SNMP不支持的安全级别

我正在尝试配置snmp守护进程，但似乎遇到了一些困难。每当我尝试运行以下命令时：

snmpget -u bootstrap -l authPriv -a MD5 -x DES -A temp_password -X temp_password remote_host 1.3.6.1.2.1.1.1.0

我得到一个错误声明：

snmpget: Unsupported security level

我一直在关注本教程：。我读了一些书，发现我在创建用户方面失败了。我把我使用的代码写在下面：

我相信我已经正确创建了用户，并通过rwuser命令提供了正确的授权。如果您能帮助我进一步调试代码，我们将不胜感激。

我想这是因为这句话：

rwuser bootstrap priv

应该是这样的:

rwuser bootstrap authPriv

如果您为用户指定了什么“安全级别”，他只能使用该“安全级别”进行身份验证

您应该使用net snmp命令行创建用户，而不是在不知道如何创建用户时手动编辑。
