Linux Jobs

I’m putting together an intensive up-skilling program for my in-house technical team and need an experienced network administrator who can double as our trainer. The sessions must cover both traditional, rack-and-stack data-centre networking and modern cloud-based design, with plenty of live demonstrations and hands-on labs. Your background should show many years configuring routers, switches and enterprise firewalls on the physical side, then translating the same principles into AWS and Azure—plus some exposure to Oracle Cloud. We’ll dive deep into VPC/VNet architecture, site-to-site VPNs and load-balancer patterns, while constantly mapping those topics back to their physical counterparts (subnets, VLANs, ACLs, HA pairs, etc.). What I need from you: • A concise sy...

I have an Asterisk instance that needs a fully functional IVR linked to our SIP trunks. The core requirement is simple: callers should be greeted, routed through a concise menu, and seamlessly bridged to the correct internal extensions or external numbers. I already have the server and SIP credentials; what I need is your expertise in writing the dial-plan, recording or loading the voice prompts, and making sure calls flow reliably both ways. Configuration must be clean, well-commented, and resilient so future menu changes are straightforward. Once everything is in place I’ll run live tests with you to confirm: • IVR menu plays correctly and follows the designed call flow • SIP trunk registers and handles inbound and outbound calls without drops or codec issues •...

I’m launching a CPQ-driven webshop that must talk directly to new license server. My priorities are straightforward: • Users will sign in exclusively through Microsoft Azure AD SSO. No local usernames or social-logins—just Azure AD with proper role mapping. • After authentication, customers need the usual CPQ flow (configure → price → quote → checkout) and, on completion, the system must call the license server’s API to create or update the customer’s subscription license automatically. • Every product in the catalogue is subscription-based, so the cart, checkout and subsequent renewals have to respect recurring-billing rules. I’m flexible on the underlying commerce platform—whether that ends up being Shopify, WooC...

I need a hands-on Microsoft Azure specialist to work beside me in Hyderabad on a series of production-grade, Python-driven cloud components. The solution relies heavily on Azure Functions, Storage Accounts, API Management, and the Power Platform, with additional expertise in CRM applications being highly desirable. Practical knowledge and experience with these are crucial. Project highlights: • Build and refine Python-based Azure Functions that expose secure REST endpoints. • Configure Blob/Table Storage Accounts for both hot and archival data, including lifecycle rules and role-based access. • Publish those endpoints through Azure API Management, adding policies for throttling, caching, and OAuth2. • Connect everything to Power Apps and Power Automate so business user...

I’m looking for an experienced C++ developer who is comfortable working in a Linux environment to track down and resolve a functionality bug that’s affecting one of my applications. The codebase already compiles and runs; however, a key feature is not behaving as intended. Here’s what I need: • Investigate the source to identify the root cause of the malfunction. • Provide a clean, well-commented patch or pull request that addresses the issue. • Supply build instructions (Makefile or CMake) and any test cases you used to verify the fix. • Include a concise summary of the changes so I can follow your logic. The project does NOT require UI tweaks or performance tuning—just a solid functionality repair. You’ll have SSH or Git acces...

I need a fresh Compute Engine instance spun up on Google Cloud Platform running the latest long-term-support release of Ubuntu. After provisioning, you will: • Secure the server (SSH keys, ufw, fail2ban, automatic updates). • Install and configure Nginx as the reverse-proxy / web server. • Install PHP-FPM (current stable) with common extensions required by Laravel. • Install and tune PostgreSQL, then create an initial super-user and empty database. • Pull a clean Laravel skeleton into /var/www, set correct permissions, and confirm that php artisan migrate runs without errors. • Configure Nginx server blocks so that visiting the external IP shows Laravel’s welcome page over HTTP and HTTPS (Let’s Encrypt certificate). • Deliver a si...

I run a production MySQL database on a Hostinger VPS and need a reliable partner to keep it healthy month after month. Each cycle you will: • Take full and incremental backups, store them off-server, and verify integrity • Review and tune slow-query logs, indexes, and configuration for peak performance • Apply the latest MySQL and OS security patches, harden permissions, and run vulnerability scans You’ll have root/SSH and phpMyAdmin access, and I expect a short report after each visit summarising what was done, any issues found, and recommended next steps. Everything must be scheduled so there is zero or minimal downtime for my users. If you’re experienced with Hostinger panels, mysqldump, Percona Toolkit, and general Linux server hardening, let’s...

