    My single-domain server on Virtualmin is about to lose its SSL and I can’t switch to any outside certificate provider, so I need a fresh Let’s Encrypt SSL generated and installed right away. I’d like you to: • Trigger a clean Let’s Encrypt renewal inside Virtualmin • Apply the new certificate to both the domain and Webmin/Usermin services so every port stays secure • Verify that the site, mail, and control panel all load without browser warnings You’ll have /Virtualmin access via Anydesk ONLY. Once you finish, I want to see the green padlock in every major browser and the certificate details reflecting the new expiry date. I’m ready to move immediately—please let me know how quickly you can jump in. $20 is the MAX budget.

    We are looking for an experienced DNS and domain reputation specialist to help resolve an ongoing production issue affecting users on certain mobile networks (specifically T-Mobile). The specific error users see is: DNS_PROBE_FINISHED_NXDOMAIN Our platform is hosted on AWS (Route 53 + ALB / CloudFront). DNS is correctly configured and resolves properly on most networks (Google DNS, Quad9, etc.). Our domain reputation has already been reviewed and corrected by major security providers. However, users on T-Mobile are still experiencing DNS-based blocking or resolution issues. This appears to be related to carrier-level DNS filtering or residual reputation/security classification behavior — not core infrastructure misconfiguration. ⸻ Scope of Work • Diagnose carrier-level DNS...

You’re free to structure the project with popular Go web frameworks such as Gin, Echo, or Fiber, as long as the final build remains lightweight and easy to maintain. I will supply server access and a blank MySQL instance; you take it from there—designing the schema, wiring up the handlers, and exposing routes that follow REST principles. Code quality, straightforward error handling, and secure interaction with the database are priorities.

    Ubuntu Airtel SIP Initial Setup

    Vérifié

    I need a proven Airtel Black SIP configuration running on my Ubuntu machine and handled through Linphone. The goal is a clean, documented initial setup—no trial-and-error learning on my system, please. If you have already registered an Airtel SIP trunk on Linux, you’ll know the exact registrar format, the unusual port mapping Airtel uses, and the little tweaks that keep audio flowing both ways behind NAT. Here’s the workflow I’m expecting: • Install or verify the latest Linphone and any required dependencies on my Ubuntu box. • Register the Airtel Black SIP account, applying the correct proxy, authentication string, and codec priorities. • Prove the setup with at least one inbound and one outbound call (I can join you on a test call). •...

    I have completed a desktop application with Lovble IA and pushed the code to a GitHub repository. Now I need it running smoothly on my own Linux server. Your job is to pull the repo, set up whatever build or runtime environment Lovble IA requires, resolve any package or dependency issues, and make sure the executable starts up reliably (ideally as a service so it can restart after reboots). The repository is ready for cloning; you will receive access as soon as we start. I expect the finished application to launch without errors from the server’s command line or through an appropriate display manager, and I’d like brief notes on every step you take so I can replicate or update the deployment later. Deliverables • Working installation of the Lovble IA desktop app on my Li...
