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:
- #!/bin/sh
- 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:
- #!/bin/sh
- ######################################################################
- #
- # Determine the device to be terminated.
- #
- if [ "$1" = "" ]; then
- DEVICE=ppp0
- else
- DEVICE=$1
- fi
- ######################################################################
- #
- # If the ppp0 pid file is present then the program is running. Stop it.
- if [ -r /var/run/$DEVICE.pid ]; then
- kill -INT `cat /var/run/$DEVICE.pid`
- #
- # If the kill did not work then there is no process running for this
- # pid. It may also mean that the lock file will be left. You may wish
- # to delete the lock file at the same time.
- if [ ! "$?" = "0" ]; then
- rm -f /var/run/$DEVICE.pid
- echo "ERROR: Removed stale pid file"
- exit 1
- fi
- #
- # Success. Let pppd clean up its own junk.
- echo "PPP link to $DEVICE terminated."
- exit 0
- fi
- #
- # The ppp process is not running for ppp0
- echo "ERROR: PPP link is not active on $DEVICE"
- exit 1
chat-script:
- #!/bin/sh
- exec chat -v \
- TIMEOUT 5 \
- ABORT "BUSY" \
- ABORT "ERROR" \
- ABORT "NO CARRIER" \
- '' \rAT \
- OK 'AT+CGDCONT=1,"IP","CMNET"' \
- OK 'ATDT*99***1#' \
- CONNECT '' \
设置DNS的resove.conf:
- nameserver 211.136.20.203
- 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。
