# /etc/ppp/options # # Originally created by Jim Knoble # Modified for Debian by alvar Bray # Modified for PPP Server setup by Christoph Lameter # Modified for ArchLinux by Manolis Tzanidakis # # To quickly see what options are active in this file, use this command: # grep -Ev '#|^ *$' /etc/ppp/options # Specify which DNS Servers the incoming Win95 or WinNT Connection should use # Two Servers can be remotely configured # ms-dns 192.168.1.1 # ms-dns 192.168.1.2 # Specify which WINS Servers the incoming connection Win95 or WinNT should use # ms-wins 192.168.1.50 # ms-wins 192.168.1.51 # Run the executable or shell command specified after pppd has # terminated the link. This script could, for example, issue commands # to the modem to cause it to hang up if hardware modem control signals # were not available. #disconnect "chat -- \d+++\d\c OK ath0 OK" # async character map -- 32-bit hex; each bit is a character # that needs to be escaped for pppd to receive it. 0x00000001 # represents '\x01', and 0x80000000 represents '\x1f'. asyncmap 0 # Require the peer to authenticate itself before allowing network # packets to be sent or received. # Please do not disable this setting. It is expected to be standard in # future releases of pppd. Use the call option (see manpage) to disable # authentication for specific peers. auth # Use hardware flow control (i.e. RTS/CTS) to control the flow of data # on the serial port. crtscts # Use software flow control (i.e. XON/XOFF) to control the flow of data # on the serial port. #xonxoff # Specifies that certain characters should be escaped on transmission # (regardless of whether the peer requests them to be escaped with its # async control character map). The characters to be escaped are # specified as a list of hex numbers separated by commas. Note that # almost any character can be specified for the escape option, unlike # the asyncmap option which only allows control characters to be # specified. The characters which may not be escaped are those with hex # values 0x20 - 0x3f or 0x5e. #escape 11,13,ff # Don't use the modem control lines. #local # Specifies that pppd should use a UUCP-style lock on the serial device # to ensure exclusive access to the device. lock # Don't show the passwords when logging the contents of PAP packets. # This is the default. hide-password # When logging the contents of PAP packets, this option causes pppd to # show the password string in the log message. #show-password # Use the modem control lines. On Ultrix, this option implies hardware # flow control, as for the crtscts option. (This option is not fully # implemented.) modem # Set the MRU [Maximum Receive Unit] value to for negotiation. pppd # will ask the peer to send packets of no more than bytes. The # minimum MRU value is 128. The default MRU value is 1500. A value of # 296 is recommended for slow links (40 bytes for TCP/IP header + 256 # bytes of data). #mru 542 # Set the interface netmask to , a 32 bit netmask in "decimal dot" # notation (e.g. 255.255.255.0). #netmask 255.255.255.0 # Disables the default behaviour when no local IP address is specified, # which is to determine (if possible) the local IP address from the # hostname. With this option, the peer will have to supply the local IP # address during IPCP negotiation (unless it specified explicitly on the # command line or in an options file). #noipdefault # Enables the "passive" option in the LCP. With this option, pppd will # attempt to initiate a connection; if no reply is received from the # peer, pppd will then just wait passively for a valid LCP packet from # the peer (instead of exiting, as it does without this option). #passive # With this option, pppd will not transmit LCP packets to initiate a # connection until a valid LCP packet is received from the peer (as for # the "passive" option with old versions of pppd). #silent # Don't request or allow negotiation of any options for LCP and IPCP # (use default values). #-all # Disable Address/Control compression negotiation (use default, i.e. # address/control field disabled). #-ac # Disable asyncmap negotiation (use the default asyncmap, i.e. escape # all control characters). #-am # Don't fork to become a background process (otherwise pppd will do so # if a serial device is specified). #-detach # Disable IP address negotiation (with this option, the remote IP # address must be specified with an option on the command line or in # an options file). #-ip # Disable IPCP negotiation and IP communication. This option should # only be required if the peer is buggy and gets confused by requests # from pppd for IPCP negotiation. #noip # Disable magic number negotiation. With this option, pppd cannot # detect a looped-back line. #-mn # Disable MRU [Maximum Receive Unit] negotiation (use default, i.e. # 1500). #-mru # Disable protocol field compression negotiation (use default, i.e. # protocol field compression disabled). #-pc # Require the peer to authenticate itself using PAP. #+pap # Don't agree to authenticate using PAP. #-pap # Require the peer to authenticate itself using CHAP [Cryptographic # Handshake Authentication Protocol] authentication. #+chap # Don't agree to authenticate using CHAP. #-chap # Disable negotiation of Van Jacobson style IP header compression (use # default, i.e. no compression). #-vj # Increase debugging level (same as -d). If this option is given, pppd # will log the contents of all control packets sent or received in a # readable form. The packets are logged through syslog with facility # daemon and level debug. This information can be directed to a file by # setting up /etc/syslog.conf appropriately (see syslog.conf(5)). (If # pppd is compiled with extra debugging enabled, it will log messages # using facility local2 instead of daemon). #debug # Append the domain name to the local host name for authentication # purposes. For example, if gethostname() returns the name porsche, # but the fully qualified domain name is porsche.Quotron.COM, you would # use the domain option to set the domain name to Quotron.COM. #domain # Enable debugging code in the kernel-level PPP driver. The argument n # is a number which is the sum of the following values: 1 to enable # general debug messages, 2 to request that the contents of received # packets be printed, and 4 to request that the contents of transmitted # packets be printed. #kdebug n # Set the MTU [Maximum Transmit Unit] value to . Unless the peer # requests a smaller