Install n2x-node Agent

The n2x.io platform provides a one-line command for the simplest and quickest way to install the n2x-node agent in Linux. You'll find this command readily available when you add a new node through the n2x.io webUI.

1. Download the latest release.

   curl -LO "https://dl.n2x.io/binaries/stable/latest/linux/amd64/n2x-node"
   

2. Validate the binary (optional).

   Download the n2x-node checksum file:

   curl -LO "https://dl.n2x.io/binaries/stable/latest/linux/amd64/n2x-node_checksum.sha256"
   

   Validate the n2x-node binary against the checksum file:

   sha256sum --check < n2x-node_checksum.sha256
   

   If valid, the output must be:

   n2x-node: OK
   

   If the check fails, sha256 exits with nonzero status and prints output similar to:

   n2x-node: FAILED
   sha256sum: WARNING: 1 computed checksum did NOT match
   

3. Install n2x-node and create its configuration file according to your needs.

   sudo install -o root -g root -m 0750 n2x-node /usr/local/bin/n2x-node
   sudo mkdir /etc/n2x
   sudo vim /etc/n2x/n2x-node.yml
   

   Configuration Options

   For detailed information and a complete list of configuration options, refer to the n2x-node configuration reference. These options allow you to customize your n2x-node agent for specific needs.

4. Create the n2x-node.service for systemd.

   sudo cat << EOF > /etc/systemd/system/n2x-node.service

   ExecStart=/usr/local/bin/n2x-node start
   Restart=always
   
   # Other restart options: always, on-abort, etc
   
   # The install section is needed to use
   
   # 'systemctl enable' to start on boot
   
   # For a user service that you want to enable
   
   # and start automatically, use 'default.target'
   
   # For system level services, use 'multi-user.target'
   
   [Install]
   WantedBy=multi-user.target
   EOF
   

5. Ensure the tun kernel module is loaded.

   sudo modprobe tun

The n2x.io platform provides a one-line command for the simplest and quickest way to install the n2x-node agent in Windows. You'll find this command readily available when you add a new node through the n2x.io web interface.

1. Open the Windows PowerShell as Administrator and create a folder for n2x.

   mkdir 'C:\Program Files\n2x'
   

2. Download the latest release into the n2x folder.

   curl -Uri "https://dl.n2x.io/binaries/stable/latest/windows/amd64/n2x-node.exe" -Outfile n2x-node.exe
   

3. Validate the binary (optional).

   Download the n2x-node.exe checksum file:

   curl -Uri "https://dl.n2x.io/binaries/stable/latest/windows/amd64/n2x-node.exe_checksum.sha256" -Outfile n2x-node.exe_checksum.sha256
   

   Validate the n2x-node.exe binary against the checksum file:

   • Using Command Prompt to manually compare CertUtil's output to the checksum file downloaded:

     CertUtil -hashfile n2x-node.exe SHA256
     type n2x-node.exe_checksum.sha256
     

   • Using PowerShell to automate the verification using the -eq operator to get a True or False result:

     $($(CertUtil -hashfile .\n2x-node.exe SHA256)[1] -replace " ", "") -eq $(type .\n2x-node.exe_checksum.sha256).split(" ")[0]
     

4. Download the wintun driver from https://wintun.net.

5. Unzip the wintun archive and copy the AMD64 binary wintun.dll to C:\Program Files\n2x.

6. Use an editor to create the n2x-node configuration file C:\Program Files\n2x\n2x-node.yml.

   Configuration Options

   For detailed information and a complete list of configuration options, refer to the n2x-node configuration reference. These options allow you to customize your n2x-node agent for specific needs.

7. Install the n2x-node agent as a Windows service.

   'C:\Program Files\n2x\n2x-node.exe' service-install
   

   Info

   The instructions below assume that the wintun.dll, n2x-node.exe and n2x-node.yml files are stored in C:\Program Files\n2x.

8. Start the n2x-node service.

   start-Service n2x-node
   

9. Check n2x-node service status.

   get-Service n2x-node
   

The n2x.io platform provides a one-line command for the simplest and quickest way to running the n2x-node agent in Docker. You'll find this command readily available when you add a new node through the n2x.io web interface.

Example usage:

docker run -d --restart=always \
  --net=host \
  --cap-add=net_admin \
  --device=/dev/net/tun \
  --name n2x-node \
  -v /etc/n2x:/etc/n2x:ro \
  ghcr.io/n2x-io/n2x-node:latest start

All artifacts are checksummed and the checksum file is signed with cosign.

1. Download the files you want and the checksums.txt, checksum.txt.pem and checksums.txt.sig files from the Releases page:

2. Verify the signature:

   cosign verify-blob \
       --cert checksums.txt.pem \
       --signature checksums.txt.sig \
       checksums.txt
   

3. If the signature is valid, you can then verify the SHA256 sums match with the downloaded binary:

   sha256sum --ignore-missing -c checksums.txt
   

Our Docker images are signed with cosign.

Verify the signatures:

COSIGN_EXPERIMENTAL=1 cosign verify ghcr.io/n2x-io/n2x-node
