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: 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
