在过去的3个月左右,我遇到了随机错误,我无法绑定我的本地开发工作站上运行Identity Server的特定端口.起初我以为这是我的破机,所以我重置了一切,这有点解决了2个月的问题,现在又回来了.
与此同时,其他开发者也看到了同样的问题.遇到此问题的所有人都在运行Windows 10,但并非所有使用Windows 10的人都有此问题.
使用shutdown / s / f / t 0关闭后重新启动Windows是再次打开端口的唯一可靠解决方案.我正常重启后(由于Windows更新或类似),问题再次出现,我需要用该命令关闭窗口.
我写了一个小的f#脚本来测试哪些端口受到影响.我得到的确切错误消息是
An attempt was made to access a socket in a way forbidden by its access permissions
当我找到它时,建议的解决方案在哪里重新启动机器,但这似乎更像是一个解决方案,而不是一个真正的解决方案.我也发现了https://stackoverflow.com/a/10461978/621366 – 但netstat -o没有列出端口,TCPView工具也没有.我们所有人都非常确定该端口没有任何东西占用.我还尝试在管理员控制台中运行netstat,在Windows上的bash中运行类似的命令,但找不到任何东西.我甚至无法通过telnet连接到端口,它说什么都没有在端口上监听.
这些端口例如是：
> 49670 – 49689
> 49710 – 49749
> 49760 – 49779
> 49811 – 49830
> 49843 – 49882
> 50197 – 50216
我们没有人修改Windows防火墙上的任何东西或安装任何其他防病毒工具,除了Windows 10默认工具.所以一切都应该是默认值.并且它在第一次打破之前和之后的2个月之后也正常工作了大约10个月.在这两种情况下,安装后的一些Windows更新.最后一次是bios更新(可能是因为崩溃/幽灵问题？).
还试图在防火墙上明确打开端口没有帮助.
根据这个答案https://stackoverflow.com/a/23982901/621366 TCPView和netstat不应该错过任何被占用的端口,但即使我在TCPView中启用显示未连接的端点,我也没有看到任何在尝试绑定它时获得权限被拒绝的端口.这里是一个来自占用端口的屏幕(我标记了在允许拒绝端口组之前或之后的边界占用端口)
更新：
我注意到它似乎总是160或180(确切数字)的端口,在40,000范围内有权限被拒绝这对我来说似乎很奇怪,所以很明显有些东西是故意占用端口,但是什么？我似乎无法在Windows事件日志中找到任何内容(虽然我不知道要查找什么)并且这些端口都没有显示任何我的防火墙规则.同时关闭docker for windows并没有任何区别,当一位同事提到对他们来说,足以重启docker for windows(在UI中重启 – 重新启动),现在对我来说,甚至重启与关机命令不再起作用.
更新2：
netstat -ano的输出从管理员PowerShell运行：

我实际想要打开的端口是49786,但是我的小测试算法拒绝了报告的端口数量,但是在检查netstat时没有分配的端口令我感到困惑
更新3：
现在只是运行shutdown / s / f / t 0不再起作用了,我发现另一种解决方法似乎在https://social.technet.microsoft.com/Forums/windows/en-US/e0cc1b3e-2c63-451a-abc8-8e1e66a23287/an-attempt-was-made-to-access-a-socket-in-a-way-forbidden-by-its-access-permissions?forum=w7itpronetworking中相当可靠 – netsh int ip reset并重新启动计算机(正常的Windows 10重启就足够了)到目前为止,该端口始终可用于下一次启动(但只有3次尝试)
更新4：
意见总结：
>在小f#脚本中设置SO_REUSEADDR会使事情变得更糟
>试图关闭Skype,VPN应用程序,DropBox和类似没有任何影响(是的,我实际上确保进程终止)
当我找到它时,解释是
An attempt was made to access a socket in a way forbidden by its access permissions. An example is using a broadcast address for sendto without broadcast permission being set using setsockopt(SO_broADCAST).
Another possible reason for the WSAEACCES error is that when the bind function is called (on Windows NT 4.0 with SP4 and later),another application,service,or kernel mode driver is bound to the same address with exclusive access. Such exclusive access is a new feature of Windows NT 4.0 with SP4 and later,and is implemented by using the SO_EXCLUSIVEADDRUSE option.
