Help With PVPGN Server Setup On FreeBSD

by Henrik Larsen 40 views

Hey guys! So, you're looking to get your PVPGN server up and running on FreeBSD, huh? That's awesome! Setting up a private game server can be a really rewarding experience, especially when you get to share it with your friends. I understand you've managed to install it, but now you're stuck on how to actually start the service. Don't worry, we've all been there! Getting those first steps right can sometimes feel like navigating a maze.

Let's break this down and get your server online. First off, you mentioned trying /build/src/bnetd and ./bnetd. These are definitely on the right track, but there might be a few things we need to check to make sure everything is running smoothly. So, let's dive deep into the wonderful world of PVPGN and FreeBSD, and I'll guide you through the process. I'll make sure we cover everything from the basics to some of the more common pitfalls you might encounter. Think of this as your friendly guide to PVPGN mastery!

Understanding PVPGN and FreeBSD

Before we jump into the nitty-gritty commands, let's take a moment to understand what we're dealing with. PVPGN (Private Virtual Pocket Gaming Network) is essentially a server emulator. It allows you to host your own private servers for classic Blizzard games like Diablo, Warcraft II, and StarCraft. Think of it as creating your own little corner of the internet where you and your buddies can relive the glory days of these games, free from the official Battle.net restrictions. It's perfect for setting up custom game rules, playing with mods, or just having a more controlled environment.

Now, let's talk about FreeBSD. This is a powerful and stable Unix-like operating system. It's known for its robustness and security, which makes it a fantastic choice for hosting servers. However, like any Unix-based system, it has its own quirks and ways of doing things. Getting comfortable with the command line is key to mastering FreeBSD, but don't let that intimidate you! Once you get the hang of it, you'll find it's an incredibly efficient and flexible environment. In this guide, we'll walk through the commands step by step, so you'll not only get your server running, but you'll also start building your FreeBSD skills.

When you combine PVPGN with FreeBSD, you get a powerful and customizable setup for your private game server. But, it's crucial to make sure everything is configured correctly. We need to verify that all the dependencies are met, the configuration files are properly set up, and the server is starting in the way it's supposed to. This might sound like a lot, but we'll take it one piece at a time.

Initial Checks and Common Issues

Okay, let's start with some initial checks. These are the common culprits that often trip people up when setting up PVPGN on FreeBSD. First things first, let's make sure you're in the right directory. The commands you tried, /build/src/bnetd and ./bnetd, suggest you're trying to run the bnetd executable directly. That's the main PVPGN server process, and it's good you're focusing on that. But, before we execute it, we need to make sure we're in the correct location within the file system.

Typically, after compiling PVPGN from source (which I assume you've done since you mentioned /build/src), the bnetd executable would be located in a specific directory. This directory usually contains other important files, like the configuration files (bnetd.conf) and other supporting executables. If you try to run bnetd from the wrong directory, it might not be able to find these essential files, leading to errors or the server simply not starting. To navigate the file system, you'll use commands like cd (change directory) and ls (list files). These are your best friends when working on the command line.

Another common issue is file permissions. In Unix-based systems like FreeBSD, files have permissions that dictate who can read, write, and execute them. If the bnetd executable doesn't have execute permissions, you won't be able to run it. To check the permissions, you can use the ls -l command. This will give you a detailed listing of files and their permissions. If you find that bnetd doesn't have execute permissions, you can use the chmod command to change them. This might sound technical, but it's a fundamental part of working with FreeBSD, and we'll walk through the specific steps shortly.

Navigating the File System

So, let's get practical. First, we need to figure out where your PVPGN installation actually lives. If you followed the standard installation procedure, it's likely in a directory like /usr/local/pvpgn or /opt/pvpgn. But, if you compiled from source in your home directory, it might be in a pvpgn folder there. Let's start by checking your home directory. Open your terminal and type the following commands:

cd ~
ls -l

The cd ~ command takes you to your home directory. The ls -l command then lists all the files and directories in your home directory in a detailed format. Look for a directory named pvpgn, or anything similar. If you find it, that's a good sign! It means your PVPGN source code and potentially the compiled executables are located there.

If you don't find it in your home directory, don't panic! We can try looking in the more common installation locations. Try these commands:

cd /usr/local
ls -l

Look for a directory named pvpgn in the /usr/local directory. If you find it, great! If not, we'll try one more place:

cd /opt
ls -l

Check for a pvpgn directory in /opt. If you still can't find it, you might need to think back to where you extracted the PVPGN source code or where you specified the installation directory during the compilation process. It's like a little treasure hunt, but once we find the right directory, we're one step closer to getting your server running!

