Online quest for enikey, how best to do it?

Question

IT education

Good afternoon, colleagues.
The question is as follows. I've been working for 3-4 months in a desk where I have already deployed a backup server on debian, fully automated it, also worked with different software like fail2ban, tell me which site can be deployed on virtualbox?
On board 10 GB of RAM.
Please leave answers by type: domain controller + proxy on frak + mail server on debian + backup.
And the like, I want to deploy a site on my virtual machines. Thanks in advance.

Answer 1

This is bullshit, trust my experience. It's like learning to have sex with a rubber woman, come on. Better pick up something immediately combat.

Answer 2

Use virtual machines to test new solutions for combat servers.
