About me
Hi, I’m Jingchen. I help beginners set up safer Ubuntu cloud servers.
I can help with SSH key login, non-root sudo users, disabling root SSH login, disabling password login, UFW firewall rules, and private WireGuard admin VPN setup.
I recently built and tested this setup on a DigitalOcean Ubuntu 24.04 server, including Windows client configuration and connection testing.
I do not provide public proxy, bypass, anonymity, or abuse-related services.
