  在之前的《Linux内核PPP套件设置》一文中,我们已经讲解了相关的一些PPP套件设置操作。那么这里,我们依据前文的一些内容,再来详细讲解一下arm上成功实现ppp拨号脚本的过程。

  arm上成功实现ppp拨号脚本

  ppp-on:

  1.#!/bin/sh

  2.pppd modem -d -detach lock /dev/ttySAC0 19200 kdebug 4 file /etc/ppp/options crtscts noipdefault netmask 255.255.255.0 defaultroute connect /etc/ppp/chat-script

  ppp-off:

  1.#!/bin/sh

  2.######################################################################

  3.#

  4.# Determine the device to be terminated.

  5.#

  6.if [ "$1" = "" ]; then

  7.DEVICE=ppp0

  8.else

  9.DEVICE=$1

  10.fi

  11.

  12.######################################################################

  13.#

  14.# If the ppp0 pid file is present then the program is running. Stop it.

  15.if [ -r /var/run/$DEVICE.pid ]; then

  16.  kill -INT `cat /var/run/$DEVICE.pid`

  17.#

  18.# If the kill did not work then there is no process running for this

  19.# pid. It may also mean that the lock file will be left. You may wish

  20.# to delete the lock file at the same time.

  21.  if [ ! "$?" = "0" ]; then

  22.    rm -f /var/run/$DEVICE.pid

  23.    echo "ERROR: Removed stale pid file"

  24.    exit 1

  25.  fi

  26.#

  27.# Success. Let pppd clean up its own junk.

  28.  echo "PPP link to $DEVICE terminated."

  29.  exit 0

  30.fi

  31.#

  32.# The ppp process is not running for ppp0

  33.echo "ERROR: PPP link is not active on $DEVICE"

  34.exit 1

  chat-script:

  1.#!/bin/sh

  2.exec chat -v \

  3.TIMEOUT 5 \

  4.ABORT   "BUSY" \

  5.ABORT   "ERROR" \

  6.ABORT   "NO CARRIER" \

  7.'' \rAT   \

  8.OK 'AT+CGDCONT=1,"IP","CMNET"' \

  9.OK 'ATDT*99***1#' \

  10.CONNECT '' \

  设置DNS的resove.conf:

  1.nameserver 211.136.20.203

  2.nameserver 211.136.17.107

  到此,arm ppp拨号脚本就设置好了。那么希望本文的代码展示,能够让大家对此有所了解。
