Network

Network - DNS zone transfer (unreachable-solution)
Clearly this is not the solution. But it seeks to be a clue.
I saw several queries in the forum, and they also confused me and made me suspect that the service was down.

Answer and clues:
1. - The service is up and running.
2. - error: unreachable, that error is fine.
3. - error: connection timed out, I did not have it but it is also good.
4. - All connection error, it took me a while and again to read and rethink dns. And one ends by consulting "man" to reread information about how a command works. And it was magical I could solve it.

My test team is an hsot with ubuntu, use [Th1b4ud : spoil tool]

Windows [Th1b4ud : spoil tool] will not work spend hours its just not changing port, use linux one but in another way in somekind

All published solutions are functional. I close.
