Other HUB nodes

Steps to add a new Node to HUB

• in your Pi's create a user adduser with same name 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)

* add your public ssh key to your username in the Pi (same as mentioned) to ~/.ssh/authorized_keys 
There is a trick to do this with 
`cat ~/.ssh/id_rsa.pub | ssh local.pi.IP.addr "cat >> ~/.ssh/authorized_keys"` 

* install Tinc on the Pis Instructions can be found here https://pzwiki.wdka.nl/mediadesign/Tinc

* Add your chosen Node name and IP to https://pzwiki.wdka.nl/mediadesign/HUB#IP_allocation
    * Student project IPs last number should have 3 digits, last one is Simon's 10.0.1.103, so you can start from there 

* disable ssh to your pi with password (allow ssh key only)
ensure:
    * you laptops ssh public key is in your pi ~/.ssh/authorized_keys: `cat  ~/.ssh/authorized_keys`
     * you can login to the Pi with ssh key:  ssh username@pi.ip.add -i ~/.ssh/id_rsa 
edit /etc/ssh/sshd_config: `sudo nano /etc/ssh/sshd_config` 
and uncomment the line: #PasswordAuthentication no
to: PasswordAuthentication no
reload ssh: `sudo systemctl reload ssh`

On this side:  @Andre

* I will need to give invitation links to each node https://pzwiki.wdka.nl/mediadesign/HUB#Adding_a_new_thing
* ask gnd to associate your username+pub key to the Pi IP:
