 11# This file is separated into sections.  Each section is named with
 12# a label starting in column 0 and followed directly by a ``:''.  The
 13# section continues until the next label.  Blank lines and characters
 14# after a ``#'' are ignored (a literal ``#'' must be escaped with a ``\''
 15# or quoted with "").  All commands inside sections that do not begin
 16# with ``!'' (e.g., ``!include'') *must* be indented by at least one
 17# space or tab or they will not be recognized!
 18#
 19# Lines beginning with "!include" will ``include'' another file.  You
 20# may want to ``!include ~/.ppp.conf'' for backwards compatibility.

 26#  This is the best place to specify your modem device, its DTR rate,
 27#  your dial script and any logging specification.  Logging specs should
 28#  be done first so that the results of subsequent commands are logged.

 37# Client side PPP
 38#
 39#  Although the PPP protocol is a peer to peer protocol, we normally
 40#  consider the side that initiates the connection as the client and
 41#  the side that receives the connection as the server.  Authentication
 42#  is required by the server either using a unix-style login procedure
 43#  or by demanding PAP or CHAP authentication from the client.
 44#
 45
 46# An on demand example where we have dynamic IP addresses and wish to
 47# use a unix-style login script:
 48#
 49#  If the peer assigns us an arbitrary IP (most ISPs do this) and we
 50#  can't predict what their IP will be either, take a wild guess at
 51#  some IPs that you can't currently route to.  Ppp can change this
 52#  when the link comes up.
 53#
 54#  The /0 bit in "set ifaddr" says that we insist on 0 bits of the
 55#  specified IP actually being correct, therefore, the other side can assign
 56#  any IP number.
 57#
 58#  The fourth arg to "set ifaddr" makes us send "0.0.0.0" as our requested
 59#  IP number, forcing the peer to make the decision.  This is necessary
 60#  when negotiating with some (broken) ppp implementations.
 61#
 62#  This entry also works with static IP numbers or when not in -auto mode.
 63#  The ``add'' line adds a `sticky' default route that will be updated if
 64#  and when any of the IP numbers are changed in IPCP negotiations.
 65#  The "set ifaddr" is required in -auto mode only.
 66#  It's better to put the ``add'' line in ppp.linkup when not in -auto mode.
 67#
 68#  Finally, the ``enable dns'' line tells ppp to ask the peer for the
 69#  nameserver addresses that should be used.  This isn't always supported
 70#  by the other side, but if it is, ppp will update /etc/resolv.conf with
 71#  the correct nameserver values at connection time.
 72#
 73#  The login script shown says that you're expecting ``ogin:''.  If you
 74#  don't receive that, send a ``\n'' and expect ``ogin:'' again.  When
 75#  it's received, send ``ppp'', expect ``word:'' then send ``ppp''.
 76#  You *MUST* customise this login script according to your local
 77#  requirements.

 87# If you want to use PAP or CHAP instead of using a unix-style login

106#
107#  # ppp -auto ondemand
108#
109#  With static IP numbers, our setup is similar to dynamic:
110#  Remember, ppp.linkup is searched for a "192.244.176.44" label, then
111#  an "ondemand" label, and finally the "MYADDR" label.

181# Ppp can accept control instructions from the ``pppctl'' program.
182# First, you must set up your control socket.  It's safest to use
183# a UNIX domain socket, and watch the permissions:
184#
185    set server /var/run/ppp/internet MySecretPassword 0177
186#
187# Although a TCP port may be used if you want to allow control
188# connections from other machines:
189#
190    set server 6670 MySecretpassword
191#
192# If you don't like ppp's builtin chat, use an external one:
193#
194    set login "\"!chat \\-f /etc/ppp/ppp.dev.chat\""
195#
196# If we have a ``strange'' modem that must be re-initialized when we
197# hangup:
198#
199    set hangup "\"\" AT OK-AT-OK ATZ OK"
200#
201# To adjust logging without blowing away the setting in default:
202#
203    set log -command +tcp/ip
204#
205# To see log messages on the screen in interactive mode:
206#
207    set log local LCP IPCP CCP

