How To Set Up SSH Keys on Ubuntu 16.04

If you're working with a remote server or need to securely transfer files between computers, using SSH keys is a good solution. This tutorial will guide you through the process of setting up SSH keys on Ubuntu 16.04.

Step 1: Check for Existing SSH Keys

First, check if you already have an SSH key on your Ubuntu system by running the following command in your terminal:

ls ~/.ssh/

Step 2: Create a New SSH Key

If you don't have an SSH key, you can generate one by running the following command:

ssh-keygen -t rsa -b 4096 -C "your_email@example.com"

Follow the prompts to create a new key.

Step 3: Add Your SSH Key to the Server

Next, you'll need to add your SSH key to the server you want to connect to. To do this, you'll need to copy your public key to the server by running the following command:

ssh-copy-id username@remote_host

Replace username with your username on the remote server and remote_host with the hostname or IP address of the remote server.

Step 4: Test Your SSH Connection

Finally, test your SSH connection by running the following command:

ssh username@remote_host

You should be prompted for your SSH key passphrase (if you set one) and then logged in to the remote server.

That's it! You've successfully set up SSH keys on Ubuntu 16.04. This will allow you to securely connect to remote servers and transfer files.
