# This file is separated into sections.  Each section is named with
# a label starting in column 0 and followed directly by a ``:''.  The
# section continues until the next label.  Blank lines and characters
# after a ``#'' are ignored (a literal ``#'' must be escaped with a ``\''
# or quoted with "").  All commands inside sections that do not begin
# with ``!'' (e.g., ``!include'') *must* be indented by at least one
# space or tab or they will not be recognized!
#
# Lines beginning with "!include" will ``include'' another file.  You
# may want to ``!include ~/.ppp.conf'' for backwards compatibility.
#

# Default setup. Always executed when PPP is invoked.
#  This section is *not* pre-loaded by the ``load'' or ``dial'' commands.
#
#  This is the best place to specify your modem device, its DTR rate,
#  your dial script and any logging specification.  Logging specs should
#  be done first so that the results of subsequent commands are logged.

# Client side PPP
#
#  Although the PPP protocol is a peer to peer protocol, we normally
#  consider the side that initiates the connection as the client and
#  the side that receives the connection as the server.  Authentication
#  is required by the server either using a unix-style login procedure
#  or by demanding PAP or CHAP authentication from the client.
#

# An on demand example where we have dynamic IP addresses and wish to
# use a unix-style login script:
#
#  If the peer assigns us an arbitrary IP (most ISPs do this) and we
#  can't predict what their IP will be either, take a wild guess at
#  some IPs that you can't currently route to.  Ppp can change this
#  when the link comes up.
#
#  The /0 bit in "set ifaddr" says that we insist on 0 bits of the
#  specified IP actually being correct, therefore, the other side can assign
#  any IP number.
#
#  The fourth arg to "set ifaddr" makes us send "0.0.0.0" as our requested
#  IP number, forcing the peer to make the decision.  This is necessary
#  when negotiating with some (broken) ppp implementations.
#
#  This entry also works with static IP numbers or when not in -auto mode.
#  The ``add'' line adds a `sticky' default route that will be updated if
#  and when any of the IP numbers are changed in IPCP negotiations.
#  The "set ifaddr" is required in -auto mode only.
#  It's better to put the ``add'' line in ppp.linkup when not in -auto mode.
#
#  Finally, the ``enable dns'' line tells ppp to ask the peer for the
#  nameserver addresses that should be used.  This isn't always supported
#  by the other side, but if it is, ppp will update /etc/resolv.conf with
#  the correct nameserver values at connection time.
#
#  The login script shown says that you're expecting ``ogin:''.  If you
#  don't receive that, send a ``\n'' and expect ``ogin:'' again.  When
#  it's received, send ``ppp'', expect ``word:'' then send ``ppp''.
#  You *MUST* customise this login script according to your local
#  requirements.

#  # ppp -auto ondemand
#
#  With static IP numbers, our setup is similar to dynamic:

# Server side PPP
#
#  If you want the remote system to authenticate itself, you must insist
#  that the peer uses CHAP or PAP with the "enable" keyword.  Both CHAP and
#  PAP are disabled by default.  You may enable either or both.  If both
#  are enabled, CHAP is requested first.  If the client doesn't agree, PAP
#  will then be requested.
#
#  Note:  If you use the getty/login process to authenticate users, you
#         don't need to enable CHAP or PAP, but the user that has logged
#         in *MUST* be a member of the ``network'' group (in /etc/group).
#
#  Note:  Chap80 and chap81 are Microsoft variations of standard chap (05).
#
#  If you wish to allow any user in the passwd database ppp access, you
#  can ``enable passwdauth'', but this will only work with PAP.
#
#  When the peer authenticates itself, we use ppp.secret for verification
#  (although refer to the ``set radius'' command below for an alternative).
#
#  Note:  We may supply a third field in ppp.secret specifying the IP
#         address for that user, a fourth field to specify the
#         ppp.link{up,down} label to use and a fifth field to specify
#         callback characteristics.
#
#  The easiest way to allow transparent LAN access to your dialin users
#  is to assign them a number from your local LAN and tell ppp to make a
#  ``proxy'' arp entry for them.  In this example, we have a local LAN
#  with IP numbers 10.0.0.1 - 10.0.0.99, and we assign numbers to our
#  ppp clients between 10.0.0.100 and 10.0.0.199.  It is possible to
#  override the dynamic IP number with a static IP number specified in
#  ppp.secret.
#
#  Ppp is launched with:
#   # ppp -direct server
#
server:
 enable chap chap80 chap81 pap passwdauth
 enable proxy
 set ifaddr 10.0.0.1 10.0.0.100-10.0.0.199

# Example of a RADIUS configuration:
#  If there are one or more radius servers available, we can use them
#  instead of the ppp.secret file.  Simply put then in a radius
#  configuration file (usually /etc/radius.conf) and give ppp the
#  file name.
#  Ppp will use the FRAMED characteristics supplied by the radius server
#  to configure the link.

radius-server:
 load server                    # load in the server config from above
 set radius /etc/radius.conf


# Example to connect using a null-modem cable:
#  The important thing here is to allow the lqr packets on both sides.
#  Without them enabled, we can't tell if the line's dropped - there
#  should always be carrier on a direct connection.
#  Here, the server sends lqr's every 10 seconds and quits if five in a
#  row fail.
#
#  Make sure you don't have "deny lqr" in your default: on the client !
#  If the peer denies LQR, we still send ECHO LQR packets at the given
#  lqrperiod interval (ppp-style-pings).

