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.

protocols are supported.
