Setting up my raspberry pi

In my computer:

SD card

1. Format for FAT32 (I used disk utility on mac. Format to MS_DOS). Use more than 8gb, mediawiki can become heavy.

2. Flash ISO to SD card (Raspbian Buster Light, https://www.raspberrypi.org/downloads/raspbian/ ) with a mounter (I've used etcher https://www.balena.io/etcher/ )

With raspi connected to power, internet, screen and keyboard:

01 Default login

Login: pi

Password: raspberry

02 SSH config

   $ cd /boot

   $ sudo touch ssh

   $ sudo reboot

03 Check IP address

   $ hostname -i

Response: 192.0.0.0

04 My keyboard wasn't working properly.

I had to change language of keyboard to US instead of UK.

   $ sudo raspi-config

   Localisation Options

   Change Keyboard Layout

   Choose US

After using the keyboard I changed back to UK to avoid errors.

05 Change hostname

   $ ssh pi@192.0.0.0

   $ sudo raspi-config

   Choose item no. 2 on the menu: Network Options

   Rename hostname to: newhostname

   $ reboot

06 Add user

   $ sudo adduser name

07 Add new user to sudo

   $ sudo adduser name sudo

08 You should be able to login with:

   $ ssh name@newhostname

09 I had an error with known hosts. I removed cached key on my computer:

   $ ssh-keygen -R 192.000.0.000

10 Remove default pi user

   $ sudo deluser pi

10 Use key-based authentication:

10.1 Add .ssh keys to RPI

https://www.raspberrypi.org/documentation/remote-access/ssh/passwordless.md#copy-your-public-key-to-your-raspberry-pi

10.2 Edit file

   $ sudo nano /etc/ssh/sshd_config

Uncomment PassowrdAuthentication and set it to no;

Uncomment PermitRootLogin prohibit-passowrd;

10.3 Reload SSH

   $ sudo /etc/init.d/ssh restart

10.4 Reboot RPi

   $ sudo reboot

10.5 In my computer:

   $ cd ~/.ssh

   $ sudo nano config

Add to the document:

   Host newhostname
       User name
       Hostname 192.000.0.0
       Port 22
       Identityfile /Users/ritagraca/.ssh/id_rsa
       Serveraliveinterval 30

10.6 To ssh to my pi now:

   $ ssh newhostname

DONE!!!