212    set openmode active 5
213#
214# For noisy lines, we may want to reconnect (up to 20 times) after loss

223#
224# Inform the client if they ask for our DNS IP numbers:
225#
226    enable dns
227#
228# If you don't want to tell them what's in your /etc/resolv.conf file

408#
409#  If you want the remote system to authenticate itself, you must insist
410#  that the peer uses CHAP or PAP with the "enable" keyword.  Both CHAP and
411#  PAP are disabled by default.  You may enable either or both.  If both
412#  are enabled, CHAP is requested first.  If the client doesn't agree, PAP
413#  will then be requested.
414#
415#  Note:  If you use the getty/login process to authenticate users, you
416#         don't need to enable CHAP or PAP, but the user that has logged
417#         in *MUST* be a member of the ``network'' group (in /etc/group).
418#
419#  Note:  Chap80 and chap81 are Microsoft variations of standard chap (05).
420#
421#  If you wish to allow any user in the passwd database ppp access, you
422#  can ``enable passwdauth'', but this will only work with PAP.
423#
424#  When the peer authenticates itself, we use ppp.secret for verification
425#  (although refer to the ``set radius'' command below for an alternative).
426#
427#  Note:  We may supply a third field in ppp.secret specifying the IP
428#         address for that user, a fourth field to specify the
429#         ppp.link{up,down} label to use and a fifth field to specify
430#         callback characteristics.
431#
432#  The easiest way to allow transparent LAN access to your dialin users
433#  is to assign them a number from your local LAN and tell ppp to make a
434#  ``proxy'' arp entry for them.  In this example, we have a local LAN
435#  with IP numbers 10.0.0.1 - 10.0.0.99, and we assign numbers to our
436#  ppp clients between 10.0.0.100 and 10.0.0.199.  It is possible to
437#  override the dynamic IP number with a static IP number specified in
438#  ppp.secret.
439#
440#  Ppp is launched with:
441#   # ppp -direct server
442#
443server:
444 enable chap chap80 chap81 pap passwdauth
445 enable proxy

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

462# Example to connect using a null-modem cable:
463#  The important thing here is to allow the lqr packets on both sides.
464#  Without them enabled, we can't tell if the line's dropped - there
465#  should always be carrier on a direct connection.
466#  Here, the server sends lqr's every 10 seconds and quits if five in a
467#  row fail.
468#
469#  Make sure you don't have "deny lqr" in your default: on the client !
470#  If the peer denies LQR, we still send ECHO LQR packets at the given
471#  lqrperiod interval (ppp-style-pings).

611#  If you wish to connect to a server that will dial back *without* using
612#  the ppp callback facility (rfc1570), take advantage of the fact that
613#  ppp doesn't look for carrier 'till `set login' is complete:
614#
615#  Here, we expect the server to say DIALBACK then disconnect after
616#  we've authenticated ourselves.  When this has happened, we wait
617#  60 seconds for a RING.
618#
619#  Note, it's important that we tell ppp not to expect carrier, otherwise
620#  we'll drop out at the ``NO CARRIER'' stage.
621#
622dialback:
623 set dial "ABORT BUSY ABORT NO\\sCARRIER TIMEOUT 5 \"\" ATZ OK-ATZ-OK \

628
629# Example of PPP callback.
630#  Alternatively, if the peer is using the PPP callback protocol, we're
631#  happy either with ``auth'' style callback where the server dials us
632#  back based on what we authenticate ourselves with, ``cbcp'' style
633#  callback (invented by Microsoft but not agreed by the IETF) where
634#  we negotiate callback *after* authentication or E.164 callback where
635#  we specify only a phone number.  I would recommend only ``auth'' and/or
636#  ``cbcp'' callback methods.
637#  For ``cbcp'', we insist that we choose ``1234567'' as the number that
638#  the server must call back.
639#
640callback:
641 load pmdemand                                    # load in the pmdemand config

665# Multilink mode is available (rfc1990).
666#  To enable multi-link capabilities, you must specify a MRRU.  1500 is
667#  a reasonable value.  To create new links, use the ``clone'' command
668#  to duplicate an existing link.  If you already have more than one
