我正在尝试在链接本地地址FE80::1:1%enp0s8
上向代理进行SNMP查询。这是代码:
#!/usr/bin/python3
from pysnmp.hlapi import *
USER_KEY='manager1'
AUTH_PROT=usmHMACMD5AuthProtocol
PRIV_PROT=usmAesCfb256Protocol
userData = UsmUserData('manager', authKey=USER_KEY,
privKey=USER_KEY,
authProtocol=AUTH_PROT,
privProtocol=PRIV_PROT)
target=Udp6TransportTarget(('FE80::1:1%enp0s8',161))
g = getCmd(SnmpEngine(),
userData,
target,
ContextData(),
ObjectType(ObjectIdentity('SNMPv2-MIB','sysUpTime',0)))
print(next(g))
其中enp0s8
是我找到代理的界面。但是,当我使用它时,我收到此错误消息:
Traceback (most recent call last):
File "get-SNMP-var.py", line 21, in <module>
print(next(g))

value = self.prettyIn(value)

OSError: illegal IP address string passed to inet_pton
当我没有为此链接本地地址指定接口时,我会抽出时间。使用snmpget
实用程序指定范围有效。
我的问题是:如何使用Udp6TransportTarget
?
