Lightweight synchronous SNMPv1 Client implemented as a PySNMP wrapper optimized for sequential queries

---

Features

• Synchronous API for straightforward SNMPv1 GET operations
• Lightweight wrapper around PySNMP's core components
• Can be used to interface Epson printers

---

Installation

pip install py-snmp-sync

Quick Start

from py_snmp_sync import (
    SyncUdpTransportTarget, sync_get_cmd, ObjectIdentity, CommunityData
)

target = SyncUdpTransportTarget(('demo.pysnmp.com', 161))
oid = ObjectIdentity('1.3.6.1.2.1.1.1.0')

# Perform SNMP GET request
error, status, index, binds = sync_get_cmd(
    CommunityData("public", mpModel=0),
    target,
    oid
)

if not error and not status:
    for name, value in binds:
        print(f"{name.prettyPrint()} = {value.prettyPrint()}")

Usage

Basic Configuration

transport = SyncUdpTransportTarget(
    (host, 161), 
    timeout=2, 
    retries=3
)
community = CommunityData("public", mpModel=0)  # SNMPv1

• timeout: Response wait timeout (seconds)
• retries: Number of retry attempts

Alternatively, community can be a string (e.g., "public").

oid can be an ObjectIdentity() (e.g., ObjectIdentity("SNMPv2-MIB", "sysDescr", 0) or ObjectIdentity('1.3.6.1.2.1.1.1.0')), or a string (e.g., "1.3.6.1.2.1.1.1.0").

sync_get_cmd() returns a tuple similar to pysnmp get_cmd(): (error_indication, error_status, error_index, var_binds) and supports multiple OIDs per request.

Batch operations

oids = [
    ObjectIdentity('1.3.6.1.2.1.1.1.0'),
    ObjectIdentity('1.3.6.1.2.1.1.5.0')
]

with SyncUdpTransportTarget(('device-ip', 161)) as transport:
    for oid in oids:
        error, status, _, binds = sync_get_cmd(community, transport, oid)
        # Handle response
