Linux Jobs

I need a complete platform that can tell—quickly and with a high degree of accuracy—whether an email address is usable. The core of the build must cover: • Syntax verification • Domain verification • Mail-server (SMTP) verification Those three checks have to run in a single pass so the user gets a clear “valid / invalid / unknown” status without waiting around. You are free to choose the stack, but solutions that lean on reliable libraries or services for DNS look-ups and SMTP handshakes (for example Python with dnspython and smtplib, or a Node.js equivalent) will go to the top of the pile. I expect: – A web interface where I can paste or upload a list and watch the progress in real time. – A clean JSON API that mirrors the sa...

I need a secure, lightweight VPN application built for both and Android. The interface can stay minimal; stability, speed, and protocol flexibility are the real priorities. Core capabilities I expect: • Kill switch that reliably blocks traffic if the tunnel drops • Split tunneling so the user can choose which apps bypass the VPN • Support for the following protocols or transport layers: ssh, ssl, udp, v2ray, and websocket • A menu of multiple server locations that I can expand later through simple JSON or similar remote config No in-app user-authentication flow is required; the build should assume pre-provisioned profiles or embedded credentials. Deliverables: 1. Clean, well-commented source code (/Kotlin or Java/) 2. Signed release builds ready for TestFli...

I’m looking for an online tutor based in India who can guide me through intermediate-level administration of both Linux and Windows Server environments. On the Linux side I want practical, session-based coaching in system administration, security and firewall management, and shell scripting.

We are getting multiple OT projects and need more hands to support us in terms of this. I’m consolidating several Industry-grade PCs that run bespoke Python applications into our existing Operational Technology environment. The immediate goal is to create a clean, well-documented integration pathway that lets these machines exchange data safely with the rest of the plant network while respecting every cyber-security control already in place. Here’s what I’ll hand over on day one: current network maps, the Python sources, and a short list of approved protocols (mainly Modbus/RTU). From you I need a streamlined integration plan, the actual Python interface code or refactor, and clear documentation that anyone on the OT team can follow without hunting for tribal knowledge....

Quiero implementar en mi servidor Linux un sistema OMR escrito en Python que me permita elaborar, procesar y calificar hojas de respuesta de 1 a 100 preguntas. Necesito que desde la propia interfaz gráfica pueda: • Diseñar plantillas personalizadas: definir número de preguntas, incluir nombre de la institución y cargar el logo. • Reservar cuatro columnas de dígitos (0-9) que el alumno sombreará para generar su código interno; por ejemplo, 1101 identificará “PRIMERO A – Estudiante 01”. • Escanear la hoja PDF o imagen, identificar automáticamente al estudiante mediante esas columnas y leer cada burbuja para asignar la nota. • Guardar los resultados directamente en MySQL y permitirme co...

I want a single, turnkey application that watches my CCTV feeds, spots shop-lifters in real time, recognises grocery products on the shelves, and keeps a live head-count of customers. The core model must be YOLO, and I need the exact same code-base to compile and run on both Windows (desktop with NVIDIA GPU) and a Raspberry Pi 4. Video sources vary—some cameras stream RTSP over IP while a few older analog units reach the NVR through a capture card—so the program has to accept either type without manual re-configuration. For product recognition I care only about groceries; no clothing or electronics labelling is necessary. The model should be trained (or fine-tuned) on the most common supermarket items so false positives stay low even when shelves are crowded. Key expecta...

Description I’m hiring an experienced Open Tibia developer to deploy a modern 13+/14.12 stack using Canary (OTBR) and deliver a complete working foundation: server + client + website accounts, with proper backups and rollback. This is an assets-based 13+/14+ project (not 8.6 / legacy). 1) Server (Ubuntu 22.04 VPS) Install/configure Canary (OTBR 14.12+) MariaDB setup Proper config + ports + firewall systemd services with auto-restart Confirm clean restarts and stability Start with a standard map base (I’ll move to a custom map later) 2) Client (Windows) Compile OTClient Redemption (Windows) Preconfigured connection (no IP editing) Basic branding (name/logo) Package as downloadable ZIP Auto-update setup for client files/modules/assets (versioned) 3) Website (AAC) ...

