Tengo un servidor web Ubuntu alojado en Azure. Después de un ajuste en las reglas perdí todo acceso externo: no responden ni SSH (22) ni HTTP (80) ni HTTPS (443). Desde el portal de Azure todavía puedo entrar por consola de emergencia, así que la máquina está encendida; simplemente la capa de red o las reglas internas/externas están bloqueando el tráfico. Necesito que: • Analices y corrijas las Network Security Groups, reglas de firewall de la VM y cualquier configuración de iptables/ufw que impida estos puertos. • Restablezcas la autenticación SSH con claves existentes o, si fuera necesario, generes una nueva pareja y la dejes operativa. • Verifiques que el sitio web vuelve a ser accesible por HTTP...

I already have an in-house email-sending tool paired with a verification platform. Before we scale further, I want a fresh set of expert eyes to confirm that everything is configured exactly as it should be and to tighten up any loose ends you spot. Here is what I expect: • A thorough review of the current sending application—server settings, DKIM/SPF/DMARC alignment, bounce and complaint handling, throttling rules, and any other factors that influence inbox placement. • Confirmation that the verification platform is running flawlessly and catching invalid or risky addresses without slowing campaigns down. • Clear, actionable fixes applied immediately where issues are found, plus concise notes explaining what was changed so I can trace the logic later. You are f...

I need a genuine, ISP-issued static IPv4 address (Only I use, not shared) that is geographically located inside Pakistan. The line will front-end a small production web server, so uptime, clean routing, and unthrottled ports 80/443 are essential. I’ll also be running my own mail services behind the same address and will therefore require Socks 5 to be open and fully usable. Here’s what I expect from you: • Provision of the static Pakistani IP with clear documentation of the assignment. • Quick walkthrough (or concise guide) showing how to bind the IP to my on-prem machine (Linux) and verify reachability. Once the IP is reachable externally and the basic connectivity tests for the web server, Socks5 succeed, I’ll consider the job complete.

I need an experienced FreePBX professional who will teach me what I want to learn about freepbx operation and backup You can share your freepbx installation or use mine. You will look over my current installation if needed and help me fix the issues so that I can run it smoothly. So the focus is strictly on troubleshooting and ongoing support rather than fresh installation. I plan to use your experience instead of AI support. If you routinely work with Asterisk/FreePBX CLI, have a solid feel for SIP tracing tools such as sngrep or Wireshark, and are comfortable working/teaching on production systems where downtime needs to stay minimal, you are exactly who I’m after. I would like to use a help convenient with my work hours so that I don't cheat with my boss.

I already own the domain; now I need a fully-operational MailWizz environment that I can start using the moment you hand it over. You will supply and configure everything—dedicated Windows server, clean IP address, valid MailWizz license, and any underlying mail transfer agent—so I don’t have to purchase additional components or subscriptions. The build must be optimised for high-volume transactional emails. Rather than relying on third-party relays like Amazon SES, SendGrid, or Mailgun, I’d like to send directly through MailWizz itself, so please install and tune the SMTP/MTA you feel delivers the best inbox placement on a Windows stack. Key deliverables: • Provisioning of a Windows server with a fresh IP • Installation and activation of MailWizz unde...

I have a small React.js web application ready for production on a private domain. The cPanel account is already live, so I only need help with specific tasks—things like creating the production build, configuring the document root, handling SSL, setting environment variables, and making sure the deployment script runs smoothly each time I push fresh code. Once the site is live, I also need a clean, documented API that external partners can call securely. A lightweight REST endpoint is fine; just be sure it validates requests, returns JSON, and is ready for basic authentication or token headers so it can plug straight into their platform. Please bring solid cPanel experience, comfort with React-friendly build tools (npm, Yarn, Webpack or Vite), and the ability to test the new API fr...

I run several production workloads in AWS here in Singapore and need a partner who can jump in any time—day or night—without the lag a distant time zone creates. Fast, reliable WhatsApp communication is non-negotiable; that is how my team escalates issues and approves changes. Core stack you will care for: • EC2 instances that host our main applications • S3 storage buckets for static assets and backups • RDS databases (primarily MySQL / PostgreSQL) We also lean on Elastic Load Balancing, IAM, and Shield/WAF, so familiarity with those services is important.

