netstat -s 命令 引數
netstat -s是一個用於顯示網路統計資訊的命令。它會列出各種網路協議的統計資料，包括接收和傳送的資料包數量、錯誤資訊、連線狀態等。透過檢視這些統計資訊，可以瞭解系統網路的執行情況，幫助診斷網路問題和最佳化網路效能。
這個命令的輸出可以幫助管理員監控網路活動，識別潛在的問題，比如網路擁塞、連線異常、資料包丟失等。透過分析這些統計資訊，可以及時採取措施來解決網路故障或改進網路效能。
使用netstat -s命令需要相應的許可權，通常需要以管理員身份或root使用者來執行。在處理網路問題時，這個命令可以提供有用的資訊，但需要正確解讀和分析結果，以便有效地解決網路相關的挑戰。
以下是輸出結果：
