Question

System administration

Why do some system administrators reject panels like Webmin, Ajenti, ISPConfig?
In my opinion, there is such a trend.
And pretty durable.
Or am I wrong?
Are there competent people who use these (or similar) software?
Why am I asking this question?
I want to use any of the above solutions, but I have doubts.
Interested in whether there are "adequate" arguments in favor of these panels?

Answer 1

Because the admin doesn't need them.
All the same, you will have to connect a little via ssh.
So what's the point?
And here to the user without the panel in any way.

No

Answer 3

Because they are complete shit, well, really shit, especially obviously with different migrations and updates, if you want a panel, take it forever for cheap or a splash, or a panel from a provider

Answer 4

Hands are not convenient, but everything is transparent and understandable, unlike panels

Answer 5

It's all just if you want to use it - use it. If you want a console, use the console.