I need my Ubuntu droplet on DigitalOcean fully hardened and served behind Cloudflare SSL. Your first task is to configure Cloudflare so the site loads over HTTPS without warnings; Full or Full (Strict) is fine as long as it’s end-to-end encrypted. Once SSL is sorted, lock the server down. SSH is the only exposed service, so it must be bullet-proof: key-only logins, non-standard port (if practical), root login disabled, fail2ban (or similar) in place, and an automatic e-mail that alerts me—showing IP, user, date, and time—every time someone successfully authenticates. Complement that with: • UFW/iptables rules limiting inbound traffic to the essential ports. • Unattended security updates. • Log rotation and basic integrity checks (e.g., Lynis report or equ...

I need a clean, production-ready Python module that connects to the Zerodha Kite Connect API and proves end-to-end functionality—from session authentication right through to placing and modifying live orders. The code should follow good object-oriented practices, handle exceptions gracefully and keep credentials secure. The immediate goal is to: • authenticate with my API key/secret and request token • subscribe to market data streams via WebSocket • fetch historical price data on demand • place, modify and cancel orders programmatically Please build the solution using the official kiteconnect Python package wherever possible, but feel free to improve on its abstractions if you can demonstrate clearer structure or easier reuse. A concise README that ...

My 5G home connection is delivered through an Archer NX200 5G router and, like many 5G plans, it sits behind CGNAT. Because of this, I cannot reach my internal network from the outside world. The goal is clear: Remote Access. I need to log in reliably to my Computers, Smart Home Devices and Security Cameras, as well as a small PBX and a Draytek firewall. Dynamic DNS is already running with NOIP, yet CGNAT keeps every incoming request from ever reaching the LAN. What I’m looking for is a practical, reproducible way around that limitation: • A working solution that lets me initiate inbound connections (HTTPS, SSH, VoIP, etc.) from anywhere. • Detailed, step-by-step configuration on the Archer NX200 5G and any additional hardware, tunnel, or cloud service you recomme...

I have an STC 5G connection running on a TP-Link Archer NX200 router. The connection is behind CGNAT, meaning I do not have a real public IP. I am looking for an expert to provide a solution to get a Dedicated Static Public IP so I can remotely access my internal network (Router management, SIP devices, etc.) using my noip DDNS Conditions: I cannot upgrade to a Business SIM card. I do not want to run a local PC 24/7 as a bridge. I just need a working Static IP solution that routes traffic from the outside directly into my local network. Please propose your method and how we can implement i

I need a full-featured workforce management web application built on a classic LAMP stack (Linux, Apache, MySQL, PHP). The system will let me store detailed worker profiles, track time and attendance, allocate daily or weekly tasks, monitor performance, and automatically calculate payroll. Users will sign in via email-and-password or their preferred social account, and a second-factor step must be available to anyone with elevated permissions. Dashboards and permissions must stay tightly separated: Admins and Managers handle configuration, task assignment, and reporting, while Workers simply view their schedules, check in / out, request leave, and see their own stats. Key deliverables • Responsive web interface with clean, modern UI • Modules for Profiles, Attendance & ...

I need an expert who knows the Panasonic KX-NS100 inside out to take over ongoing maintenance and, more urgently, to hunt down stubborn routing problems. At the moment we are plagued by ghost calls, fake trunk activity and sporadic audio drop-outs that confuse users and clog the logs. These symptoms point to deeper call-routing faults, so I’m looking for someone who can dive straight into ARS tables, COS settings, SIP trunk parameters and firmware quirks to pin down the real cause, clean it up and stop the phantom traffic for good. You’ll be given remote access via VPN or TeamViewer during our business hours so you can trace packets, watch live call traffic and adjust the configuration in real time. Once the issues are eliminated I’d like concise documentation of every...

CSF Firewall & Malware Scanning ModSecurity & Rootkit Hunter SSH & System Hardening + 10 more Server optimisation • Initial setup & configuration – secure the OS and WHM, tune Apache / Nginx, PHP-FPM, MySQL, DNS and mail services, set up automated off-site backups, firewall rules and basic monitoring. • Ongoing maintenance – keep AlmaLinux and all cPanel components patched, update PHP versions and extensions, rotate logs, renew SSL certificates and verify backups weekly. • Rapid issue handling – diagnose and fix any account-level or serv...

My site is fully built and lives on , yet the domain refuses to resolve. I already added what I believe are the correct DNS records, so the problem sits squarely in the domain-pointing stage. Something in the current configuration is off and I need a fresh set of expert eyes to identify and fix it. The job is straightforward: • Review the existing A, AAAA, CNAME, and any related records for ledartistry.com. • Correct the entries so the domain cleanly routes to the server. • Test propagation and confirm loads the live site worldwide. Please work directly in the registrar’s dashboard (or guide me step-by-step if access is required) and validate your changes with tools such as dig, nslookup, or similar. The task is complete once the domain resolves without error...

