2.1 启动 TCP echo server 在命令行运行 deno run --allow-net ./echo_server.ts 命令后,当前命令行会输出以下信息: listening on 0.0.0.0:8080 1. 表示我们的 TCP echo server 已经开始监听本机的8080端口,这里我们可以使用 netstat 命令,来打印 Linux 中网络系统的状态信息: ...

对于Windows 7 和 Windows Server 2008 R2,可以使用以下脚本以定义的频率收集 netstat 输出。 从输出中,可以看到端口使用趋势。 控制台 @ECHO ON set v=%1 :loop set /a v+=1 ECHO %date% %time% >> netstat.txt netstat -ano >> netstat.txt PING 1.1.1.1 -n 1 -w 60000 >NUL goto loop ...
wiced_tcp_disconnect(&tcp_client_socket); return WICED_ERROR; } wiced_packet_delete(packet); return WICED_SUCCESS; } In application_start(), I am calling this function every 500ms using a register timed event. I am using the tcp_echo_server.py given by snip.tcp_client as server. In...
1. What is the largest segment size that will work for both client and server? 2. Where was the capture taken (Client local/SPAN/TAP/Server local)? 3. What is the initial round trip time of the connection? 4. How many router hops are between client and server? 5. Why does the tra...

For Windows 7 and Windows Server 2008 R2, you can use the below script to collect the netstat output at defined frequency. From the outputs, you can see the port usage trend. ConsoleCopy @ECHO ON set v=%1 :loop set /a v+=1 ECHO %date% %time% >> netstat.txt netstat -ano >> ...
The following tutorial uses the "multiplexed version" as an example to illustrate how to use it. The intranet penetration consists of three parts: client, server, and bridge; client and server actively connect to the bridge for bridging.
