ppp -- point to point protocol network interface
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).
ppp%d: af%d not supported . The interface was handed a message with
addresses formatted in an unsuitable address family; the packet was
inet(4), intro(4), sl(4), pppd(8), pppstats(8)
The Point-to-Point Protocol (PPP), RFC 1661, July 1994.
The ppp device appeared in NetBSD 1.0.
Currently, only the ip(4) and ip6(4) protocols are supported.
