FAQ
What access do you need?
I need SSH access to your server (root or sudo user). Your server must be reachable via IP or domain.
Is this safe for production servers?
Yes. All changes are applied carefully and tested to ensure your server remains stable and functional. No risky or destructive actions are performed.
Will my server go offline during the setup?
No, your server will remain online. In rare cases, a short restart may be required, but I will inform you in advance.
Do you support all Linux distributions?
I support Ubuntu, Debian, and most common Linux distributions. Contact me first if you are unsure.
Can you fix an already compromised server?
Yes, but please contact me before ordering. Recovery depends on the level of compromise.
Do you offer custom security configurations?
Yes. If you need advanced configurations or custom setups, please contact me before ordering for custom configurations.
