RCON (Remote CONnection) is the method pavlov servers can be controlled from outside of VR. When a server is brought online, an email is sent to the owner with the RCON credentials to connect remotely. RCON can be accessed at: <nowiki>http://pavlovrcon.com/</nowiki>  
RCON (Remote Console) is the method with which Pavlov VR servers can be controlled from outside of VR. It does not allow for reading server log messages.

== RCON Commands ==
 
=== Placeholders ===
Values in [square brackets] are placeholders and must be replaced, or will be replaced by the server in a reply.
 
[UniqueID] - Player ID (eg. [https://steamid.io/ SteamID64] (PCVR), Oculus Username (Shack))
 
[GameMode] - See [[Setting up a dedicated server#Configuring Game.ini|Gamemodes table]] and [[Gamemodes]]
 
[TeamID] - 0 for blue, 1 for red, if there are teams
 
[VehicleID] - See [[Vehicles]]
 
[MapName/ID] - See [[Default Maps|Default maps]] or find the Map ID on Mod.io and append it to "UGC" (Example: https://mod.io/g/pavlov/m/mcdonalds has Resource ID <code>2804322</code>, the MapID to use would be <code>UGC2804322</code>)
 
[SkinID] - See [[ItemIDs#Skins|Skins]]
 
[RoleID] - See [[ItemIDs#TTT Roles (Case Sensitive)|TTT Roles]]
 
[ItemID] - See [[ItemIDs|Items]]
 
[True/False] - Either "True" to enable or "False" to disable
 
[Amount] - A number indicating an amount of something
 
=== Reply format ===
All command replies are formatted as JSON and inherit this base format:
{
"Command": "[The command name]",
"Comment": "[An optional comment about the command]",
"Successful": "[True/False]"
}
Comment will not exist if the command does not output a comment.
 
Additional command output is added to the above format. The Example Reply column below only contains this additional command output.
 
Often, commands will contain a field with its own name and a boolean value. This is a very inconsistent value. For example in <code>SetMaxPlayers</code>, if the amount is set to the same as the current slot count, <code>Successful</code> will be <code>true</code> but <code>SetMaxPlayers</code> will be <code>false</code>. However for <code>SwitchTeam</code> for example, if a player is switched to the same team they are already in, <code>SwitchTeam</code> will be <code>true</code> anyway.

Full URLs (eg. http://...) do not work.


=== Connecting to RCON ===
The balance table contains the values for the prices in the buy wheel, how much money is gained from which actions and how much damage is dealt by each weapon including damage falloff and more.


Make sure whatever port you used is open in your firewall for TCP connections. Connections are simple TCP port/telnet style connections.

|SetPin
|[Optional PinNumber]
|Sets the server pin to the specified pin number.
Supplying a pin number locks the server so that player have to enter a pin to join.


A good first place to start is the RCON web interface run by ArcticVR. You do this at http://pavlovrcon.com/.  
Not supplying a pin number unlocks the server so that players do not have to enter a pin.


If you want private control of your server, you will need to do a bit more work for it. At the simplest, using netcat (nc) or telnet as described above will give you basic access to all commands
PinNumber can be any whole number between 1 and 9999 and may not contain leading zeroes such as <code>0001</code> which would get trimmed to <code>1</code>.


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.
Setting the pin to <code>0</code> or <code>0000</code> does not remove the pin but sets it to <code>0</code>.
<pre>  
#!/bin/bash
function slowcat(){ while read; do sleep .05; echo "$REPLY"; done; }
cat  $1 | slowcat | nc {ip address} {port}

== Connecting to RCON ==
<hr>
RCON uses a simple UTF-8 TCP text stream allowing for a multitude of ways to connect.


