SSH (Secure Shell) and Telnet are both protocols used to access computers and networks remotely. Although they each perform the same task, they differ in many ways.
SSH is a secure protocol, while Telnet is not. SSH uses public–key cryptography and strong authentication mechanisms to ensure that only authorized users can access a remote machine. In contrast, Telnet transfers data in plain text, which makes it extremely vulnerable to packet sniffing and man–in–the–middle attacks. In addition, SSH is more versatile than Telnet, as it allows users to tunnel traffic and create encrypted connections.
Telnet does not offer these features, so users cannot securely access a remote server without using another protocol.

Using the Rpm command in Linux is a simple process. It can be used to install, list, query, verify, upgrade, and remove individual software packages or groups of packages.
1. Listing installed packages –
To list out all of the currently installed packages on your system, you can use the option ‘–qa’ with the rpm command. This will print out a list of all currently installed packages and their details (e.g. package name, version number, etc.). Command:
$ rpm –qa
2. Installing packages –
To install packages with the rpm command, you need to specify the package name as well as the path to the RPM file. The syntax for this is: Command:
$ rpm –i <package_name> <path_to_rpm_file>
3. Querying installed packages
– If you need to find out the details of an installed package, you can do this with the ‘–q’ option. This will print out specific information such as the version number, package description, etc. Command:
$ rpm –q <package_name>
4. Verifying installed packages
– You can also use the rpm command to verify that a package is properly installed on your system. This can be done using the ‘–V’ option which will check the integrity of the installed package and will report any inconsistencies. Command:
$ rpm –V <package_name>
5. Upgrading packages
– With the ‘–U’ or ‘–F’ options, you can successfully upgrade packages to the latest version available. The difference between these two options is that the ‘–U’ will upgrade an existing package to the newest version, while the ‘–F’ option will actually replace the existing package with the new version. Command:
$ rpm –U <package_name> $ rpm –F <package_name>
6. Removing packages
– To remove an installed package, you can use the ‘–e’ option with the rpm command. This will completely remove the package from your system. Command:
$ rpm –e <package_name>
