the userland ppp(9) code goes awa. Having too much ppp choice in the 

tree results in one-true-ppp not coming into existance.  This code is
essentially un-audited and quite dangerous.

# 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 section. Blank lines and lines
# beginning with ``#'' are ignored.
#
# 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* loaded by the ``load'' or ``dial'' commands.
#
# This is the best place to specify your modem device, its DTR rate,
# and any logging specification. Logging specs should be done first
# so that subsequent commands are logged.

# Client side PPP
#
# Although the PPP protocol is a peer to peer protocol, we normally
# consider the side that makes 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:
# 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.
#
# 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 numbers.
#
# 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 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.
#
# Finally, the ``enable dns'' bit 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, /etc/resolv.conf will automatically be
# updated.

# To connect via a GPRS or UMTS device (e.g. a mobile phone or a PC Card),
# it's often necessary to set the access-point name (in this case 'internet')
# which requires quotes in the dial string. This section shows the escaping
# required. Devices that have not already authenticated the SIM card (like a
# PC Card) need to issue the "AT+CPIN=xxxx" (xxxx being the PIN for the SIM
# card) first.
# For certain devices it is necessary to adjust the baud rate (speed setting)
# and/or change the dial string to "*99***1#".
# UMTS devices often allow control of the connect mode (UMTS only, GPRS only
# or default to which is available); this can be controlled with the number
# passed to the AT+CGDCONT command and is device dependant.
# Some ISPs do special things in their IPCP session in order to negotiate
# the IP addresses; in this case it may be necessary to play with the ifaddr
# setting.

# Ppp can accept control instructions from the ``pppctl'' program.

# When the peer authenticates itself, we use ppp.secret for verification.

# It is no longer necessary to re-add the default route here as our
# ppp.conf route is `sticky' (see the man page).
# If you're into sound effects when the link comes up, you can run
# ``auplay'' (assuming NAS is installed and configured).
#
MYADDR:
!bg /usr/X11R6/bin/auplay /etc/ppp/linkup.au
# If we've got 192.244.176.32 as our address, then regard peer as a gateway
# to 192.244.176.0 network. This may also be done in ppp.conf instead.
#
192.244.176.32:
add 192.244.176.0 0 HISADDR
#You may want to execute a script after connecting. This script can do
# nice things such as kick off "sendmail -q", "popclient my.isp" and
# "slurp -d news". It can be passed MYADDR, HISADDR and INTERFACE
# as arguments too - useful for informing a DNS of your assigned IP.
#
# You may also want some sound effects....
#
pmdemand:
!bg /etc/ppp/ppp.etherup.pmdemand
! sh -c "cat /etc/ppp/linkup.au >/dev/audio"
# If your minimum call charge is 5 minutes, you may as well stay on
# the line for that amount of time. If we want a 60 second subsequent
# timeout, set your timeout to 300 in ppp.conf and then do this:
#
min5minutes:
!bg sh -c "sleep 240; pppctl -p mypassword 3000 set timeout 60"

# Example of ppp.secret file
#
# This file is used to authenticate incoming connections.
# You must ``enable'' either PAP or CHAP in your ppp.conf file.
# The peer may then use any of the Authname/Authkey pairs listed.
# Additionally, if ``passwdauth'' is enabled and an entry isn't
# found in this file, the passwd(5) database is used.
#
# If the password is specified as "*", look it up in passwd(5).
# This doesn't work for CHAP connections as ppp must have access
# to the unencrypted password for CHAP.
#
# If an IP address or address range is given as the third field, it
# will be assigned to the peer. A ``*'' or an empty field may be
# used as a placeholder if you do not wish to override the IP
# address, but wish to specify further fields.
#
# If a label is given as the forth field, it is used when reading
# the ppp.linkup and ppp.linkdown files. A ``*'' or an empty field
# can be used as a placeholder if you do not wish to override the
# label, but wish to specify further fields.
#
# If a phone number or list of phone numbers is given as the fifth
# field, these numbers will be used to call back the client if
# ``auth'' or ``cbcp'' callback is enabled (see ``set callback'').
# A ``*'' specifies that the client must specify the number.
