WMI remote call in python script to create process on remote windowscomputer
 
import win32com.client
computer = "server"
strUser = "server\user_name"
strPassword ="my_password"
objSWbemLocator = win32com.client.Dispatch
("WbemScripting.SWbemLocator")
objSWbemServices = objSWbemLocator.ConnectServer(computer, "root
\cimv2",strUser,strPassword)
objCreateProc = objSWbemServices.Get("Win32_Process")
ProcessID = u"200"
objCreateProc.Create(u"cabarc n c:\\temp\\test123.PY.cab c:\\temp\
\dmj.new.log",u"c:\\temp",u' ',ProcessID )

error returned:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\path\remote.process.py", line 20, in <module>
objCreateProc.Create(u"cmd /c cabarc n c:\\temp\\test123.PY.cab c:\
\temp\\new.log",u"c:\\temp",u'',ProcessID )

what is causing this "int" error?

i have tried this with and without Unicode.
i'd like to do this without having a need to use Tim Golden's wmi
module.

Not clear which "int" error you mean, but trying to help anyway...

You need to use raw strings (or use double-backslashes). That
may or may not be the cause of your problems, but it certainly
won't help. You may also run into theoretical restrictions of
what remote WMI processes can achieve (no desktop/windowstation etc.).

To ask the obvious question: why? I'm not offended, just curious :)

As Tim says, you need to double your backslashes. You have several
places where they are not properly escaped. Alternatively, at least in
all these cases, you could use the raw strings.

But the real problem with your message would seem to be that you retyped
the material, with typos. And didn't include the entire error message.
Copy/paste are your friend. And in case you don't know how to do that
from a Windows console window, just ask. Or try Right-click on the
title bar for some ideas.

I don't have specific answers for you -- I don't currently do remote
stuff this way. But you'll get better answers if you try the above.

Re: WMI remote call in python script to create process on remotewindows computer
 
ok, cut and pasted, but changed the username/password to protect the innocent.
this is from interactive prompt.
let me know if i am still not doing the slashes correctly please.
i doubt authentication is the issue.; i can get pid information using
WQL queries.
objCreateProc.Create expects 4 strings (not objects?), right?

version info:
>>> sys.version

'2.6 (r26:66721, Oct 2 2008, 11:35:03) [MSC v.1500 32 bit (Intel)]'

>>> import win32com.client
>>> computer = "servername"
>>> strUser = "servername\\my_account"
>>> strPassword ="shh_secret"
>>> objSWbemLocator = win32com.client.Dispatch("WbemScripting.SWbemLocat or")
>>> objSWbemServices = objSWbemLocator.ConnectServer(computer, r"root\cimv2",strUser,strPassword)
>>> objCreateProc = objSWbemServices.Get("Win32_Process")
>>> ProcessID = u"200"
>>> objCreateProc.Create(u"cmd /c ping 127.0.0.1 >>c:\\temp\\finall.log",u"c:\\temp",u' ',ProcessID )

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'int' object is not callable


how can i see the method available?
>>> help(objCreateProc) just gives me "Help on instance of CDispatch in module win32com.client:"


Thanks

Looks to me like

objCreateProc.Create has an integer value.

You could add a print for that value before the call to objCreateProc.Create(). (Leave off the parentheses on the print statement)

My guess is that you've got an address there, but I have no idea how to convert that to a valid Python function pointer. Is there reasonable docs for WMI somewhere?

Invoking a method isn't as easy as that, I'm afraid. At
the risk of being boring, can I ask again why you aren't
using the wmi module, which solves these problems for
you?

In short you want to do something like this:
(simplified for testing purposes to use the local machine)

<code>
import win32com.client

wmi = win32com.client.GetObject ("winmgmts:")
win32_process = wmi.Get ("Win32_Process")
in_parameters = win32_process.Methods_ ("Create").InParameters
in_parameters.Properties_ ('CommandLine').Value = "notepad.exe"
result = win32_process.ExecMethod_ ("Create", in_parameters)

</code>

Good point, I would like just to add this:
wmi = win32com.client.GetObject ("winmgmts:\\\\username:password@host\
\root\\cimv2")
and it is perfect :)

I wasn't aware of that form of moniker construction
(ie with the username / password embedded) and on
an XP-to-2k3 link it doesn't seem to work. Is it a
Vista / 2k8 extension? Obviously, above, I was relying
on the fact that the default default namespace (as opposed
to the DEFAULT namespace ;) ) is root\cimv2.
