PPP(4) BSD Kernel Interfaces Manual PPP(4)NAMEppp — point to point protocol network interface
SYNOPSIS
options PPP_BSDCOMP
options PPP_DEFLATE
options PPP_FILTER
pseudo-device pppDESCRIPTION
The ppp interface allows serial lines to be used as network interfaces
using the Point-to-Point Protocol (PPP). The ppp interface can use vari‐
ous 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') com‐
pression 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.
