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。
