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

-* in your Pi's create a user <code>adduser<code> with same name as used in the [[XPUB Sandbox|Sandbox Pi]]

 <pre>
-* add your public ssh key to your username in the Pi (same as mentioned) to ~/.ssh/authorized_keys
+    user: psc
-There is a trick to do this with
+    Node name: ?XYZ?
-`cat ~/.ssh/id_rsa.pub | ssh local.pi.IP.addr "cat >> ~/.ssh/authorized_keys"`
