Dedicated Server Setup
This article covers the bare minimum for server setup. Additional guides are recommended!
What is a "listen" server?
A listen server is run through the game's software, it's functionality that's built in.
This is ideal if you need to host a temporary server for friends to join within your city or province/state.

What is a "dedicated" server?
A dedicated server is technicaly a server that is availiable all the time, day or night, 24/7, 365. To do this it has a dedicated machine to use.
Special hardware should be used to run a dedicated server the right way. However, since it's just another piece of software you could use a spare computer.

To get things started, we should talk about what these "external" and "internal" IP addresses are, and how they affect you.
You will probably have a DHCP server in your house/apartment. Most of the time this will be your router, but in some cases it could be something else. DHCP is a system that allows the router (or other device) to pass out internal IP addresses to other devices (such as your computer, laptop or tablet) that connect to it. Inside your network, all the devices talk to each other by using these internal addresses. Only devices inside your network can talk to others with these addresses - as they are reserved for use in LAN networks.
If your friend wanted to connect to your NMRiH server, they may see it having the ip 192.168.1.2. This is what you see too, but your friend will scream and kick at not being able to connect. Just like you, your friend will be using these internal addresses as well. The problem here is that they correspond to computers/devices on their network, so when they try to connect, their router will only search on their network for a device that has the 192.168.1.2 address. In order to solve this problem, this is where external ip addresses come in.
Your router is assigned a public (external) IP address by your ISP's modem so it can communicate to computers around the word. This public address is also used when someone wants to give you data (websites, game servers, etc.). You can tell your router to pass on information it gets on a "port" to a computer inside the network. This is done by specifying the IP of the machine on the network, and what port to send it to. The common term for this is called "Port Forwarding", as it forwards the port(s) to another computer/device. This article won't go into detail about how to do that, but a great place to start is http://www.portforward.com, which will show you how to port forward.
To play on the server you only need to have 27015 (UDP) open/forwarded. The server doesn't use TCP traffic on this port for gameplay and thus is recommended that you do not forward it.
Now remember reading before about DHCP? It will come back to haunt you sadly. Since there is a limited amount of internal IP addresses, the router will try free up internal IP address for use. It will do this by removing unused addresses. These include computers/devices that are not on. So if you happen to turn the computer off that hosts the server and another device connects, it is likely to take that address your computer had and thus breaking the port forwarding you did. In order to prevent this from happening, you will have to set a static IP for the machine (technically the machine's ethernet interface).
That should now all be clear, you may be wondering where to get your external/public IP from. There are many sites that show you it - even Google "What is my IP address". After obtaining it, send it to your friends.
Now, many will argue at why you only need 27015 (UDP) open. Why not 27015 (TCP) with all those other ports as well? The remote console (RCON) for the server runs on 27015 (TCP) and can lead to security issues and Denial of Service attacks (DoS). You should only allow the TCP traffic in if you know what you're doing. Other ports shown in other guides are not needed, and thus don't need to be opened.
Setting up a Dedicated Server
Dedicated servers are preferred if you want to ensure you get the best performance and flexibility. Most of the time, it's installed on a separate machine/computer where both it and the server are made available 24/7 (hence the term dedicated).
This section will outline setup and administration for the latest generation of Windows. Versions Server 2003, XP and lesser will not directly follow these steps.
You will require the core SteamCMD files. You can find them here: https://steamcdn-a.akamaihd.net/client/installer/steamcmd.zip
Extract the files to a directory other then the steam client. Now open a command prompt to that directory and run steamcmd.
- This is usually fixed by checking "Automatically detect settings" in IE (Internet Explorer) through the lan settings in the Internet option menu.
- 1. Open Internet Explorer (IE)
- 2. Click on Tools > Internet Options
- 3. Click on the "Connections Tab"
- 4. At the Bottom, you should see "Local Area Network (LAN) Settings".
- 5. Check the first box "Automatically detect settings"
- 6. Hit OK, and apply. Try running the SteamCMD again, if it still doesn't work. try lowering your "Internet Security level zone" to medium or lower. You can find that in the "Security" tab in "Internet Options".
SteamCMD will update if required each time it executed. Now to download the NMRiH dedicated server software, Type the following into SteamCMD and hit enter after each line. (be mindful of the spaces)
- login anonymous
- force_install_dir .\nmrih_ds\
- app_update 317670
Now you should be able to navigate to the srcds.exe file and use: srcds.exe -console -game nmrih -insecure +map nmo_chinatown
Windows - Persistent Dedicated Server Login
The following command can be used to provide your dedicated server with a persistent login, which allows users to "favorite" your server as it uses a registered domain name's DNS entry to find your server.
The following steps will need to be taken:
- 1. Go to Steam website: http://steamcommunity.com/dev/registerkey and login to your steam account.
- 2. Input either a domain name (www.domain.com) or your public facing IP address as the domain name then click 'Register'.
- 3. Steam will display your Steam Web API key.
- 4. Input the Steam Web API key in this webtool and select "No More Room In Hell" in the "Game" field.
- 5. A "login_token": "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX" will be provided. Copy/Save the string between the quotation marks, XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX.
- 6. Open autoexec.cfg in you nmrih cfg folder and add 'sv_setsteamaccout XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX' without quotes. Save the file.
- 8. Start your server.
- 9. Server console now shows: Assigned persistent gameserver Steam ID [G:1xxx].
No More Room in Hell server is available on Linux. These are brief instructions on how to install and start a server.
For further assistance take a look at the Server Hosting Forum. http://www.nomoreroominhell.com/forums/index.php?showforum=70
Create a username for your server.
Chose a directory to install the server.
Create a directory for steamCMD.
mkdir steamcmd cd steamcmd
tar -xvzf steamcmd_linux.tar.gz
Create a directory for the server files,
Run the following command to download the server. You will need a Steam username and password to authenticate with steamCMD.
./steamcmd.sh +login username password +force_install_dir "/home/nmrihserver/serverfiles" +app_update 317670 validate +quit
The No More Room in Hell server requires 32-bit library's to run. You are required to install extra packages to run this server.
sudo apt-get install lib32gcc1
dpkg --add-architecture i386
apt-get update && apt-get install lib32gcc1
yum install glibc.i686 libstdc++.i686
Other 64-bit distros will have similar requirements to this. It is recommended that you seek out documentation or forums posts regarding 32-bit libraries.
Starting the server
to run the server use the following command.
./srcds_run -game nmrih +map nmo_broadway -maxplayers 8 -autoupdate
There are various command line parameters available for the server. A complete list of parameters are available from the Valve Wiki.
No More Room in Hell requires GLIBC_2.15 or above to run. If your distro does not meet this requirement you may get the following error.
./srcds_nmrih: /lib/i386-linux-gnu/i686/cmov/libm.so.6: version `GLIBC_2.15' not found
To fix this download the following file to the directory with srcds_nmrih included within it.
srcds_nmrih will use this updated version of libm.so.6 instead of the OS version. This problem commonly effects distros with a long life cycle such as RHEL and CentOS.
You can use these commands on listen servers as well as dedicated servers. Enter the command/cvar you want to use, and the value (if it requires one).
While on a listen server, open the developer console with the ~ key.
