Adding new Node to HUB

For graduation project or some Special issues, the XPUB HUB Node: Sandbox might not be adequate, add new nodes can be added the XPUB Hub Tinc network

This page describes how to do it


Steps to add a new Node to HUB

For Pi user (with sudo/root)

Use this template to fill in all the fields and you go through the process

    user: psc
    Node name: ?XYZ?
    IP: 10.0.0.???
    url: https://hub.xpub.nl/?XYZ?
    ssh public key:
    ?????????@??


In your Pi: (or other Unix machine connected to the internet) create a user adduser with same username as used in the Sandbox Pi

  • Keeping it the same as in the sandbox - will make things easier for us and gnd (no need to give him again your public ssh key)

In your Pi: Add your laptop's user's public ssh key to your Pi user account in ~/.ssh/authorized_keys

In your Pi: Install Tinc on the Pi. The instructions can be found in the Tinc page

Add your chosen Node name and IP to HUB

  • Student project IPs last number should have 3 digits

In your Pi: Disable ssh with password (allow ssh with sshkey only) ensure:

  • you laptops ssh public key is in your Pi ~/.ssh/authorized_keys: cat ~/.ssh/authorized_keys
  • edit /etc/ssh/sshd_config: sudo nano /etc/ssh/sshd_config</code
  • uncomment the line: #PasswordAuthentication no
  • to: PasswordAuthentication no
  • reload ssh: sudo systemctl reload ssh

= For XPUB Staff (with sudo in XVM)

  • create a Tinc invitation links to each node HUB#Adding_a_new_thing
  • ask gnd to associate the Pi user's username + ssh pubkey with the Pi IP
