PPP(4)

NAME
ppp - Point-to-Point Protocol network interface

SYNOPSIS
pseudo-device ppp

DESCRIPTION
The ppp interface allows serial lines to be used as network interfaces using the Point-to-Point Protocol (PPP).

A ppp interface can be created at runtime using the ifconfig pppN create command or by setting up a hostname.if(5) configuration file for netstart(8).

The ppp interface can use various types of compression and has many advantages over the SLIP protocol used by the sl(4) interface.

DIAGNOSTICS

ppp0: afX not supported The interface was handed a message with addresses formatted in an unsuitable address family; the packet was dropped.

BUGS