'''There is a very brief example above
=== Authentication ===
but it was not very detailed so i wanted to add a more detailed explanation'''
After connecting to RCON, the first message sent is by the server requesting the RCON password to be transmitted.


be aware that connecting and disconnecting a lot can hurt server performance
For this, the server sends a 10 byte message "<code>Password:</code> " (including the trailing space) to the client.


first you need to make a shell script
The client is expected to reply with the password as lowercase hex representation of the MD5 checksum of the password.
<pre>nano /home/steam/test.sh</pre>


<pre>#!/bin/bash
No line feed or carriage return character must be transmitted as part of the password.
function slowcat(){ while read; do sleep .15; echo "$REPLY"; done; }
cat $1 | slowcat | nc {SERVER IP} {SERVER RCON PORT}</pre>


now exit and save the test.sh
If the password is correct, the server will reply with <code>Authenticated=1\r\n</code> or if the password was incorrect, the reply will be <code>Authenticated=0\r\n</code>.


here will will make a batch file that will just hold the rcon password and cmds we want to issue
'''Example'''


<pre>nano /home/steam/batch</pre>
Authentication using the password "hello test".
<pre>{RCON PASSWORD CONVERTED TO MD5 HASH}
> Password:
{RCON CMD}
< 7a6d667ea5ed4467c017b2ed6ea07e78
{RCON CMD}
> Authenticated=1\r\n
Disconnect</pre>


here the first line has to be the rcon password converted to MD5 HASH
=== Sending commands and receiving replies ===
https://www.md5hashgenerator.com/
Any data sent to the server and terminated by a line feed character will be interpreted as a command and executed.
then each line after that u can use any rcon commands
the last line must be disconnect


now we need to give the sh permissions to run
This is followed by the server sending the corresponding command response in JSON format with new lines being indicated by a line feed character
<pre>sudo chmod +x /home/steam/test.sh</pre>


to run the bash script
The response is terminated with a carriage return and line feed.  
<pre>./home/steam/test.sh /home/steam/batch</pre>


so to run the script we need to ./ the .sh then after a space we need to pass the batch
'''Example'''


=== Rcon access from within VR ===

PavlovRconWebserver, pavlov-vr-rcon and pavlov_rcon_tcl have been designed to be accessible within VR using virtual desktop view.
== Tools for connecting to RCON ==


=== Third party hosted tools ===
The easiest way to access RCON is to use a third party hosted tool. These are websites that take the RCON connection information and provide an RCON web interface.


'''pavlov_rcon_tcl''': This is a tool designed to run on your desktop for access within VR
'''Warning''': These tools may not be open source and can steal RCON passwords! Because they are hosted by third parties, it is impossible to verify that they do not.

=== Third party local tools ===
These are programs that are downloaded and ran locally to provide an RCON interface.


'''PavlovRconWebserver''' is an interface designed to be usable from everywhere all the time. (also in VR over desktop view)
'''Warning''': If a tool is not open source it is not easily possible to verify that it does not steal RCON passwords. It is recommended to only use open source tools that can be verified.

=== Third party self hosted tools ===
These are services that need to be self hosted.


If you do plan on using this tool, we recommend asking for help on the official Discord or http://discord.spitzen.solutions, or contacting the creator on the Github page (devinspitz) for the latest info on how to use it. Failing to do so will likely result in you breaking your servers.

=== RCON access from Discord ===
==== Telnet ====
Telnet seems to prematurely flush the buffer when entering the password, causing authentication to fail.


For the ultimate in both control and complexity of setup, use the open-source '''pavlov-bot'''. This is a discord bot that will listen for commands in your discord 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####) and enhanced "all" and team based commands. Has support for flushing non-registered players from server. Advanced features to include alerting when servers are kicking off, team killing player kick/ban and large server (PUSH/RUSH/TankTDM) player balance (count) control.  
=== Libraries ===
These are libraries for developers to interface with RCON.


For '''shack''' users it has been updated to support Oculus ids and map aliases, so is fully functional for both server versions. See Readme.md for shack specific tweaks.

==== Tips on developing apps to use RCON ====
It should be avoided to open a new connection for each command. It may cause performance issues.


'''Horde''' also offers a Discord Bot to grant RCON permissions to friends in Discord, and run commands from specific channels. Invite the Horde Bot to your Discord server with this link:
It should be avoided to send multiple commands directly one after the other without a delay of 100ms. It may cause commands to be dropped.

=== Tips on developing apps to use RCON ===
Commands are not executed during a map change.
What is important if you are issuing commands using a program at high frequency is that you open one connection and put all of the commands through that open connection with a small (.1 sec is fine) delay. What you don't want to do is open a new connection for each command or shove all of the commands through super fast. First causes performance issues and the second dropped commands.

