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 ppp
N
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.

device appeared in

BUGS
