NAME
ppp —
point to point protocol network
interface
SYNOPSIS
options PPP_BSDCOMP
options PPP_DEFLATE
options PPP_FILTER
pseudo-device ppp
DESCRIPTION
Theppp 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.

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