I have a fresh Ubuntu 22.04 VPS ready and I want a fully working Open Tibia server running version 13.x or newer. I am happy to go with either Canary or TFS—whichever you feel will get us to a stable, live server fastest. My own attempts stalled mainly at the client-connection stage, so the critical piece for me is having at least one client (official Tibia or OTClient, I am flexible) connect reliably to the server once it is online. What I need from you: • Compile or install the chosen engine on the VPS, configure it, and verify it boots without errors. • Walk me through the minimal config changes so I understand what was done. • Provide a working client package—or clear instructions for obtaining and patching one—that logs straight into the serve...

I need to link one incoming GSM leg with a SIP participant inside FreeSWITCH so both callers join the same live conference room without noticing any difference in media or signaling. The end result must feel like a single, seamless conversation. Key requirements • FreeSWITCH must act as the bridge and mixer. • The conference room has to support call recording (start automatically and save to disk) and allow me to mute or un-mute either participant from the console or an API. Current environment – A working GSM gateway already delivers calls to FreeSWITCH through SIP. – An existing SIP trunk is in place for the VoIP side. – Root access to the FreeSWITCH server is available. Deliverable 1. Step-by-step configuration (dial-plan snippets, conference profi...

I have a fully-built business website written in that currently lives on a temporary project URL. The site’s sole purpose is to showcase our services, so it needs to load quickly, sit behind HTTPS, and remain SEO-friendly. Your task is to take the existing repository, build it, and make it publicly accessible on my own custom domain. Key deliverables: • Root and “www” versions of the domain pointing to the live build • Valid SSL certificate with automatic renewal • Clean, repeatable deployment flow (Git-based or CI) plus a short note explaining how to trigger future releases If you’re comfortable with Vercel, Netlify, AWS, or a similar platform and can handle DNS changes, environment variables, and any edge-cache configuration, this sho...

Emails sent from my cPanel-hosted domain have suddenly stopped landing in Hotmail / Outlook inboxes. There is no listing on public black-hole services and Microsoft support insists the IP is not formally blocked, yet every message to @hotmail, @outlook and @live addresses is silently dropped. Key context • The mail is generated by the default cPanel mail service (Exim). • No recent changes were made to DNS, SPF, DKIM, rDNS or server configuration. • My only troubleshooting so far has been opening a ticket with Microsoft; the response pointed me to general guidelines without lifting the block. What I need – A thorough diagnosis of why Microsoft is filtering or throttling the IP. – Remediation steps applied (SPF / DKIM / DMARC alignment, rDNS, HELO bann...

I have a Lenovo ThinkPad T480 waiting for a fresh, security-first Debian installation. The goal is a fully hardened, privacy-respecting daily-driver that ships with BOTH Mozilla Firefox and Brave, each pre-tuned for strong tracking-protection and fingerprint-resistance. This is an ADVANCED hardening job. Beyond the base install I’ll need full-disk LUKS2 encryption, secure boot/Libreboot if the hardware permits, locked-down BIOS settings, kernel and sysctl tweaks, AppArmor (or comparable MAC), DNS proxy with encrypted queries, and a firewall configured to best practice levels. I did not select a specific firewall in the form, so feel free to recommend whether UFW, iptables or firewalld is the right fit for an always-on laptop that roams between trusted and untrusted networks. Delive...

I have a fresh Ubuntu server ready for a clean, secure Nextcloud deployment. I need the latest stable release installed, served over HTTPS with Let’s Encrypt, and the system hardened with sensible measures such as UFW and Fail2ban. Data should live on a separate mounted volume and the whole stack must update and back up automatically. If you are comfortable layering in popular office suites like Collabora Online or OnlyOffice later, mention that—those may become follow-up milestones once the core install is solid. Deliverables • Fully working Nextcloud instance reachable at my domain via TLS • One administrator account delivered to me securely • Clear, copy-pasteable documentation (or an Ansible/compose file) so I can repeat or restore the setup anytime ...

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...