Once you've located the main PVPGN directory, cd into it. Then, ls -l again. You should see a bunch of files and subdirectories. Look for a directory named src or build. This is where the compiled executables are likely to be.

Checking File Permissions

Okay, so you've found the directory with the compiled executables. Now, let's check those file permissions. cd into the src or build directory (whichever one contains bnetd) and run the following command:

ls -l bnetd

This will give you a detailed listing for the bnetd file specifically. The output will look something like this:

-rwxr-xr-x  1 youruser  yourgroup  123456  Jul 20 10:00 bnetd

Let's break this down. The first part, -rwxr-xr-x, is the permission string. It tells us who can do what with this file. The first character indicates the file type (a - means it's a regular file). The next three characters (rwx) are the permissions for the file owner (the user who owns the file, in this case, youruser). The next three (r-x) are the permissions for the group that owns the file (yourgroup), and the final three (r-x) are the permissions for everyone else.

What we're looking for is an x in the owner's permissions (rwx). This means the owner can execute the file. If you don't see an x, it means the file is not executable, and that's likely why you couldn't start the server. To fix this, we'll use the chmod command. Run the following:

sudo chmod +x bnetd

The sudo command allows you to run commands with administrator privileges (you'll likely be prompted for your password). The chmod +x bnetd command adds execute permissions to the bnetd file. Now, if you run ls -l bnetd again, you should see the x in the owner's permissions.

Running bnetd Correctly

Alright, we've navigated the file system, checked permissions, and made sure bnetd is executable. Now, let's try running it again. But, this time, we're going to do it with a slightly different approach. Instead of just running ./bnetd, we're going to specify the full path to the executable. This can help avoid any confusion about the current working directory.

So, assuming you're in the directory containing bnetd (the src or build directory we found earlier), run the following command:

./bnetd

If that doesn't work, try running it with sudo:

sudo ./bnetd

If bnetd starts successfully, you should see some output in the terminal, indicating that the server is initializing. It might display messages about loading configuration files, listening for connections, and so on. If you see this, congratulations! Your PVPGN server is likely up and running.

Configuration Files: bnetd.conf

However, just because the server is running doesn't mean it's fully configured. PVPGN relies on a configuration file called bnetd.conf to define various server settings, such as the server name, MOTD (message of the day), game ports, and more. This file is crucial for customizing your server and making it your own.

The bnetd.conf file is usually located in the same directory as the bnetd executable, or in a subdirectory named conf or etc. Let's navigate back to the main PVPGN directory (where you found the src or build directory) and look for it. Run these commands:

cd ..
ls -l

Look for a directory named conf, etc, or anything similar. If you find one, cd into it and list the files:

cd conf  # or etc, whichever you found
ls -l

You should see a file named bnetd.conf (or something similar). This is the file we need to examine and potentially modify.

The bnetd.conf file is a plain text file, so you can open it with any text editor, such as vi, nano, or ee (FreeBSD's built-in text editor). For example, to open it with nano, you would run:

sudo nano bnetd.conf

The sudo is important here because you might need administrator privileges to modify the file. Once you have the file open, you'll see a bunch of settings and options. Don't be intimidated! We'll go through some of the key ones.

Key Configuration Options

Let's highlight some of the most important settings in bnetd.conf that you'll likely want to customize:

  • server_name: This sets the name of your server, which will be displayed in the game client's server list. Choose a name that's descriptive and inviting!
  • motd: This is the Message of the Day, which is displayed to players when they connect to your server. Use it to welcome players, announce events, or provide important information.
  • realm: This defines the realm name for your server. Players will need to select this realm in their game client to connect to your server.
  • game_port: This sets the port number that the server listens on for game connections. The default is usually 6112, but you can change it if needed. Make sure this port is not blocked by your firewall.
  • maxusers: This sets the maximum number of players that can connect to your server simultaneously. Adjust this based on your server's resources and your desired player capacity.
  • admin_accounts: This allows you to define administrator accounts for your server. These accounts have special privileges, such as the ability to ban players or manage the server.

When you modify the bnetd.conf file, be sure to save your changes. If you're using nano, you can press Ctrl+O to save and Ctrl+X to exit. After making changes to the configuration file, you'll need to restart the bnetd server for the changes to take effect.

