Ubuntu Jobs

I’m running the Flare Data Connector (FDC) client on a production-grade Mainnet node packaged in Docker. Since a recent configuration change, every submit2 call now returns: “Merkle root not available: attestation in consensus but not confirmed” I need a clean, permanent fix that restores normal Merkle-root confirmation on mainnet without breaking existing services. Scope • Inspect my current Dockerised setup, config files, and any recent edits I made. • Trace the submit2 flow inside the FDC client to locate the confirmation bottleneck. • Apply and test the patch so Merkle roots confirm as expected on mainnet. • Provide a concise write-up of what went wrong and how you resolved it, including any commands or code snippets I must keep ...

I’m building a fresh SA-MP Mobile role-play server and need an experienced Pawn developer to move it from “just launched” to “fully stable.” The immediate job is to dive into the existing gamemode and clean up the mission/event scripts. They work, but they’re rough around the edges and don’t yet flow the way a live RP community expects. At the same time, I want the vehicle-handling parameters tuned so cars feel consistent across different client devices. While you’re in the codebase, I also need you to hunt down and eliminate the three big pain points the testers keep flagging: random crashes, noticeable frame-rate dips, and a handful of features that sometimes just stop responding. The sooner those are gone, the sooner we can open the doo...

We need a full-stack technical staff member with expertise in Java microservice development (Spring Cloud), message queues (Kafka/RabbitMQ), databases and caching (MySQL/Redis), Linux server deployment and maintenance, Nginx gateway configuration, and distributed system debugging to complete the deployment.

I have an existing code-base that needs to be compiled, configured, and deployed on a CentOS 7 server. The stack spans several languages (the repository mixes Java, Python, a bit of C++, and some PHP utility scripts) so I need someone comfortable moving through polyglot projects without breaking stride. （Developed independently using a non-Java language） The immediate goal is a repeatable deployment: building the artefacts, resolving library dependencies, wiring in systemd service files, and validating that everything starts cleanly after a reboot. You’ll work directly on my CentOS 7 instance (SSH access provided) and document any package or kernel-level tweaks you make so I can reproduce the setup on staging and production later. Because the code also ships to a small cross-pla...

I’m looking for someone who can install and configure OpenClaw on a fresh Linux environment (Ubuntu 24). Once it’s in place I need it tuned specifically for running automation scripts—no other features are required right now. The job is considered finished when: • OpenClaw is installed from source or packages, whatever is most stable on Ubuntu 24. • The automation‐script module is enabled and a sample script executes without errors. • I have a brief README outlining the key commands to start, stop, and update the service. If you’ve compiled similar tools or set up CI-style script runners before, this should be straightforward. open claw open site and login and bet bhave of me what i say to him ho and this mach and bet liek that

I’m ready to rebuild my GoDaddy VPS: it currently runs CentOS and hosts my company websites behind Nginx with SSL enabled. I want the server re-imaged to the latest stable Ubuntu, with every element of the existing stack preserved and an additional n8n instance installed. Scope of work • Perform and store an off-box, full backup of all site files, databases, and current Nginx configurations before any changes begin. • Re-provision the VPS on Ubuntu, harden the OS, and apply basic firewall rules. • Restore my websites, bringing Nginx back online with the original virtual host blocks and SSL certificates so no visitor notices the change. • Install n8n (Docker or native systemd service—whichever fits best on Ubuntu) and expose it securely over HTTPS ge...

I need reliable freelance computer-hardware engineers who can visit my customers’ offices and homes across India and carry out installation services—specifically Linux installation on their machines for everyday desktop use. Here’s what a typical call looks like: I send you the location and preferred Linux flavour (most often Ubuntu or Mint, though customers occasionally ask for Fedora or Debian). You arrive on site with a bootable USB/DVD, install the OS on a new or existing desktop or laptop, set up common drivers, configure the network, and verify that everything—from Wi-Fi to printers—works smoothly before hand-over. I cover any reimbursable travel expenses that we agree on in advance, and you invoice me once the job is signed off by the customer. So...