I need a lightweight AI-driven script that can log in to our FMX account, sweep through every maintenance ticket ever opened across our 51+ properties, and export the full record—text fields and attached photos—in one pass. All tickets must be saved as CSV rows while every photo lands in an organised folder structure: property name → unit number → ticket-date, with filenames that echo the same pattern. FMX does not expose a native backup button, so the agent will likely rely on Python, Selenium (or a creative use of any unofficial endpoints) to crawl, download, and rename files automatically. I’m open to other tool choices if you can deliver a repeatable one-click run that a non-technical manager can launch whenever we need another snapshot. Because both t...

I need a full-featured Video Management System that I can compile and run on a Linux environment. The solution must follow a clean server-client architecture, include 100 % source code, and scale reliably to at least 1 000 simultaneous camera streams drawn from a wide mix of global CCTV brands (ONVIF or equivalent interoperability is a must). Two core capabilities are non-negotiable: smooth multi-camera live view and fast, timeline-based playback of recorded footage. Everything—connection handling, recording, storage management, and UI—has to remain responsive even under heavy load. If you already support complementary functions such as motion-triggered recording or smart alerts, feel free to highlight them, but live view and playback come first. The initial focus will be on ...

Title: Python Developer Needed – Browser Automation with Proxy Integration & Session Management Description: We are looking for a skilled Python developer to build a secure browser automation script for managing multiple independent data sessions. Project Scope: We already have a basic script that launches a browser with specific settings (similar to Playwright/Puppeteer with headless=False and geolocation support). We need you to: 1. Integrate Proxy Management: Connect our system to external proxy providers (supporting HTTP/SOCKS5, residential, and mobile IPs). 2. Implement Session Isolation: Ensure each launched browser instance has a completely separate environment (cookies, cache, local storage). One session must never interfere with another. 3. IP Assignment Logic: Bui...

I want a complete, ready-to-use SMTP server that lives on my Windows machine and lets me push out high-volume campaigns without the usual caps yet still places messages in the inbox, not the spam folder. Please build, configure, and fine-tune everything so the service runs smoothly with no username-and-password layer (that requirement is intentional because the environment is fully firewalled on our side). The core of the job is the full installation and optimisation of the SMTP engine you feel is best for Windows—MailEnable, hMailServer, PowerMTA, or another proven option are all fine as long as deliverability is strong. I also need the surrounding essentials: correct PTR, SPF, DKIM, and DMARC records, IP warming guidance, plus any queue-management or throttling tweaks that help ke...

I have a brand-new Windows 11 Server where both Docker Desktop (latest stable release) and LM Studio are freshly installed. Everything launches, yet containers inside Docker cannot reach the internet and LM Studio obviously inherits the same limitation. I need the networking issue diagnosed and cleared so standard pull / push commands, package installs and external API calls work without manual proxies or work-arounds. Once connectivity is solid, I would like LM Studio configured for simulation tasks only—no production workloads. Please audit the machine’s CPU, GPU and RAM, then recommend and load the most suitable local AI model so I can start running research simulations straight away. You will receive full Remote Desktop access; I’ll stay on standby for firewall tw...

I’m drowning in junk that keeps slipping into the work mailboxes on my own domain, so I need an email-security specialist to tighten things up fast. The accounts are not on Gmail or Outlook; they’re hosted directly on my domain, and right now the basic filtering isn’t doing the job. Here’s what I’m after: audit the existing server set-up, update any DNS records (MX, SPF, DKIM, DMARC), tune or replace the current spam-filter rules, and leave me with a clean inbox that still accepts every legitimate message. You’ll get temporary access to the control panel and DNS so you can: • Inspect mail logs and current filter scores • Correct or add SPF, DKIM and DMARC records • Configure SpamAssassin (or a similar tool) and fine-tune thresholds ...

I want a small, well-structured toolkit of Bash scripts that automate three routine but sensitive tasks on my Linux servers and come with clear, client-ready documentation. The first script, , must read a pipe-delimited CSV (username|email|role|department) and for each line create the user, add them to the right primary or secondary groups, set a strong random temporary password, force a password change at first login, and log every step to both stdout and /var/log for traceability. The second, , should perform a quick security sweep: list all regular accounts, flag anything that holds UID 0 besides root, highlight users whose passwords never expire, and output a neatly formatted report that I can email or drop into a SIEM. The third, , will accept a team folder path and group name, app...

I already have the basic LoRa modules on hand and now need a complete solution that turns them into a smart lamp I can manage from a browser. The lamp must offer smooth dimming, full-spectrum colour change and the ability to follow a user-defined schedule. Through the web app I want three distinct control modes: • a real-time dashboard where sliders and colour pickers immediately push changes over LoRa, • optional voice commands (Web Speech API or similar) for hands-free operation, • and a panel of quick “predefined settings” such as reading, relax or wake-up scenes. Please handle both the embedded side (firmware for the LoRa node driving the LEDs) and the front-end/back-end that serves the browser interface. I’m comfortable hosting on a small VPS...

