我的机架中运行着 2 台 UPS NUT 服务器。1 台在 TrueNAS SCALE 上运行，另一台在 Synology DS918+ 上运行。还有一个 NUT 客户端在 ubuntu 服务器上运行。
NUT 客户端不断抱怨：
Broadcast message from nut@nuc13 (somewhere) (Sat Jan 27 16:16:52 2024):
UPS [email protected] is unavailable
Broadcast message from nut@nuc13 (somewhere) (Sat Jan 27 16:16:52 2024):
UPS [email protected] is unavailable
有人能帮我修复它吗？
以下是删除注释后的 upsmon.conf 内容：

使用 telnet 似乎可以工作。以下是从 ubuntu 服务器连接到 DS918+ 的示例（基于 IP 的身份验证。无需登录）：

并且从 ubuntu 连接到 TrueNAS 也没有问题：

愚蠢的我。
我已经解决了这个问题。upsmon.conf 需要从 nut 服务器列出的 ups 实体的准确名称，即 upsmon.conf 的第一行应该是
MONITOR [email protected] 1 [username] [password] secondary
MONITOR [email protected] 0 [username] [password] secondary
