The debug output is written # to syslog LOG_LOCAL2. debug # 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 # noauth means do not require the peer to authenticate itself, this must # be set if you want to use pppd to connect to the internet.

If you use wvdial, set the ISDN parameter in /etc/wvdial.conf # instead. #default-asyncmap # 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). The value 1492 is for DSL connections (PPP Default - # PPPoE Header: 1500 - 8 = 1492) mru 1492 （要加上找個） # 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. The value 1492 is for DSL connections # (PPP Default - PPPoE Header: 1500 - 8 = 1492) mtu 1492 （找個也要加上） # Set the interface netmask to , a 32 bit netmask in "decimal dot" # notation (e.g. 255.255.255.0). #netmask 255.255.255.0 # Don't fork to become a background process (otherwise pppd will do so # if a serial device is specified). nodetach # If this option is given, pppd will send an LCP echo-request frame to # the peer every n seconds.
