In Linux systems, including Debian 12, the sudo group grants users the ability to execute administrative commands. This provides them with the privileges to install, update, and delete software, modify system configurations, and more.
The sudo command is a very important command on Linux systems. You might say that it allows users to run privileged commands without logging in as root, and that is true.
Here's how you can install Elasticsearch, a powerful search and analytics engine on your Ubuntu machine.
In Debian, managing user privileges and administrative access is crucial for maintaining a secure and efficient system. By granting users the ability to execute administrative tasks without relying on the root account, you can enhance security, control access to sensitive operations, and maintain an audit trail of user activity.
In the client-server architecture used by the SSH protocol, a client can authenticate by providing a tunneled clear text password or by using a public/private key pair: this is called public key authentication. A user who logs in via a public key on a remote machine has complete access to the command line; in certain situations, however, it may be useful to associate a public key to a single specific command, for security reasons.
