Sevan Janiyan 26b5613dfc For the udp-client example, instruct user to add an entry for a udp based 
service.
For tcp-client & udp-client, use the same port in configuration snippet as used
in the comment prior to remove any ambiguity on the port number which needs to
be specified.

# 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.

# 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

# 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

# Ppp will use the FRAMED characteristics supplied by the radius server

# row fail.
#
# Make sure you don't have "deny lqr" in your default: on the client !

#
# 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.

# 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.
#

# clients on numbers configured in /etc/ppp/ppp.secret (the 5th field):
#

# 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.

# 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 lqr echo proxy # Enable LQR and proxy-arp
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.
