System Administration is a highly specialized field in the Information Technology (IT) sector. It involves a variety of tasks related to the maintenance, configuration, and reliable operation of computer systems, such as networks and core services. System Administrators not only manage the daily operations of these systems, but also have the responsibility of ensuring these systems are secure, protected from malicious attacks and software vulnerabilities.

A System Administrator is capable of optimizing system operations to ensure maximum uptime and efficiency using solutions like automation. This can help organizations save on costs and resources. An expert System Administrator can also identify areas where additional system resources are needed, create disaster recovery plans, automate processes, reduce risks, provide technical advice and implement overall security policies.

Some areas that should be addressed regularly by System Administrators include information security measures, disaster recovery solutions and infrastructure planning. All of this helps ensure that an organization's mission-critical systems remain up-and-running no matter what the situation may be.

Here's some projects that our expert System Administrator made real:

  • Setting up a secure backup process for companies
  • Troubleshooting login issues for laptops
  • Installing software for server control panels
  • Managing complex server configurations
  • Automating systems setup and configuration
  • Creating content for social media accounts
  • Enhancing availability, managing traffic and protecting from disasters
  • Debugging applications on Exchange Server
  • Scheduling data flows using SQL Server Agent
  • Restoring access to webpages

System Administration is an important job that requires expertise to master. With its complexity comes huge responsibilities - handling a controlled computing environment of a company or organization without compromising data security. If you have a project or idea that you want to be handled by an experienced System Administrator, Freelancer.com has you covered on finding one that meets your requirements.

    I’m running a small Windows cluster—no more than five nodes—all hosting .NET services, and I want OpenTelemetry Collector installed and tuned so I can see CPU usage, memory usage and network traffic in near-real time. The job is to produce a repeatable, production-ready setup: • Windows-compatible Collector binaries and all required receivers/exporters • A clear, commented YAML configuration that gathers CPU, memory and network metrics • An automation script (PowerShell preferred) that installs the Collector, registers it as a service and applies the config across 1-5 nodes • A concise guide showing how to verify the metrics from a fresh node and extend the config later Acceptance criteria • After following your guide on a clean node, m...

    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...

    Eliminate Spam on Ionos Server

    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...
