I need a Coordinated Vulnerability Disclosure system built entirely from open-source components and delivered as software only—no appliances or proprietary add-ons. The core feature I must have is a robust workflow for tracking and managing reported vulnerabilities, from initial submission through resolution and disclosure. The application has to run smoothly on a Linux server, so please choose libraries and frameworks that are well supported in that environment. For user access, multi-factor authentication is mandatory; I want researchers, internal engineers, and any third-party responders to sign in with something stronger than a simple password. You are free to select or combine existing open-source projects (for example, Bug Bounty platforms, ticketing systems, or secu...

My Hetzner-hosted Linux server has locked me out of the root account. I still have full access to the Hetzner Rescue System and the console panel, but the root password itself is unknown. Your task is straightforward: bring root access back without touching any user data or service configuration. I’m comfortable granting Rescue System credentials or temporary console access so you can reboot, mount the filesystem, chroot, and update /etc/shadow—or whatever proven method you prefer. Please document each command you run so I can repeat the procedure in future emergencies. Deliverables • Root login via SSH or console confirmed working • Step-by-step notes (command history and short explanations) • No data loss or service disruption during the pro...

...Windows and Linux. My priority is a unified, maintainable codebase with a polished user interface that feels completely at home on each platform. You’ll start by recommending the most suitable toolkit or framework—Qt, .NET Core, Electron, GTK, or another actively maintained option—explaining why it balances performance, distribution ease, and long-term support. Once we agree on the stack, we’ll move through architecture design, an MVP with the core feature set, a refined production build, and finally a full hand-over that includes source code, build scripts, installation packages (an .exe installer for Windows and distro-friendly packages or AppImage for Linux), plus concise developer documentation. Success is defined by: • Seamless ins...

I need a hands-off system that reliably completes about 1 000 YouTube ad views every single day. Any ad length or category is acceptable—the key requirement is that each view counts so revenue is triggered. My ideal flow is a script or small application that: • Runs continuously on Windows or Linux without constant supervision • Rotates IPs or accounts to stay under YouTube’s radar • Randomises watch behaviour so the traffic looks human • Logs every successful ad view in a simple dashboard or text file Python with Selenium or Playwright, or Node.js with Puppeteer, would suit me well, but I’m open to other stacks if they prove more stable. Include concise setup instructions so I can deploy the tool myself and scale beyond the initial 1 ...

I already have a working WireGuard tunnel between my Linux VPS (server) and a Cudy 5 G router (client) that successfully gets me past the carrier’s CGNAT. Now I want to drop a DrayTek router running DrayOS behind the Cudy and expose it cleanly to the outside world. During a short AnyDesk / Zoom session I need you to: • Cable and route the DrayTek behind the Cudy so it sits logically on the WireGuard side of the network. • Create precise port-forward rules on the Cudy that push TCP 443, TCP 1723 and UDP 500, 4500, 1701 straight through to the DrayTek with no double-NAT surprises. • Lock my existing No-IP host to one static address and disable its auto-update feature. • Confirm from an external connection that both the DrayTek Web GUI and Smart VPN se...

...that must run smoothly for users on Windows, macOS and Linux. You will collaborate with our in-house designer to translate wireframes into a robust, secure and maintainable codebase, then guide the build right through to deployment and post-launch optimisation. Because the end product is browser-based, deep knowledge of modern web stacks is essential—think HTML5, CSS3, JavaScript (or TypeScript), plus a solid server-side framework of your choice. Clean, well-documented code, automated testing and CI/CD familiarity are must-haves; we value readability and long-term scalability over quick hacks. Deliverables • Fully functional web application accessible from the latest versions of Chrome, Firefox and Safari on Windows, macOS and Linux • Source code ...

My Amazon Linux EC2 instance is showing signs of stress—occasional service crashes and noticeable load spikes. The stack is Nginx in front of PHP-FPM, and everything sits on a vanilla AWS setup with the usual security groups and EBS volumes.

The WaSphere dashboard running on my production server (Alma Linux 9+Cyberpanel, public link: http://177…:3004/login) throws the alert “Your session has expired. Please log in again” every time I try to sign in with a freshly-created user. Over the past week I have: • SSH’d into the machine, opened the WaSphere directory, and tweaked both the .env and files. • Brought the stack back up with `docker compose up -d`. • Added an Nginx adjustment that I thought would help. Despite these changes the session error persists, so I’m convinced an overlooked or incorrect configuration is still blocking proper authentication. You will have direct SSH access, the edited .env and snippets, plus a short screen-capture video that shows th...

I want a lightweight, straight-C console tool that I can compile with a single gcc call on both Ubuntu 26.04 LTS Server and Desktop. When I launch it the program must: • Prompt for the full path of the target text file (≈100 lines). • Ask whether I intend to hide or unhide lines. • Request how many lines to process (1–5). In hide mode the utility must randomly choose that exact count of distinct line numbers (no manual picking) and make them invisible inside the file. In unhide mode it must put every previously hidden line back into its original position, effectively restoring the file exactly as it was. If the chosen file already carries a set of hidden markers, the program should warn me and exit without touching anything—no merging or overwr...
