System Administration Jobs

I want a small, well-structured toolkit of Bash scripts that automate three routine but sensitive tasks on my Linux servers and come with clear, client-ready documentation. The first script, , must read a pipe-delimited CSV (username|email|role|department) and for each line create the user, add them to the right primary or secondary groups, set a strong random temporary password, force a password change at first login, and log every step to both stdout and /var/log for traceability. The second, , should perform a quick security sweep: list all regular accounts, flag anything that holds UID 0 besides root, highlight users whose passwords never expire, and output a neatly formatted report that I can email or drop into a SIEM. The third, , will accept a team folder path and group name, app...

I run a small but growing company whose staff is scattered across several time zones. Because we have no physical headquarters, every employee depends on a reliable, secure technology stack to stay productive. I need an experienced IT systems manager who can step in and own that environment from end to end. Day-to-day you will: • Monitor and maintain all user workstations, keeping operating systems, apps and security patches current. • Administer accounts, permissions and backups in our cloud services (you’ll help me choose or streamline them where necessary). • Act as first-line support for the team: diagnose connection issues, resolve software conflicts and keep Zoom—our primary meeting platform—running smoothly. • Document processes so onboar...

Our company mailbox on an Ionos-hosted server is being flooded with unwanted messages and I need an expert to stop them quickly and cleanly. The mail flow passes through Ionos before it reaches Microsoft Outlook on the desktop, so whatever you implement must sit at server level and not rely on individual client rules. What I already know • The problem is on the company email server, not a personal inbox. • We run on the Ionos mail platform (not Exchange or Google). • Spam ranges from phishing attempts to the usual marketing clutter—if it’s malicious, I want it blocked; if it’s legitimate but irrelevant, I want it routed to junk automatically. What I’m hoping you will do 1. Audit current MX, SPF, DKIM and DMARC records, then correct or harden...

I’d like my Windows laptop configured so my children (aged 10-15) can use it safely without constant supervision. The setup must: • Enforce daily and weekly time limits that automatically log them out when the allowance is reached. • Block a list of questionable or distracting websites I will provide, and make it easy for me to add or remove sites later. • Prevent access to specific applications and system areas I choose, while leaving school-related programs untouched. • Let me trigger a remote log-off or shutdown from my own account or phone whenever homework needs attention. I don’t have a preferred tool yet and would appreciate your guidance on whether the built-in Windows family settings are enough or if a third-party suite (e.g. Qustodio, Norto...

I manage our university’s Student Information System and need a technically savvy partner to keep it running at peak performance while we expand its capabilities.

I want to consolidate all of our documents into a single OneDrive shared drive for our small non-profit. Fewer than ten people will be using it, and every one of them needs full administrative access so they can add, edit, and reorganise files without restrictions. What I need from you: • Configure a shared OneDrive library (within our existing Microsoft 365 Non-Profit tenant or guide me through any licensing steps). • Apply full-admin permissions to each user on the team. • Establish a simple, logical folder structure and migrate our current documents. • Provide a brief hand-off: either a quick written guide or short screenshare/video so we can maintain the drive ourselves. We’re on a tight budget, so please keep the setup lean and stick to built-in Micro...

I’m looking for an experienced IT professional who can jump in quickly and resolve a Windows-based software-installation problem for me. The application fails to complete its setup on a Windows 10 workstation and I need clear, actionable help to get it running without errors. Here is what I expect: • A live session (Zoom, Teams, or similar) or secure remote-desktop connection so you can diagnose the root cause. • Step-by-step fixes applied during the session, covering prerequisites, permissions, registry edits or command-line work if necessary. • A brief recap at the end—what you changed and how to repeat the process should I reinstall in the future.

Our stack runs on a mix of Proxmox VMs, bare-metal Linux, and Docker containers that host several resource-intensive workloads (WordPress sites, small AI services, internal tools). Performance has started lagging, so the goal is a measurable speed-up across the board—CPU, memory, disk I/O, and network throughput. Scope of the optimisation • Server side: fine-tune Proxmox (kernel parameters, storage back-ends, CPU pinning) and harden the underlying Linux hosts, making sure Docker containers inherit those gains. • Network side: analyse current routing, bridges, VLANs and SDN overlays, then remove bottlenecks and reduce latency between VMs, containers and external clients. • Application side: profile the heaviest WordPress and AI containers, tweak PHP-FPM, databas...

Our IPECS UCP is already in place and running well, but the firmware is lagging behind the current stable release. I need the system brought up to date with a clean, verified firmware-only upgrade; no hardware swaps or network re-engineering are planned at this stage unless the new software requires a minor tweak. You’ll begin by confirming the exact model and present firmware build, take a full backup, then apply the latest approved firmware from Ericsson-LG. After the flash, I expect you to restore all existing configurations, run functional tests on call routing, voicemail, and any licensed features, and provide a brief report that lists the version numbers, tests performed, and confirmation that the upgrade passed without errors. Deliverables: • Verified system backup be...

I’m looking for an experienced network and system administrator to take full ownership of our small-to-mid-sized office network. The environment is being refreshed from the ground up, so I need help at every stage: • Hardware deployment and configuration – routers, switches, wireless access points, and firewalls all need clean, standards-based builds. VLAN design, IP addressing, DHCP/DNS, and basic cabling checks are part of the work. • Performance monitoring – once the gear is live, I want continuous visibility. Please integrate the hardware into the monitoring stack of your choice (SolarWinds, PRTG, Zabbix, or similar), set sensible alerts, and give me a weekly health summary during the first month. • Security hardening – enforce best-practi...

Потрібна регулярна технічна підтримка для вже запущеного корпоративного сайту. Основний фокус — постійний моніторинг та підготовка звітів про працездатність ресурсу. Що саме очікую: • Цілодобовий або запланований моніторинг ключових показників (аптайм, швидкодія, помилки). • Короткі щотижневі та розгорнуті щомісячні звіти з аналітикою і висновками. • Оперативне повідомлення про критичні збої, щоб швидко реагувати й мінімізувати простій. Буде плюсом, якщо ви пропонуєте власні інструменти моніторингу або можете інтегрувати сайт у популярні сервіси (UptimeRobot, New Relic тощо). Доступ до панелі керування й деталі про хостинг надам після старту. Формат співпраці гнучкий: готовий обговорити тривалість та частоту звітів, а також додаткові опції, якщо згодом знадобляться ...
