说明
pppd is the Point-to-Point Protocol daemon that establishes and manages PPP network connections over serial links, modems, and Ethernet. It handles link negotiation, authentication (PAP, CHAP, EAP), IP address assignment, and DNS configuration. The daemon is typically invoked through helper scripts like pon or pppoe-connect rather than directly. Provider configuration files in /etc/ppp/peers/ define connection parameters for different ISPs or VPN endpoints. Plugins extend functionality for PPPoE, RADIUS authentication, and other protocols.
