Setting up a dedicated server

If you don't want to go through the hassle yourself and want to pay for a hosting service Arctic VR provides a server hosting service and is trusted in the community. https://www.arctic-vr.com/server-hosting

There are no Windows binaries, this guide is exclusively for Ubuntu/Debian/Debian-like Linux distros. Possible to run with other distros, but some of the commands won't work and you will need to know enough to figure out the software install of dependencies on your own.

This guide assumes you know the basics of using a bash terminal: ssh'ing into a server, running bash commands, editing text files, etc.

If you have no experience using bash, maybe start [here][1]

If you are new to linux and accessing your server from Windows, highly suggest using MobaXterm as your SSH client as that can make required editing of text files easier using built in editor instead of the native linux command line editors.

Minimum Specs

Believe (but haven't gotten confirmation) that 64bit OS is required. Ubuntu 18.04 x86_64 and Ubuntu 19/04 amd64 and Ubuntu 20.04 are confirmed working. Ubuntu 15.04 x86 is known to fail to install using this guide

2GB RAM 2.3Ghz Dual Core CPU for a 10-15 player server (depends on the Maps)

Prerequisites

Install dependencies and create the `steam` user. (You only need to do this once):

sudo apt update && sudo apt install -y gdb curl lib32gcc1 && sudo useradd -m steam

Login as the steam user. (You will need to do this each time you connect to your server):

sudo su -l steam -s /bin/bash

Install Steam:

mkdir ~/Steam && cd ~/Steam && curl -sqL "https://steamcdn-a.akamaihd.net/client/installer/steamcmd_linux.tar.gz" | tar zxvf -

Install the Pavlov Server (You will need to to do this each time there is a Pavlov Server update):

cd ~/Steam && ./steamcmd.sh +login anonymous +force_install_dir /home/steam/pavlovserver +app_update 622970 +exit

For those intending to host the PC BETA you will need to install this specific version of the server as opposed to the one above. If you are hosting for Standard PC, skip this step

cd ~/Steam && ./steamcmd.sh +login anonymous +force_install_dir /home/steam/pavlovserver +app_update 622970 -beta beta_server +exit



For those intending to host for Shack (Quest) you will need to install this specific version of the server as opposed to the one above. If you are hosting for PC, skip this step

cd ~/Steam && ./steamcmd.sh +login anonymous +force_install_dir /home/steam/pavlovserver +app_update 622970 -beta shack +exit



Make the PavlovServer script executable. (You only need to do this once):

chmod +x ~/pavlovserver/PavlovServer.sh

Server Configuration

Before starting the server we need to configure it. Start by creating a symlink and some directories:

ln -s /home/steam/Steam/linux64/steamclient.so /home/steam/pavlovserver/Pavlov/Binaries/Linux/ mkdir -p /home/steam/pavlovserver/Pavlov/Saved/Logs mkdir -p /home/steam/pavlovserver/Pavlov/Saved/Config/LinuxServer

Configuring Game.ini

Create a new Game.ini file using following command to open an editor and copy/paste the following block into it then save it

nano /home/steam/pavlovserver/Pavlov/Saved/Config/LinuxServer/Game.ini

[/Script/Pavlov.DedicatedServer] bEnabled=true ServerName="My dedicated server" MaxPlayers=50 bSecured=true bCustomServer=true bWhitelist=false RefreshListTime=120 LimitedAmmoType=2 TickRate=90 TimeLimit=60 Password=0000 MapRotation=(MapId="UGC1668673188", GameMode="SND") MapRotation=(MapId="datacenter", GameMode="SND") MapRotation=(MapId="sand", GameMode="DM")

bEnabled - whether the server appears in the server list (unconfirmed)

- whether the server appears in the server list (unconfirmed) ServerName - name it will be listed as. (approx 35 chars max)

- name it will be listed as. (approx 35 chars max) MaxPlayers - See suggested specs for limits

- See suggested specs for limits bSecured - enabled Valve Anti-Cheat (VAC)

- enabled Valve Anti-Cheat (VAC) bCustomServer - activates some new modding tools (save and http functions)

- activates some new modding tools (save and http functions) bWhitelist - Only allow users in whitelist.txt to join

- Only allow users in whitelist.txt to join RefreshListTime - sets how often the running server checks for updates in ban/whitelist/mod files

- sets how often the running server checks for updates in ban/whitelist/mod files LimitedAmmoType - sets limited ammo mode (experimental) 0-2 unlimited,generic,specific

- sets limited ammo mode (experimental) 0-2 unlimited,generic,specific TimeLimit - sets time limit for each map

- sets time limit for each map TickRate - sets the server tickrate. (so far minimum stable seems around 50 and max around 120)

- sets the server tickrate. (so far minimum stable seems around 50 and max around 120) Password - PIN number for server

- PIN number for server MapRotation - you can add multiple of these. The MapId must be “UGC” followed by the map ID. you can find the map id in the URL of the steam workshop page.

