RunspacePool close fail

[AndrewTsao]

Hi, I am start a long run command on remote host. After a long time , I close runspace pool, get this error, and I can't stop pssession on remote host.

requests_credssp.exceptions.AuthenticationException: Server did not response with a CredSSP token after step Step 5. Delegate Credentials - actual ''

How to run a long task with pypsrp?

How long is long? It sounds like there's some sort of timer on the session from the server and when you go to run the last command it times out.

About 120 seconds, Server is Windows Server 2012R2, Client is Win7.

from pypsrp.powershell import PowerShell, RunspacePool
from pypsrp.wsman import WSMan

if __name__ == "__main__":
    wsman = WSMan('192.168.5.31',
                    username='user',
                    password='passwd',
                    port=5985,
                    auth="credssp",
                    ssl=False)
    pool = RunspacePool(wsman)
    pool.open()
    shell = PowerShell(pool)
    shell.add_script(
        r'Start-Job -ScriptBlock { python.exe -c"import time;time.sleep(1000)" }'
    )
    shell.add_cmdlet("Out-String").add_parameter("Stream")
    output = shell.invoke()
    if shell.had_errors:
        log.error(shell.streams.error[0])
    print('\n'.join(output))

    import time
    time.sleep(120)
    pool.close()

Cool so not something that is really long so this should work, let me try it out when I get a chance to see if I can replicate it.

We are seeing a similar behavior when uploading a file to a Windows Server 2016.

@jborean93 so we found out what the issue was in our case: it is on the client side rather than on the server side. We were trying to upload the same file to multiple servers simultaneously. It was not working. We had to use throttle: 1 in Ansible to ensure the upload was done in serial. The culprit was the win_copy module.