I want to launch a fully-featured, cloud-hosted lottery platform built on a hardened Node.js backend with a reliable database layer. New players will sign up with a classic email-and-password flow, then complete KYC before they can fund their wallet or join a draw. The exact KYC data points can be finalised together, but the process must be seamless and compliant. Core flow • A user tops up an internal wallet via PayPal (gaming category enabled), buys entries, and watches their balance update in real time. • On draw day a server-side, provably-fair randomiser selects winners; every draw, ticket purchase, and payout is written to an immutable audit log. • From my side I need an admin dashboard that shows live player stats, transaction history, and lets me trigger or sc...

I need an end-to-end web application written in pure Go, backed by a MySQL database. The core focus is clean, idiomatic code that can be compiled and deployed on a standard Linux server without fuss. 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. If you prefer containerisation, feel welcome to include a Dockerfile so the whole stack can spin up locally with a single command. Deliverables...

I’ve built a custom web application and it’s almost ready for production. Before the public rollout, I want a rigorous penetration test that will expose any weakness and help tighten every layer of security. The assessment must be hands-on and realistic, covering the full stack rather than a purely theoretical review. Scope My priorities are clear: • Code review – comb through the source for injection points, authentication flaws, insecure dependencies, and logic errors. • Network-level probing – map open ports, misconfigured firewalls, and potential lateral-movement paths. • Server configuration – evaluate patch levels, TLS setup, permissions, and hardening of the underlying OS and web server. Primary Goal The sole purpose is to imp...

I need a capable network engineer who can spend a full working day at my client’s premises acting as our hands-on field resource while my remote team carries out all configuration tasks. Your focus will be purely physical: rack-mounting the servers, switches, and firewalls; dressing and labeling power and Ethernet runs; attaching console and management leads; then powering everything up so we can reach it remotely. Once each device is live you’ll run quick sanity checks—simple pings, basic connectivity, and a printer test—to confirm the build is progressing as planned. Desktops and laptops must join the network without issue, and at least one printer needs to produce a clean test page before you leave. I’ll supply a clear step-by-step build guide and remain ...

I need a developer to create a dedicated communication-management tool that runs natively on Linux. The core requirement is the ability to establish, track, and gracefully close sessions over both TCP/IP and UDP. All connection handling, queueing, and basic error management should happen inside the tool so that client applications can speak through a clean, well-documented API instead of implementing their own socket logic. This tool must be system centric installed on our Linux server Here is what I have in mind: • Command-line operation is fine for the first iteration, but please structure the code so a lightweight GUI or web dashboard could be bolted on later. • Clear logging of connection events, dropped packets, and throughput statistics is essential—I’ll be p...

I’m running an InHand IG502 cellular gateway and need a focused Python add-on that exposes the unit’s current RSSI (raw dBm) as a holding register inside the built-in Modbus server. The immediate aim is simply to monitor signal quality; once the value is available we will pass it through our existing RS-485 link into the DNP3 layer of the external SCADA. Key points you should know while coding: • Device: InHand IG502 (OpenWrt-based, Python 3 available). • Output format: raw signal strength value, no scaling or percentage. • Register must be readable via Modbus-TCP and Modbus-RTU so I can map it downstream. Byte order can be little-endian; just document what you use. • Communication onward to DNP3 happens on my side, so the script only has to populate ...

I’ve just finished deploying a new Android mobile application and everything appeared to go smoothly—until I tried to launch it. Right after installation the app attempts to talk to the backend and immediately throws a server error. The APK itself installs without complaint; the trouble starts only once the first request is sent. I need someone to dive in, locate the root cause on the server side, and implement a clean fix so the app can connect reliably every time. Access to the server, source code, and crash logs is ready for you as soon as we agree to move forward. Please bring experience with common Android back-end stacks (Node, PHP, Java, or similar) and a methodical debugging approach. Once resolved, I’ll confirm the build installs and runs error-free on multiple ...

I need a reliable script that logs into Placementindia and pushes my vacancy details without any manual input. The tool should store template data, fill every required field, submit the form, and then confirm success so I can see at a glance what went live. Inside a small, browser-based dashboard I want two key abilities: • schedule automation so I can decide the exact days and times each role goes out • one-click “auto post” that instantly publishes a job when I hit the button The posting frequency isn’t fixed; some days I may blast several openings, other weeks none at all, so the scheduler has to respect whatever plan I set. Use whichever method makes the process most stable—headless browser automation (Puppeteer, Playwright, Selenium) or direc...
