PsExec 在从非常简单的 c# 或 c++ 执行时挂起。 gui程序编译为“windows应用程序”
我在从编译为“Windows 应用程序”(而不是“控制台应用程序”)的非常简单的 c# 或 c++ gui 程序执行时遇到 PsExec 挂起。在下面 下面的 C) 部分我粘贴了代码来重现问题,而 D) 部分下我粘贴了 C++ 代码来重现相同的问题。
当 psexec 挂起时,本地附加到 psexec 后的 Windbg 输出将粘贴在 B) 部分下。
我的程序在转储 A) 部分下粘贴的输出后挂起。
如果您将 psexec 命令替换为任何本地命令,例如 ProcessStartInfo("cmd.exe", "/c dir c:\windows\*.*");,则该程序可以正常工作。
我想知道是否有人经历过并找到了解决方案。非常感谢您的帮助。
谢谢, Sharrajesh

I am experiencing PsExec hang while being executed from a very simple c# or c++ gui program compiled as "windows application" (not as "console application"). Under
section C) below I have pasted the code to reproduce the problem and under section D) I have pasted the c++ code to reproduce the same problem.
When the psexec hangs, the windbg output after being attached to psexec locally is pasted under section B).
My program hangs after dumping the output pasted under section A).
The program works fine if you replace psexec command with anything local e.g. ProcessStartInfo("cmd.exe", "/c dir c:\windows\*.*");
I was wondering if anybody experienced it and found the solution for it. Help will be greatly appreciated.
Thanks,
Sharrajesh

PSExec 对我来说太随意了。我没有花精力按照你的方式重现这个问题,但我通过使用“PAExec”避免了我的麻烦,它是一个看似有价值的精神继承者:
http://www.poweradmin.com/PAExec/
PSExec was hanging for me too randomly. I haven't put the effort into recreating the issue your way, but I have avoided my troubles by using "PAExec", a seemingly worthy successor in spirit:
http://www.poweradmin.com/PAExec/
我遇到了类似的问题,这是由于 eula 造成的,这可能是你的问题:
请参阅:
I had a similar problem that was due to the eula, which may be yours:
See: http://www.appdeploy.com/messageboards/tm.asp?m=72376&mpage=1&key=𑪸
Even though I had checked the EULA several times
还请在startInfo 上设置WorkingDirectory 属性,因为Sysinternals 实用程序使用文件的运行时解包,并且内核无法找到解包的(真正的)可执行文件。
Please also set the WorkingDirectory property on startInfo, as Sysinternals utilities use run-time unpacking of files and the kernel is unable to find the unpacked (real) exectutable file.
构建一个运行
PsExec
的通用控制台应用程序PsKill
和他们所有的朋友。通过代码调用此 ConsoleApp,而不是调用NotWorkingPsExec
方法,它就会正常工作。Build a generic Console Application which runs
PsExec
&PsKill
and all of their friends. Call this ConsoleApp through your code instead of calling theNotWorkingPsExec
method, and it'll work just fine.我对此有一个简单的解决方案,
C# 运行如下过程:
run.bat
是:psexec.bat
是:<前><代码>psexec.exe ................................
出口
I have a simple solution for this,
C# run the process like:
run.bat
is :psexec.bat
is:流上的同步读取有效:
即使在这里,请注意 ReadToEnd() 应在 WaitForExit() 之前完成。
我相信 PSExec 总是遇到这样的问题。在Java服务下运行时,我们过去将输出重定向到nul,无法获取正在运行的进程的输出,但可以获取PSExec本身的输出。
请参阅下面给出的讨论:

编辑:
关于 PSEXESVC 清理的注意事项:删除 C:\Windows (或 C:\Windows \system32 或两者)在终止挂起的 PSEXESVC 进程后。延迟的进程/文件会导致更多问题。
Synchronous read on the stream works:
Even here, note that the ReadToEnd() should be done before the WaitForExit().
I believe PSExec always had problems like this. When running under Java service, we used to redirect the output to nul and couldn't get the output of the running process, but can get the output of PSExec itself.
Refer to below given discussions:

http://forum.sysinternals.com/unusual-problem-with-psexecexe_topic6655.html
Edit:
Note on PSEXESVC cleanup: Delete the PSEXESVC.EXE file at C:\Windows ( or C:\Windows\system32 or both ) after killing the hung PSEXESVC process. Lingering process / file cause more problems.
