I need an experienced network specialist to tune the performance of my Local Area Network. The primary focus is network optimization—pinpointing and eliminating the throughput bottlenecks that are slowing users down during peak hours. Here’s the flow I have in mind: first, you will remotely review the existing topology, switch configurations, VLAN design, and cabling maps. After running traffic captures and SNMP or NetFlow baselines, you’ll present a concise report showing where bandwidth is wasted or mis-prioritised. Once we agree on the findings, you’ll put the fixes in place—whether that involves QoS adjustments, firmware upgrades, or smarter port-channeling—and then verify the improvement with fresh metrics. Deliverables • Discovery repo...

I run a small, private Survival Minecraft world that usually tops out at ten friends during peak evenings. I’d like someone to take over the technical and community-facing chores so I can focus on simply playing. The immediate priorities are: • Plugin setup and upkeep – install, configure, and keep updated essential Paper/Spigot plugins (economy, land-claim, grief prevention, permissions, chat, and any quality-of-life add-ons we agree on). • Performance tuning – optimise the JVM flags, Paper config, and hardware allocation to keep TPS rock-solid even when redstone farms or exploration spike our tick load. • Light moderation – help enforce basic rules, roll back griefs with CoreProtect-style tools, and maintain a friendly chat atmosphere; no heav...

I have Acelle Mail v4.2.0 installed and a cluster of 20 VPS servers already running Postal as the SMTP backbone. In total, 300 sending domains are ready to rotate. What I need now is the layer that ties everything together—a custom domain-management module built into (or cleanly integrated with) Acelle that will let me run large-scale, cold-email campaigns safely and predictably. Key elements I expect from this module • Warm-up scheduler, blacklist monitoring, and domain-rotation management are all mandatory features. • The warm-up scheduler should work in a hybrid fashion: the system proposes an automatic ramp-up plan based on my predefined rules, I approve or adjust, and only then does it execute. • Blacklist monitoring must track spam complaints, bounce rates...

My office relies heavily on a mixed environment of Windows workstations and a growing fleet of Ubuntu machines, so day-to-day stability is critical. I need someone who can drop straight into real-world troubleshooting—swapping out failing laptop drives, cleaning up driver issues, reinstalling an OS when it is faster than patching, and keeping every system fully-patched and backed up. The immediate priority is our Ubuntu-based infrastructure: fresh server installations, user management, and routine CLI-level administration. Alongside this, I have several hardware firewalls that must be given a clean, BASIC setup—standard rules, NAT, limited port exposure, and a sanity check on default credentials. Networking touches almost every ticket that crosses my desk. You will be the...

My site feels sluggish, images take too long to appear, and I am running into storage-related limits that keep new photos from uploading smoothly. I want the whole experience to feel snappy and hassle-free again. The core of this job is performance tuning.

Once you are done, I expect visibly faster page loads on both mobile and...

I need a robust socket-based system written in Python that can manage dozens (eventually hundreds) of simultaneous client connections. Each client will push mixed data (text and binary) to the server every few minutes. The server must: • Accept and keep persistent TCP connections, identify each client by its IP/port, and store that mapping in memory for quick callback. • Route outbound messages so I can speak to any individual client on demand—think targeted commands, acknowledgements, or config updates. • Insert every payload into a customer-specific MySQL schema (one database per customer, tables you define). • Create a rolling log file per client capturing connection events, payload metadata, and outbound commands. I’m fine with your preferred con...

Necesito dejar listo el servicio DNS de mi VPS Linux para que el dominio que tengo registrado en IONOS apunte correctamente a un sitio web estático que ya está cargado en el servidor. El servidor está operativo y tengo acceso root; lo que falta es la configuración de los registros (A, AAAA si procede, CNAME, TXT para SSL) y la puesta a punto del resolutor en el propio VPS o, si lo consideras más eficiente, la delegación en los nameservers de IONOS enlazando únicamente las IP públicas. Espero que al finalizar: • El dominio y el subdominio www resuelvan a la IP del VPS. • Pueda emitir y renovar un certificado SSL (Let’s Encrypt) sin errores de DNS. • La propagación haya sido verificada con herramient...

I need an IPTV server installed and configured with Xtream Codes so that I can stream live TV, films, series, and sports from a single, easy-to-manage panel. In the question set I simply wrote “IP TV sunucu” to emphasise that I am looking for a complete backend solution; the goal is for that server to feed every common client device—Smart TVs, phones, tablets, and computers—without my users having to tinker with anything technical.

I need the entire website that is currently running on Base44 moved over to my Hostinger account and brought back online exactly as it is now. The site is a straightforward, custom-built collection of HTML, CSS and JavaScript files—no WordPress, no Wix, no external CMS—so the job is mainly about cleanly copying the codebase, setting up the new environment and making sure every link, asset and script behaves the same once the DNS is pointed to Hostinger. Here is what I consider a successful hand-off: • All site files and any accompanying assets replicated on Hostinger’s servers. • DNS records updated (or clear guidance provided) so the domain resolves to Hostinger without noticeable downtime. • SSL activated through Hostinger’s panel so the padl...