Available game modes as of 24 of August, 2020: SND, TDM, DM, GUN, ZWV, (TTT - Shack Only)

Maps running a Custom Game Mode (TTT (on PC), BR, Duel, etc.) don't care which GameMode you chose, as long as it isn't Shack TTT, which will always override.

UGC###### are for custom maps from steam workshop (PC Only). Find the map you want in the workshop. This is the URL for Mirage (https://steamcommunity.com/sharedfiles/filedetails/?id=1661803933). To put Mirage in your rotation UGC1661803933 would be the correct MapId

Firewall/Port forwarding

Using the default settings there are two UDP ports (7777, 8177) that need to be allowed to access the server either by firewall setup or port forwarding.

You may also need to allow Pings (ICMP) for the server's true latency to appear in the master list.

If you are running multiple servers and have set additional ports (see http://wiki.pavlov-vr.com/index.php?title=Dedicated_server#Running_multiple_servers_on_one_host) then you need to allow access to the defined port plus the port 400 higher. So if you use 7000 as your port, then UDP 7000 and 7400 need to be open

If you have setup rcon via RconSettings.txt (below) then that port also need to be allowed access via TCP

If you are running Shack/Quest and want to have maps that are downloadable from your server, your server ports (ex. 7777 & 8177) must also be open via TCP

Shack Maps (Quest)

If you try to use the steps above to add maps for Shack, youll run into issues very quickly. This is because Shack has no affiliation to Steam, and therefore cannot use Steam Workshop maps like above. In the future, these steps will apply to PC servers as well, allowing a server to hold the map itsself, instead of offloading to Steam.

To get started, first create the directory to hold the maps

mkdir -p /home/steam/pavlovserver/Pavlov/Saved/maps

You can use any number of methods to move the map files onto the server, but ill go over the two simplest, starting with a GUI approach

Download and install CyberDuck onto your "home" PC (Whatever PC you use for access to the server, but not the server itsself): https://cyberduck.io/

Next, download and unzip your map of choice from https://www.pavlovquest.com/ , im going to use Cheeto's WW2 Items test (http://www.mediafire.com/file/emyt9bs1z9u9ykw/SVR_Cheeto_Items.zip/file ) for this example, you do what you like

In the top left corner, open a connection, set the connection type to SFTP, and fill in the rest of the information. User will be root, password is whatever you set the root pw as (toor in Ubuntu by default)

In the directory dropdown (itll say /root) go back to /

home/steam/pavlovserver/Pavlov/Saved/maps

Follow the directories until we arrive back at our "maps" folder

Drag and drop the unzipped map folder into the main window, in this case itll be SVR_Cheeto_Items

Hit Allow

Youll now see a folder named SVR_Cheeto_Items, and within it should be nothing but 3 files. If there is another folder in it, move this folder to the maps directory, otherwise the server wont work. The 3 files (2 PAK one JSON) should be in home/steam/pavlovserver/Pavlov/Saved/maps/SVR_Cheeto_Items, no more, no less.

To actually play the map, youll need to add the map's folder name to your Game.ini. This replaces the MapID section, so for our example it would be

MapRotation=(MapId="SVR_Cheeto_Items", GameMode="TDM")

And thats all! Disconnect CyberDuck from your server before playing, otherwise youll have difficulty joining.





Adding Shack Maps over Command Line Interface

A bit more complicated, but adding maps over CLI has its benefits

First, CD to the maps directory you made above

cd ~/pavlovserver/Pavlov/Saved/maps

Download the map files from whatever you use to upload them. To do this, you can either use curl or wget

curl -O insertURLhere

To keep with the Items example:

curl -O http://download2275.mediafire.com/7pucyqp8opdg/emyt9bs1z9u9ykw/SVR_Cheeto_Items.zip

Next, unzip the file. If this next step errors out, saying the command is unknown, switch back to the root user (su root), and install unzip (sudo apt install unzip), then return here.

unzip SVR_Cheeto_Items.zip

Now finish like before by adding the map to your Game.ini

vim /home/steam/pavlovserver/Pavlov/Saved/Config/LinuxServer/Game.ini

MapRotation=(MapId="SVR_Cheeto_Items", GameMode="TDM")





