I need a seasoned security professional who can step in at a moment’s notice to keep our Netskope and Check Point estate running flawlessly. The immediate priority is true on-demand technical support: when an alert spikes, a policy breaks, or a new SaaS application appears, I want to know you can connect, troubleshoot, and restore full protection without delay. Most of the work centers on the Netskope CASB/SWG stack and perimeter firewalls running Gaia OS. You should be comfortable tracing traffic through both platforms, fine-tuning policies, fixing rule-base anomalies, and explaining the changes you make so my in-house team stays in the loop. Experience with broader cloud security architectures is a plus; it often helps when integrations with Azure AD or AWS accounts start acting u...

I’ve installed a Hirschmann EAGLE40 industrial firewall and now need a specialist to walk it from factory defaults to a production-ready state. The hardware is racked, powered, and reachable through both the web interface and SSH; what’s missing is a solid rule-set, proper interfaces, and clean logging so the device actually protects the plant network rather than just sitting in the traffic path. Here’s what I expect: • You review the current blank configuration, discuss my network layout, and translate that into interface zones, NAT (if required), and a concise set of access rules. • You advise on best-practice hardening for an EAGLE40—admin account lockdown, firmware verification, logging to our Syslog server, and fail-safe settings. • You loa...

I need an Azure-based file server set up from scratch so my team can use it primarily for secure file storage of everyday documents and spreadsheets. Roughly 11 – 50 colleagues will be connecting, so permissions, performance and reliability all have to be configured with that scale in mind. The job covers creating the storage account, provisioning an Azure Files share, integrating it with Azure AD/AD DS for seamless authentication, and mapping it so Windows and macOS users can access it as a standard network drive. I also want quota alerts enabled and a clear backup snapshot schedule so nothing is lost. Once the share is live, I’ll need a concise hand-over guide that shows how to add or remove users, adjust NTFS-style permissions, and expand capacity later. Deliverables: &bu...

I have several gigabytes of raw complex I/Q captures taken across C, X, Ku, Ka and millimetre-wave bands, and I need the information hidden inside them extracted within a week. The job starts with demodulating the bursts, moves through full protocol reversing, and finishes with packet-level inspection that pinpoints the signal type, service provider and any network identifiers. Scope of work • Focus on satellite and MMWave waveforms—no vendor documentation is available. • Wireshark is the preferred environment for final packet dissection; use any supporting tools you like (GNU Radio, URH, inspectrum, etc.) along the way, provided the workflow remains reproducible. • Convert the raw I/Q into clean baseband, map the frame structure, decode the traffic and load it ...

I’m running a Linux VPS on Ubuntu and need a fresh OpenVPN installation configured as a site-to-site tunnel to my office network. Default security settings are fine—no extra encryption tweaks or two-factor layers required—so the goal is simply a reliable, auto-starting link that routes selected subnets both ways. Here’s what I expect from you: • Install the latest OpenVPN packages, enable IP forwarding, and apply any necessary UFW/iptables rules. • Create the CA, keys, and certificates, then build matching server and peer configurations. • Supply the peer-side .ovpn (or equivalent) file and guide me through importing it on our edge router or secondary Linux box. • Verify traffic flow end-to-end (ping, basic service checks) and ensure the ...

My Huawei MA5600T-01 needs to report itself as a different model in the system. The specific target is flexible—MA5600T-02, ‑03 or even ‑04—so long as the change is recognised by the OLT’s software and downstream management tools. I am pursuing this for internal technical reasons rather than a feature upgrade or hardware repair, so the board, firmware and service profiles must remain fully functional after the swap. Here is what I expect from you: • Identify the safest method (CLI, XML config, board ID rewrite, or firmware patch) to alter the model string. • Provide or execute the exact commands/patch, verify the new identifier shows correctly in display version / display board, and ensure services come back online. • Supply a concise rollback proce...

Our BGMI (Battlegrounds Mobile India) infrastructure occasionally freezes when traffic surges. I want to put a permanent stop to that by building a preventive DDOS shield that covers every critical touch-point—login, in-game communication, and matchmaking. You will begin with a quick audit of the existing network layout and traffic patterns, then design and deploy a solution that blocks volumetric and application-layer attacks before they can overwhelm the servers. I expect minimal additional latency for legitimate players, clean documentation of every rule or service introduced, and a repeatable playbook I can apply to new nodes as we scale. Deliverables • Security architecture diagram and written rollout plan • Hardened configurations applied to the login, game, a...

My Dell PowerEdge T640 refuses to start. The system gives error lights and the power LED simply blinks. I have already: • double-checked all power connections • swapped in a known-good power supply • cleared CMOS and reset the BIOS None of these steps helped, so the fault appears to be on the motherboard itself. I’m looking for an experienced server-grade hardware specialist who can: 1. Walk me through advanced board-level diagnostics to pinpoint the failed component(s), or accept the board for bench testing if that proves easier. 2. Carry out (or instruct me on) component-level repair—re-soldering, replacing VRMs, caps, or any other defective parts discovered. 3. Verify that the board posts successfully and produces a stable, error-free boot. 4...

I have a fresh Proxmox installation in place and now need an experienced hand to complete the next step: configuring a set of Linux-based virtual machines from the ground up. Your job is to handle the full system setup and configuration workflow—networking, storage assignment, template creation, and any tweaks required so the VMs boot cleanly and are ready for application deployment. Please bring solid, demonstrable experience with the Proxmox VE interface, CLI utilities, and typical KVM/QEMU guest-optimisation practices. Once you’re done I expect: • A working pool of Linux VMs (Debian or Ubuntu preferred, but I’m open to other mainstream distros if you recommend them) • Basic resource limits, bridge/VLAN networking configured, and a brief hand-over note exp...

