26*7c478bd9Sstevel@tonic-gate# Secrets for authentication using CHAP (Challenge Handshake Authentication
27*7c478bd9Sstevel@tonic-gate# Protocol) are placed here.  Each line is a separate entry and consists of
28*7c478bd9Sstevel@tonic-gate# a list of space or tab separated tokens.
29*7c478bd9Sstevel@tonic-gate#
30*7c478bd9Sstevel@tonic-gate#	client	server	secret	[IP addresses ["--" options]]
31*7c478bd9Sstevel@tonic-gate#
32*7c478bd9Sstevel@tonic-gate# When authenticating to a peer (so-called "client mode;" as when dialing
33*7c478bd9Sstevel@tonic-gate# out to an ISP), the "client" will be matched using the local name and
34*7c478bd9Sstevel@tonic-gate# "server" will use the remote peer's name.  CHAP does specify an
35*7c478bd9Sstevel@tonic-gate# authenticator name, but some peers (such as Windows NT) do not provide
36*7c478bd9Sstevel@tonic-gate# a peer name, and the "remotename <name>" option should then be used.
37*7c478bd9Sstevel@tonic-gate# Typically, the "user <name>" option is also to specify the local name.
38*7c478bd9Sstevel@tonic-gate#
39*7c478bd9Sstevel@tonic-gate# When authenticating a peer (so-called "server mode;" as when allowing
40*7c478bd9Sstevel@tonic-gate# dial-up access to this system), the remote peer's name is the "client"
41*7c478bd9Sstevel@tonic-gate# and the local system name is the "server."  In this case, the privileged
42*7c478bd9Sstevel@tonic-gate# "name <name>" option is sometimes used to set the local name.  The "user
43*7c478bd9Sstevel@tonic-gate# <name>" option cannot be used.  The remote peer's name comes from the
44*7c478bd9Sstevel@tonic-gate# CHAP messages the peer sends.
45*7c478bd9Sstevel@tonic-gate#
46*7c478bd9Sstevel@tonic-gate# After the secret, which must always be clear text for CHAP, a list of
47*7c478bd9Sstevel@tonic-gate# valid IP addresses for the peer appears.  This must be present when
48*7c478bd9Sstevel@tonic-gate# acting as a server.  Usually, this is specified as "*" and actual IP
49*7c478bd9Sstevel@tonic-gate# addresses are given in the options.  If a given dial-in peer has an
50*7c478bd9Sstevel@tonic-gate# allocated IP address ("static IP addressing"), then this address may
51*7c478bd9Sstevel@tonic-gate# be given here.  If there's exactly one address, then this will be sent
52*7c478bd9Sstevel@tonic-gate# to the peer as a hint.
53*7c478bd9Sstevel@tonic-gate#
54*7c478bd9Sstevel@tonic-gate# The entry may also have extra options after a -- token.  These are
55*7c478bd9Sstevel@tonic-gate# interpreted as privileged pppd options, and may be used to enable
56*7c478bd9Sstevel@tonic-gate# proxyarp or other optional features.
