Re: [snmpsim-users] The application snmpsim.py died after snmpwalk

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

You seem to have inconsistent pyasn1/pysnmp versions installed. Best way to fix this is to create a Python virtualenv:

$ virtualenv venv
$ . venv/bin/activate

and then pip install the latest versions of all required packages:

$ pip install snmpsim

If you have to use old pyasn1/pysnmp, you should downgrade your snmpsim to an older version.
