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.

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.

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 run several sites on a Hostinger VPS and need someone who can step in each month to keep the server running smoothly whenever something breaks. The main help I’m after is hands-on troubleshooting and issue resolution—software crashes or odd errors are what crop up most often. You’ll have root access through Hostinger’s hPanel and SSH, so you should already be comfortable reading logs, restarting failing services, rolling back misbehaving updates, and applying quick patches without disrupting live traffic. When an incident occurs I’ll ping you on Slack or email; a prompt first reply and an estimated fix time are essential. Once a problem is solved, I expect a brief rundown of the cause and the steps you took so I can track recurring patterns. Typical stack...

I am ready to launch a fresh Ubuntu-based VPS that will host the TP-Link Omada Cloud SDN Controller, and I want the environment to be production-ready from day one. Your task is to install the latest Omada software, tune the underlying Ubuntu system, and lock everything down with an intermediate security posture: firewall rules, automated updates, and a proven intrusion-prevention layer (e.g., Fail2Ban or similar). Once the controller is up, I will also need a concise document that shows: • every step you took during installation and hardening, • all credentials or certificates generated, • and a clear, vendor-agnostic backup strategy (where to store the archives, how often to run them, and the exact commands or scripts). Feel free to recommend S3, rsync to anoth...

I’m looking for someone who can take me from a blank or malfunctioning drive to a fully-functional operating system, ready for everyday use.
