linux adsl 拨号自动配置脚本的方法

在使用动态vps服务器的时候发现一枚已经写好的自动配置拨号的shell脚本，分享一下，免去手动配置的烦恼，代码如下

#! /bin/sh
path=/usr/lib64/qt-3.3/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin
log=/var/log/pppoe.log
sed -i '/^gateway/d' /etc/sysconfig/network-scripts/ifcfg-eth0
sed -i '/^dns1/d' /etc/sysconfig/network-scripts/ifcfg-eth0
sed -i '/^dns2/d' /etc/sysconfig/network-scripts/ifcfg-eth0

echo "del ifcfg-eth0 gateway ...... success" > $log
echo "del ifcfg-eth0 dns1   ...... success" >> $log
echo "del ifcfg-eth0 dns2   ...... success" >> $log

read -p "请输入adsl帐号:" id
read -p "请输入adsl密码:" ps

sed -i 's/root/'$id'/g' /etc/ppp/chap-secrets
sed -i 's/12345/'$ps'/g' /etc/ppp/chap-secrets

echo "modify chap-secrets  ...... success" >>$log

sed -i 's/root/'$id'/g' /etc/ppp/pap-secrets
sed -i 's/12345/'$ps'/g' /etc/ppp/pap-secrets

echo "modify pap-secrets   ......success" >>$log

sed -i 's/root/'$id'/g' /etc/sysconfig/network-scripts/ifcfg-ppp0

echo "modify ifcfg-ppp0   ......success" >>$log

echo nameserver 114.114.114.114 >> /etc/resolv.conf
echo nameserver 8.8.8.8 >> /etc/resolv.conf

systemctl restart network.service 

cat $log
exit
