HI, guy,

Can you tell me how the "hostid" command work? or how can I control my "hostid"?

Why my output from "hostid " switch around "0a799228", "0a799a28", "0a799328" randomly?

Here are lists of my "hostid" information, if any other information needed, please just mail me directly.

Hope to get you reply soon, thanks.
