PPP(4)                  NetBSD Kernel Interfaces Manual                 PPP(4)


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 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.

BUGS

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