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.

The job is purely about data transfer—no remote console work, no print or disk sharing—so the deliverable is a clean, documented method that lets the Windows side read from and write to the VMS system with minimal latency and full reliability. I am open to Phase IV or Phase V, as long as the end result connects the two operating systems seamlessly on today’s hardware or virtual infrastructure. What I expect from you • A working configuration (scripts, command procedures, small utilities—whatever you decide is most efficient) t...
We recently migrated a self-hosted Chatwoot instance from one server to another using Docker Compose. The migration included: PostgreSQL database (dump & restore) File storage migration from MinIO (old server) to DigitalOcean Spaces (S3-compatible) The problem: After migration, all new messages and file uploads work perfectly. However, files from conversations before the migration are broken — images, PDFs, and documents sent/received prior to migration no longer open. The old Chatwoot stored files in a MinIO bucket named chatwoot. The new setup uses DigitalOcean Spaces with a bucket named chatwoot-plantaocontabil. The files have been copied over, but the internal references (ActiveStorage blob keys/paths) no longer match the new storage structure. Example of a working URL (new...
I’m running a Debian server and need the system language switched from its current setting to Ko-kr. Your task is to: • Reconfigure the server’s locale so all system messages, man pages, and default environment variables use Ko-kr. • Verify the change persists after a reboot and is applied for both root and regular SSH sessions. • Provide a brief set of commands or a script so I can repeat the process on future servers if needed. Please work directly on Debian, avoid disrupting running services, and share a short confirmation (e.g., output of locale and localectl) once the change is complete.
I keep seeing high RAM utilisation on both Oracle Linux and Red Hat Enterprise Linux servers and I want to understand, in depth, what is really happening inside the memory subsystem. More than a quick fix, I need a knowledgeable administrator who can walk me through each layer—kernel, user space, buffers, cache, swap—so I can read the numbers with confidence and spot the true culprits when usage spikes. Here is what I expect from our collaboration: • A live, step-by-step session (or series) where we run commands such as free, top, vmstat, sar and others you recommend, interpret every column, and relate the output to the kernel’s behaviour. • Practical explanations of how Oracle Linux and RHEL may differ in their memory reporting and tuning parameters. &bull...

I need Grafana and Prometheus installed and fully configured from scratch, then Prometheus (with the usual Node Exporter) deployed on my remote Linux server so it can scrape the host and forward data. Once data is flowing, I want a clean, responsive Grafana dashboard that shows at a glance: CPU load, memory usage, disk space, inbound/outbound network traffic and total server uptime.

I need an expert to configure reliable file synchronization between my QNAP NAS and my PC. The goal is to have all selected folders stay perfectly in-sync, whether I update a file on the NAS or on the computer. Scope of work • Enable and configure QNAP’s native tools—Qsync, RTRR, or Rsync—whichever is best for two-way file synchronization. • Create or adjust shared folders, user permissions, and versioning so that sync jobs run securely. • Schedule and test the sync tasks, confirming that adds, edits, and deletes replicate both ways without conflicts. • Provide a short, step-by-step document (or screen-share walkthrough) so I can repeat or modify the setup later.

I have several Windows 11 PCs and I’m looking for someone who can get my Microsoft account’s passwords and other sign-in data to sync seamlessly between them. The built-in sync options are partially configured, yet entries saved on one machine don’t always appear on the others. Your job is to diagnose what’s blocking the sync, adjust any Windows or Edge settings, and confirm that every new password or credential I save on one PC shows up automatically on the rest. Remote work is fine as long as you can guide me through any steps that must be done locally (for example, registry edits or Group Policy tweaks). Deliverables • All Windows 11 PCs signed in with the same Microsoft account and actively syncing passwords/login data • Verification that ite...

I need a capable network engineer who can spend a full working day at my client’s premises acting as our hands-on field resource while my remote team carries out all configuration tasks. Your focus will be purely physical: rack-mounting the servers, switches, and firewalls; dressing and labeling power and Ethernet runs; attaching console and management leads; then powering everything up so we can reach it remotely. Once each device is live you’ll run quick sanity checks—simple pings, basic connectivity, and a printer test—to confirm the build is progressing as planned. Desktops and laptops must join the network without issue, and at least one printer needs to produce a clean test page before you leave. I’ll supply a clear step-by-step build guide and remain ...
I need a Windows-friendly VBS script that can hop across a list of IP addresses, open every target file it finds there, search for any 10-digit number, and place a “1” in front of each of those numbers. Some hosts may have a single file, others a whole directory tree, so the script must cope with a variable number of files per IP address. Whenever a file contains more than one 10-digit string it should modify each occurrence, not just the first or the last. Ideally the script will: • Accept a text list of IPs and a root path (UNC or mapped drive). • Recursively scan from that path downward, capturing every readable file that matches the extensions I define at runtime. • Perform an in-place edit, backing up originals with a timestamp in case a rollback is...

My SharePoint 2019 farm has suddenly lost its Distributed Cache functionality. AppFabric is reporting corruption, user profiles refuse to provision, and overall farm performance has taken a noticeable hit.

I want every Logic Pro plug-in I own—roughly somewhere between 100 GB and 500 GB of instruments, effects, and support files—moved off my Mac’s internal drive onto a fast external SSD. The goal is simple: free up space locally while keeping Logic Pro X working exactly as before, with all authorisations intact and presets loading instantly from the new location.

While you are there, please handle light break/fix tasks for the end-user area—simple checks on desktops, laptops, printers, or imaging stations to keep everyone productive during the change window. Nothing in-depth, just the typical cable reseats, peripheral swaps, and basic diagnostics. Deliverables – Routers and switches correctly mounted, powered, patched, and reachable via console from our NOC. – Quick photo log (front and back) of eac...

I need an experienced network engineer to spend one full day at a data-center site acting as my hands-on field presence while my remote team drives the configuration.

My son wants to play the PC game “Football Player,” but the download is tucked away behind a multi-part archive on an external site. I already have the direct link; what I need is someone who can: • Grab the full set of game files from that link • Safely extract and re-package them into a single, clean installer or folder that runs on Windows • Send back the ready-to-play files (or a verified cloud link) along with brief notes on anything I should know—extra DLLs, run-as-admin steps, or antivirus flags that might pop up If you normally use WinRAR, 7-Zip, or similar tools, that’s perfect. Just be sure the final result launches without errors on a standard Windows 10/11 machine. Please let me know roughly how long you’ll need once you recei...
I need an open-source fax solution deployed on a Linux host so I can both send and receive faxes from the network. Every incoming fax must be archived automatically as a PDF, and all administration—including queue monitoring, user setup, and log review—has to be handled through a clean, browser-based interface. Any stack that meets those points is fine Like ICTFax as long as it runs on a recent Debian/Ubuntu or CentOS release with no licensing fees.

I have around 35 GB of OneDrive-origin files sitting on my Mac. They appear in Finder, thumbnails even load in Quick Look, yet every time I try to open, copy, or drag them elsewhere I’m told they must be downloaded first. I refuse to sign back into OneDrive because the last time I did that the sync process wiped large chunks of my library. What I need is straightforward: make every one of those placeholder items fully accessible again, stored locally on the same Mac, while preserving the existing folder structure exactly as it is. I’ve already confirmed I have more than enough free disk space to hold the full 35 GB, so there’s no need to involve external drives or other cloud solutions. You’ll likely rely on macOS tools such as Finder’s package contents,...
I want to run a fully-functional SAP S/4HANA virtual machine on my personal Windows computer so I can practise and explore the suite on my own time.

I need a proven Airtel Black SIP configuration running on my Ubuntu machine and handled through Linphone. The goal is a clean, documented initial setup—no trial-and-error learning on my system, please.

Here’s the workflow I’m expecting: • Install or verify the latest Linphone and any required dependencies on my Ubuntu box. • Register the Airtel Black SIP account, applying the correct proxy, authentication string, and codec priorities. • Prove the setup with at least one inbound and one outbound call (I can join you on a test call). •...
I operate a cluster of Windows Server 2019 machines and need an experienced set of hands to keep everything running smoothly. Your focus will be three-fold: maintaining the servers themselves, getting our Veeam Backup & Replication environment dialled-in, and stepping in whenever a network hiccup or whitelist request appears. On the Veeam side I already have repositories in place; what’s missing is a clean, reliable backup configuration and the regular monitoring that guarantees every job finishes without warning bells. Restoration testing and documented recovery steps will be part of the routine so we can prove our RPO/RTO targets at any moment. Networking support centres on troubleshooting issues as they arise and processing whitelist updates for partners and applications tha...

I’m in the middle of an ongoing project and have run into a few stubborn issues that I can’t resolve on my own. What I need right now is straight-forward technical support with a strong focus on troubleshooting.