Admin/Moderator list (optional)

If you add moderators to your server, they will have an "admin panel" in their menu which will allow them to:

kill player

teleport to player

kick player

ban player (note this ban is only in memory and clears when server restarts. If you want it to be permanent, use blacklist.txt file (below) and/or Rcon ban command)

rotate to next map

nano ~/pavlovserver/Pavlov/Saved/Config/mods.txt

Example Mod List:

76541198397498572 #Optional Comment: Player name 76541198397498573 #Some Other Player

ArcticVR Admin Menu

Arctic-VR Offers a more advanced In-Game Admin menu that is exclusive to their hosting service. Features include:

Switch Maps+Modes

Teleport Players to Players

Change Player Skins

Control Player Buying+Cash

Spawn Items

Clean up corpses + guns

Spawn Bots

Spawn Items for other players

Control Teams + Balance/Shuffle Teams

ResetSND

And More

You can read more about the ArcticVR admin menu on their website: https://www.arctic-vr.com/server-admin-menu

Blacklist/Whitelist (optional)

If you want the ability to ban players or only allow players based on their steamID you can use blacklist.txt and whitelist.txt to define these players

Both files should be written in ~/pavlovserver/Pavlov/Saved/Config/ and have same format as Mod list above.

Note that blacklist.txt has to exist if you want to use Rcon ban and whitelist.txt is only used if bWhitelist=true in Game.ini

Currently bans actioned by admins in-game are only held in memory and not written to blacklist.txt. As such, they go away when server is rebooted.

Steam ID finder: https://steamidfinder.com/lookup/

You want to enter in the steamID64 format.

This tool can convert or lookup IDs: https://steamid.io/

If you are looking for a steamID of a player that has been on your server recently this is technique to find them:

grep -i playername ~/pavlovserver/Pavlov/Saved/Logs/* | grep TicketValidation

Hosting at home

When hosting at home there are additional requirements regarding networking: Your router has to support port-forwarding and hair-pinning, techniques necessary to allow your server to be found and to talk back to the client. please see https://en.wikipedia.org/wiki/Port_forwarding and https://en.wikipedia.org/wiki/Hairpinning for more info and google for these terms in addition to your router model to find guides on how to enable/configure it properly. If you have modern Router, it may have these features already enabled, in this case you just have to configure port-forwarding.

A second challenge to hosting at home is CGNAT (Carrier grade NAT: https://www.a10networks.com/blog/carrier-grade-nat/). Just like NAT on your home network that has to be gotten around w/ port-forwarding, CGNAT breaks the ability of external connections to be made back to your server, but the controls are solely in your ISPs hands. Sometimes if you ask, you can be removed from CGNAT pools and/or assigned a static IP. CGNAT rollouts are becoming very common now, so if your server worked then doesn't allow connections now, your ISP may have made this change.

You can check whether you’re on a CGNAT network by visiting a Web site such as ipaddress.com or whatsmyip.com and comparing the IP address listed to the public/WAN IP address assigned to your Internet gateway. To find your gateway’s public IP address, check the status page in the administrative interface. If the two IP addresses differ, you’re likely on a CGNAT network. If so, this problem must be resolved before you go any further.

Not understanding these requirements and configuration is a frequent cause of failed setups and questions in discord. Don't skip this if you are trying to host from home

There are serious security implications of hosting this software at home. None of the devs are security experts and there has been no security review of the code. You are opening up your system to the world and publicity advertising this fact. Expect that any system hosting this software is open to compromise from the Internet and act accordingly. If your router offers a DMZ network, use it. Consider hosting on a cloud based server and think twice before running this software on any system that contains data you care about or has access to networks and computers you care about.

Starting the server

cd ~/pavlovserver && ./PavlovServer.sh

That's it, your server will be automatically broadcast to the master server! :)

Note that when you close your terminal, the server will go down. See the "supervisors" section below for how to prevent this.

Supervising the server using systemd

Running ./PavlovServer.sh in your interactive shell is easy, but the server will shut down when you close your terminal. If you want to run the server in the background, you'll want to run it under a supervisor. There are many options, ranging from the simple (nohup, screen or tmux), to the more robust (supervisord, systemd).

Systemd is running by default on Ubuntu Linux, so we'll use that here.