Two Cisco ASA 5512 appliances • Integrate Microsoft Active Directory authentication for every local and VPN user, • Build an active-standby fail-over pair between the two ASAs • Upgrade the firmware to the current long-term-support release • Add a secondary Internet uplink that rides over a 4G/LTE modem; the ASA should keep the static fibre circuit as primary and fail over automatically to the mobile link only during outages. It is production system so credentials cannot be shared, all work needed to be done on a shared screen. Please bid If you know ASA CLI/ASDM inside out and have handled AD integration and dual-ISP designs

Our network relies on Cisco Identity Services Engine, but recent posture checks are failing and several policy sets are no longer behaving as intended. I need an engineer who lives and breathes Cisco ISE to dive straight into the security-centric side of the platform, isolate the root causes, and rebuild any broken logic so users are authenticated and authorized exactly as our compliance rules demand. The immediate focus is policy development, enforcement, and the associated troubleshooting workflow—no fresh installs, just refining what is already in place and making sure every posture requirement is met without disrupting production traffic. You will have full access to the existing ISE nodes, logs, and current policy matrix, plus remote console time with our network team for c...

My brand-new AlmaLinux 10 server is still empty and I already have full root access, so I’m looking for an experienced systems engineer who can turn it into a production-ready hosting platform in one sitting. Here is what I need done: • Install and license cPanel/WHM, then apply the recommended security hardening. • Replace Apache with LiteSpeed (Enterprise) and ensure the global and per-account settings are tuned for performance. • Enable CloudLinux with CageFS, LVE limits and PHP Selector so future user accounts are fully isolated. • Add Softaculous and verify that one-click installs work out of the box. • Create at least one WHM reseller package that I can clone for future resellers. • Verify that all services (DNS, Exim, Dovecot, FTP, Aut...

I’m looking for someone who can take me from a blank or malfunctioning drive to a fully-functional operating system, ready for everyday use. The task is strictly technical support focused on the installation itself—I’ll supply the license key or image, you guide or carry out the setup. Here’s what I expect: • Selection and verification of the correct OS image • Clean or upgrade installation, including basic partitioning if required • Activation, first-time updates, and driver checks to be sure the machine boots and runs smoothly If any minor post-install hiccups appear, I’d like quick pointers to resolve them, but we’re not stepping into full troubleshooting or long-term system maintenance for this project. Let me know your preferre...

I run a service center and I’m ready to streamline two key touch-points at once: inbound customer support calls and WhatsApp messaging. I am not working on CRM and ticketing system, so the solution must plug directly into both of those platforms—ideally through secure APIs or webhooks—so every interaction is logged automatically without any manual data entry. I only need straightforward rule-based flows: IVR menus for phone calls, and button- or keyword-driven replies on WhatsApp. Natural-language understanding is not required; speed, reliability, and clear routing rules are the priorities. Please propose the tech stack you’ll use (Twilio, 360dialog, Asterisk, Vonage, Dialogflow CX in “no-NLP” mode, or any other you prefer) along with the integrati...

I need a concise boundary-definition plan that lets me track human movement in a small outdoor space—think a plaza or pocket-park. You may choose either laser range-finders or LiDAR sensors; I’m flexible as long as the final solution reliably flags when a person enters or exits the defined perimeter. Here’s what I’m after: • A site-layout drawing that shows optimal sensor placement and coverage, taking into account line-of-sight, mounting height, weather protection, and power/network needs. • Configuration guidelines for the chosen hardware (recommended makes, models, beam angles, ranges, data rates). • A basic processing workflow or script that converts raw distance data into real-time boundary-crossing events I can feed into my analytics stac...

I want to spend a focused, one-hour screen-share session building and deploying a tiny standalone Python agent from my Windows laptop to Google Cloud Functions. This is purely for learning, so I need you to drive the commands while explaining what each step does. During the call we will: • create a simple “Hello World” style Python script, • configure the gcloud SDK on Windows, • deploy the code to Cloud Functions, • trigger the function and confirm it runs, and • quickly review logs and basic troubleshooting tips.

Familiarity with Python 3.x, Google Cloud Functions, and the Windows command line is essential; opt...

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 secure mess...

