# 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 proceedure
|
|
# 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 forth 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.

# Server side PPP
|
|
# If you want the remote system to authenticate itself, you insist
|
|
# that the peer uses CHAP (or PAP) with the "enable" keyword. Both CHAP and
|
|
# PAP are disabled by default (we usually only "enable" one of them if the
|
|
# other side is dialing into our server).
|
|
# When the peer authenticates itself, we use ppp.secret for verification.
|
|
#
|
|
# Ppp is launched with:
|
|
# # ppp -direct CHAPserver
|
|
#
|
|
# Note: We can supply a third field in ppp.secret specifying the IP address
|
|
# for that user. We can even specify a forth field to specify the
|
|
# ppp.link{up,down} label to use.
