pptp [server] --nolaunchpppd
Connect with debug output
pptp [server] debug
Connect with increased log verbosity
pptp [server] --loglevel [3]
说明
pptp establishes VPN connections using the Point-to-Point Tunneling Protocol. It creates a tunnel to a remote PPTP server by wrapping PPP sessions inside GRE (Generic Routing Encapsulation) packets. The client works in conjunction with pppd which handles the PPP negotiation and authentication within the tunnel. Any options not recognized by pptp are passed to pppd. PPTP is considered a legacy protocol with known security weaknesses, and modern alternatives like OpenVPN or WireGuard are recommended for new deployments.
