Complete the code to connect to a Raspberry Pi using SSH.

Raspberry Pi

ssh [1]@192.168.1.10

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'root' or 'admin' as username which are not default for Raspberry Pi.

Omitting the username before the @ symbol.

The default username for Raspberry Pi is pi. So the SSH command should use pi@192.168.1.10 to connect.

Complete the command to specify a custom SSH port 2222 when connecting.

Raspberry Pi

💡 Hint

Common Mistakes

Using the default port 22 instead of the custom port 2222.

Confusing port numbers with common web ports like 80 or 443.

The -p option in SSH specifies the port number. Here, the custom port is 2222.

💡 Hint

Common Mistakes

Omitting the '@' symbol after the username.

Placing '@' in the wrong position.

The correct syntax for SCP requires the username followed by @ before the IP address, like pi@192.168.1.10.

Fill in the blank to create a dictionary comprehension that maps hostnames to their IPs if the IP starts with '192'.

Raspberry Pi

hosts = {name: ip for name, ip in devices.items() if ip.[1]('192')}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'endswith' or 'contains' which do not check the start of the string.

Using 'equals' which requires exact match.

The startswith method checks if the IP string begins with '192'.

5fill in blank

hard

Fill all three blanks to create a dictionary comprehension that maps usernames to their home directories if the directory path contains '/home'.

Raspberry Pi

user_dirs = { [1] : [2] for [1], [2] in [3].items() if '/home' in [2] }

Drag options to blanks, or click blank then click option'

Bdirectory

Cuser_dir

Dusers

💡 Hint

Common Mistakes

Using the wrong variable names that don't match the loop variable.

Not checking the directory string correctly.

The comprehension iterates over users.items() with user and directory as key and value. The condition checks if '/home' is in the directory path.
