pppd is used in various scenarios to create a network connection according to the PPP standard between two systems over serial connections. Several configuration files can be put in /etc/ppp/peers, passwords in /etc/ppp/chap-secrets and /etc/ppp/pap-secrets, and "inet ppp" definitions in the file /etc/network/interfaces.

Contents

GPRS

See manually using GPRS.

The main scenario on OpenMoko is the cellar GPRS connection for internet access.

Bluetooth DUN

See manually using Bluetooth.

Another feature that requires PPP is accessing an OpenMoko device over Bluetooth within the DUN ("dial-up networking") profile.

Remote pppd

The GSM modem of an OpenMoko device can be made available for a computer connected via USB or Bluetooth, using a serial device, SSH, or a TCP port. In this case, pppd run on the computer can establish a GPRS connection.

QEMU

See QEMU#Simple network connection with pppd.

If instead of a real OpenMoko device QEMU is used to emulate one, it can be networked with the host computer via an emulated serial port.

VPN

Secure VPN (virtual private network) connections can be established using pppd over SSH or PPTP.
