Adding new Node to HUB
For graduation projects 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#IP_allocation
- Student project IPs last number should have 3 digits
In your Pi: Add your laptop's ssh public key
- getting and copying your laptop's ssh public key
cat ~/.ssh/id_ed25519.pub
- add it to Pi's ~/.ssh/authorized_keys:
sudo nano ~/.ssh/authorized_keys
In your Pi: Disable ssh with password (allow ssh with sshkey only):
- edit sshd_config file:
sudo nano /etc/ssh/sshd_config
- uncomment the line:
#PasswordAuthentication no
- so it becomes:
PasswordAuthentication no
- so it becomes:
- 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
