Why SSH enables secure remote management in Linux CLI - See It in Action

Why SSH Enables Secure Remote Management

📖 Scenario: You are a system administrator who needs to manage a remote Linux server safely over the internet. You want to understand why SSH (Secure Shell) is the best tool for this job.

🎯 Goal: Learn how to use SSH to connect securely to a remote server and understand the key features that make SSH secure for remote management.

📋 What You'll Learn

Create a variable with the remote server IP address

Create a variable with the SSH port number

Write the SSH command using the variables to connect to the server

Print the SSH command to show how it enables secure remote management

💡 Why This Matters

🌍 Real World

System administrators use SSH every day to securely manage servers from anywhere in the world.

💼 Career

Knowing how to use SSH is essential for IT jobs involving server management, cloud computing, and network security.

1

Set the remote server IP address

Create a variable called server_ip and set it to the string "192.168.1.100" which is the IP address of the remote server.

Linux CLI

# Create a variable called server_ip and set it to "192.168.1.100"
# Your code here

Need a hint?

Use quotes around the IP address since it is a string.

2

Set the SSH port number

Create a variable called ssh_port and set it to the number 22, which is the default SSH port.

Linux CLI

server_ip = "192.168.1.100"
# Create a variable called ssh_port and set it to 22
# Your code here

Need a hint?

Use a number without quotes for the port.

3

Write the SSH command using variables

Create a variable called ssh_command that stores the SSH command string to connect to the server using ssh, the ssh_port, and the server_ip. Use this exact format: ssh -p {ssh_port} user@{server_ip} where user is the username.

Linux CLI

server_ip = "192.168.1.100"
ssh_port = 22
# Create ssh_command using f-string: ssh -p {ssh_port} user@{server_ip}
# Your code here

Need a hint?

Use an f-string to insert variables inside the command string.

4

Print the SSH command

Write a print statement to display the ssh_command variable. This shows the exact command to securely connect to the remote server.

Linux CLI

server_ip = "192.168.1.100"
ssh_port = 22
ssh_command = f"ssh -p {ssh_port} user@{server_ip}"
# Print the ssh_command variable
# Your code here

Need a hint?

Use print(ssh_command) to show the command.
