The command pppd
stands for "Point-to-Point Protocol Daemon". It is a program used in Unix-like operating systems to establish a PPP (Point-to-Point Protocol) connection with a remote network or device.
The pppd
command is typically used in a terminal or command prompt, and it requires root/administrator privileges to run.
When executed, the pppd
command launches the PPP daemon that handles the PPP connection establishment and negotiation process. It initializes and configures the network interfaces, negotiates the connection parameters (such as IP addresses, authentication, compression, etc.), and manages the data transfer over the PPP connection.
The pppd
command usually requires additional options and parameters to be specified, depending on the desired configuration of the PPP connection. These options can include information about the authentication method, IP addressing, DNS settings, compression, logging, debugging, and more.
Overall, the pppd
command is a crucial tool for establishing PPP connections in Unix-like systems, allowing users to connect to remote networks, such as the internet, over various communication mediums like dial-up, DSL, satellite, or cellular connections.