RCON (Remote Console) is the method with which Pavlov VR servers can be controlled from outside of VR. It does not allow for reading server log messages.

RCON Commands

Placeholders

Values in [square brackets] are placeholders and must be replaced, or will be replaced by the server in a reply.

[UniqueID] - Player ID (eg. SteamID64 (PCVR), Oculus Username (Shack))

[GameMode] - See Gamemodes table and Gamemodes

[TeamID] - 0 for blue, 1 for red, if there are teams

[VehicleID] - See Vehicles

[MapName/ID] - See Default maps or find the Map ID on Mod.io and append it to "UGC" (Example: https://mod.io/g/pavlov/m/mcdonalds has Resource ID 2804322, the MapID to use would be UGC2804322)

[SkinID] - See Skins

[RoleID] - See TTT Roles

[ItemID] - See Items

[True/False] - Either "True" to enable or "False" to disable

[Amount] - A number indicating an amount of something

Reply format

All command replies are formatted as JSON and inherit this base format: 

{
	"Command": "[The command name]",
	"Comment": "[An optional comment about the command]",
	"Successful": "[True/False]"
}

Comment will not exist if the command does not output a comment.

Additional command output is added to the above format. The Example Reply column below only contains this additional command output.

Often, commands will contain a field with its own name and a boolean value. This is a very inconsistent value. For example in SetMaxPlayers, if the amount is set to the same as the current slot count, Successful will be true but SetMaxPlayers will be false. However for SwitchTeam for example, if a player is switched to the same team they are already in, SwitchTeam will be true anyway.

Connecting to RCON

RCON uses a simple UTF-8 TCP text stream allowing for a multitude of ways to connect.

Authentication

After connecting to RCON, the first message sent is by the server requesting the RCON password to be transmitted.

For this, the server sends a 10 byte message "Password: " (including the trailing space) to the client.

The client is expected to reply with the password as lowercase hex representation of the MD5 checksum of the password.

No line feed or carriage return character must be transmitted as part of the password.

If the password is correct, the server will reply with Authenticated=1\r\n or if the password was incorrect, the reply will be Authenticated=0\r\n.

Example

Authentication using the password "hello test". 

> Password: 
< 7a6d667ea5ed4467c017b2ed6ea07e78
> Authenticated=1\r\n

Sending commands and receiving replies

Any data sent to the server and terminated by a line feed character will be interpreted as a command and executed.

This is followed by the server sending the corresponding command response in JSON format with new lines being indicated by a line feed character

The response is terminated with a carriage return and line feed.

Example

Tools for connecting to RCON

Third party hosted tools

The easiest way to access RCON is to use a third party hosted tool. These are websites that take the RCON connection information and provide an RCON web interface.

Warning: These tools may not be open source and can steal RCON passwords! Because they are hosted by third parties, it is impossible to verify that they do not.

Third party local tools

These are programs that are downloaded and ran locally to provide an RCON interface.

Warning: If a tool is not open source it is not easily possible to verify that it does not steal RCON passwords. It is recommended to only use open source tools that can be verified.

  • pavlov_rcon_tcl: Python based UI which is designed to be usable from within VR. Standalone executable. Requires editing of configuration files.
  • pavlov-vr-rcon: node.js based web UI which is designed to be usable from within VR. Requires node.js.

Third party self hosted tools

These are services that need to be self hosted.

Warning: If a tool is not open source it is not easily possible to verify that it does not steal RCON passwords. It is recommended to only use open source tools that can be verified.

  • PavlovRconWebserver: Feature-rich all-in-one hosting solution.
  • PPSC: Pterodactyl-based feature-rich server management software. Requires the servers to run through Pterodactyl.
  • pavlov-bot: A bot that allows for using RCON through Discord.

Direct connect

Since the RCON protocol is plain text TCP, direct connection terminals can be used to connect to RCON.

Netcat

Telnet

Telnet seems to prematurely flush the buffer when entering the password, causing authentication to fail.

Libraries

These are libraries for developers to interface with RCON.

Tips on developing apps to use RCON

It should be avoided to open a new connection for each command. It may cause performance issues.

It should be avoided to send multiple commands directly one after the other without a delay of 100ms. It may cause commands to be dropped.

Commands are not executed during a map change.
