I need a hands-on network engineer who can spend a single day at our client’s site completing a clean install and initial turn-up of the new infrastructure. Detailed network diagrams are already prepared, so you will be able to follow clear port-by-port instructions. Your primary focus will be racking, stacking, powering on, and patching all specified devices—namely the routers, switches, and wireless access points—exactly as shown in the diagrams. Once each unit is in place, please enable console access so our remote engineers can jump in for final configuration. During any gaps in the schedule, the client may ask for light break-fix help on user equipment such as desktops, laptops, or printers. Nothing complex here—just straightforward troubleshooting to keep th...

My private server farm runs entirely on Windows Server 2019/2022 and I want a single, reliable point of contact to keep it both secure and resilient. Day-to-day, you will be hardening the network with advanced threat-detection practices—think real-time log analysis, strict firewall policy reviews, prompt patching, and well-documented incident response plans. All data protection flows through Veeam. I rely on daily image-level backups, off-site replication, and periodic restore tests, so you’ll need to stay on top of job success reports, storage consumption, and any failure remediation without waiting for me to ask. Support is part of the arrangement: when an issue or change request lands in the ticket queue, I expect timely follow-through and clear communication until closure...

My home Wi-Fi was recently breached and I can still see unfamiliar devices connecting even after I changed the password. I need an experienced network-security freelancer who can jump in remotely, pinpoint how the unauthorized access is happening, and lock the network down for good. Here’s what I expect: • Run a quick audit of my existing router settings, logs, and connected clients to confirm the intrusion vectors. • Reconfigure the router with stronger protections—WPA3 where available, hidden SSID if practical, MAC filtering, upgraded firewall rules, and a properly segmented guest network. • Verify and, if necessary, update firmware, disable insecure services (WPS, UPnP, weak remote-admin ports), and adjust DNS or VPN settings to shield traffic. •...

I’m setting up a new Survival-only Minecraft world and want it ready to welcome roughly 50-100 players without lag or downtime. Your task is to stand up the server, harden its performance and load in the exact plugins I’ll share once we begin (economy, land-claim, anti-cheat and a few quality-of-life extras). A Paper or other high-performance Spigot fork is preferred, so please configure the JVM flags, view-distance and garbage collection settings that keep the tick rate stable even during peak hours. After installing the plugins, sort out their dependencies, tune every config file, and run stress tests to be sure permissions and features behave as expected. Deliverables • A live, fully configured Survival server running the latest Paper/Spigot build • All r...

I can no longer send mail from my Microsoft 365 personal account—every message bounces back with: “This message couldn't be delivered because the sending email address was not recognized as a valid sender. The most common reason for this error is that the email address is, or was, suspected of sending spam. Contact the organization's email admin for help and give them this error message.” Nothing about my usage looks suspicious, and I have not altered security settings or changed the password recently. Outgoing mail worked fine until this block appeared, so I suspect it is a reputation or authentication issue (possible spam flag, disabled mailbox, or mis-configured SPF / DKIM / DMARC entry). Access will be provided through AnyDesk for a live session on my Win...

My Hostinger VPS was automatically shut down after malware activity was detected. It runs on Linux and already has basic antivirus software in place, yet something slipped through. I have not been able to pinpoint any suspicious files or processes so far, so the machine will need a full forensic sweep before it is brought back online. Here’s what I need, step-by-step: • Power the VPS up safely through hPanel or SSH rescue mode and capture a snapshot for analysis. • Audit every running service, scheduled task, and startup script, identifying and terminating malicious or unnecessary processes. • Locate, isolate, and delete infected files or code injections (web roots, crontabs, tmp folders, hidden binaries, etc.). • Patch vulnerabilities and harden the syst...

I am launching a new cross-platform VPN that has to stand shoulder-to-shoulder with NordVPN, ExpressVPN and the rest of the current market leaders. The finished product will ship as two native clients—one for Google Play, one for the App Store—built on the same secure core. Security is non-negotiable: the tunnel must run AES-256 with WireGuard, enforce a true No-Logs policy and expose a Kill Switch. On performance, I expect consistently high speeds and smart routing logic that automatically selects the fastest exit without user input. From the first launch the experience needs to feel effortless: one-tap connect, a clean, modern UI in line with the guidelines at , and an auto-reconnect that silently restores protection after any drop. To differentiate, I also want native ...

I’m looking for a seasoned ethical hacker to walk me through a full-scale security consultation. My end goal is to understand where my current defenses fall short and what concrete steps I should take next. Here’s what I need from you: • An initial review session where we discuss my existing environment, assets and risk tolerance. • A structured security assessment—penetration-testing techniques, threat modeling or code review—tailored to my setup. • A clear, prioritized remediation roadmap with short-term quick wins and longer-term strategic fixes. • A follow-up call to make sure I’ve interpreted and implemented your recommendations correctly.

My Plex Media Server is up and running on an Nvidia-powered box, yet 4K and even some 1080p videos stall, buffer, or drop quality when I watch on my Smart TV. On mobile I sometimes see the same buffering and lag. I’m looking for someone who can jump in remotely, inspect my current Plex settings, check Nvidia GPU hardware-acceleration, and tune the server so streams reach my TV (and phones) smoothly without constant transcodes or network spikes. You’ll likely need to: • Audit current server configuration, libraries, and storage paths. • Verify Nvidia driver versions and ensure hardware transcoding is enabled correctly in Plex. • Adjust streaming and remote-access parameters for both LAN and external viewing. • Identify network bottlenecks (router, Wi...

My personal Gmail has been compromised and all standard recovery steps I know—namely the recovery-email and phone prompts—have failed. Google’s automated flow keeps looping me back to “unable to verify,” so I’m locked out even though I can still see activity alerts landing on my phone. I’m looking for someone who knows Google’s account-recovery system inside out, can guide me through the right sequences (or submit the correct escalation forms), and help me regain full access without violating Google’s Terms of Service. Ideally you have a track record of restoring accounts after similar unauthorized takeovers and can show me how to harden security once we’re back in. Deliverables • Verified step-by-step plan tailored to my...
