Ubuntu Jobs

I have a fresh Proxmox installation in place and now need an experienced hand to complete the next step: configuring a set of Linux-based virtual machines from the ground up. Your job is to handle the full system setup and configuration workflow—networking, storage assignment, template creation, and any tweaks required so the VMs boot cleanly and are ready for application deployment. Please bring solid, demonstrable experience with the Proxmox VE interface, CLI utilities, and typical KVM/QEMU guest-optimisation practices. Once you’re done I expect: • A working pool of Linux VMs (Debian or Ubuntu preferred, but I’m open to other mainstream distros if you recommend them) • Basic resource limits, bridge/VLAN networking configured, and a brief hand-over note exp...

I’m facing persistent outbound packet loss on my Linux server. The problem appeared a few days ago, right after I upgraded my hosting plan, and it has started to affect production-level traffic. Latency is acceptable and inbound packets arrive cleanly; only the outbound stream is dropping frames. I need someone who can jump in immediately, trace the root cause, and apply a permanent fix. Typical tools for the job might include tcpdump, traceroute, iptables, nftables, netstat, or any monitoring utilities you prefer—as long as the solution is clearly explained and reproducible. Acceptance criteria: • Outbound traffic shows 0 % (or normal-range) packet loss under load tests. • A short summary of what was wrong and the exact commands or configuration changes you app...

I have a fresh Ubuntu box that must be turned into a fully-functional, production-ready web server. The core of the job is server setup and ongoing management: securing the OS, installing the full web stack, and making sure everything runs smoothly day-to-day. The server will host multiple sites, so I need virtual-host configuration, SSL (Let’s Encrypt) automation, log rotation, routine backups, and monitoring in place. I have not committed to a particular web engine yet; if you feel Apache, Nginx, or Lighttpd would serve my traffic profile better, present your reasoning and we’ll proceed with the best fit. Deliverables • Hardened Ubuntu (latest LTS) with all updates applied • Chosen web server installed, tuned, and benchmarked • Firewall & fail2ban con...

Busco un profesional con experiencia real en recuperación de webs comprometidas, hardening de servidores Linux, seguridad web y configuración avanzada de Cloudflare. Hemos sufrido un ataque: comprometieron nuestra web y el servidor fue infectado hasta el punto de que terminó participando en un ataque DDoS hacia terceros. Como consecuencia, Google marcó nuestro dominio como spam, pese a que antes teníamos una reputación muy buena. Situación actual Tenemos una copia de seguridad completa de la web. Disponemos del servidor con Ubuntu 24.04. La web ya estaba detrás de Cloudflare, pero aun así fue comprometida. Necesitamos volver a publicar la web, dejarla plenamente operativa y blindar la infraestructura al máximo. Qu&eacu...

I need a Python-based bot that can open each abuse-report page, load the correct form, and submit the details I pass in via JSON or a simple CSV. The first three targets are non-negotiable—DCMA, Google, and Cloudflare—because I file most of my takedown notices there. I also want the same script to recognise when a domain’s WHOIS form is required and, if no form exists, fall back to sending a templated abuse email to the registrant or hosting provider. Headless automation with Selenium, Playwright, or another stable browser driver is fine as long as it reliably handles captchas, hidden fields, and dynamic JavaScript. The core logic should be cleanly separated so I can add more providers later without touching the form-filling engine. Deliverables • A fully comment...

Technical Mentor & Operative Architect: HA Ubuntu Cluster (Mailcow, Apache, MariaDB Replication) Job Description: [IMPORTANT: READ CAREFULLY BEFORE APPLYING] I am NOT looking for someone to just build a server and hand over the keys. I am looking for a Technical Mentor / Instructor and Operative Architect who will build a high-availability (HA) SaaS infrastructure on Ubuntu Server together with me. The goal is full knowledge transfer. You will act as my "Co-Pilot," teaching me every step so that I can maintain, troubleshoot, and scale the system myself. You should also be open to a long-term relationship for future Q&A and support. The Tech Stack & Requirements: OS: Ubuntu Server (Hardened). Orchestration: Docker & Kubernetes (K3s/MicroK8s preferred). Mail: ...

We are looking for a Senior Developer with experience in Node.js, OpenAI API, and vector databases to finalize an AI chatbot. The chatbot is hosted on our VPS (Ubuntu), and the backend is already functional, connecting to MySQL for conversation history and Qdrant for RAG (Retrieval Augmented Generation) functionality. The main objective is to fix a critical bug and implement significant improvements within an estimated timeframe of 10 to 15 days. TASKS TO PERFORM: 1. Fix Error 400 (Token Limit): The file currently sends the entire MySQL history to the OpenAI API, causing the API to crash due to the token limit. A history management strategy is required, such as a sliding window (e.g., keeping the first message and the last 8 messages) or an active conversation summary. 2. Prompt and Te...

I’d like a private Survival server built on my Aternos account and fully loaded with the mods I enjoy. The focus is a smooth, vehicle-friendly experience for a small group of friends (no more than ten players online at once). Here’s what I need: • Install the exact Vehicle mods I specify (think MrCrayfish’s Vehicle Mod and similar). • Add reliable Optimization mods to keep tick rates healthy within Aternos’ memory limits. • Include a handful of Custom mobs and items mods that I’ll list for you. • Configure everything so the whole pack plays nicely together—no ID conflicts or broken recipes. • Tweak server and mod config files for performance, lag-free chunk loading, and stable TPS. • Test the server, then hand me ...

I need a dependable AWS hand to jump in whenever a new EC2 instance has to be launched or an existing one re-configured. The core of the work is instance setup and configuration: choosing the right AMI and size, attaching and formatting volumes, assigning elastic IPs, creating or updating security groups, installing required packages, and handing over clean, well-commented documentation so I can track every change. Speed and clarity matter to me. Most requests will be short, same-day tasks, so I’m counting on you to respond quickly, follow best-practice hardening, and keep costs in check. Comfortable with the AWS console and CLI, IAM role creation, and snapshot scheduling is essential. While the immediate focus is EC2, skill with S3 or RDS would be appreciated for future phases. If...

Mi equipo presenta fallos constantes ligados al sistema operativo: pantallas azules, bloqueos inesperados y lentitud al arrancar. Busco a alguien con experiencia en soporte técnico y reparación de computadoras que pueda: • Diagnosticar la causa raíz de los errores del sistema operativo (Windows / Linux, según convenga). • Aplicar las correcciones necesarias: reparación de archivos dañados, restauración de servicios, actualización de controladores o reinstalación in-place si hiciera falta. • Optimizar el arranque y el rendimiento general, asegurando que no queden procesos colgados ni conflictos de compatibilidad. • Entregar un breve informe final con los pasos realizados y recomendaciones preventivas. ...

I have a Telegram bot written in Python and an Asterisk server already exposing the ARI interface. What I now need is a clean bridge between the two so that a simple text command sent to the bot can spin up an outbound call, play an IVR menu, record the conversation, and finally report the result back to the same chat. Here is the flow I have in mind: • A user types a command such as /call <number> in Telegram. • Your code uses ARI (ari-py or any other reliable ARI client) to originate the call. • On answer, the callee is taken through a short IVR tree that I will supply as audio prompts; the bot just needs to play them and collect DTMF. • The entire interaction is recorded and the recording URL or file is posted back to the chat once the call ends. ...
