Script Installation

Note

pip must be installed prior to the installation of the bsnmp script.

Put the script file bsnmp.py into a location on the DIR host where the DIR can execute programs in. We propose to use /opt/bacula/scripts

Make the file executable by the Bacula DIR user account, usually bacula:

chown bacula. /opt/bacula/scripts/bsnmp.py
chmod u+x /opt/bacula/scripts/bsnmp.py

Ensure python3 is available: python3 --version should not fail.

Ensure the needed dependencies are installed. This can be somewhat difficult and may depend on distribution and python installation. In typical cases, with package based installations, but you may need to install the modules using pip:

# python3
Python 3.9.21 (main, Feb 10 2025, 00:00:00)
[GCC 11.5.0 20240719 (Red Hat 11.5.0-5)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import argparse

ModuleNotFoundError: No module named 'pyasn1'
>>> import asyncio
>>> import pysnmp

The bsnmp script uses the SNMP library for Python (pysnmplib).

The Python modules required can be installed using pip:
