SNMP 不受支持的安全级别

Question

我正在尝试配置我的 snmp 守护程序，但我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

我收到一条错误消息：

snmpget: Unsupported security level

我一直在关注本教程：https://www.digitalocean.com/community/tutorials/how-to-install-and-configure-an-snmp-daemon-and-client-on-ubuntu- 14-04。我读了一些书，发现我在创建用户方面失败了。我把我用过的代码放在下面：

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。任何进一步调试我的代码的帮助将不胜感激。

我想是因为这条线：

rwuser bootstrap priv

应该是这样的：

rwuser bootstrap authPriv

如果你给用户什么“安全级别”，他只能用那个“安全级别”来认证
