Question

我正在尝试使用以下代码执行简单的SNMP操作。请帮我弄清楚错误。

    from pysnmp.entity.rfc3413.oneliner import cmdgen

    cmdGen = cmdgen.CommandGenerator()

    errorIndication, errorStatus, errorIndex, varBinds = cmdGen.getCmd(
        cmdgen.CommunityData('public'),
        cmdgen.UdpTransportTarget(('demo.snmplabs.com', 161)),
        cmdgen.MibVariable('SNMPv2-MIB', 'sysName', 0),
    )

    # Check for errors and print out results
    if errorIndication:
        print(errorIndication)
    elif errorStatus:
        print(errorStatus)
    else:
        for name, val in varBinds:
            print('%s = %s' % (name.prettyPrint(), val.prettyPrint()))

上面的代码给出了以下错误：

Traceback (most recent call last):

    from pysnmp.entity.rfc3413.oneliner import cmdgen
  File "/usr/lib/python2.6/site-packages/pysnmp/entity/rfc3413/oneliner/cmdgen.py", line 1, in <module>

Answer 1

有可能是你的系统pyasn1 pysnmp包与版本不兼容。我建议将pyasn1和pysnmp软件包（最新的软件包）放入你的$ HOME并设置$ PYTHONPATH指向每个软件包。

没有名为compat.octets的模块