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 have a set of raw FASTQ files from a personal research project and I want to take them all the way through to biological insight. My primary goal is to identify differentially expressed genes, and I already have both the reference genome and its matching GTF/GFF annotation ready for you. Here is the pipeline I want to see implemented: • Initial quality check with FastQC followed by an aggregated MultiQC summary. • Adapter and low-quality base trimming. • Alignment to the reference (or transcript-level quantification if you prefer Salmon/kallisto) under a well-documented, reproducible Linux environment. • Gene-level count matrix generation, then differential expression with DESeq2 in R. • Exploratory visualisations: PCA, heatmap, and a volcano plot highl...

I run all of our transactional and marketing messages through a custom-built SMTP server, and I now need every single message we send to show a new “from” address. That address has not yet been added or verified on the server, so the first step will be setting it up properly, completing whatever SPF, DKIM, and verification steps are required, then updating the server configuration to make it the default sender. Once the address is live and trusted, I want the change enforced globally—no edge cases where an older identity slips through. After you update the SMTP settings, I’ll need a quick proof: send a few sample messages my way and show the headers so I can see the new address, correct DKIM signature, and a pass on SPF. If you have experience with Postfix, Exim, ...

I need on-site assistance in Hong Kong to measure and document the real-world speed of our wireless network. The job is strictly performance oriented—I am not looking for security or basic connectivity checks. What matters most is an accurate picture of current network speed so we can benchmark upgrades now underway. Scope of work • Visit the designated office floors and selected public areas that already have access points installed. • Run repeatable speed tests (e.g., iPerf, Speedtest CLI, or equivalent) on both 2.4 GHz and 5 GHz bands, capturing downstream and upstream throughput. • Record signal strength, client device specs, test time, and environmental notes for each location so results are reproducible. • Summarise findings in a short report that h...

I already have a trained machine-learning model sitting in a repo; now I need it running reliably on AWS. Your first task is to containerise the model (Docker) and spin it up on an AWS EC2 instance—the environment I’ve chosen for this project. Once it is live, expose a secure REST endpoint so my application team can POST data and receive predictions in real time. Low latency matters, so please size the instance with that in mind and configure autoscaling policies if you feel they will help. Model quality can drift, so the next priority is a solid monitoring stack. I want to see Accuracy, Latency and Error rate streaming into CloudWatch (or Grafana/Prometheus if you prefer) with clear dashboards and alarms that alert us when thresholds are breached. Feel free to add extra me...

I already have an IoT mobile app with its backend up and running; however, the user experience suffers from noticeable latency. My goal is to polish the codebase, trim anything that consumes resources unnecessarily, and move the entire stack from Google Firebase to a VPS that uses MQTT for real-time messaging. What I need you to tackle • Profile both the mobile client and the existing Node/JavaScript backend, pinpointing functions, background tasks, or logging that slow the app down, then refactor or remove them without breaking current functionality. • Reduce round-trip time for screen loads, device data sync, and control commands to well under a second on a normal 2G connection. • Stand up a secure VPS (Ubuntu preferred), install and configure an MQTT broker such as...

I’m bringing in an external expert to tighten up a mixed-vendor environment that spans Cisco, Juniper, HPE/Aruba switching and a FortiGate firewall. Most of the day-to-day items run well, yet lingering issues around VLAN design, trunk consistency, OSPF versus static routes, and a few NAT quirks at the edge are starting to show. The single highest-value task is establishing a reliable Site-to-Site VPN between two offices so we can retire an aging MPLS circuit. Beyond that, I’d like you to review current firewall rules, clean up redundant objects, and confirm that inter-VLAN routing on the switch stacks lines up with our security zones. SolarWinds is in place for monitoring; if you see gaps in SNMP polling or alerting, feel free to tune those as you go. To keep expectations c...

Our VMware Cloud Foundation 9 deployment is ready for its management-domain build and I need the underlying network finished off quickly and cleanly. The hosts sit on Aruba switches, and the remaining tasks centre on switchport updates, IP/DNS adjustments, and a complete firewall rollout so the VCF bring-up checks pass first time. Work to be completed • Aruba switchports: create or modify trunks/access ports, tag the correct VLANs for Management, vMotion, vSAN, NSX-Edge and future workload domains, then document every change. • IP addressing: finalise the allocation plan, reserve management ranges and update any DHCP scopes. • DNS: add the A/PTR records for SDDC Manager, vCenter, ESXi, NSX and support services so name resolution works end-to-end. • Firewall: im...
