linux自动切换Ip

也算是我自己的学以致用系列之一吧^_^

ubuntu:


#!/bin/bash
PS3="Select your network:"
echo "auto eth0" > /etc/network/interfaces
select choice in "home(dhcp)" "company(static)"
  do
    case "$REPLY" in
    1)
      echo "iface eth0 inet dhcp" >> /etc/network/interfaces
      break;;
    2)
      echo "iface eth0 inet static" >> /etc/network/interfaces
      echo "address 192.168.10.160" >> /etc/network/interfaces
      echo "netmask 255.255.255.0" >> /etc/network/interfaces
      echo "gateway 192.168.10.2" >> /etc/network/interfaces
      break;;
    *)
      echo -e "$REPLY is not a valid choice.Try again\n" 1>&2
      REPLY=
      ;;
    esac
  done
echo "auto lo" >> /etc/network/interfaces
echo "iface lo inet loopback" >> /etc/network/interfaces
/etc/init.d/networking restart

redhat,fedora,centos的:

#!/bin/bash
echo 'DEVICE=eth0' > /etc/sysconfig/network-scripts/ifcfg-eth0
echo 'ONBOOT=yes' >> /etc/sysconfig/network-scripts/ifcfg-eth0
echo 'TYPE=Ethernet' >> /etc/sysconfig/network-scripts/ifcfg-eth0
echo 'BOOTPROTO=static' >> /etc/sysconfig/network-scripts/ifcfg-eth0
if [ $1 = "home" ] ; then
echo 'IPADDR=192.168.10.160' >> /etc/sysconfig/network-scripts/ifcfg-eth0
echo 'NETMASK=255.255.255.0' >> /etc/sysconfig/network-scripts/ifcfg-eth0
echo 'GATEWAY=192.168.10.2' >> /etc/sysconfig/network-scripts/ifcfg-eth0
echo 'nameserver 202.96.69.38' > /etc/resolv.conf
else
echo 'IPADDR=10.0.0.2' >> /etc/sysconfig/network-scripts/ifcfg-eth0
echo 'NETMASK=255.0.0.0' >> /etc/sysconfig/network-scripts/ifcfg-eth0
echo 'GATEWAY=10.0.0.1' >> /etc/sysconfig/network-scripts/ifcfg-eth0
echo 'nameserver 10.0.0.100' > /etc/resolv.conf
fi;
service network restart

 

windows的

@echo off

goto menus~

:menus~
echo.
echo 请选择:
echo 1 切换到公司网
echo 2 切换到自动获取直接上网
echo.
set /p select=请输入菜单对应数字后回车:
if /i "%select%" == "1" goto neusoft
if /i "%select%" == "2" goto auto
goto menus~
