Terminal and Login

Most of the instructions on this side assume a MacBook terminal window is being used. Using the terminal window, login to the Raspberry Pi using ssh.

• For a Windows PC, follow these directions to open a terminal window

• For a MacBook, open a terminal window from a Finder window >> Applications >> Utilities >> terminal. I keep terminal in my dock.

avahi-daemon comes installed on raspbian by default. avahi-daemon allows you login to your Raspberry Pi by hostname. I think this is easier then remembering or looking up the host's ip address.

Text enclosed within ♣s should be replaced with your value. See My Standards

Step 1. If the hostname has not been set

Open your ISP's gateway, and find your new Raspberry Pi's address, or use Angry IP Scanner and find your Raspberry Pi's IP Address.

Open a terminal window and login using one of the following:

$ ssh pi@♣ip-address♣

$ ssh pi@raspberrypi

$ ssh pi@raspberrypi.local

If ssh times out on first login, run the command again. If prompted for permission, type: yes

$ ssh pi@♣ip-address♣

ssh: connect to host raspberrypi port 22: Operation timed out

$ ssh pi@♣ip-address♣

The authenticity of host 'raspberrypi (♣ip-address♣)' can't be established.

ECDSA key fingerprint is SHA256:♣key♣

Are you sure you want to continue connecting (yes/no/[fingerprint])? yes

Step 2. Once the hostname has been set

Open a terminal window and login in to the Raspberry Pi using one of the commands:

$ ssh pi@♣hostname♣

$ ssh pi@♣hostname♣.local

default user = pi

default password = raspberry

password: ♣your-raspberry-pi-password♣

Troubleshooting:

Replace variables enclosed ♣s with your value

If ssh does not work:

If the ssh command above does not work, try:

$ ssh pi@♣hostname♣.local

If ssh gives Known Hosts message:

If you get something like:

Offending key for IP in /Users/♣macbook♣/.ssh/known_hosts:♣#♣

On the Mac, run the command

$ sudo nano /Users/♣macbook♣/.ssh/known_hosts

and type CTRL-_ (ignore the dash. underscore = CTRL, shift and minus) and enter ♣#♣

this will move the editor to the line to delete. Type CTRL-k to delete the line

CTRL-o to write the file

CTRL-x to exit the editor