Our company mailbox on an Ionos-hosted server is being flooded with unwanted messages and I need an expert to stop them quickly and cleanly. The mail flow passes through Ionos before it reaches Microsoft Outlook on the desktop, so whatever you implement must sit at server level and not rely on individual client rules. What I already know • The problem is on the company email server, not a personal inbox. • We run on the Ionos mail platform (not Exchange or Google). • Spam ranges from phishing attempts to the usual marketing clutter—if it’s malicious, I want it blocked; if it’s legitimate but irrelevant, I want it routed to junk automatically. What I’m hoping you will do 1. Audit current MX, SPF, DKIM and DMARC records, then correct or harden...

I already have a working Python script that gathers hotel data for an academic study, but all traffic must now exit through a legitimate VPN endpoint located in one specific country. I need clear, step-by-step guidance to get this running on my Linux server without interrupting the scraper’s flow. Scope of work • Recommend non commercial VPN provider (NordVPN, ExpressVPN, Surfshark, or another comparable option) that allows API or CLI control. • Supply installation commands and configuration files (OpenVPN or WireGuard) that lock the connection to the required country. • Show how to automate reconnection on reboot or network drop, confirming the IP still resolves to that country. • Demonstrate, with a short Python snippet, how to trigger the scraper only a...

I’m moving a bare-metal server at Hetzner over to a fully virtualized environment and want the foundation built right the first time. Here’s what I need: • Clean installation of the latest stable ESXi on the Hetzner host, followed by all current updates and patches. • Basic performance tuning so the hypervisor is ready for production workloads (CPU scheduling, datastore alignment, SSD caching if available, etc.). • Creation of well-structured subnets for multiple tenant VMs. • Firewall rules and protection logic on my MikroTik RouterOS appliance that will sit in front of the ESXi host, including NAT, filter, and basic DDoS hardening. I'm awaiting to order the server and necessary requirements for the setup; you will have to provide all require...

My Baileys-based WhatsApp integration is working, but it is starting to lag under heavier traffic. I need an experienced developer who knows the Baileys library inside out to: • Profile the current code, identify the CPU, memory and I/O bottlenecks, and refactor or re-architect where necessary to improve throughput and lower latency. • Verify that every optimised change remains fully compatible with the Web version of WhatsApp, including session handling, QR login, message sending/receiving, media uploads and reconnection logic. • Provide a concise report of the issues discovered, the steps taken to fix them and before-and-after performance metrics (e.g. average response time, messages per second, memory footprint). Acceptance criteria – Messages and media must...

I need a specialist to configure and verify DNS settings on my domain to ensure seamless integration with three SMTP providers: AWS, MailGun, and Brevo. The tasks include setting up SPF, DKIM, and DMARC records, ensuring all configurations are correct, and conducting thorough testing to confirm functionality across all providers. I am facing issues with domain verification due to incorrect DNS details. I need assistance in resolving this and ensuring proper configuration for AWS, MailGun, and Brevo.

Need an existing Art of Conquest private server/emulator for 5-10 friends. Android support required. No commercial use. Need server setup. Do you have a working server? Can you demo it before payment? Budget: $150.

My MySQL 5.5.18 instance is limping along after a corruption event—system tables open, but every InnoDB table throws errors. The server is only “partially functional,” so I have powered it down and kept all data files intact (ibdata, ib_logfile*, .frm, .ibd, relay/binlogs, ). Remote log-in isn’t possible; you will need to walk me through everything step-by-step while I work directly on the box. What I need is a complete, reliable FULL backup of every database, including the damaged InnoDB tables, so I can spin up a fresh 5.7+ server later. I am comfortable following detailed terminal commands; I just need an expert plan and real-time guidance to: • Mount the data directory in a safe environment (ideally using Percona XtraBackup, mysqlbackup, or a comparable t...

I need a turnkey script that logs into Facebook Marketplace, navigates through every active “Cars for Sale” listing, and extracts only the seller’s contact information—name, profile URL, any displayed phone number, and the direct Messenger link. The script should save these fields to a clean, well-formatted CSV and refresh the file automatically every day without manual intervention. Please build it in Python; Selenium, Playwright, or a similarly reliable headless solution is fine as long as it can handle Facebook’s infinite scrolling, dynamic content, and occasional anti-bot measures. Cookie-based login or a secure credential file is acceptable, but the process must stay within Facebook’s terms of service. I’ll deploy this on an Ubuntu VPS, so in...