Starting bnetd in the Background

So, you've got bnetd running, but you've probably noticed that it's tied to your terminal session. This means if you close the terminal, the server will shut down. That's not ideal! We want the server to run in the background, so it keeps running even when you're not actively using the terminal. There are a couple of ways to achieve this.

One common method is to use the nohup command. This command allows you to run a process that will continue to run even after you log out. To use nohup, you would run:

nohup ./bnetd &

Let's break this down. The nohup command tells the system to ignore the hangup signal, which is sent when you close the terminal. The ./bnetd is the command to start the server. The & at the end tells the system to run the process in the background.

When you run this command, you'll likely see a message like:

appending output to nohup.out

This means that the output of the bnetd server (any messages it prints) will be written to a file named nohup.out in the current directory. This is useful for checking for errors or monitoring the server's activity.

Another way to run bnetd in the background is to use a process manager like screen or tmux. These tools allow you to create virtual terminal sessions that can be detached and reattached later. This is particularly useful if you want to interact with the server while it's running in the background.

For example, to use screen, you would first install it (if it's not already installed) using your FreeBSD package manager (e.g., pkg install screen). Then, you would run:

screen ./bnetd

This will create a new screen session and start bnetd within it. You can then detach from the session by pressing Ctrl+A followed by Ctrl+D. This will leave the server running in the background.

To reattach to the screen session later, you can run:

screen -r

This will bring you back to the terminal where bnetd is running, allowing you to interact with it.

Creating a Startup Script

Running bnetd manually or using nohup or screen is fine for testing, but for a production server, you'll want a more reliable way to start the server automatically when the system boots. This is where startup scripts come in. FreeBSD uses a system called rc.d to manage services, and we can create a script to automatically start bnetd when the system starts.

Creating a startup script involves a few steps. First, you'll need to create a script file in the /usr/local/etc/rc.d directory. The script file should have a descriptive name, like bnetd. You'll need to use sudo to create and edit files in this directory, as it requires administrator privileges.

sudo nano /usr/local/etc/rc.d/bnetd

Now, you'll need to add the script code to the file. This code tells the system how to start, stop, and restart the bnetd server. A basic startup script for bnetd might look something like this:

#!/bin/sh

# PROVIDE: bnetd
# REQUIRE: NETWORKING
# BEFORE: DAEMON
# KEYWORD: shutdown

. /etc/rc.subr

name="bnetd"
rcvar="bnetd_enable"

command="/path/to/your/bnetd/executable/bnetd"

load_rc_config $name

: ${bnetd_enable:="NO"}

pidfile="/var/run/${name}.pid"

run_rc_command "$1"

Let's break down this script:

  • #!/bin/sh: This specifies the shell interpreter for the script (in this case, sh).
  • # PROVIDE, # REQUIRE, # BEFORE, # KEYWORD: These are special comments that provide information to the rc.d system. They specify the service name, dependencies, and other attributes.
  • . /etc/rc.subr: This includes a set of functions that simplify writing rc.d scripts.
  • name="bnetd": This sets the service name.
  • rcvar="bnetd_enable": This sets the variable that controls whether the service is enabled.
  • command="/path/to/your/bnetd/executable/bnetd": This is the most important part! You need to replace /path/to/your/bnetd/executable/bnetd with the actual path to your bnetd executable. This is the command that will be executed to start the server.
  • load_rc_config $name: This loads the configuration variables for the service.
  • : ${bnetd_enable:="NO"}: This sets the default value for bnetd_enable to NO, meaning the service is disabled by default.
  • pidfile="/var/run/${name}.pid": This specifies the file where the process ID (PID) of the bnetd server will be stored.
  • run_rc_command "$1": This runs the appropriate command (start, stop, restart, etc.) based on the argument passed to the script.

After adding the script code, save the file. Now, you need to make the script executable:

sudo chmod +x /usr/local/etc/rc.d/bnetd

Next, you need to enable the service by adding the following line to /etc/rc.conf:

sudo nano /etc/rc.conf

Add this line to the file:

bnetd_enable="YES"

Save the file and exit. Now, you can start the service manually using the following command:

sudo service bnetd start

If everything is configured correctly, the bnetd server should start. You can check its status using:

sudo service bnetd status

And you can stop it using:

sudo service bnetd stop

With the startup script in place, bnetd will now start automatically whenever your FreeBSD system boots. This ensures that your server is always available, even after a reboot.

