Ubuntu修改网卡配置文件：
vim /etc/network/interfaces<pre name="code" class="plain">cat /etc/network/interfaces
auto eth0
iface eth0 inet static
address 192.168.1.41
gateway 192.168.1.1
netmask 255.255.255.0
dns-nameserver 114.114.114.114
然后重启网卡：
ifdown eth0 ifup eth0
VMware下安装的Linux虚拟机ping网关和baidu.com出现下面情况：
64 bytes from 192.168.20.254: icmp_seq=1 ttl=128 time=2460 ms (DUP!) 64 bytes from 192.168.20.254: icmp_seq=1 ttl=128 time=2460 ms (DUP!)
重启VMware的网络：VMnet1 和VMnet8以后解决了问题
ubuntu安装开启启动管理软件：
apt-get install sysv-rc-conf
