SNMP support for Python under Windows

[WIWA]

I'm looking for SNMP support in Python. I have found pySNMP, but I'm
not sure whether this works under Windows as well. A few questions:

1) Where do I need to install the pySNMP files?
2) What do I have to do in order to be able to write somethin like:
"from pysnmp import session"

Thakns in advance for all input

Yes, it does.
A few questions:

1) Where do I need to install the pySNMP files?
Doesn't it install with distutils? If so "python setup.py --install"
or whatever it says in the README would work. Sorry, I haven't
installed it lately.

If it doesn't have instructions, put the files under the
c:/python/lib/site-packages directory.
2) What do I have to do in order to be able to write somethin like:
"from pysnmp import session"
Install, then type "from pysnmp import session".... ;-)

(If you're having troubles, please note versions and platform
next time, for Python, PySNMP, and Windows.)

Hi Peter,

Thanks for this useful information. I tried this on my Windows2000
system and it seems to work. I used distutils and modified the PATH
entry. I'll check on my Windows XP machine and will let you know if I
found any discrepancy.

Thanks again for all your effort. I have another question, but will
put that in a separate message on this discussion forum. Any help is
welcome.

I did two things, both unsuccessfull:

1) If I install the pySNMP modules under lib/site-packages and then
type sth like:
from pysnmp import session it gives the error message "ImportError: No
module named pysnmp". The same happens if I unstall pySNMP directly
under the lib directory. Installs in this context means 'copy paste'
the *.py files of the pySNMP distribution.

I misled you the first time, but have since taken another look
at the installation to see how it works. In order to import
anything from a package (roughly, a set of .py files that includes an
__init__.py file), you need to put those files in a directory
which is named for the package (e.g. pysnmp in this case) _and_
which is available in sys.path. (Do "import sys" and "sys.path"
to see the list. You probably have lib/site-packages in that
list, so just put all the PySNMP files under it in a folder called
pysnmp.)

- Do I need to explicitly mention in my script where pySNMP is
installed?

Not if it's in a folder called pysnmp that is itself in one of the
sys.path folders, or under the current folder.

2) I installed distutils 1.0.2 for Windows and it installed into the
Python directory. So ar so good, I think...

Distutils is included in Python so you probably didn't need to do
that, and maybe shouldn't have. I'm not sure whether that will have
broken the standard distutils. It's repairable if it did. On my
Python 2.2.1 setup here, the standard distutils is v1.0.3.

I go to DOS prompt and go to the directory where disutils is installed
and type in python setup.py install, but DOS replies:
'Python is not recognized as an internal or external command, program
or batchfile".

Now that's a different problem. You need python.exe to be findable
from the DOS PATH. The simplest approach might be to check the FAQ
entry at http://www.python.org/cgi-bin/faqw.p...=faq08.018.htp

As a test of the pysnmp installation, without having to change PATH
at all, change to the Python directory ("cd \python" or whatever)
and run the interactive interpreter ("python") and just type
"import pysnmp" to see if it works.

System coordinates are Windows XP. Python version is 2.2.2 and pySNMP
is version 3.0.0.

Should all be no problem, although I suspect instructions in that
FAQ entry may be a little light on XP advice. Let us know if you
see any area that could be improved so others can benefit from this
exchange...
