超时前未收到 SNMP 响应 - 使用非常基础的示例示例
No SNMP response received before timeout-with very basics sample examples
我是 pysnmp 的新手。在阅读 snmplabs.com 的文档时，我尝试了 get_command 的代码，但我得到的输出是在超时
之前没有收到 SNMP 响应
正如在对几个类似问题的回答中提到的，我尝试在我的代码开头添加下面提到的内容。
from pysnmp import debug
debug.setLogger(debug.Debug('io', 'msgproc', 'secmod'))
完整代码如下图
from pysnmp.hlapi import *
from pysnmp import debug
debug.setLogger(debug.Debug('io', 'msgproc', 'secmod'))
def getFunc(OID):
errorIndication, errorStatus, errorIndex, varBinds = next(
getCmd(SnmpEngine(),
CommunityData('public', mpModel=0),
UdpTransportTarget(('demo.snmplabs.com', 161)),
ContextData(),
ObjectType(ObjectIdentity('SNMPv2-MIB', OID, 0)))
)
if errorIndication:
print(errorIndication)
elif errorStatus:
print('%s at %s' % (errorStatus.prettyPrint(),
errorIndex and varBinds[int(errorIndex) - 1][0] or '?'))
else:
for varBind in varBinds:
print(' = '.join([x.prettyPrint() for x in varBind]))
if __name__ == "__main__":
getFunc('sysName')
输出日志如下图

我是 pysnmp 的新手。在阅读 snmplabs.com 的文档时，我尝试了 get_command 的代码，但我得到的输出是在超时
之前没有收到 SNMP 响应正如在对几个类似问题的回答中提到的，我尝试在我的代码开头添加下面提到的内容。
from pysnmp import debug
debug.setLogger(debug.Debug('io', 'msgproc', 'secmod'))
完整代码如下图
from pysnmp.hlapi import *
from pysnmp import debug
debug.setLogger(debug.Debug('io', 'msgproc', 'secmod'))
def getFunc(OID):
errorIndication, errorStatus, errorIndex, varBinds = next(
getCmd(SnmpEngine(),
CommunityData('public', mpModel=0),
UdpTransportTarget(('demo.snmplabs.com', 161)),
ContextData(),
ObjectType(ObjectIdentity('SNMPv2-MIB', OID, 0)))
)
if errorIndication:
print(errorIndication)
elif errorStatus:
print('%s at %s' % (errorStatus.prettyPrint(),
errorIndex and varBinds[int(errorIndex) - 1][0] or '?'))
else:
for varBind in varBinds:
print(' = '.join([x.prettyPrint() for x in varBind]))
if __name__ == "__main__":
getFunc('sysName')
输出日志如下图
