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).
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。
注意:这个答案是huntharo和JasonXA的答案和评论组合在一起，并进行了简化，以方便读者阅读。例子来自CurrPorts的网页。
如果你在Windows 8、Windows Server 2012或更高版本上运行，并安装了PowerShell v4以上版本，你可以使用下面的脚本。它会发现与端口相关的进程并终止它们(即终止进程及其连接;不仅仅是联系)。
Code
#which port do you want to kill
[int]$portOfInterest = 80
#fetch the process ids related to this port
[int[]]$processId = Get-NetTCPConnection -LocalPort $portOfInterest |
Select-Object -ExpandProperty OwningProcess -Unique |
Where-Object {$_ -gt 0}
#kill those processes
Stop-Process -Id $processId
文档:
get - netttcpconnection - PowerShell的NetStat等效程序
选择对象-从对象中拉回特定属性/删除重复项
Where-Object -根据某些条件筛选值
Stop-Process - PowerShell的TaskKill等效程序
