【问题描述】:
我使用 pysnmp 发送 SNMP 陷阱,代码如下 (trap.py) source,
注意:X.X.X.X是我电脑的公网ip地址
from pysnmp.hlapi import *
from pysnmp import debug
hostname = 'X.X.X.X' ##public IP address of receiver
debug.setLogger(debug.Debug('msgproc'))
next(sendNotification(SnmpEngine(),
CommunityData('public'),
UdpTransportTarget((hostname, 162)),
ContextData(),
'trap',
# sequence of custom OID-value pairs
[ObjectType(ObjectIdentity('1.3.6.1.2.1.1.1.0'), OctetString('my string')),
ObjectType(ObjectIdentity('1.3.6.1.2.1.1.3.0'), Integer32(42))]))
我正在使用带有此代码的 pysnmp 接收它 (receiver.py) source
from pysnmp.entity import engine, config
from pysnmp.carrier.asyncore.dgram import udp
from pysnmp.entity.rfc3413 import ntfrcv
# Create SNMP engine with autogenernated engineID and pre-bound
# to socket transport dispatcher
snmpEngine = engine.SnmpEngine()
# Transport setup
# UDP over IPv4, first listening interface/port
config.addTransport(
snmpEngine,
udp.domainName + (1,),
udp.UdpTransport().openServerMode(('X.X.X.X', 162))
)
# SNMPv1/2c setup
# SecurityName <-> CommunityName mapping
config.addV1System(snmpEngine, 'my-area', 'public')
# Callback function for receiving notifications
# noinspection PyUnusedLocal,PyUnusedLocal,PyUnusedLocal
def cbFun(snmpEngine, stateReference, contextEngineId, contextName,
varBinds, cbCtx):
print('Notification from ContextEngineId "%s", ContextName "%s"' % (contextEngineId.prettyPrint(),
contextName.prettyPrint()))
for name, val in varBinds:
print('%s = %s' % (name.prettyPrint(), val.prettyPrint()))
# Register SNMP Application at the SNMP engine
ntfrcv.NotificationReceiver(snmpEngine, cbFun)
snmpEngine.transportDispatcher.jobStarted(1) # this job would never finish
# Run I/O dispatcher which would receive queries and send confirmations
try:
snmpEngine.transportDispatcher.runDispatcher()
except:
snmpEngine.transportDispatcher.closeDispatcher()
raise
在receiver.py中,我得到一个错误
pysnmp.carrier.error.CarrierError: bind() for ('X.X.X.X', 162) 失败:[WinError 10049] 请求的地址在其 上下文
我希望能够在非本地发送 SNMP 陷阱。所以我正在用我的公共 IP 地址测试 test.py。一切都在本地工作(如果我使用 127.0.0.1)但不能使用公共 IP 地址。我应该安装其他 SNMP 软件来收听 trap.py 吗?
