.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
interface allows serial lines to be used as network interfaces using the
|
|
.Em Point-to-Point Protocol
|
|
(PPP).
|
|
The
|
|
.Nm
|
|
interface can use various types of compression and has many features
|
|
over the SLIP protocol used by the
|
|
.Xr sl 4
|
|
interface.
|
|
.Pp
|
|
Supported options are:
|
|
.Bl -tag -width 20n -compact
|
|
.It Cd options PPP_BSDCOMP
|
|
Enable support for BSD-compress (`bsdcomp') compression in ppp.
|
|
.It Cd options PPP_DEFLATE
|
|
Enable support for deflate compression in ppp.
|
|
.It Cd options PPP_FILTER
|
|
This option turns on
|
|
.Xr pcap 3
|
|
based filtering for ppp connections.
|
|
This option is used by
|
|
.Xr pppd 8
|
|
which needs to be compiled with
|
|
.Em PPP_FILTER
|
|
defined (the current default).
|
|

.Sh DIAGNOSTICS
|
|
.Bl -diag
|
|
.It 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.
