# 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. Ensure that the "delete"
|
|
# and "add" lines are also present in the pmdemand section of ppp.linkup
|
|
# so that when we connect, things will be put straight.
|
|
#
|
|
# This will work with static IP numbers too. You can also use this entry
|
|
# if you don't want on-demand dialup. The "set ifaddr", "delete" and
|
|
# "add" lines are required for on-demand. Note, for dynamic IP numbers,
|
|
# whether dialing manually or on demand, there should *always* be an entry
|
|
# in ppp.linkup.
|
|
#
|
|
# 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.

# When in -auto, -ddial, -direct or -background mode, ppp can accept

# control instructions from the ``pppctl'' program. First, you must

|
|
set server /var/tmp/internet 0177

# 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" on 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.
