Im trying to reproduce the following batch file but on command-line oneliner. Id like to be able to use this client in python scripts and to identify if a connection is made I need to be able to retrieve the error codes. I am calling the application via subprocess Any help would be appreciated

BATCH FILE CODE

ECHO OFF START /WAIT rdp.exe /v:192.168.1.122 /u:xpuser /p:xpuser /batch ECHO %ERRORLEVEL%

I have tried the below commands along with many variations but cant get what is expected. Information on the executable can be found here

EXAMPLE

c:\Python27>start /WAIT rdp.exe /v:192.168.1.122 /u:xpuser /p:xpuser /log /batch | ECHO %ERRORLEVEL% c:\Python27>start rdp.exe /v:192.168.1.122 /u:xpuser /p:xpuser /batch || ECHO %ERRORLEVEL%

SNIPPET OF PYTHON CODE

 try: cmdrdp = "rdp.exe /v:%s /u:%s /p:%s /log /batch" % (server, username, password) subprocess.check_output(cmdrdp) except CalledProcessError as e: print(e.returncode) else: print "Connected to: %s %s %s" % (server, username, password)

If you pass a single string to subprocess.check_output, it's interpeted as the literal file name, if you want it to work you need to pass the shell=True argument.

However, the recommended way of using the subprocess family of functions is with a list of strings as argument:

subprocess.check_output(["rdp.exe", "/v:" + server, "/u:" + username, "/p:" + password, "/log", "/batch"])