#
#    ppp stream tcp nowait root /usr/sbin/ppp ppp -direct tcp-server
#
#  with this in /etc/services:
#
#    ppp 6671/tcp
#
#  Read the man page for further details.
#
#  Note, we assume we're using a binary-clean connection.  If something
#  such as `rlogin' is involved, you may need to ``set escape 0xff''

# Example of a VPN.
#  If you're going to create a tunnel through a public network, your VPN

 # Passive mode allows ssh plenty of time to establish the connection
 set openmode passive
 set device "!ssh whatevermachine /usr/sbin/ppp -direct inet-loop-in"

# Example of non-PPP callback.
#  If you wish to connect to a server that will dial back *without* using
#  the ppp callback facility (rfc1570), take advantage of the fact that
#  ppp doesn't look for carrier 'till `set login' is complete:
#
#  Here, we expect the server to say DIALBACK then disconnect after
#  we've authenticated ourselves.  When this has happened, we wait
#  60 seconds for a RING.
#
#  Note, it's important that we tell ppp not to expect carrier, otherwise
#  we'll drop out at the ``NO CARRIER'' stage.
#
dialback:
 set dial "ABORT BUSY ABORT NO\\sCARRIER TIMEOUT 5 \"\" ATZ OK-ATZ-OK \
           ATDT\\T TIMEOUT 60 CONNECT"
 set cd off
 set login "TIMEOUT 5 ogin:--ogin: ppp word: ppp TIMEOUT 15 DIALBACK \
           \"\" NO\\sCARRIER \"\" TIMEOUT 60 RING ATA CONNECT"

# Example of PPP callback.
#  Alternatively, if the peer is using the PPP callback protocol, we're
#  happy either with ``auth'' style callback where the server dials us
#  back based on what we authenticate ourselves with, ``cbcp'' style
#  callback (invented by Microsoft but not agreed by the IETF) where
#  we negotiate callback *after* authentication or E.164 callback where
#  we specify only a phone number.  I would recommend only ``auth'' and/or
#  ``cbcp'' callback methods.
#  For ``cbcp'', we insist that we choose ``1234567'' as the number that
#  the server must call back.
#
callback:
 load pmdemand                                    # load in the pmdemand config
 set callback auth cbcp e.164 1234567
 set cbcp 1234567

# If we're running a ppp server that wants to only call back microsoft
# clients on numbers configured in /etc/ppp/ppp.secret (the 5th field):
#
callback-server:
 load server
 set callback cbcp
 set cbcp
 set log +cbcp
 set redial 3 1
 set device /dev/cuad0
 set speed 115200
 set dial "TIMEOUT 10 \"\" AT OK-AT-OK ATDT\\T CONNECT"

# Or if we want to allow authenticated clients to specify their own
# callback number:
#
callback-server-client-decides:
 load callback-server
 set cbcp *

# Multilink mode is available (rfc1990).
#  To enable multi-link capabilities, you must specify a MRRU.  1500 is
#  a reasonable value.  To create new links, use the ``clone'' command
#  to duplicate an existing link.  If you already have more than one
#  link, you must specify which link you wish to run the command on via
#  the ``link'' command.
#
#  It's worth increasing your MTU and MRU slightly in multi-link mode to
#  prevent full packets from being fragmented.
#
#  You can now ``dial'' specific links, or even dial all links at the
#  same time.  The `dial' command may also be prefixed with a specific
#  link that should do the dialing.

# User supplied authentication:
#  It's possible to run ppp in the background while specifying a
#  program to use to obtain authentication details on demand.
#  This program would usually be a simple GUI that presents a
#  prompt to a known user.  The ``chap-auth'' program is supplied
#  as an example (and requires tcl version 8.0).
#
CHAPprompt:
 load PAPorCHAPpmdemand
 set authkey !/usr/share/examples/ppp/chap-auth

#  It's possible to do the same sort of thing at the login prompt.
#  Here, after sending ``brian'' in response to the ``name'' prompt,
#  we're prompted with ``code:''.  A window is then displayed on the
#  ``keep:0.0'' display and the typed response is sent to the peer
#  as the password.  We then expect to see ``MTU'' and ``.'' in the
#  servers response.
#
loginprompt:
 load pmdemand
 set authname "brian"
 set login "ABORT NO\\sCARRIER TIMEOUT 15 \"\" \"\" name:--name: \\U \
            code: \"!/usr/share/examples/ppp/login-auth -display keep:0.0 \

# ppp supports ppp over ethernet (PPPoE).  Beware, many PPP servers cache
# the MAC address that connects to them, making it impossible to switch
# your PPPoE connection between machines.
#
# The current implementation requires Netgraph, so it doesn't work with
# OpenBSD or NetBSD.
#
# The client should be something like this:
#
pppoe:
 set device PPPoE:de0:pppoe-in
 enable lqr echo
 set cd 5
 set dial
 set login
 set redial 0 0

# And the server should be running
#
#   /usr/libexec/pppoed -p pppoe-in fxp0
#
# See rc.conf(5)
#
pppoe-in:
 allow mode direct                              # Only for use on server-side

 enable chap pap passwdauth                     # Force client authentication
 set ifaddr 10.0.0.1 10.0.0.100-10.0.0.199      # Hand out up to 100 IP numbers
 accept dns                                     # Allow DNS negotiation

# It's possible to run ppp back-to-back with itself.  This is useful
# for testing.
#
# When testing scalability and concurrency, the following profile might
# be used.
#
# Note, you'll have to make some other machine adjustments:
#
#  o Bump maxusers in your kernel configuration to about 256 so that there
#    are enough process table slots.
#  o Bump system file descriptors with ``sysctl kern.maxfiles=20480''.  You'll
#    need 3 descriptors per ppp process (assuming no server socket).
#
# You can now create 2000 processes (1000 pairs) with:
#
#    n=0
#    while [ $n -lt 1000 ]; do ppp -b loop; n=$(($n + 1)); done
#
# If you want to test concurrency, try using ``ppp -dd loop'' instead.
