Re: [snmpsim-users] Unable to initialize variation modules

[Ilya E. <il...@gl...>]

Hi Andrew,

So far I can't reproduce your issue with the same Python and snmpsim 
versions. Could it be that you have remnants of some development version 
of snmpsim still installed on your system? If so you should reinstall 
vanilla 0.2.3:

   https://sourceforge.net/projects/snmpsim/files/snmpsim/0.2.3/

or, if you need the latest features:

   http://snmpsim.sourceforge.net/changes.html

you may consider trying the latest development version:

   https://sourceforge.net/projects/snmpsim/files/snmpsim/0.2.4/

In either case make sure variation module directory 
(/usr/lib/python2.4/site-packages/snmpsim-0.2.3-py2.4.egg/snmpsim/variation) 
gets cleaned up and updated so that no incompatible modules persist there.

Another thing is that your --variation-module-options syntax is 
incorrect. The right one is:

   --variation-module-options=writecache:dbA:file:./datasets.db

however you might not really need the dbA alias so I'd use just:

   --variation-module-options=writecache:file:./datasets.db

Here I suppose that module loading failure gets resolved by snmpsim upgrade.

Finally, the --v2c-arch option is incompatible with any of --v3-* 
options. You can read more on the --v2c-arch option intended use and 
features here:

   http://snmpsim.sourceforge.net/simulator-tips.html

and here:

   http://snmpsim.sourceforge.net/transport-based-variation.html

Let me know in case of further issues,
ilya
