System Administration Jobs

My NEC SV9500 PBX refuses to come back online after a routine restart. The system hangs during boot; I do not see telephones registering and I’m not sure whether any error codes flashed on the console because I wasn’t watching closely. I need an engineer who knows the SV9500 architecture, maintenance commands, and PCPro (or equivalent) to: • Connect remotely (or guide me onsite) to diagnose why the call-processing software is not loading. • Identify and clear any database, card, or processor faults preventing a full start-up. • Bring the PBX to an operational state where extensions are live and calls flow normally. Acceptance will be when the system completes its boot cycle, endpoints register, and we can place internal and external calls without drops...

My macOS laptop needs a clean, working installation of Clawd bot that I can fire up instantly to automate repetitive tasks. I would like you to handle everything—from downloading the correct build, resolving any homebrew / Python / dependency issues, right through to a test run that proves the bot can trigger a simple automation of my choice (for example, launching an app and moving a file). Here is what I expect at hand-off: • Clawd bot installed in a dedicated directory with all dependencies pinned to stable versions. • A launch method that survives reboots (command-line alias or a small Automator app—whichever you find more reliable). • One sample automation workflow set up and documented, so I can clone the pattern for future tasks. • A short, pl...

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 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...

After moving my sites from RamNode’s cloud hosting to a new VPS, several core services stopped working. WHM and cPanel are installed and accessible, yet there were issues with the site. I changed the mailservers back to cloud hosting. What I need right now is a full review and clean configuration of the server so every component—mail server, FTP service, and DNS including nameserver glue—operates smoothly. Please log in, audit each service, adjust the settings, and document any permanent changes you make. Before I repoint the real nameservers, show me a working preview link or temporary hostname that proves the sites load correctly and email delivers both ways. Please also help me verify the glue records through WHOIS, so include that in your checklist. Deliverable for...

I need my small GoDaddy-hosted mail environment moved seamlessly into Microsoft 365. There are fewer than ten individual mailboxes, and I want every message, folder, contact, and calendar entry to arrive intact. I will take care of setting up Outlook and mobile devices myself once the cut-over is complete; what I need from you is a clean, well-planned migration that avoids any mail loss or extended downtime. Scope of work • Export and import all mailbox data (email, folders, contacts, calendars) from GoDaddy to the corresponding Microsoft 365 accounts. • Update DNS/MX and any autodiscover records so traffic flows to Microsoft 365 at the agreed switch-over time. • Verify each mailbox on Microsoft 365 is fully accessible via webmail before sign-off. • Provide a c...

I run five Magento 2.4.7-p1 ecommerce stores on a single dedicated server and have discovered a redirect to the malicious domain lanhd6549tdhse.top. I need someone to trace every trace of this malware, remove it cleanly, and harden the server so the infection does not return. A fresh, full backup from last night is ready, and an antivirus already runs on the machine, but the infection slipped through.

I need fixing now for my Laptop via Anydesk. Every time I try to send a message on WhatsApp the app freezes and then shuts itself down. It launches normally, lets me type, but the moment I press “send” it stalls and crashes. Clearing the cache, reinstalling, and updating the OS have not solved it. I’m looking for someone who can quickly identify the root cause of this crash—whether it’s a corrupted install, conflicting background service, storage problem, or something deeper—and guide me through a clean, data-safe fix. Remote troubleshooting is fine so long as we preserve all chat history. Deliverables: • A stable WhatsApp that can send and receive messages without freezing. • A brief summary outlining the issue discovered and the steps...

I need someone who can comb through a Windows 11 desktop that currently houses three internal drives—the active system disk plus two older drives migrated from previous PCs—to track down several photo folders that have vanished from view. The search is strictly for photos, most of which were saved in RAW format. I still remember parts of many folder names, so you’ll have keywords to work with from the outset. I’m expecting a methodical, non-destructive approach that checks obvious paths, hidden locations, user profiles, legacy libraries, and any remnants left behind by past Windows upgrades. Feel free to lean on everything from advanced File Explorer queries and PowerShell scripts to specialized file-recovery or disk-cataloguing tools; just avoid anything that writ...

I run a computer-centric business that relies on a hybrid setup—part cloud, part on-prem servers—and I need a reliable partner to keep everything humming. Day-to-day, the help I’m after centers on two fronts: tracking down and fixing software glitches before they hurt productivity, and handling the nuts-and-bolts upkeep of our desktops, laptops, printers, and the small server room we still operate. Here’s what that looks like in practice: • Software troubleshooting: isolate crashes, apply patches, resolve compatibility issues across Windows and Linux, and speak with vendors when escalation is required. • Hardware maintenance: swap failing parts, run preventive diagnostics, clean equipment, and advise when a full replacement is more cost-effective. I r...

