How to use the command pppd (with examples)

The pppd command is used to establish a Point-to-Point connection to another computer. It is a daemon that is typically started automatically when needed, rather than invoked manually. This command is commonly used for setting up PPP (Point-to-Point Protocol) connections, which allow communication between two computers over a serial interface or other network medium.

Use case 1: Start the daemon

Code:

pppd

Motivation: The motivation for starting the pppd daemon is to allow the establishment of Point-to-Point connections when required. By starting the daemon, the computer can be ready to establish a PPP connection with another device or computer.

Explanation: When the pppd command is used without any arguments, it starts the pppd daemon. The daemon runs in the background and waits for a connection request or other events after being started.

Example output:

pppd[1234]: pppd started

In this example, the pppd daemon is started, and it prints a message indicating that it has been started successfully.

Conclusion:

The pppd command is a powerful tool for establishing Point-to-Point connections using PPP. By understanding the various use cases of this command and how to use it, you can effectively establish connections with other devices or computers. It is important to refer to the official documentation for more information and specific use cases.
