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
 The ppp device appeared in NetBSD 1.0.
BUGS
 Currently, only the 
ip(4) and 
ip6(4) protocols are supported.
