PPP(4) OpenBSD Programmer's Manual 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
ppp%d: af%d not supported The interface was handed a message with
addresses formatted in an unsuitable address family; the packet was
dropped.
