Ubuntu Jobs

I need a complete, beginner-friendly learning package that introduces cybersecurity fundamentals through the lens of Kali Linux. The core of the course should revolve around ethical hacking concepts while also giving students a solid grounding in day-to-day security operations and other “basic stuff”—password hygiene, simple hardening steps, and the mindset behind defensive as well as offensive techniques. If you spot an area that would benefit newcomers, feel free to adapt; I want the material to grow with the learner’s needs. Here is what I expect: • A clear, progressive syllabus that spans theory and hands-on work inside Kali Linux. • Short, engaging video tutorials (screen-capture with voice-over is fine) that demonstrate each skill step by step&m...

Project Overview We run a Laravel-based web application currently stuck on Laravel 7.x. We're ready to bring the whole stack up to date framework, PHP, packages, and the servers it runs on. We're looking for an experienced Laravel developer to handle the upgrade end-to-end, validate it on staging, and help us deploy to production safely. Scope of Work: Framework upgrade — Laravel 7.x up to the latest stable release (12.x / 13.x). You're welcome to use Laravel Shift as a starting point, but we expect hands-on work to finish the job cleanly. PHP upgrade — bump to PHP 8.4. Package migration — several dependencies are outdated, abandoned, or incompatible. Sentry is the most notable one that will need replacing/updating. We'll share the full so you can a...

This is not a commercial venture, just a hobby, so only a pensioner's funds are available My Discord server is running on Windows and, at the moment, it has no version of Python installed. I need someone who can come in, install Python 3.6 or newer alongside a working build of FFmpeg, and then walk me through everything that follows with clear screenshots and captions. What I expect after the installs are complete: • A brand-new Bot Application created in the Discord Developer Portal • The exact steps (with screenshots) that show how you pulled the Bot Token • A simple-yet-repeatable local development environment for the bot’s code (VS Code, PyCharm or even bare-bones IDLE is fine—whatever you’re most comfortable demonstrating) • Sample Py...

I’m moving my corporate website from a Droplet on DigitalOcean to a new VPS at Contabo and want the transition handled end-to-end. The application is entirely custom code written in Node.js with Express, so experience deploying and tuning this stack on Ubuntu-based servers is essential. Scope of work • Provision and harden the Contabo VPS (firewall, SSH keys, fail2ban, basic monitoring). • Copy all application files, environment variables, and assets from the current server. • Migrate the MongoDB and Redis data stores (both run locally on the box) without loss or downtime. • Recreate the PM2 process manager setup, configure Nginx as reverse proxy with SSL (Let’s Encrypt), and ensure logs rotate properly. • Update DNS, verify SSL, and perfor...

My Ubuntu laptop needs a clean, reproducible setup that lets me tap directly into AI coding assistants—specifically OpenAI Codex or Anthropic Claude—to accelerate day-to-day Python software development. Here’s what I expect once the job is done: • A fully configured local environment (Ubuntu 22.04 LTS) with all required SDKs, CLI tools, API keys, and network settings so I can call Codex or Claude from the terminal, VS Code, and Jupyter. • Smooth workflows for code generation, optimisation, and debugging assistance integrated into VS Code (or another lightweight IDE if you prefer) with examples that prove each capability works end-to-end on a sample Python project. • Clear, step-by-step documentation and a single bootstrap script or Ansible/DevOps r...

My current Python automation script runs, but the results are wrong—so the core problem is logical errors rather than anything that fails at compile time. I need an experienced Python developer to trace the faulty logic, correct it, and then put the working script into production. You will start by reviewing the code and any helper modules, replicate the bug I am seeing, and explain why the output is off. Once the logic is patched, I want the script fully tested under the same data sets that exposed the issue, plus a few edge-case inputs to ensure robustness. When the fixes are confirmed, the final step is deployment to the live environment. The project sits on a small Ubuntu VPS with Python 3.10, virtualenv and Git already in place, so you can push the clean code straight to the s...

I have a Hetzner server standing by and a bundle of configuration files that are already final—no tweaks, edits, or refactoring required. What I need is a smooth, verifiable hand-off from my local machine to the correct paths on the server. Here’s the flow I’m after: • Establish an SSH session (key-based access is ready). • Transfer each configuration file to its proper directory, preserving ownership and permissions. • Reload or restart any affected services so the new configs take effect immediately. • Confirm there are no syntax errors or failed services once the reload is complete. The files cover the usual suspects—think web, database, or application layers—though again, they’re all prepared and tested; this job is stri...

My mobile app and its companion website are feature-complete and publicly available, yet the service keeps dropping because of recurring server downtime. Getting the servers back to stable, continuous operation is my single most urgent goal. While you diagnose and resolve the root cause, you may also notice a few minor bugs on the app and site; feel free to flag them so we can tackle those once uptime is restored. I host everything on a single VPS with typical LAMP-style services and a REST API that the app calls. During an outage users receive generic 5xx errors, forcing me to reboot the instance to recover. I need a clean, permanent fix rather than another temporary restart. Please send a detailed project proposal that explains • how you will isolate the source of the downtime, ...

I already have a working Python strategy that uses Angel One SmartAPI and pushes trade-execution alerts to a Telegram bot. All I need now is a clean deployment on my Windows-based VPS, plus a quick round of live testing to confirm everything fires correctly. Environment • VPS: Windows (fresh instance, RDP access ready) • Code: Fully written, installs with , uses SmartAPI and python-telegram-bot. • Budget: ₹3-5k; I’m happy to split it into two milestones—deployment and successful test run. What I’m looking for 1. Remote setup of Python, required libraries, and SmartAPI credentials on the VPS. 2. Configuration of the Telegram bot so it notifies me on every trade execution. 3. Guidance on credential storage and security; I’m not sure if I&r...

I need end-to-end TLS enforced between my internet-facing Nginx reverse proxy and the API service running inside a Kubernetes pod. The service is already exposed over HTTPS and uses a certificate issued by a trusted CA, but right now encryption is terminated at the proxy; traffic from Nginx to the pod still rides plain HTTP. The task is to adjust the Nginx and Kubernetes manifests so that: • Nginx re-encrypts (or directly passes) requests to the pod over HTTPS only. • The existing trusted-CA certificate chain is presented without breaking current clients. • Health checks and readiness probes keep working after the switch. I’ll grant access to the current Nginx configuration, the deployment YAMLs, and a staging cluster so you can test safely. A concise set o...

My Ubuntu-based server runs Nginx as both the webserver and an HTTP reverse proxy. Despite average utilisation staying below 50 %, I keep running into three intermittent problems: • the nginx service suddenly stops, • the whole OS occasionally freezes, and • some requests return 500 errors even though the upstream application is healthy. What I need from you is a full-scope diagnosis, clear explanation of the root cause(s), and concrete fixes. That will likely involve: • auditing current nginx and systemd settings (nginx ‑T, unit files, , etc.), • analysing kernel, journal and dmesg logs for memory, I/O or cgroup problems, • stress-testing and reproducing the 500 responses, • tuning worker processes, buffers, time-outs and any OS limit...