I recently moved my custom PHP / MariaDB e-commerce site to a new Ubuntu virtual dedicated server. Since the switch, every page—home, product, checkout, you name it—now loads noticeably slower even though CPU and RAM usage stay low. The job is straightforward: dissect and tune the stack so the site performs at least as quickly as it did on the old box. I’m specifically after smart adjustments to , vhost files, , php-fpm pool settings, and —buffer sizes, innodb settings, query logging, connection limits, the works. Deliverables • Optimised configuration files for Apache, PHP-FPM, and MariaDB, commented so I can see what changed. • A brief report (bullet points are fine) showing baseline vs. post-tuning load times and the reasoning behind each tweak, so...

I have a brand-new VPS with Hostinger and need it fully configured right away. The server is running Ubuntu, and its sole purpose will be to host websites reliably and securely. I’ll give you root access plus the Hostinger panel credentials; from there, I expect a streamlined, production-ready environment set up without delay. Please bring your own best-practice checklist—speed, stability, and basic hardening are what matter most to me right now. Deliverables • Update Ubuntu to the latest LTS patches • Install and configure a web-server stack (Apache or Nginx—your call, as long as it’s stable) • Enable a firewall, SSH key authentication, and basic fail2ban or equivalent protection • Set up one test virtual host so I can point a domain a...

I have, 40-core machine with 1 TB of RAM that needs to be turned into a practical development box for my team. The goal is to have both Windows Server and Ubuntu Server installed side-by-side, each ready for daily coding, testing, and collaboration. Here’s what I need from you: • Plan and carry out the installation of the two operating systems, making sure they coexist cleanly (dual-boot, virtualization, or any proven approach you recommend). • Partition and configure storage so that each OS has ample, clearly labeled space. • Enable remote access for multiple developers, with sensible user and permission settings already in place. • Apply baseline security hardening and system updates so we start from a solid, up-to-date foundation. Once finished, I s...

Ich habe eine frische OPNSense-Installation (Version 25.7) und möchte sie in mehreren Remote-Sessions über TeamViewer gemeinsam fertig einrichten. Dabei soll die Firewall nahtlos in unsere Active-Directory-Umgebung eingebunden und für den täglichen Betrieb vorbereitet werden. Folgende Arbeiten sollen innerhalb der Sessions erledigt werden: • Grundkonfiguration inkl.

My goal is to prove that 50 completely separate Indian embassies can collaboratively train a powerful intrusion-detection model without ever sharing raw traffic logs. Each embassy keeps its packets local, trains an IDS in Python, then ships only the updated weights to a permissioned blockchain that averages them and sends back the enhanced parameters. Key points I need turned into code: • Dual-framework training loops: the local agent must be able to switch between PyTorch and TensorFlow so each site runs whichever stack its engineers prefer. • Attack coverage baked into the dataset pipeline: the IDS must correctly classify Malware, Phishing, and DDoS patterns. Synthetic generation for edge cases is fine as long as the final validation shows clear detection rates for all three...

I have an Ubuntu-based box with two physical interfaces: the wired port will face a public network, while the built-in Wi-Fi card (or any other you advise) will broadcast a private hotspot. I need that machine to behave as my main router, tunnelling every outgoing connection through a VPN so users on the Wi-Fi side enjoy secure browsing at all times. Here is what I expect: • The LAN interface pulls DHCP from the public line and forwards nothing until the VPN is up. • The Wi-Fi interface advertises an SSID of my choice, hands out local addresses, and transparently pushes all traffic through the VPN tunnel (OpenVPN or WireGuard—whichever you feel delivers greater stability). • NAT, DNS, and firewall rules must be configured so clients connect instantly without e...

I have the original Turbo Pascal source code of a classic dial-up BBS. I now need it refreshed for today’s networks and hardware while keeping the old-school spirit intact. The first priority is a clean build that runs natively on Ubuntu (64-bit). After that, I will also want Windows 11 and ARM binaries, so please structure the project with cross-platform portability in mind from day one. Core objectives • Eliminate all pre-2000 date logic and make the code fully Y2K-compliant. • Replace the COM-port/modem routines with an integrated Telnet server so users can connect over TCP/IP without external helpers. • Modernize the interface where it matters for functionality—clearer menus, smoother navigation, and optional theme hooks—while respecting the ret...
