The first part: Install snmp program and service.

There are two ways to install snmp support in Ubuntu. The first is to install it directly through apt-get. The second is to download the source code net-snmp-5.7.3.tar.gz from the netsnmp official website, and compile and install it.

Regarding the second method, I have checked the methods on the Internet. Unfortunately, I have not succeeded in the end, so I recommend the first method here.

The first step is to install snmpd, snmp, and snmp-mibs-downloader

snmpd is a process that monitors the snmp service, binds to a certain port, waits for the SNMP request from the requester, processes it, and returns information to the requester.

snmp is the snmp command set of a requester.

snmp-mibs-downloader

The following is the installation command:

～$sudo apt-get install snmp

～$sudo apt-get install snmpd

～$sudo apt-get install snmp-mibs-download

The second step is to start the snmpd service

～$sudo service snmpd restart

Finally, test whether the following is successful

～$snmpwalk -v 2c -c public localhost

If the data is returned correctly, it means that the installed snmp can be used normally.

The second part: install the python programming package corresponding to netsnmp.

Here is mainly to install netsnmp-py, https://pypi.org/project/netsnmp-py/.

First, install the corresponding dependent libraries.

～$sudo apt-get install libsnmp30 libsnmp-dev libczmq-dev

The name of libsnmp-dev libczmq-dev cannot be wrong, otherwise it will not be found.

Second, install pyzmq, pyczmq. http://pyzmq.readthedocs.io/en/latest/index.html

～$sudo pip install pyczmq

Next, install netsnmp-py and you are done.

～$sudo pip install netsnmp-py

Finally, it is to test whether the netsnmp-py function is available in python in the program.

In netsnmp-py, a SNMPSession class is provided, which provides three basic functions get/getnext/walk.

For details, please refer to: sample in usr/local/lib/python3.6/dist-packages/netsnmp/init.py.

example:

～$python

Python 3.6.5 (default, Apr 1 2018, 05:46:30) [GCC 7.3.0] on linux Type "help", "copyright", "credits" or "license" for more information. >>> import netsnmp >>> with netsnmp.SNMPSession('localhost', 'public') as ss: ... ss.get(['.1.3.6.1.2.1.1.1.0', '.1.3.6.1.2.1.1.3.0']) ... [('.1.3.6.1.2.1.1.1.0', 'STRING', '"Linux laosierLinux 4.15.0-22-generic #24-Ubuntu SMP Wed May 16 12:15:17 UTC 2018 x86_64"'), ('.1.3.6.1.2.1.1.3.0', 'Timeticks', '0:3:13:31.57')] >>>

If the above information is returned, haha, I wish you success.
