NAME

       ifcfg-ppp0 - Configuration file used by adsl-start(8), adsl-stop(8), adsl-status(8) and adsl-connect(8).

DESCRIPTION

       /etc/sysconfig/network-scripts/ifcfg-ppp0  is  a  shell script which contains configuration information for Roaring Penguin's ADSL scripts.
       Note that pppoe.conf is used only by the various adsl-* shell scripts, not by pppoe itself.

       ifcfg-ppp0 consists of a sequence of shell variable assignments.  The variables and their meanings are:

       ETH    The Ethernet interface connected to the ADSL modem (for example, eth0).

       USER   The ADSL user-id (for example, b1xxnxnx@sympatico.ca).

       SERVICENAME
	      If this is not blank, then it is passed with the -S option to pppoe.  It specifies a service name to ask for.  Usually,  you  should
	      leave it blank.

       ACNAME If  this	is  not blank, then it is passed with the -C option to pppoe.  It specifies the name of the access concentrator to connect
	      to.  Usually, you should leave it blank.

       DEMAND If set to a number, the link is activated on demand and brought down after after DEMAND seconds.	If set to no, the link is kept	up
	      all the time rather than being activated on demand.

       DNSTYPE
	      One  of NOCHANGE, SPECIFY or SERVER.  If set to NOCHANGE, adsl-connect will not adjust the DNS setup in any way.	If set to SPECIFY,
	      it will re-write /etc/resolv.conf with the values of DNS1 and DNS2.  If set to SERVER, it will supply the usepeerdns option to pppd,
	      and make a symlink from /etc/resolv.conf to /etc/ppp/resolv.conf.

       DNS1, DNS2
	      IP addresses of DNS servers if you use DNSTYPE=SPECIFY.

       USERCTL
	      If the line USERCTL=yes (exactly like that; no whitespace or comments) appears in the configuration file, then /sbin/ifup will allow
	      non-root users to bring the conneciton up or down.

       PEERDNS
	      If set to "yes", then adsl-connect will supply the usepeerdns option to pppd, which causes it to obtain DNS  server  addresses  from
	      the  peer  and  create  a  new /etc/resolv.conf file.  Otherwise, adsl-connect will not supply this option, and pppd will not modify
	      /etc/resolv.conf.

       CONNECT_POLL
	      How often (in seconds) adsl-start should check to see if a new PPP interface has come up.  If this is set to 0, the adsl-start  sim-
	      ply initiates the PPP session, but does not wait to see if it comes up successfully.

       CONNECT_TIMEOUT
	      How  long  (in seconds) adsl-start should wait for a new PPP interface to come up before concluding that adsl-connect has failed and
	      killing the session.

       PING   A character which is echoed every CONNECT_POLL seconds while adsl-start is waiting for the PPP interface to come up.

       FORCEPING
	      A character which is echoed every CONNECT_POLL seconds while adsl-start is waiting for the PPP interface to  come  up.   Similar	to
	      PING, but the character is echoed even if adsl-start's standard output is not a tty.

       PIDFILE
	      A  file in which to write the process-ID of the adsl-connect process (for example, /var/run/pppoe.pid).  Two additional files ($PID-
	      FILE.pppd and $PIDFILE.pppoe) hold the process-ID's of the pppd and pppoe processes, respectively.

       SYNCHRONOUS
	      An indication of whether or not to use synchronous PPP (yes or no).  Synchronous PPP is safe on Linux machines with the n_hdlc  line
	      discipline.   (If you have a file called "n_hdlc.o" in your modules directory, you have the line discipline.)  It is not recommended
	      on other machines or on Linux machines without the n_hdlc line discipline due to some known and unsolveable  race  conditions  in  a
	      user-mode client.

       CLAMPMSS
	      The value at which to "clamp" the advertised MSS for TCP sessions.  The default of 1412 should be fine.

       LCP_INTERVAL
	      How often (in seconds) pppd sends out LCP echo-request packets.

       LCP_FAILURE
	      How many unanswered LCP echo-requests must occur before pppd concludes the link is dead.

       PPPOE_TIMEOUT
	      If this many seconds elapse without any activity seen by pppoe, then pppoe exits.

       FIREWALL
	      One  of  NONE, STANDALONE or MASQUERADE.	If NONE, then adsl-connect does not add any firewall rules.  If STANDALONE, then it clears
	      existing firewall rules and sets up basic rules for a standalone machine.  If MASQUERADE, then it clears existing firewall rules and
	      sets  up	basic  rules  for an Internet gateway.	If you run services on your machine, these simple firewall scripts are inadequate;
	      you'll have to make your own firewall rules and set FIREWALL to NONE.

       PPPOE_EXTRA
	      Any extra arguments to pass to pppoe

       PPPD_EXTRA
	      Any extra arguments to pass to pppd

       LINUX_PLUGIN
	      If non-blank, the full path of the Linux kernel-mode PPPoE plugin (typically /etc/ppp/plugins/rp-pppoe.so.)  This  forces  adsl-con-
	      nect  to	use  kernel-mode PPPoE on Linux 2.4.x systems.	This code is experimental and unsupported.  Use of the plugin causes adsl-
	      connect to ignore CLAMPMSS, PPPOE_EXTRA, SYNCHRONOUS and PPPOE_TIMEOUT.

       By using different configuration files with different PIDFILE settings, you can manage multiple PPPoE connections.  Just specify  the  con-
       figuration file as an argument to adsl-start and adsl-stop.
