Question

我从以下位置下载示例

：

http://snmplabs.com/pysnmp/examples/v3arch/twisted/agent/cmdrsp/agent-side-mib-implementations.html

并尝试运行：

snmpwalk -v2c -c public 127.0.0.1 .1.3.6

获取：

在v1中，我得到的答案是空的：

$ snmpwalk -v 1 -c public 127.0.0.1 1.3.6
End of MIB

在Debian测试中为python3-pysnmp4 4.4.6-1。

Answer 1

当您引用python3-pysnmp-4.4.6时，您的回溯来自Python 2.7。请确保您使用的pysnmp版本与示例兼容。

请注意，除非添加以下内容，否则您正在运行的example script不会响应SNMP v1查询：

 config.addVacmUser(snmpEngine, 1, 'my-area', 'noAuthNoPriv', (1, 3, 6, 5))

打电话给它。

在PySNMP中实现标量MIB对象不起作用
