PPP(4) BSD 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
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.

The Point-to-Point Protocol (PPP), RFC 1661, July 1994.
HISTORY
The ppp device appeared in NetBSD 1.0.
BUGS
Currently, only the ip(4) and ip6(4) protocols are supported.

PON(1) Debian PPPD PON(1)NAME
pon, poff, plog - starts up, shuts down or lists the log of PPP connections
SYNOPSIS
pon [ isp-name [ options ] ]
poff [ -r ] [ -d ] [ -c ] [ -a ] [ -h ] [ isp-name ]
plog [ arguments ]
DESCRIPTION
This manual page describes the pon, plog and poff scripts, which allow users to control PPP connections.
pon
pon, invoked without arguments, runs the /etc/ppp/ppp_on_boot file, if it exists and is executable. Otherwise, a PPP connection will be
started using configuration from /etc/ppp/peers/provider. This is the default behaviour unless an isp-name argument is given.
For instance, to use ISP configuration "myisp" run:
pon myisp
pon will then use the options file /etc/ppp/peers/myisp. You can pass additional pppd options after the ISP name, too. pon can be used to
run multiple, simultaneous PPP connections.
pon takes the following command line options:
-q --quick
disconnect when ip-up finishes running. This function is only available to the root user.
poff
poff closes a PPP connection. If more than one PPP connection exists, the one named in the argument to poff will be killed, e.g.
poff myprovider2
will terminate the connection to myprovider2, and leave the PPP connections to e.g. "myprovider1" or "myprovider3" up and running.
poff takes the following command line options:
-r causes the connection to be redialed after it is dropped.
-d toggles the state of pppd's debug option.
-c causes pppd(8) to renegotiate compression.
-a stops all running ppp connections. If the argument isp-name is given it will be ignored.
-h displays help information.
-v prints the version and exits.
If no argument is given, poff will stop or signal pppd if and only if there is exactly one running. If more than one connection is
active, it will exit with an error code of 1.
plog
plog shows you the last few lines of /var/log/ppp.log. If that file doesn't exist, it shows you the last few lines of your /var/log/syslog
file, but excluding the lines not generated by pppd. This script makes use of the tail(1) command, so arguments that can be passed to
tail(1) can also be passed to plog.
Note: the plog script can only be used by root or another system administrator in group "adm", due to security reasons. Also, to have all
pppd-generated information in one logfile, that plog can show, you need the following line in your /etc/syslog.conf file:
local2.* -/var/log/ppp.log
FILES
/etc/ppp/options
PPPd system options file.
/etc/ppp/pap-secrets
System PAP passwords file.
/etc/ppp/chap-secrets
System CHAP passwords file.
/etc/ppp/peers/
Directory holding the peer options files. The default file is called provider.
/etc/chatscripts/provider
The chat script invoked from the default /etc/ppp/peers/provider.
/var/log/ppp.log
The default PPP log file.
