Windows Embedded下的網絡監測工具(三)
Netstat命令
接下來是netstat，顯示網絡當前的狀態。輸入s netstat -e /d，顯示以太網的統計數據，比如發送和接收到的字節數等。

輸入s s netstat -n /d,會顯示當前活動的TCP連接，包括地址和端口號：
471308 PID:53a0062 TID:53b0062 GetTcpTable.
471308 PID:53a0062 TID:53b0062

471309 PID:53a0062 TID:53b0062 0.0.0.0 138
輸入s netstat -p tcp /d，會顯示指定網絡協議的信息，如下：

-s選項顯示各種協議的統計信息，比如IP, IPv6, ICMP, ICMPv6, TCP, TCPv6, UDP和UDPv6協議。-p可以和-s共同使用，用于顯示某種協議的統計信息。
-r選項則顯示路由表信息，與后邊的route print命令類似。
Route命令
輸入s route print /d，顯示當前的路由表信息：

Route除了print命令外，還有Add和Delete命令。大家可以參考Route的幫助，我們就不多解釋了。
Tracert命令
Tracert命令用于跟蹤你的設備到某個IP地址的路由。輸入s Tracert www.sohu.com –p，需要說明的是，Tracert結果輸入到output的參數是-p。

好了，對于Windows CE上的網絡監測工具，我們就先介紹到這里。我們將在后邊繼續介紹另一個功能強大的網絡檢測工具——netlog。
