Streamlining SSH Key Management

Managing SSH authentication keys for multiple servers is challenging and risky.
A Bash script can be used to streamline, secure, and manage the SSH key pairs.
The SSH config file ( .ssh/config ) contains key parameters to manage various SSH connections.
The config file can be organized and simplified by using include files.
The Bash script generates unique key pairs, creates a config file for each server, and ensures they link back to the main config file.
The script creates a directory to store the SSH key pair and configuration file, sets file permissions, and generates SSH key pairs using ed25519 algorithm, with no passphrase.
A config file for the new login is created and stored in the same directory as the SSH keys.
Linking the server’s address and username into a single alias simplifies connecting to servers.
The script also tests the login and logs out the remote server at the end of the script.
The script enhances SSH key security while making it easier to generate keys and keep them well-organized.

How to create a sudo user

Root user in Linux has the highest privileges but it's discouraged to be used regularly to prevent security issues. A sudo command allows a regular user to execute administrative tasks. A sudo user is a normal user that can execute a sudo command by adding a normal user to the sudo system group.
To create a sudo user, a Linux server with root access is required. Firstly, a new user needs to be added using the 'adduser' command followed by prompts to assign a password and other optional information. Once the user is added, it's privileges then need to be elevated to superuser using the 'usermod' command where the new user account is added to the sudo system group.
To verify the sudo user, switch to the newly created user and try to run administrative tasks using the 'sudo' command followed by the task.
FreeBSD requires the sudo package to be installed before its usage.
To create a sudo user on FreeBSD, you need to install sudo using ports or pkg, and then create the user account followed by assigning the wheel group to the newly created user. Finally, the sudoers file needs to be edited to include the wheel group to allow them to run all commands.
When editing sudoers file, visudo should be used instead of editing it directly because it checks for errors before saving any changes.
Rocky Linux steps not included because they are not available at the time of writing.
