No SNMP GET response received before timeout in linux

[spot62]

This method works fine on windows, but doesn't work on linux (Ubuntu 24.04)

    async def get(self, list_of_oids, snmp_engine=SnmpEngine(), snmp_context=ContextData()):

        iterator = get_cmd(
            snmp_engine,
            CommunityData(self.community, mpModel=1),
            await UdpTransportTarget.create((self.host, self.port), timeout=self.timeout, retries=self.retries, tagList=self.tag_list),
            snmp_context,
            *self.construct_object_types(list_of_oids),
            lookupMib=False,
            lexicographicMode=False
        )

        error_indication, error_status, error_index, var_binds = await iterator

        if error_indication:
            raise RuntimeError('Got SNMP error: {0}'.format(error_indication))

        elif error_status:
            raise RuntimeError(
                "{} at {}".format(
                    error_status.prettyPrint(),
                    error_index and var_binds[int(error_index) - 1][0] or "?",
                )
            )
        else:
            logger.debug(f'[{self.host}] Got {len(var_binds)} varBinds:')
            for var_bind in var_binds:
                oid, v = var_bind
                logger.debug(f'[{self.host}] {str(oid)} = {type(v)}"{v}"')

        # snmp_engine.close_dispatcher()

        return var_binds

Returns : Got SNMP error: No SNMP response received before timeout

Why?

The snmpget with this OID also works correctly.

My environment Python 3.12.3

Package Version

---

dotenv 0.9.9
pip 24.0
pyasn1 0.6.1
pysnmp 7.1.17
python-dotenv 1.1.0

same as windows.

What might be the problem?

Thank you.

You should get started from #429.

PySNMP 5.0+ no longer uses this old repo.

Ok. Thank you.
