PPP(4)

NAME
ppp - point to point protocol network interface

SYNOPSIS
options PPP_BSDCOMP
options PPP_DEFLATE
options PPP_FILTER

pseudo-device ppp

DESCRIPTION
The ppp interface allows serial lines to be used as network interfaces using the Point-to-Point Protocol (PPP). The ppp interface can use various types of compression and has many features over the SLIP protocol used by the sl(4) interface.

Supported options are:
options PPP_BSDCOMP
    Enable support for BSD-compress (`bsdcomp') compression in ppp.
options PPP_DEFLATE
    Enable support for deflate compression in ppp.
options PPP_FILTER
    This option turns on pcap(3) based filtering for ppp connections. This option is used by pppd(8) which needs to be compiled with PPP_FILTER defined (the current default).

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.

HISTORY

BUGS
Currently, only the ip(4) and ip6(4) protocols are supported.
