dpsmeter with remote packet sniffing that provides a web overlay for lostark

LostArk Logger and Custom Web Overlay (Docker)

A fork of https://github.com/karaeren/LostArkLogger with the capability to remote log packets via winpcap for Docker and display the logger in a custom web overlay.

To display the overlay on top of Lost Ark, you can install the tabfloater extension. For a darker browser theme, you can install the Dark Reader extension.

---

Initial Setup (Windows)

We call the machine where you run Lost Ark the main computer.

Here are some options for where to run the Docker container containing the DPS meter:

1. On your main computer
2. On a Virtual Machine on your main computer
3. On a remote computer on the same network as your main computer

Evaluate your tolerance for risk (highest-to-lowest risk) and your tolerance for overhead (lowest-to-highest overhead). If you are having issues with option (2) or (3) and don't want to do option (1), you can try a Virtual Machine fork.

First step: Install Dependencies

This setup requires the following dependencies:

• Install Npcap on your main computer.
  • Make sure to have the option Install Npcap in WinPcap API-compatible Mode checked.
• Install Docker (Desktop)
  • You can reference this guide
• Install git

You will also want to open Windows PowerShell to run the commands in the following steps.

Second step: Clone Repository

Clone this repository on the computer you will run the DPS meter on by running the following command in PowerShell:

git clone https://github.com/therealhumes/la-dpsmeter.git

Third step: Setup rpcapd

First, run the following command to make sure windows does not block unsigned software from being installed:

Set-ExecutionPolicy -Scope LocalMachine -ExecutionPolicy RemoteSigned -Force

Second, run the following script from the la-dpsmeter directory to install rpcapd:

cd la-dpsmeter
.\bin\install-rpcapd.ps1

Fourth step: Configure config.yml

Open the config.yml found in the la-dpsmeter folder and update the p-cap-address line to your IP address.

You can get your local IP with the following command (src):

(
    Get-NetIPConfiguration |
    Where-Object {
        $_.IPv4DefaultGateway -ne $null -and
        $_.NetAdapter.Status -ne "Disconnected"
    }
).IPv4Address.IPAddress

Alternatively, you can run ipconfig in PowerSHell and pull the top local lan address.

Fifth step: Run Container

Start up Docker if it is not already running. You will have installed this in the first step.

Run the following command from the la-dpsmeter directory.

docker run -d --name la-dpsmeter --restart unless-stopped -v ${pwd}/config.yml:/app/config.yml -v ${pwd}/logs:/mnt/raid1/apps/'Lost Ark Logs' -p 1338:1338 ghcr.io/therealhumes/la-dpsmeter:main

Sixth step: Access Overlay

You can access the web overlay by opening the following url in your browser:

http://<dps-meter-machines-ip-address>:1338

If you are running the DPS meter on your main machine, this ip address will be the same as the fourth step.

Future Updates

To update the container (or to kill it/refresh it), delete the old container and re-run or update the existing image.

To delete an old container, you can run the following Docker command:

docker rm -f la-dpsmeter

To update the image, you have to pull the latest version of the docker image with the following command:

docker pull ghcr.io/therealhumes/la-dpsmeter:main

Then use the same run command from the fifth step.
