    这是我做的：
  
  
    确保“openvswitch-testcontroller”已关闭：
  
   <pre>
 <code>
 yavuz@ubuntu:/tmp$ service --status-all | grep openv
 [ + ] openvswitch-switch
 [ - ] openvswitch-testcontroller

</code>
 </pre>
  
    运行ryu应用程序：
  
   <pre>
 <code>
 yavuz@ubuntu:~/ryu$ pwd
/home/yavuz/ryu
yavuz@ubuntu:~/ryu$ sudo ryu-manager --verbose ryu/app/example_switch_13.py
lzma module is not available
Registered VCS backend: git
Registered VCS backend: hg
Registered VCS backend: svn
Registered VCS backend: bzr
loading app ryu/app/example_switch_13.py

</code>
 </pre>
  
    mininet之前运行tcpdump for lo（不是eth0或类似的）
  
   <pre>
 <code>
 sudo tcpdump -i lo -w ryu-local.cap

</code>
 </pre>
  
    运行mininet：
  
   <pre>
 <code>
 yavuz@ubuntu:/tmp$ sudo mn --topo single,3 --controller=remote --mac

</code>
 </pre>
  
    停止跟踪并打开它。
