Which command, depending on its options, can display the open network connections, the routing tables, as well as network interface statistics. (Specify ONLY the command without any path or parameters.)
Answer: netstat 或 ss
題解
「netstat」(/bin/netstat)指令可以顯示出網路連線、路由表、介面統計、偽裝連線和多播成員的資訊。「ss」(/bin/ss)指令與「netstat」類似,但可以顯示出更詳細的資料。