I’m facing persistent outbound packet loss on my Linux server. The problem appeared a few days ago, right after I upgraded my hosting plan, and it has started to affect production-level traffic. Latency is acceptable and inbound packets arrive cleanly; only the outbound stream is dropping frames. I need someone who can jump in immediately, trace the root cause, and apply a permanent fix. Typical tools for the job might include tcpdump, traceroute, iptables, nftables, netstat, or any monitoring utilities you prefer—as long as the solution is clearly explained and reproducible. Acceptance criteria: • Outbound traffic shows 0 % (or normal-range) packet loss under load tests. • A short summary of what was wrong and the exact commands or configuration changes you app...

I manage a small group of VIP users who expect white-glove treatment whenever something goes wrong. Their day-to-day pain points fall into two buckets: • Software installation and configuration: from first-time deployments to tricky patching and plugin conflicts across Windows and macOS. • Connectivity hiccups—specifically frequent disconnections or an outright inability to join the network. I’ll route tickets to you through our help-desk portal (ServiceNow), and you will step in remotely via RDP, AnyDesk or VPN, diagnose, resolve, then document the fix in our knowledge base so the same issue never reaches the escalation queue twice. Clear, jargon-free status updates to the VIP are essential; I measure success by resolution time, user satisfaction scores and clean...

I run a PHP-based webhook on a Hostage VPS KVM8. During traffic spikes the endpoint suddenly answers with HTTP 429 instead of the expected 200, so the calling service retries and eventually fails. The code itself has no limiter, which makes me suspect a server-level restriction that I’m not yet aware of. Your task is to trace the component issuing the 429s and tune or disable the rule so the webhook survives peak loads. It could be an Nginx/Apache rate-limit, ModSecurity, fail2ban, iptables, or something similar—I’m open to whatever you find. Acceptance criteria • Pinpoint the exact service or module returning 429 • Apply and document a configuration fix (or clean, minimal code patch if that proves necessary) • Stress-test the endpoint and demonstra...

Our campus network runs on a Fortinet stack—FortiGate firewalls at the core and FortiAP access points across three buildings. I need an experienced Fortinet administrator to tighten security, build out VPN connectivity, and tune ongoing visibility. Scope of work • FortiGate Firewall – create or refine security policies that segment users, servers, and guest traffic while following best-practice hardening. • FortiGate Firewall – set up site-to-site and remote-access VPNs, test fail-over, and document the steps so I can replicate them. • FortiGate & FortiAP – enable and verify logging to our existing syslog/SIEM, ensuring alerts surface the right information without noise. • FortiAP – confirm wireless profiles and VLAN assignment...

I’m putting in a modest public Wi-Fi service—think 200 Hectars Farm size—and I need an engineer who can own the end-to-end network setup. The target load is no more than 50 simultaneous users, so the design should balance rock-solid reliability with sensible hardware costs. Here’s what I’m after: • Produce a simple network plan that covers coverage mapping, access-point count/placement, and backhaul requirements. • Recommend specific hardware (APs, controller or cloud-managed option, PoE switch, firewall) that’s readily available in my region. • Configure the SSID(s), security (WPA2/WPA3-Personal plus guest isolation), basic traffic shaping, and a branded captive portal for terms-of-service acceptance. • Provide clear documenta...

I’m looking for an experienced developer or system/network specialist to help me configure a Windows-based AI proxy application.

Each visit (or remote session) should end with a concise service report noting work completed, parts consumed, and any follow-up actions you recommend. Acceptance criteria for every engagement: • Fault identified and rectified or a clear action plan provided when parts are on order. • Preventive check...

I need an India-based tutor who can take practical based highly interactive online sessions covering Linux DevOps fundamentals, broader Cloud concepts, and hands-on AWS workflows. The audience already understands the basics, so the material should sit at an intermediate level—deeper than “Hello World” demos yet not so advanced that we lose learners who have only a year or two of real-world exposure. Azur will be added advantage not mandatory Here is what I expect: • A clear session roadmap that blends DevOps culture, CI/CD pipelines, container orchestration, general cloud architecture patterns, and AWS-specific services such as EC2, S3, IAM, CloudFormation, and Lambda. • Live delivery via Zoom, Google Meet, or a similar platform, with screen-sharing, demons...

My PC gaming sessions in Dubai are being plagued by high ping, random connection drops, packet loss, and a range of other performance hiccups. I’m on a cable line right now, but it clearly isn’t tuned for competitive play. I’d like an expert who can visit my apartment, run proper diagnostics on-site, and leave me with a rock-solid, low-latency connection. Here’s the flow I have in mind: • On-site assessment of the current cable setup (modem, router, internal wiring, NIC settings). • Immediate optimisation or replacement of any mis-configured hardware or cabling you find. • Clear before-and-after metrics—ping, jitter, and packet-loss reports—so I can see the improvement. If additional gear or an ISP plan change is advisable, walk m...

The Envision 1500 unit is already on-site at the customer location in Bø i Telemark, Norway. I need an English-speaking field engineer to visit, connect the device to the local network, complete the on-box configuration, and run a basic functional test so we can sign off the job remotely.
