    I have a clean Debian 12 server ready and would like Tactical RMM, MeshCentral, and Grafana installed from scratch on this single machine. A straightforward, default-settings deployment is all I need right now—no special tweaks or custom dashboards—just a solid, working base that I can build on later. You may choose the most reliable installation method for each component (official scripts, repositoriesetc.) as long as it follows current best practices for security and updates. At the end I expect: • All three applications running and reachable on their respective ports or sub-paths • Admin credentials handed over securely • A brief note outlining the commands or playbook you used, so I can reproduce the setup if necessary If you foresee any conflicts betw...

    After uploading a fresh set of files and reorganising the entire site structure on my Amazon Lightsail instance, every URL—including the homepage—now returns a 404. Nothing else on the server was changed, so I suspect the issue sits with the web-server configuration, .htaccess rules, or the Lightsail networking/DNS settings. Here’s what I need: • Diagnose why all pages are throwing 404s. • Correct the root cause—whether that’s a VirtualHost mis-match, missing index file, wrong document root, or rewrite rule conflict. • Verify the fix by showing the site loads normally over HTTP / HTTPS. • Send me a concise summary of what you changed so I can track it for future deployments.

    My home network already runs on pfSense, but I need an experienced hand to tune it properly. The immediate priorities are: • Firewall rules – I want clear, maintainable rules that explicitly allow only the traffic I specify while leaving everything else untouched. • WireGuard VPN – configure the tunnel, keys, and routing so that remote devices can reach the LAN securely. • Traffic shaping – optimise bandwidth usage and prioritise latency-sensitive traffic. Everything should be implemented directly in the pfSense GUI, with inline comments or descriptive labels so I can understand and adjust settings later. I’ll provide current backups and remote access to the dashboard for the session. At the end I expect an updated config file plus a short chang...