Firewall Configuration

One crucial aspect of running a server that we haven't touched on yet is firewall configuration. A firewall is a security system that controls network traffic, allowing only authorized connections to pass through. FreeBSD has a built-in firewall called pf (Packet Filter), which is very powerful and flexible.

By default, pf is usually configured to block all incoming connections except those explicitly allowed. This is a good security practice, but it means that your PVPGN server won't be accessible from the outside world unless you configure pf to allow connections on the appropriate ports.

The first step is to determine which ports your PVPGN server is using. The main port is usually 6112, but you might have configured other ports in bnetd.conf for specific game types or features. You'll need to allow traffic on all the ports that your server is using.

The pf configuration file is located at /etc/pf.conf. You'll need to edit this file with administrator privileges:

sudo nano /etc/pf.conf

The pf.conf file is divided into sections. The most important section for our purposes is the rules section, where you define the rules for allowing or blocking traffic. You'll need to add a rule to allow incoming TCP and UDP traffic on the ports that your PVPGN server is using.

A basic rule to allow traffic on port 6112 might look like this:

pass in proto tcp to any port 6112
pass in proto udp to any port 6112

This rule tells pf to allow incoming TCP and UDP traffic to any IP address on port 6112. You'll need to add similar rules for any other ports that your server is using. For example, if you're using port 4000 for a specific game, you would add:

pass in proto tcp to any port 4000
pass in proto udp to any port 4000

After adding the rules, you need to save the pf.conf file and reload the firewall configuration. You can do this with the following commands:

sudo pfctl -f /etc/pf.conf
sudo pfctl -e

The pfctl -f /etc/pf.conf command loads the new configuration from the file. The pfctl -e command enables the firewall. If you make a mistake in the configuration file, the pfctl -f command will likely report an error. If this happens, carefully review your configuration and correct any errors before trying to reload it.

To disable the firewall, you can use the command:

sudo pfctl -d

However, it's generally not recommended to disable the firewall entirely, as it leaves your server vulnerable to attacks. It's much better to configure the firewall to allow only the necessary traffic.

Testing the Connection

So, you've got your PVPGN server running, configured the firewall, and set up a startup script. Now, it's time to test the connection and make sure everything is working as expected. This is a crucial step, as it verifies that players can actually connect to your server.

The first thing you'll want to do is test the connection from within your local network. This means connecting to the server from a computer on the same network as the server itself. This will help you rule out any issues with your external network configuration or firewall.

To connect to your server, you'll need the IP address of the server machine. If you're connecting from the same machine, you can use the loopback address, which is always 127.0.0.1. If you're connecting from another machine on the same network, you'll need to find the server's local IP address. You can do this by running the ifconfig command on the server machine. Look for the interface that's connected to your local network (usually em0 or re0) and note the IP address listed next to inet.

Once you have the IP address, you can configure your game client to connect to it. The exact steps for this will vary depending on the game you're playing, but typically you'll need to enter the IP address and port number of your server in the game's connection settings. Make sure you're using the correct port number (usually 6112, unless you've configured something different in bnetd.conf).

If you can connect to the server from your local network, that's a great sign! It means that the server is running correctly and that there are no local network issues preventing connections. However, you'll also want to test the connection from outside your network, to make sure that players from the internet can connect to your server.

To do this, you'll need your server's public IP address. This is the IP address that your internet service provider (ISP) assigns to your network. You can find your public IP address by visiting a website like whatismyip.com from a computer on your network.

Once you have your public IP address, you can try connecting to your server from a computer outside your network. This might involve asking a friend to try connecting, or using a virtual private server (VPS) or other remote machine to test the connection.

If you can't connect to your server from outside your network, there are a few things you'll want to check:

  • Firewall Configuration: Double-check your firewall configuration to make sure that you've allowed incoming traffic on the correct ports. Remember that you might need to configure both the FreeBSD firewall (pf) and your router's firewall.
  • Port Forwarding: If your server is behind a router, you'll need to configure port forwarding to forward traffic from your public IP address to the server's local IP address. The exact steps for this will vary depending on your router model, but typically you'll need to access your router's configuration interface and create a port forwarding rule for the PVPGN ports.
  • ISP Restrictions: Some ISPs block certain ports, which might prevent players from connecting to your server. If you suspect this is the case, you can try using a different port or contacting your ISP for assistance.
