Jetson TX2 shell脚本自动修改IP及DNS

Jetson TX2 shell脚本自动修改IP及DNS

IP地址修改路径：/etc/network/interfaces

DNS修改路径：/etc/resolv.conf

- shell脚本

//ipdndconfig.sh

#!/bin/sh 

#Define Path 定义变量，可以根据实际情况修改 
 ETHCONF=/etc/network/interfaces.d/interfaces
 DNSCONF=/etc/resolv.conf
 DIR1=/etc/network/interfaces.d/`date +%Y%m%d`
 DIR2=/etc/resolv.conf.bak

echo "================================================"

{

  cp $ETHCONF $DIR1
 #选择网口
  read -p "Please insert eth×:" ETH
  case $ETH in

//ipconf.sh

#!/bin/sh 

RC=/etc/init.d/rc.local
#出现兼容问题时使用
#sudo dpkg-reconfigure dash
sudo ./ipdnsconf.sh

#在rc.local里加入重启网络配置的命使配置生效
#sed '$a sudo /etc/init.d/networking restart' $RC
#sed '$a sudo /etc/init.d/resolvconf restart' $RC
