System Admin Jobs

My WHM-powered Linux server has become sluggish and I can’t pinpoint why. I need an admin who lives and breathes cPanel to step in, diagnose the performance issues, and bring the machine back to full speed. The task is entirely troubleshooting-focused: you’ll investigate load spikes, slow page responses, and any other bottlenecks hiding in the stack. Deliverables • A clear diagnostic report outlining root causes • Tuned configurations or commands applied (Apache/Nginx, MySQL/MariaDB, PHP-FPM, kernel limits, etc.) • A brief post-fix summary so I can reproduce or adjust the settings in future SSH and WHM root access can be provided as soon as we agree on a start time. Please be comfortable working live on production and documenting every change you make...

I run an office network that serves roughly 250 daily users through a patchwork of Cisco, D-Link and TP-Link “Quantum” access points backed by Gigabit switches. During peak hours everyone—from desktop workstations to laptops and mobile phones—sees severe slow-down even though the backbone tests clean outside those windows. I need a wireless and LAN specialist who already knows the quirks of these three vendors to: • trace the real cause of the slow speeds (channel overlap, airtime fairness, rogue APs, cabling, controller mis-tuning, firmware, ­etc.); • tune or redesign the current configuration so that throughput remains stable during the busiest periods; • document every change and leave me with a rollback file and a short performance ...

I am building a small-scale NOC around Zabbix and need a veteran who has spent a decade or more in the trenches with the platform. The goal is to package proactive monitoring as a managed service for my customers who already buy data-security solutions—UTM firewalls, endpoint protection suites, SIEM feeds and the like. What I need from you • Initial setup: architect and deploy the Zabbix server, proxy layout and database back end, tune for high availability and multi-tenant use, and document every step. • Integration with security solutions: create or tailor templates, SNMP polls, API calls and alert rules that pull health, threat and license data from leading UTM appliances, EDR/AV agents and cloud security portals, then roll them into clear dashboards and SLA reports...

I have a short on-site engagement in Sydney CBD that needs an experienced hands-on technician. The job is straightforward—about one to two hours—but I need someone who can arrive on time, work independently, and leave the workstations fully operational before walking out the door. Scope of work • Set up and configure the new workstations • Connect and configure all peripherals we’ve supplied: printers and scanners, monitors with docking stations, plus keyboards and mice • Run basic network-connectivity tests so I can see green lights for internet and domain resources • Carry out a quick hardware sanity check (cables secure, no visible faults) and confirm each station boots cleanly to the log-in screen Success for me is simple: by the end of you...

I have a fresh server waiting for you to connect and install an open-source hypervisor—VirtualBox is my chosen platform. Once VirtualBox is in place, I need twenty fully functional desktop machines, 10 running Arch Linux and the other 10 Linux Mint. Each desktop must sit in its own isolated VM. Key requirements • Shared-folder integration between host and guest so I can move files back and forth effortlessly. • Reliable USB pass-through so attached devices appear inside the VM just as if they were local. • RDP and VNC configured on both guests for smooth, encrypted remote access. Please tune the settings for good performance over typical broadband connections. Beyond the basics, make sure the guest additions (or equivalent) are installed, networking is bridged f...

Sorry, I had to create a new project because the content has changed so much. We have a freshly configured root server with a fresh installation of BigBlueButton on it. An unsuccessful initial migration from Rocket LMS is now to be carried out on this server and, where necessary, fully configured (logo, colour schemes, payment system, etc.). The installed BigBlueButton on the root server also have to be configured to be intergrated completely with the LMS. Once everything is running smoothly, SuiteCRM should be installed and hold a short session to guide our staff through the new environment: how to launch BBB rooms, update branding assets and ensure that future updates will not overwrite the customised work. In general, the following tasks need to be carried out: • Migration fro...

I need a hands-on engineer to install and fully configure a Sophos XGS 118 at our site in RITMAY BUILDERS, Ansal Villa, Satbari Road, New Delhi 110074. Both Jio and Airtel technicians are already scheduled, so you will be able to plug straight into their hand-offs and build a clean fail-over between the two uplinks. The job covers everything from mounting the appliance to finishing live traffic tests: • Physically install and cable the XGS 118 • Create dual-WAN with automatic fail-over (Jio / Airtel) • Design and apply LAN and VLAN structure • Build firewall rules, NAT, and routing that match our current network plan • Coordinate on-site with the ISP crews plus the CCTV and Lutron automation teams to ensure their remote-access requirements are met &bull...

I need an experienced desktop support engineer who can jump in and keep our Windows workstations running smoothly. Most of the calls for help will involve installing or repairing software—chiefly Microsoft Office and our chosen antivirus package—and fixing those stubborn moments when the machine drops off the network. You’ll connect to the user’s PC, diagnose the cause, resolve it, and then leave a brief record of what was done so the issue doesn’t resurface. Key deliverables: • Correct installation or repair of requested applications • Restored network connectivity with root-cause identified • Short, clear post-session summary for my records Comfort with Windows 10/11 administration tools, registry edits, Group Policy, and solid TCP/...

I have two SaaS sites running on AWS (EC2 + RDS + S3) that I now want moved to BinaryLane () . Both stacks are fairly standard—no exotic networking or custom AMIs—so this should mainly be a clean lift-and-shift and a bit of re-wiring. Scope of work • Spin up equivalent BinaryLane instances, copy the codebases, databases, SSL certificates and cron jobs, and confirm the apps are fully functional on their new hosts. • Point the DNS once we’ve run smoke tests and I give the green light. • Leave all image and document storage on AWS S3; update the apps so they continue to read/write to the same buckets without any broken links. • Recommend and integrate a cost-effective transactional email solution (Amazon SES, SendGrid, Mailgun—whichever you feel gi...

I am rolling out a new IP-based CCTV network that must protect both indoor and outdoor areas of our facility. The job begins with a full site survey—virtual walk-throughs and existing floor plans are available—to map optimal camera positions, cabling routes, and NVR locations. Because the entire backbone will run on Ethernet, you will need to size and specify PoE switches, storage capacity, and any wireless bridges needed for hard-to-reach exterior zones. Once the bill of materials is approved, I expect you to handle or oversee physical installation, perform all network configuration (subnetting, VLANs, port-forwarding for secure remote viewing), and fine-tune the VMS so live and archived footage streams smoothly from every camera. Acceptance criteria • Complete cove...

I am moving our production DNS from a Windows-based server to a fresh Debian instance running Bind9. The new host needs to be fully authoritative for all current zones, so I will rely on you to extract every record from the Windows server, import them into Bind-compatible zone files, and validate that the answers match bit-for-bit before cut-over. Once the zones are in place, I also want DNSSEC enabled with a properly generated Key Signing Key (KSK) and Zone Signing Key (ZSK) for each zone. Please configure automatic key rollover and publish the DS records I will provide to my registrar. The goal is a seamless switchover with zero client disruption and clean validation on tools like dig +dnssec, dnsviz, and Verisign’s DNSSEC debugger. Deliverables • Debian 12 server with Bind9...

I have a concise trial assignment that will let me confirm your KiCad skills before moving into steady collaboration. Please install my “Rounder for Tracks v3.2” plugin, run it on a PCB containing angled traces, and confirm the tool rounds each track properly. Work through the various plugin settings so I can see how thoroughly you explore its behaviour. Deliverables I expect: • A brief report outlining the steps you followed, the settings you tried, and whether the results matched your expectations. • Clear, high-resolution screenshots showing the board before and after each test case. • Honest, actionable feedback on usability issues, bugs, or enhancement ideas. Solid KiCad experience and a practical grasp of PCB layout are essential, along with clear com...
