    I have a Windows server 2025 data center edition . already running Hyper-V and one ubuntu server running smoothly I need another one fresh install Ubuntu Server VMs spun up on it, each serving its own website over Nginx. Both sites must be reachable from a single public IPv4 address by putting a reverse proxy in front of them (SNI / host-header based routing is fine). What I’ll hand over: • RDP access to the Hyper-V host, my public IP, and DNS control for both domains. What I expect back: • Two Ubuntu LTS guests fully installed and hardened. • Latest stable Nginx on each guest, serving a basic “it works” page so I can drop in my code later. • A reverse-proxy layer (Nginx, HAProxy, or another OSS tool if you prefer) listening on the host o...

    I regularly receive batches of transaction records in CSV format from a secured sender API. For each batch I need those files programmatically relayed to a separate receiver API that is open (no auth required). I will supply the sender credentials, payload specs, and the receiver’s endpoint documentation each time a job comes up; you simply confirm you are free, move the data across, and return a quick success log. Because only the sender endpoint is authenticated, you’ll handle token retrieval or key injection on that side, then push the unaltered CSV to the receiver. Robust error handling, retry logic, and a concise report of successes / failures are important so we can audit transfers later. Typical runs are small, but speed matters. If you are comfortable scripting this i...

A user lands on the site, logs in with a simple username-and-password form, and types a request such as “open port 443 on HQ FortiGate and back up the config.” 2. Your NLP/ML layer interprets that sentence and autogenerates a complete, syntactically correct Ansible script or playbook. 3. The script is returned to the frontend for the user to review. 4.

    I keep seeing high RAM utilisation on both Oracle Linux and Red Hat Enterprise Linux servers and I want to understand, in depth, what is really happening inside the memory subsystem. More than a quick fix, I need a knowledgeable administrator who can walk me through each layer—kernel, user space, buffers, cache, swap—so I can read the numbers with confidence and spot the true culprits when usage spikes. Here is what I expect from our collaboration: • A live, step-by-step session (or series) where we run commands such as free, top, vmstat, sar and others you recommend, interpret every column, and relate the output to the kernel’s behaviour. • Practical explanations of how Oracle Linux and RHEL may differ in their memory reporting and tuning parameters. &bull...

    I need a straightforward software application that runs natively on Linux and serves as a dedicated utility tool. The core idea is already outlined on my side; once we agree to work together, I will share a concise feature list and expected workflows. Here is what matters most to me: • Clean, dependable code that compiles without hassle on common Linux distributions. • A minimal-footprint executable plus the full, well-commented source. • Clear build instructions (Makefile, CMake, or an equivalent shell script). • A short README so I can install, run, and troubleshoot the tool on my own. Any modern language that is well supported on Linux—C, C++, Rust, Go, or Python—is fine, so choose whichever lets you deliver a robust result quickly. If you l...

    I’m running a Laravel 10 bulk-media sender that talks to WhatsApp Business Cloud through a webhook. Whenever the API answers with HTTP 429, the webhook does mark the message as failed, yet the queued retry flow (RetryFailedWhatsAppJob on Redis/cloud queue) rarely fires, and when it does, the image-ID matching logic sometimes mis-aligns. The result is missed retries or, worse, duplicate sends. Here’s what needs to happen: • Repair the webhook callback so the media object returned by WhatsApp is always matched to the correct outbound record. • Ensure the job is dispatched, picked up, and processed on the existing Redis-backed queue every time a 429 occurs, honouring the current attempt counter. • Implement a reliable back-off for those 429 responses so we r...

    I need an experienced Comfy specialist to take us from a blank server to a fully functioning environment my team can rely on every day. The first priority is a clean installation and initial configuration: database, user roles, security settings, and any recommended performance tweaks. Once it is running smoothly, I’d like you to walk us through the platform’s more advanced, custom-feature workflow so we can tailor it to our internal processes. We have not yet decided whether the platform will need to hook into other tools, so I’ll look to you for advice on what’s possible and the best timing for any integrations. After setup, please deliver an advanced training session (remote is fine) that demonstrates how to extend or adjust those custom features, plus written ...

    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...

    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....