I’m looking for a seasoned RSPS developer to build a fully-functioning, PvP-only private server that mirrors the 2007 Old School RuneScape experience. Authentic tick timing, switching, special-attack formulas, prayers, and wilderness mechanics are must-haves; the server should feel exactly like OSRS the moment a player logs in and steps into the wild. You’re free to base the project on a solid open-source 317/OSRS framework or start from scratch in Java—just keep the code clean, documented, and version-controlled in Git. My priority right now is the core combat loop and overall stability. Extras such as custom items, leaderboards, or seasonal tournaments can remain optional for a later phase, so please leave clean hooks or modular systems that make future additions strai...

I’m sourcing ready-to-install operating-system images for Windows, Linux and ChromeOS. For Windows, the build must arrive fully activated; for Linux and ChromeOS I just need clean, production-ready images. In most cases I’ll ask for the current stable release, but I occasionally need an older build, so the ability to deliver either version on request is important. Every image should boot straight into the installer from ISO or USB and ship with a modern web browser pre-installed—nothing else. Supply links or cloud storage I can access immediately after payment. If a Windows activation key is required, include it and confirm that activation survives re-installation.

Project Overview: I need to build and deploy a self-hosted Home Assistant instance (based on the official open-source project: ) using Linux and Docker. Once built, I need to completely rebrand it with my own logo and brand name. Strict Rules: This is 100% cosmetic. Do not change any core functionality, refactor code, or alter the layout. Update-Safe: The branding must be applied in a way that future updates to the base open-source project will not overwrite or break our custom branding (e.g., using custom theme folders, Docker volume overrides, or CSS injection). What Needs to Be Done: Initial Build: Deploy the Home Assistant project via Docker on Linux. Brand Identity: Replace the old logo and brand name with my new ones everywhere in the system. Web UI: Update the visual styling of the ...

I need an experienced Cisco UC engineer to move our entire Cisco Unified Communications Manager 11.5 cluster from the current pair of UCS servers to a fresh BE6K-M6-K9 platform. The goal is a like-for-like migration: two nodes in an active / passive arrangement, keeping every dial plan entry, device pool, SRST reference, certificate, and license exactly as they are today. I’m looking for full, end-to-end assistance. That includes planning the cut-over, exporting and restoring the DRS backup (or using Prime Collaboration Deployment if that proves cleaner), rebuilding the cluster on the BE6K hardware, and validating that phones, trunks, voicemail integrations, and presence services all register with zero loss of service. The passive node must mirror the current HA behaviour; no new ba...

I recently swapped SIM cards and, in the process, all of the photos and videos on my Android phone vanished. I’m not sure whether they were sitting in internal memory, an SD card, or were somehow linked to cloud storage—the only certainty is that they are no longer visible on the device. I need a specialist who can: • Locate every missing photo and video, no matter where they were stored. • Restore them safely back onto the phone or extract them to a shareable drive/folder. • Provide a brief outline of what was done so I can avoid this issue in the future.

Our Sendmail server has been relaying mail through Office 365 for years without a hiccup, but as of today every outbound message fails with the log entry “stat=User unknown.” Nothing on the system was recently patched or reconfigured, so I need a Sendmail-and-Exchange-Online specialist to step in, trace the fault, and restore normal delivery. Key areas that will probably require inspection include the local / settings, SMTP relay authentication, our Office 365 connector, TLS handshake parameters, any IP or domain blocks, DNS records and, of course, the mail logs on both sides. I can supply full SSH access to the mail host plus the Microsoft 365 admin portal and message trace results. Deliverables (acceptance criteria): • Identify the root cause and document it briefl...

I need a network-savvy engineer to build and fine-tune a private WireGuard VPN that lets me stream my home content library from abroad without tripping any geo-blocks. The connection must work flawlessly on my desktop and laptop, my iOS/Android phones, and a smart-TV/streaming box in the living room, so the configuration should cover multiple device profiles. Security is just as important as unblocking: a reliable kill switch and solid DNS-leak protection have to be baked in from the start. I’m open to your preferred way of achieving this—iptables rules, OS-level scripting, or an external firewall—but the end result must automatically cut traffic the moment the tunnel drops and make sure every DNS request stays inside the VPN. Because it’s a residential setup, I&r...

Unraid is already up and running on my server; what I need now is a clean, fully-functioning ARR stack. Please install and configure Sonarr, Radarr, and Lidarr through Docker on the existing Unraid environment, wire them together with the indexers and download clients I’ll provide, and make sure everything lives neatly in the correct shares with sensible permissions. I’m open to either default or customised settings—right now I’m simply not sure which tweaks will serve me best—so I’ll lean on your experience for recommended best-practice options (e.g. quality profiles, naming conventions, path mapping, hard-linking, auto-updates). Deliverables • Docker containers for Sonarr, Radarr, Lidarr deployed and running • Each app reachable via the...
