

When installing the SRCDS and Steam/GMod I used this tutorial exactly :
http://maurits.tv/data/garrysmod/wiki/wiki.garrysmod.com/indexfd7a.html

Here is my Server.cfg :

Code:

// server name
hostname "Ventutous Games - Fast, Stable Servers"
"sv_defaultgamemode"     "Gmod Stranded"

// rcon passsword
rcon_password "*** -hidden"  

// server cvars

sv_logecho 1
sv_logfile 1
sv_log_onefile 0

// operation
sv_lan 0
sv_region 0

// execute ban files
exec banned_user.cfg
exec banned_ip.cfg

Here is my autoexec.cfg :

Code:

gamemode Gmod Stranded

And my server start script is :

Code:

#!/bin/bash
echo "Starting up Garry's Mod 10 server Startup Script"
sleep 5
screen -A -m -d -S gm10server ./srcds_run -console -game garrysmod +maxplayers 16 +map gms_rollinghills_daynight_b1.bsp +sv_defaultgamemode "Gmod Stranded" -autoupdate
echo "Initiated. Type screen -x to resume."

So essentially I'm trying to get GMod Survival game mode to run off of my server. But I'm blind as to how to add any game mode other then sandbox. No matter what I do, it defaults to sandbox.
The only success I've had thus far is loading the map.
The thing with GMod Survival is that I can't find a download link to the server version. Maybe its because I'm new to adding custom game modes to GMod Ubuntu dedicated servers.

Basically, I need someone to point out what I'm doing wrong. I've downloaded and added http://www.garrysmod.org/downloads/?a=view&id=57195
to my server and cant seem to get it to run. Its just sandbox. Every time.

So can someone help me out as to how to install a custom game mode like this, Or how to install stranded in general?

EDIT :
Even if someone can shed some light as to how I can host any custom gamemode in general would be great! All I can find are TF2, CS, DoD and MAYBE DarkRP. How do I go about making my .cfg and startup scripts to launch a different game mode? What are some things my server needs to run a custom game mode? Does "sv_defaultgamemode" point to a game mode folder?
I've spent the entirety of my day attempting to get it working, just need something =)

Regards,
Jake
