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. 21# 22 23# Default setup. Always executed when PPP is invoked. 24# This section is *not* pre-loaded by the ``load'' or ``dial'' commands. 25# 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. 29# 30default: 31 set log Phase Chat LCP IPCP CCP tun command 32 set device /dev/cuau1 33 set speed 115200 34 set dial "ABORT BUSY ABORT NO\\sCARRIER TIMEOUT 5 \"\" AT \ 35 OK-AT-OK ATE1Q0 OK \\dATDT\\T TIMEOUT 40 CONNECT" 36 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. 78# 79pmdemand: 80 set phone 1234567 81 set login "ABORT NO\\sCARRIER TIMEOUT 5 ogin:--ogin: ppp word: ppp" 82 set timeout 120 83 set ifaddr 10.0.0.1/0 10.0.0.2/0 255.255.255.0 0.0.0.0 84 add default HISADDR 85 enable dns 86 87# If you want to use PAP or CHAP instead of using a unix-style login 88# procedure, do the following.
