My server is still on Ubuntu 20.04 and I’m ready to move to 24.04 LTS. I have full root access through a web-based KVM console and I want every current application, service and configuration file to survive the jump untouched. There are no existing backups, so the first action I expect is a secure image or snapshot of the whole system before any upgrade steps begin. Once a backup is confirmed, proceed with the standard in-place release upgrade path (20.04 → 22.04 → 24.04). Keep kernel updates in sync, handle any deprecated packages, and merge or preserve configuration files where prompts appear. After the final reboot, verify that all services start cleanly and that systemd reports no failed units. Deliverables • Verified pre-upgrade backup (image or snapshot) ...

My FileVine → S3 → Domo pipeline has been silent for roughly a month: nothing is showing up in Domo even though no one touched the FileVine or Domo settings. I need someone who can quickly trace the break, repair it, and verify that the automated reports I relied on are flowing again exactly as they did before. Here’s what matters to me: • Identify the root cause of the missing reports—whether the S3 export, the Domo connector, credentials, or schedules are at fault. • Reinstate the previous reporting schedule so the same data sets appear in Domo without manual intervention. • Confirm everything is stable by running at least one full cycle and showing the data populating live. • Provide a brief note (or short Loom) outlining what you fixed s...

I’m ready to take my student-activity website, “Falcons”, live and need a DevOps professional who can stand up a rock-solid AWS foundation around a single Ubuntu-based EC2 instance. The goal is straightforward: host the current production build, wire up the networking and security layers correctly, and make sure the whole stack is easy to maintain. Here’s what I already know I want: • AWS service in scope: EC2 (no Elastic Beanstalk or S3 for now). • Topology: one standalone instance rather than a load-balanced or auto-scaling fleet. • Operating system: Ubuntu (latest LTS preferred). What I’d like you to handle end-to-end: – Provisioning the instance, including VPC/subnet, security groups, key pairs and IAM roles that follow least-pri...

I have two virtual private servers that run several MySQL databases, yet no one can reach them externally—not even a basic telnet on port 3306. I need somebody to jump in, locate the bottleneck, and open things up so remote clients can connect with full administrative privileges. You will get SSH access to both VPS instances plus the root credentials for MySQL. I’m unsure whether any firewall (iptables/ufw/cloud panel) is blocking the port, or if the issue sits in ’s bind-address or a host-based restriction. Whatever the culprit, I just want it resolved quickly and cleanly. Acceptance criteria: • From any trusted external IP we agree on, a telnet to each server on 3306 succeeds and the MySQL client can log in using the admin user I provide. • Existing data...

I need a complete Local Area Network designed, installed, and configured for an office building.

Once everythin...

My Vicidial instance on a Linode VPS has suddenly dropped off-line. The hostname no longer resolves and I cannot reach the machine even by its IP, so I’m convinced this is a network-level problem rather than a recent configuration change—nothing has been touched for weeks. I need someone who is comfortable diving straight into a production Linode, checking DNS records, firewall rules, networking interfaces, and Vicidial/asterisk services to get everything visible on the internet again. Root SSH will be provided the moment you’re ready to start; the goal is minimal downtime and a clear explanation of what went wrong so it doesn’t repeat. Deliverable: • The server’s web and SIP services must be reachable externally at (and by direct IP). • Vicidi...

I’m running an Ubuntu droplet on DigitalOcean and simply need to power-cycle it from the control panel. I have already combed through the droplet settings menu and the usual power options but still don’t see anything labeled “power-cycle,” “reboot,” or similar. What I need from you is a quick walkthrough (screenshots, short screencast, or a concise set of steps) that shows exactly where the power-cycle action sits in the current DigitalOcean interface and how to trigger it safely. If the option has been moved, renamed, or now lives under a different tab, please point that out so I can repeat the process on other droplets later. A short session over chat or a brief annotated guide is perfect—as long as I end with a successfully rebooted droplet th...

I’m putting together a new publication and need an experienced creative partner who can guide the entire process—from shaping the concept to delivering press-ready files.

I have up to five Nectar coupon codes that I need verified in person. Your task is straightforward: visit either an Argos or a Sainsbury’s branch anywhere in the United Kingdom, head to a self-checkout, and scan each code to confirm whether it is accepted or rejected. Here is how I imagine the flow: • At the self-checkout, scan the code before payment, note the on-screen response (accepted, rejected, error, points applied, etc.), then cancel or complete the transaction as you prefer. • Capture clear photos or a short video showing the code scan and the system’s response. • Record basic details in a short report: store name, town, date/time, checkout number (if visible), and outcome for every code. Deliverables 1. Photo or video proof for each code (up ...

I’m ready to roll out Odoo Enterprise on-prem but I would like an expert beside me for the actual installation step, what I need right now is someone who knows the quirks of the Enterprise build and the usual Python/odoo user setup to make sure the first launch goes smoothly. We’ll work together over a live screen-share (or, if you prefer, a concise step-by-step document followed by a quick Q&A call). By the end of the session Odoo should be running as a service, reachable from a browser, and ready for me to dive into further configuration on my own. Key points you should be comfortable with: • Installing Odoo Enterprise • Docker That’s the scope—straightforward and focused on the installation itself. If you’ve done this a dozen times already,...

I need a physical, dedicated machine hosted in a Hyderabad-based data center that can consistently deliver very low latency to Telangana government domains. The server must run Linux and come with a static public IPv4 address; I will manage it over SSH, so no control panel is required. Network requirements are strict: stable, direct routing through a major Tier-1 Indian carrier—Sify, Airtel, Tata, or NTT are ideal—and the link should hold a low TTFB under normal load without frequent path changes. The setup is for performance-critical browsing and API calls, so rock-solid connectivity is essential. To help me verify suitability, include the following in your reply: • Exact facility name and street address in Hyderabad • Upstream ISP/carrier and routing details &...

Our customer-facing login portal suddenly stopped working right after a previous freelancer performed AWS cost-optimization tasks (Reserved Instances, auto-scaling tweaks, and some security-group changes). Users enter their credentials, hit “Sign In,” and are immediately bounced back to the login screen with no specific error—so sessions clearly aren’t being established or persisted. Here’s what I need from you: • Diagnose the exact cause of the loop (session handling, load balancer stickiness, Cognito/IAM policy, or any other AWS-related misconfiguration). • Restore normal authentication flow so clients can reach their dashboards again. • Provide a concise technical summary of the root issue and the steps you took, so we can avoid a repeat...
