求助，ub下修改ip地址问题

[zjxfly]

在/etc/network/interfaces

下修改了ip地址，网关
居然用ifconfig查看是只变了ip，没有变化网管
之前是192.168.1.16，gw：192.168.1.1
修改为192.168.0.16，gw：192.168.0.1
但是查看的时候不一样；

eth0 inet 192.168.0.16 Bcast:192.168.1.255 mask:255.255.255.0


这里的bcast 不该变成192.168.0.255吗！！！！，现在看的还是修改之前的那个地址！！

请大虾们帮我一下啦，什么情况呢。。。。/etc/network/interfaces
中静态地址明明是192.168.0.1，怎么ifconfig查看的时候还是原来的呢！

/etc/network/interfaces

把下面的指令 複製 貼進終端機 執行
1. sudo cat /etc/network/interfaces
2. sudo ifconfig -a
3. sudo route -n -v
把結果 直接全部複製貼上來

你是想設定這個嗎 ?

https://philipzheng.gitbooks.io/docker_ ... d_network/

/etc/network/interfaces
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo eth0 eth0:1
iface lo inet loopback
iface eth0 inet static
address 192.168.0.16
netmask 255.255.254.0
gateway 192.168.0.1
iface eth0:1 inet static
address 10.2.0.2
netmask 255.255.255.0

你如此設定的資料 如果有參考什麼網頁 請提供網址 可以節省一些時間

[zjxfly]

我在修改之前是能上网的。。
路由器的网关变了，所以修改了ip就是那个网卡的网关地址即使修改了，可是ifconfig看到的还是原来的。。
