I have a very simple test code for testing easysnmp on a MacOS. Here is the code:

# test.py

from easysnmp import Session
session = Session(hostname='localhost', community='public', version=2)

This results in an error message as follows:

$ python test.py 
Traceback (most recent call last):
  File "/Users/me/python_utsc/test.py", line 9, in <module>
    session = Session(hostname='localhost', community='public', version=2)
  File "/Users/me/python_utsc/.venv/lib/python3.9/site-packages/easysnmp/session.py", line 280, in __init__
    self.sess_ptr = interface.session(
NameError: name 'interface' is not defined

I'm running this on a Mac v11.6 in a venv. I have installed easysnmp using the following libraries:

pip install easysnmp

pip install git+https://github.com/kamakazikamikaze/easysnmp.git

pip install git+https://github.com/nerosketch/easysnmp.git

All give the same result.

Python version:

(.venv) mbp:$ python -V
Python 3.9.7

Has anyone else run into this error? I have not found any search results on this. I'm surprised I'm not able to create a Session let alone perform any gets, sets, or walks without this error.

Thanks in advance for your input.

So the error has nothing to do with Mac OS. It was generated due to an older version of NET-SNMP which was installed:

$ snmpget --version
NET-SNMP version: 5.6.2.1

EasySNMP requires (I believe) NET-SNMP v5.7 or higher.

After running brew install net-snmp, this updated the version to the following:

snmpget --version
NET-SNMP version: 5.9.1

And now everything is working as expected.

  • Unfortunately this didn't work for me. `NET-SNMP version: 5.9.3`. I'll see if I can get brew to downgrade to `5.9.1` – Rino Bino Jan 11 '23 at 18:23
