如何在Mininet中修改host的IP地址

I got it! do like this:

mininet>py h1.setIP('10.0.0.3/24')

mininet>py h2.setIP('10.0.0.4/24')

mininet>h1 ping h2

PING 10.0.0.4(10.0.0.4)56(84) bytes of data.

64 bytes from10.0.0.4: icmp_req=1 ttl=64 time=2.38 ms

Hi everyone,

When I change host's IP, other hosts cannot ping through it, but it can ping other host.

And I find that, when typing in dump command, it shows that the IP is not changed.

That's why? How can I really change the ip of virtual host?

Thank you in advance for any answers.

在windows7 中安装xshell 和 xmanager4

在xshell中创建新会话（IP地址输入第1步中输入虚拟机中mininet VM的IP地址），选择“转发X11连接(X)”如下图：

转发X11连接(X)

其它按照常规设置即可。

3.测试

使用xshell登录虚拟机后输入xterm，xshell即可自动启动xmanager并将xterm显示在windows7下。

启动wireshark：

# wireshark &

即可看到wireshark的图形界面.