To run the server as a systemd service, create the file /etc/systemd/system/pavlovserver.service (as root) by typing "sudo nano (or other editor you want to use) /etc/systemd/system/pavlovserver.service" with the contents

[Unit] Description=Pavlov VR dedicated server [Service] Type=simple WorkingDirectory=/home/steam/pavlovserver ExecStart=/home/steam/pavlovserver/PavlovServer.sh # XXX the server will often crash on round end/map change with a segfault # until dave hires more programmers, just restart the server every time RestartSec=1 Restart=always User=steam Group=steam [Install] WantedBy = multi-user.target

Change the user or paths as appropriate. After saving the service file, to start, restart, stop, or monitor the server:

sudo systemctl start pavlovserver sudo systemctl restart pavlovserver sudo systemctl stop pavlovserver sudo systemctl status pavlovserver

To view the logs:

sudo journalctl -u pavlovserver # to live-tail the logs sudo journalctl -u pavlovserver -f

If you want to run the pavlov server as soon as your server boots (e.g. a VPS you turn on and off), add pavlov as a startup service:

sudo systemctl enable pavlovserver

Here's some executables you can create to help, after setting these up they should be the only commands you need to run on your server. Descriptions on what they are, and how to install and use them are in the comment blocks.

#!/bin/bash -e # Copy txt of this script to /usr/bin/pav-edit # chmod a+x /usr/bin/pav-edit # usage: pav-edit # stops the server, edits the config, updates the server, starts the server, then tails the logs # doesn't need to be run as the "steam" user # does assume you've setup systemd as per the wiki echo "stopping server..." sudo service pavlovserver stop echo "opening config..." sudo vim /home/steam/pavlovserver/Pavlov/Saved/Config/LinuxServer/Game.ini echo "updating server binary..." cd /home/steam/Steam sudo -u steam ./steamcmd.sh +login anonymous +force_install_dir /home/steam/pavlovserver +app_update 622970 +exit echo "starting server..." sudo service pavlovserver start echo "tailing logs..." /usr/bin/pav-logs echo "pav-edit complete"

#!/bin/bash -e # Copy txt of this script to /usr/bin/pav-logs # chmod a+x /usr/bin/pav-logs # usage: pav-logs # tails the logs tail -f -n1000 /home/steam/pavlovserver/Pavlov/Saved/Logs/Pavlov.log | grep -v 'Sending heartbeat to masterserver'

Rcon Overview and Commands

To enable Rcon access create config file "/home/steam/pavlovserver/Pavlov/Saved/Config/RconSettings.txt"

Example RconSettings.txt file:

Password=ChangeThisPassword Port=9100

You must specify a port for the Rcon server to use as well as a Password (use a different port per sever instance if running multiple server instances off the same hardware)



Ban/Unban

If you want Ban/Unban to work create file /home/steam/pavlovserver/Pavlov/Saved/Config/blacklist.txt writable by user running server.



Commands:

Help -Returns the full list of commands Ban {SteamID} -Bans the player from the server (adds them to blacklist.txt) Kick {SteamID} -Kicks the player from the server Unban {SteamID} -Unbans the player from the server (trys to remove the unique id from blacklist.txt) RotateMap -Rotates to the next map in the game.ini SwitchMap {MapName/ID} {GameMode} -Switches to the map/gamemode specified, ex "SwitchMap DataCenter TDM" or "SwitchMap UGC1080326389 DM" SwitchTeam {SteamID} {TeamId} -Switches the specified players team GiveItem {SteamID} {ItemId} -Give the specified player the Item GiveCash {SteamID} {CashAmt} -Give the specified player cash GiveTeamCash {TeamId} {CashAmt} -Gives all members of the teamId cash InspectPlayer {SteamID} -Returns information about the player specified (PlayerName, Cash, KDA, TeamId etc) RefreshList -Returns a list of players on the server (unique/steamId) ServerInfo -Returns information about the server (ServerName, CurrentMap, PlayerCount/MaxPlayerCount etc) Disconnect -Disconnects the player from Rcon ResetSND -Resets the match back to round 1 keeping the same teams SetPlayerSkin {SteamID} {SkinId} -Sets the skin for the specified player (clown, prisoner, naked, farmer, russian, nato) SetLimitedAmmoType {0-2} -Sets the limited ammo type for the duration of the match

Make sure whatever port you used is open in your firewall for TCP connections.

To test connecting to the rcon port use netcat:

nc {ip address} {port}

echo -n password | md5sum

For the password use the md5 hash of the password in the file (this may change in the future). You can get this using

If successful you should get an Authenticated=1 reply

At the simplest, using netcat (nc) as described above will give you basic access to all commands

If you want to batch commands (i.e. for moving players on to teams and triggering ResetSnd) the following script can be useful to call a pre-written batch files of commands. Call with your batch file as the first argument to the script. The file should have one command per line with first line being the hashed password as above.

