My first Ryu application [ 需要修正 path ]

from ryu.base import app_manager

class L2Switch(app_manager.RyuApp):
    def __init__(self, *args, **kwargs):
        super(L2Switch, self).__init__(*args, **kwargs)

.py檔須要創建在主目錄底下,不可以放在自己創的資料夾

===================================

docker裝centos時不會安裝ifconfig,netstat等工具

yum install net-tools

接著裝封包監控軟體wireshark

yum install wireshark 

安裝抓包軟體tcpdump

yum install tcpdump
