NAME
pppd - Point to Point Protocol daemon
SYNOPSIS
pppd [ tty_name ] [ speed ] [ options ]
DESCRIPTION
The Point-to-Point Protocol (PPP) provides a method for
transmitting datagrams over serial point-to-point links.
PPP is composed of three parts: a method for encapsulating
datagrams over serial links, an extensible Link Control
Protocol (LCP), and a family of Network Control Protocols
(NCP) for establishing and configuring different network-
layer protocols.
The encapsulation scheme is provided by driver code in the
kernel. Pppd provides the basic LCP, authentication sup-
port, and an NCP for establishing and configuring the
Internet Protocol (IP) (called the IP Control Protocol,
IPCP).
FREQUENTLY USED OPTIONS
Communicate over the named device. The string
"/dev/" is prepended if necessary. If no device
name is given, or if the name of the terminal con-
nected to the standard input is given, pppd will
use that terminal, and will not fork to put itself
in the background. A value for this option from a
privileged source cannot be overridden by a non-
privileged user.
Set the baud rate to (a decimal number).
On systems such as 4.4BSD and NetBSD, any speed can
be specified. Other systems (e.g. SunOS) allow
only a limited set of speeds.