#!/bin/bash function slowcat(){ while read; do sleep .05; echo "$REPLY"; done; } cat $1 | slowcat | nc {ip address} {port}

Example batchfile:

8b96753b29612d8c98d6b696140b5d9f ResetSnd Disconnect

At the next level of complexity and utility you can checkout either of the two commandline programs available on github. Both of these provide a simple interface to Rcon via interactive text console interface:

https://github.com/vankruptgames/PavlovVR-Rcon

https://github.com/d0n/pavlovadm



For the ultimate in both control and complexity of setup, use pavlov-bot. This is a discord bot that will listen for commands in your discord channel and execute them. Supports all Rcon commands with handy features such as discord role based authentication and authorisation, player, map and team aliases (No more SteamIDs or UGC####). For shack users it has been updated to support EOS ids, so should be fully functional for both server versions

https://github.com/makupi/pavlov-bot



PavlovRconWebserver is an interface designed to be usable from everywhere all the time. (also in VR over desktop view) Feature video

Features: SSH tunnel your rcon connection, mutliserver administration, most rcon commands from the wiki, map(realtime steam workshop maps)/item selector, control over browser(Android,IOS,Windows,Linux,etc), Roles: Admins/Users(Moderators)

https://github.com/devinSpitz/PavlovRconWebserver

Rcon access from within VR

PavlovRconWebserver is being designed to be accessible within VR using virtual desktop view. There is also a workable method using either built in access to your windows desktop via SteamVR or other tools like OVRDrop. Details are a bit complex, but the general overview is as follows:

On your gaming rig install Cygwin (https://cygwin.com/install.html). This is a well known opensource program to give you linux tools on your windows system. During install, there is an option to install additional packages. Find the "nc" package to install netcat.

Once cygwin is installed, open up a cygwin terminal window and test access to the server using nc as described above. Once that is proven working, create wrapper script given above in /usr/local/bin/rcon_file.sh (within Cygwin) and a batchfile as described above and test. A very handy one for SND allows you to call ResetSnd so that once teams are sorted the game can start.

Create a desktop shortcut that calls Cygwin, then your script and batchfile with following: C:\cygwin64\bin\mintty.exe -i /Cygwin-Terminal.ico /bin/bash -l -c "/usr/local/bin/rcon_file.sh ~/rcon_reset.txt" where rcon_reset.txt is your batchfile. Test this shortcut. It may be then handy to pin this to taskbar for easier access when viewing virtual desktop from within VR.

If all goes well, you can now trigger a set of commands from within VR after a quick glance to your desktop.

Advanced Server Administration

Running multiple servers on one host

Make multiple server installs by defining a separate install dir for each server.

Run each server with a unique port. eg: ./PavlovServer.sh -PORT="Desired Port"

The Server will use the Desired Port and the Port 400 above (Example: You choose 8200 as Port. So Port 8600 will be used as well)

Ensure the ports are forwarded and opened in your firewall

To duplicate directories:

be in the steam home folder

cp -R pavlovserver pavlovserver1

/home/steam/pavlovserver1/PavlovServer.sh -PORT=[Desired Port]

Troubleshooting

To run the server without outputting the heartbeat:

./PavlovServer.sh | sed '/heartbeat/d'

To monitor the logs (without heartbeat) from another terminal:

tail -f -n10000 /home/steam/pavlovserver/Pavlov/Saved/Logs/Pavlov.log | grep -v 'Sending heartbeat to masterserver'

Check your CPU Clock Speed with:

lscpu | grep MHz

Map wont load (kicks to datacenter)

try deleting all the downloaded workshop maps with:

sudo rm -rf /tmp/workshop/7777/content/555160/*

sudo rm -rf /tmp/workshop/7777/content/555160/whatever-UGC

Server kicks all players at end of SND game with "Connection Lost"

for all maps orfor specific map

This looks to be a bug related to PavTV. If you don't care about PavTV, you can stop this behaviour by either firewalling off egress to port 80 of 147.75.74.75 or blackhole the traffic with

sudo route add 147.75.74.75 gw 127.0.0.1 lo

This IP address may change, so if this stops working raise the issue in #pc-custom-servers

Getting Help

There's a #pc-custom-servers channel on the official Pavlov Discord - https://discord.gg/Pavlov-VR. Lots of helpful people there!