I need a dependable AWS hand to jump in whenever a new EC2 instance has to be launched or an existing one re-configured. The core of the work is instance setup and configuration: choosing the right AMI and size, attaching and formatting volumes, assigning elastic IPs, creating or updating security groups, installing required packages, and handing over clean, well-commented documentation so I can track every change. Speed and clarity matter to me. Most requests will be short, same-day tasks, so I’m counting on you to respond quickly, follow best-practice hardening, and keep costs in check. Comfortable with the AWS console and CLI, IAM role creation, and snapshot scheduling is essential. While the immediate focus is EC2, skill with S3 or RDS would be appreciated for future phases. If...

I oversee a distributed team across the United States that relies on a mixed fleet of Windows laptops and MacBooks. I’d like to hand off day-to-day remote control management so that my staff always has quick, reliable help whenever problems arise. The core need is user support and troubleshooting. When a user is stuck—whether it’s a driver conflict on a Lenovo, a stubborn macOS update, a Wi-Fi profile that won’t save, or an application crash—I want you to jump in remotely, diagnose the issue, fix it, and document what you did so we can learn from each case. A secure, industry-standard remote-access tool such as TeamViewer, AnyDesk, or an RMM platform you already trust is expected. I’ll provide administrator credentials and establish whatever whitelisti...

I need an experienced integration engineer who can move comfortably across IBM WebSphere, Apache Kafka and Jenkins. All three platforms are in active use, so depth in each is essential. On the WebSphere side you’ll both develop and administer IIB/ACE message flows. Expect to create new integrations, refactor existing ones, tune performance and handle deployment automation. MQ and DataPower are equally important in our landscape, so you should be able to configure queues, security, high-availability and the corresponding policies on DataPower. Kafka underpins a real-time event pipeline. I’m looking for someone who understands topic design, partitioning, replication, monitoring and day-to-day administration. Experience writing and optimising producers/consumers is a plus. Jenk...

I have a Raspberry Pi 4 that needs to boot cleanly from the current PiSDR image. Once the board is up and proven stable, I want the connected peripherals configured—no network tweaks or extra software stacks, just the peripherals. The job is straightforward: • Flash the official PiSDR image to a micro-SD card and verify the Pi boots. • Detect every attached peripheral I specify (SDR front-end, GPS-disciplined oscillator, and a small touchscreen) and make sure each one is recognised, mounted or mapped correctly, and ready for use on every reboot. • Deliver either a refined image I can flash directly or a concise step-by-step guide that reproduces your work on any fresh card. I will give you SSH access to the board and a list of the exact USB devices and HATs th...

AutoCAD stalls at roughly 95 % of the setup wizard and throws a clear licensing error, so I need a clean slate and a working program before the day is over. I am attempting to load version 2026 on a Windows 11 machine; every partial reinstall I have tried keeps leaving remnants that trigger the same failure. Here is exactly what I expect you to tackle through AnyDesk or TeamViewer today: • Completely remove every Autodesk-related folder, registry key, and licensing service. • Re-install AutoCAD 2026 from scratch. • Resolve the licensing error so the software opens, activates, and reaches the drawing workspace without prompts. • Leave me with an updated Autodesk Desktop App and a verified license screen so future updates run smoothly. I will stay connected whi...

I run a small startup with about ten Windows desktops and laptops and I’m ready to standardise them under one clean, fully licensed company image. I need an IT specialist to: • Build a reproducible “golden” Windows image that includes only licensed software and our branding. • Deploy that image remotely to every workstation with minimal disruption to my team. • Create a single admin account that lets me monitor installed software, track updates and receive alerts when anything drifts from policy. • Configure secure remote-support access through TeamViewer or AnyDesk so I can reach any device on demand. • Document the exact setup steps, licence keys in use, and a simple process for bringing new machines online. I’m open to whichever...

Outlook 2016 keeps asking for a password even though the credentials are correct. The moment I click the “Need Password” indicator it reconnects to Exchange, but the prompt returns later. Because the problem shows up on more than one workstation, I’m confident it isn’t a single-PC glitch. I’ve already walked through the usual basics—cleared the Windows Credential Manager entries, recreated the Outlook profile, checked Autodiscover records, and confirmed the Exchange certificate chain—yet the nagging prompt persists. What I need now is a deeper dive: someone who can pinpoint the root cause (whether it’s an authentication loop, cached token issue, or something server-side) and apply a permanent fix without disrupting mail flow. Deliverables...
