有人知道如何通过windows命令行关闭单个连接的TCP或UDP套接字吗?

我在谷歌上搜索了一下,看到一些人也问了同样的问题。但是答案看起来像是netstat或netsh命令的手册页,重点关注如何监视端口。我不想要关于如何监控它们的答案(我已经这样做了)。我想干掉他们。

EDIT, for clarification: Let's say that my server listens TCP port 80. A client makes a connection and port 56789 is allocated for it. Then, I discover that this connection is undesired (e.g. this user is doing bad things, we asked them to stop but the connection didn't get dropped somewhere along the way). Normally, I would add a firewall to do the job, but this would take some time, and I was in an emergency situation. Killing the process that owns the connection is really a bad idea here because this would take down the server (all users would lose functionality when we just want to selectively and temporally drop this one connection).


当前回答

您可以使用sysinternal中的tcpview等程序。我想它可以帮助您监控和消除不必要的连接。

其他回答

是的,有可能关闭TCP或UDP端口,在DOS中有一个命令

TASKKILL /f /pid 1234 

我希望这对你有用

我找到了正确答案。尝试Sysinternals中的TCPView,现在由微软拥有。你可以在http://technet.microsoft.com/en-us/sysinternals/bb897437上找到它

例如,您希望释放端口8080 然后,按照这些命令执行。

 netstat -ano
 taskkill /f /im [PID of the port 8080 got from previous command]

完成了!

尝试Sysinternals/Microsoft的工具TCPView (GUI)和Tcpvcon(命令行)。 https://learn.microsoft.com/en-us/sysinternals/downloads/tcpview

使用CurrPorts(免费且无需安装):http://www.nirsoft.net/utils/cports.html

/close <本端地址> <本端端口> <对端地址> <对端端口>{进程名}

例子:

# Close all connections with remote port 80 and remote address 192.168.1.10: 
/close * * 192.168.1.10 80
# Close all connections with remote port 80 (for all remote addresses): 
/close * * * 80
# Close all connections to remote address 192.168.20.30: 
/close * * 192.168.20.30 *
# Close all connections with local port 80: 
/close * 80 * *
# Close all connections of Firefox with remote port 80: 
/close * * * 80 firefox.exe

它还有一个很好的GUI,具有搜索和筛选功能。
