SNMP Library for Python
-----------------------

[![PyPI](https://img.shields.io/pypi/v/pysnmp-lextudio.svg)](https://pypi.python.org/pypi/pysnmp-lextudio)
[![PyPI Downloads](https://img.shields.io/pypi/dd/pysnmp-lextudio)](https://pypi.python.org/pypi/pysnmp-lextudio/)
[![Python Versions](https://img.shields.io/pypi/pyversions/pysnmp-lextudio.svg)](https://pypi.python.org/pypi/pysnmp-lextudio/)
[![GitHub license](https://img.shields.io/badge/license-BSD-blue.svg)](https://raw.githubusercontent.com/lextudio/pysnmp/master/LICENSE.rst)

This is a pure-Python, open source and free implementation of v1/v2c/v3
SNMP engine distributed under 2-clause [BSD license](https://www.pysnmp.com/pysnmp/license.html).

The PySNMP project was initially sponsored by a [PSF](http://www.python.org/psf/) grant.
Thank you!

This version is a fork of Ilya Etingof's project [etingof/pysnmp](https://github.com/etingof/pysnmp). Ilya sadly passed away on 10-Aug-2022. Announcement [here](https://lists.openstack.org/pipermail/openstack-discuss/2022-August/030062.html).  His work is still of great use to the Python community and he will be missed.

Features
--------

* Complete SNMPv1/v2c and SNMPv3 support
* SMI framework for resolving MIB information and implementing SMI
  Managed Objects
* Complete SNMP entity implementation
* USM Extended Security Options support (3DES, 192/256-bit AES encryption)
* Extensible network transports framework (UDP/IPv4, UDP/IPv6)
* Asynchronous socket-based IO API support
* [Asyncio](https://docs.python.org/3/library/asyncio.html) integration
* [PySMI](https://www.pysnmp.com/pysmi/) integration for dynamic MIB compilation
* Built-in instrumentation exposing protocol engine operations
* Python eggs and py2exe friendly
* 100% Python, works with Python 3.7+
* MT-safe (if SnmpEngine is thread-local)

Features, specific to SNMPv3 model include:

* USM authentication (MD5/SHA-1/SHA-2) and privacy (DES/AES) protocols (RFC3414, RFC7860)
* View-based access control to use with any SNMP model (RFC3415)
* Built-in SNMP proxy PDU converter for building multi-lingual
  SNMP entities (RFC2576)
* Remote SNMP engine configuration
* Optional SNMP engine discovery
* Shipped with standard SNMP applications (RC3413)


Download & Install
------------------

The PySNMP software is freely available for download from [PyPI](https://pypi.python.org/pypi/pysnmp-lextudio)
and [GitHub](https://github.com/lextudio/pysnmp.git).

Just run:

```bash
$ pip install pysnmp-lextudio
```

To download and install PySNMP along with its dependencies:

<!-- Need to find an alternate location for the links to pysnmp.com -->
* [PyASN1](https://pyasn1.readthedocs.io)
* [PySMI](https://www.pysnmp.com/pysmi/) (required for MIB services only)
* Optional [pysnmpcrypto](https://github.com/etingof/pysnmpcrypto) package
  whenever strong SNMPv3 encryption is desired

Besides the library, command-line [SNMP utilities](https://github.com/lextudio/snmpclitools)
written in pure-Python could be installed via:

```bash
$ pip install snmpclitools-lextudio
```

and used in the very similar manner as conventional Net-SNMP tools:

```bash
$ snmpget.py -v3 -l authPriv -u usr-md5-des -A authkey1 -X privkey1 demo.pysnmp.com sysDescr.0
SNMPv2-MIB::sysDescr.0 = STRING: Linux zeus 4.8.6.5-smp #2 SMP Sun Nov 13 14:58:11 CDT 2016 i686
```

Examples
--------

PySNMP is designed in a layered fashion. Top-level and easiest to use API is known as
*hlapi*. Here's a quick example on how to SNMP GET:

```python
import asyncio
from pysnmp.hlapi.asyncio.slim import Slim
from pysnmp.smi.rfc1902 import ObjectIdentity, ObjectType

async def run():
    slim = Slim(1)
    errorIndication, errorStatus, errorIndex, varBinds = await slim.get(
        'public',
        'demo.pysnmp.com',
        161,
        ObjectType(ObjectIdentity("SNMPv2-MIB", "sysDescr", 0)),
    )

    if errorIndication:
        print(errorIndication)
    elif errorStatus:
        print(
            "{} at {}".format(
                errorStatus.prettyPrint(),
                errorIndex and varBinds[int(errorIndex) - 1][0] or "?",
            )
        )
    else:
        for varBind in varBinds:
            print(" = ".join([x.prettyPrint() for x in varBind]))

    slim.close()


asyncio.run(run())
```

This is how to send SNMP TRAP:

```python
import asyncio
from pysnmp.hlapi.asyncio import *

async def run():
    snmpEngine = SnmpEngine()
    errorIndication, errorStatus, errorIndex, varBinds = await sendNotification(
        snmpEngine,
        CommunityData('public', mpModel=0),
        UdpTransportTarget(('demo.pysnmp.com', 162)),
        ContextData(),
        "trap",
        NotificationType(ObjectIdentity("1.3.6.1.6.3.1.1.5.2")).addVarBinds(
            ("1.3.6.1.6.3.1.1.4.3.0", "1.3.6.1.4.1.20408.4.1.1.2"),
            ("1.3.6.1.2.1.1.1.0", OctetString("my system")),
        ),
    )

    if errorIndication:
        print(errorIndication)

    snmpEngine.transportDispatcher.closeDispatcher()

asyncio.run(run())
```

> We maintain publicly available SNMP Agent and TRAP sink at
> [demo.pysnmp.com](https://www.pysnmp.com/snmpsim/public-snmp-agent-simulator.html). You are
> welcome to use it while experimenting with whatever SNMP software you deal with.

```bash
$ python3 examples/hlapi/asyncio/manager/cmdgen/usm-sha-aes128.py
SNMPv2-MIB::sysDescr.0 = SunOS zeus.pysnmp.com 4.1.3_U1 1 sun4m
$
$ python3 examples//hlapi/asyncore/sync/agent/ntforg/v3-inform.py
SNMPv2-MIB::sysUpTime.0 = 0
SNMPv2-MIB::snmpTrapOID.0 = SNMPv2-MIB::warmStart
SNMPv2-MIB::sysName.0 = system name
```

Other than that, PySNMP is capable to automatically fetch and use required MIBs from HTTP, FTP sites
or local directories. You could configure any MIB source available to you (including
[this one](https://github.com/lextudio/mibs.snmplabs.com/tree/master/asn1)) for that purpose.

at pysnmp web site.