value via MRU negotiation, pppd will request that # the kernel networking code send data packets of no more than n bytes # through the PPP network interface. #mtu # Set the name of the local system for authentication purposes to . # This is a privileged option. With this option, pppd will use lines in the # secrets files which have as the second field when looking for a # secret to use in authenticating the peer. In addition, unless overridden # with the user option, will be used as the name to send to the peer # when authenticating the local system to the peer. (Note that pppd does # not append the domain name to .) #name # Enforce the use of the hostname as the name of the local system for # authentication purposes (overrides the name option). #usehostname # Set the assumed name of the remote system for authentication purposes # to . #remotename # Add an entry to this system's ARP [Address Resolution Protocol] # table with the IP address of the peer and the Ethernet address of this # system. proxyarp # Use the system password database for authenticating the peer using # PAP. Note: mgetty already provides this option. If this is specified # then dialin from users using a script under Linux to fire up ppp wont work. # login # If this option is given, pppd will send an LCP echo-request frame to the # peer every n seconds. Normally the peer should respond to the echo-request # by sending an echo-reply. This option can be used with the # lcp-echo-failure option to detect that the peer is no longer connected. lcp-echo-interval 30 # If this option is given, pppd will presume the peer to be dead if n # LCP echo-requests are sent without receiving a valid LCP echo-reply. # If this happens, pppd will terminate the connection. Use of this # option requires a non-zero value for the lcp-echo-interval parameter. # This option can be used to enable pppd to terminate after the physical # connection has been broken (e.g., the modem has hung up) in # situations where no hardware modem control lines are available. lcp-echo-failure 4 # Set the LCP restart interval (retransmission timeout) to seconds # (default 3). #lcp-restart # Set the maximum number of LCP terminate-request transmissions to # (default 3). #lcp-max-terminate # Set the maximum number of LCP configure-request transmissions to # (default 10). #lcp-max-configure # Set the maximum number of LCP configure-NAKs returned before starting # to send configure-Rejects instead to (default 10). #lcp-max-failure # Set the IPCP restart interval (retransmission timeout) to # seconds (default 3). #ipcp-restart # Set the maximum number of IPCP terminate-request transmissions to # (default 3). #ipcp-max-terminate # Set the maximum number of IPCP configure-request transmissions to # (default 10). #ipcp-max-configure # Set the maximum number of IPCP configure-NAKs returned before starting # to send configure-Rejects instead to (default 10). #ipcp-max-failure # Set the PAP restart interval (retransmission timeout) to seconds # (default 3). #pap-restart # Set the maximum number of PAP authenticate-request transmissions to # (default 10). #pap-max-authreq # Set the maximum time that pppd will wait for the peer to authenticate # itself with PAP to seconds (0 means no limit). #pap-timeout # Set the CHAP restart interval (retransmission timeout for # challenges) to seconds (default 3). #chap-restart # Set the maximum number of CHAP challenge transmissions to # (default 10). #chap-max-challenge # If this option is given, pppd will rechallenge the peer every # seconds. #chap-interval # With this option, pppd will accept the peer's idea of our local IP # address, even if the local IP address was specified in an option. #ipcp-accept-local # With this option, pppd will accept the peer's idea of its (remote) IP # address, even if the remote IP address was specified in an option. #ipcp-accept-remote # Disable the IPXCP and IPX protocols. # To let pppd pass IPX packets comment this out --- you'll probably also # want to install ipxripd, and have the Internal IPX Network option enabled # in your kernel. /usr/doc/HOWTO/IPX-HOWTO.gz contains more info. noipx # Exit once a connection has been made and terminated. This is the default, # unless the `persist' or `demand' option has been specified. #nopersist # Do not exit after a connection is terminated; instead try to reopen # the connection. #persist # Terminate after n consecutive failed connection attempts. # A value of 0 means no limit. The default value is 10. #maxfail # Initiate the link only on demand, i.e. when data traffic is present. # With this option, the remote IP address must be specified by the user on # the command line or in an options file. Pppd will initially configure # the interface and enable it for IP traffic without connecting to the peer. # When traffic is available, pppd will connect to the peer and perform # negotiation, authentication, etc. When this is completed, pppd will # commence passing data packets (i.e., IP packets) across the link. #demand # Specifies that pppd should disconnect if the link is idle for seconds. # The link is idle when no data packets (i.e. IP packets) are being sent or # received. Note: it is not advisable to use this option with the persist # option without the demand option. If the active-filter option is given, # data packets which are rejected by the specified activity filter also # count as the link being idle. #idle # Specifies how many seconds to wait before re-initiating the link after # it terminates. This option only has any effect if the persist or demand # option is used. The holdoff period is not applied if the link was # terminated because it was idle. #holdoff # Wait for up n milliseconds after the connect script finishes for a valid # PPP packet from the peer. At the end of this time, or when a valid PPP # packet is received from the peer, pppd will commence negotiation by # sending its first LCP packet. The default value is 1000 (1 second). # This wait period only applies if the connect or pty option is used. #connect-delay # Packet filtering: for more information, see pppd(8) # Any packets matching the filter expression will be interpreted as link # activity, and will cause a "demand" connection to be activated, and reset # the idle connection timer. (idle option) # The filter expression is akin to that of tcpdump(1) #active-filter # uncomment the line below this if you use PPPoE #plugin /usr/lib/pppd/plugins/pppoe.so # ------
