win32serviceutil won't start

[Nikola Skoric]

I have a very simple win32serviceutil script:
import win32serviceutil, time

win32serviceutil.StartService("burek", "localhost")

time.sleep(10)

exit()

It successfuly imports win32serviceutil, and chokes on StartService:
Traceback (most recent call last):
File "foobar.py", line 3, in ?
win32serviceutil.StartService("burek", "localhost")
File "C:\Python24\Lib\site-packages\win32\lib\win32serviceutil.py", line
399, in StartService
hs = SmartOpenService(hscm, serviceName, win32service.SERVICE_ALL_ACCESS)
File "C:\Python24\Lib\site-packages\win32\lib\win32serviceutil.py", line
76, in SmartOpenService
return win32service.OpenService(hscm, name, access)
pywintypes.error: (1060, 'OpenService', 'The specified service does not
exist as an installed service.')

What does that mean?

Looks like Microsoft thinks you mis-spelled it.

I would check and see if that service is installed on your PC. You can
go to Start --> Run and type services.msc

Scroll through there and see if your service is listed. You might
check to see if you can enable/disable it via that console as well.

Seems like I misunderstood Windows services (I'm porting UNIX daemon
to Windows so I'm thinking in UNIX terms). I didn't know I have to
_install_ a service before I _start_ it. How do I install a service?

Read chapter 18 of Python Programming on Win32 by Mark Hammond & Andy
Robinson. There is a paragraph on "Installing, Debugging and Running a
Python Service" starting on page 350. In short: use PythonService.exe
from the PyWin32 package. Then google for "smallestpythonservice".

Sorry I didn't reply sooner. If you're creating a service based on a
Python file, check out the following links in addition to the book

That should get you started. Hope it helps!

Huh. Thank you guys a lot. I took a glance (albeit a rather long one)
and decided that my users will have to install cygwin if they want to
use my script. Service handling is just a bit to complicated (after
creating UNIX daemon with 2 consecutive forks), and I'm not going to
be paid for this :-D

Yeah...a lot of things on Windows is just too complicated for its own
good. Every now and again you'll stumble across something that's
pretty elegant though.
