arm上实现PPP拨号脚本

2015-06-28 00:00作者:网管联盟

  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。
