Administration système Jobs

I’m looking for an online tutor based in India who can guide me through intermediate-level administration of both Linux and Windows Server environments. On the Linux side I want practical, session-based coaching in system administration, security and firewall management, and shell scripting. For Windows Server, the focus should be Active Directory management, server configuration and deployment, plus security and patch management. Each topic needs to be demonstrated live, with time for me to replicate the steps on my own lab machines during or immediately after the call. We can meet on Zoom or Google Meet for 2–3 hours a week, preferably evenings or weekends. Deliverables • A structured lesson plan that maps out the sequence of sessions • Recordings or sess...

I have a Lenovo ThinkPad T480 waiting for a fresh, security-first Debian installation. The goal is a fully hardened, privacy-respecting daily-driver that ships with BOTH Mozilla Firefox and Brave, each pre-tuned for strong tracking-protection and fingerprint-resistance. This is an ADVANCED hardening job. Beyond the base install I’ll need full-disk LUKS2 encryption, secure boot/Libreboot if the hardware permits, locked-down BIOS settings, kernel and sysctl tweaks, AppArmor (or comparable MAC), DNS proxy with encrypted queries, and a firewall configured to best practice levels. I did not select a specific firewall in the form, so feel free to recommend whether UFW, iptables or firewalld is the right fit for an always-on laptop that roams between trusted and untrusted networks. Delive...

My single-domain server on Virtualmin is about to lose its SSL and I can’t switch to any outside certificate provider, so I need a fresh Let’s Encrypt SSL generated and installed right away. I’d like you to: • Trigger a clean Let’s Encrypt renewal inside Virtualmin • Apply the new certificate to both the domain and Webmin/Usermin services so every port stays secure • Verify that the site, mail, and control panel all load without browser warnings You’ll have /Virtualmin access via Anydesk ONLY. Once you finish, I want to see the green padlock in every major browser and the certificate details reflecting the new expiry date. I’m ready to move immediately—please let me know how quickly you can jump in. $20 is the MAX budget.

My priority is to bring in professionals with solid technical skills who can jump onto projects at short notice and deliver real, measurable results. Whether your background is in programming, data analysis, system administration, or a related discipline, if you thrive on solving problems with code and technology I’d like to hear what you can do. Here’s what will help me decide quickly: • A concise overview of your core technical strengths and the tools you rely on most (think Git, cloud platforms, scripting languages, databases, or the frameworks you use daily). • One or two brief examples of past work that prove you can move from requirement to working solution without hand-holding. • Your current availability (hours per week and time-zone overlap) and pre...

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 have not changed any system configurations nor applied any patches or updates before the failure occurred. I need an expert who can: • Diagnose and repair the AppFabric installation that underpins Distributed Cache. • Re-provision and bring the Distributed Cache service online so user profile synchronization works again. • Validate that cache hosts are correctly joined to the cluster and confirm no residual data loss or throttling issues remain. • Document the steps taken and any PowerShell commands used so I can replicate the fix in a disaster-recovery sce...

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. Here is what I need from you: • Transfer the entire plug-in and content folders to the external SSD, preserving file structure. • Update paths or create the necessary symbolic links so Logic Pro sees the libraries in their new home without any manual relinking on my part. • Verify every plug-in launches, scans, and passes the Logic Plug-in Manager validation once the move is finished. • Pr...

I need an experienced field engineer to spend a day on-site installing and bringing online new network hardware.

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. Your focus will be purely physical: racking and mounting Cisco, HP, and Dell switches, servers, and firewalls; dressing both power and copper/fiber runs neatly; then powering everything up so we can reach it remotely via the console or management ports. Once devices are live, you’ll run quick-hit checks—basic pings, uplink and printer connectivity, plus a test print from each printer—to be sure the new gear and the existing workstations all join the network without surprises. I will supply a clear, step-by-step build guide and remain online to answer questions in real time. Deliverables: • All specifi...

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 will supply SSH access to a fresh VM and either a Class 1/2 USB modem or a T.38 SIP trunk you can register against.

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. The VM must start up cleanly with the core modules I care about already active―Financial Accounting (FI), Material Management (MM), Sales & Distribution (SD), plus Controlling (CO), Production Planning (PP) and Warehouse Management (WM). The exact hypervisor is flexible. I have access to VMware Workstation, Hyper-V and VirtualBox, so we can pick whichever option will deliver the smoothest performance on my hardware. What I need from you • Verify my machine’s capacity and list any pre-installation tweaks. • Supply or point me to the correct trial media and developer licenses, then install S/4HANA inside the VM. &bu...

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. If you have already registered an Airtel SIP trunk on Linux, you’ll know the exact registrar format, the unusual port mapping Airtel uses, and the little tweaks that keep audio flowing both ways behind NAT. 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...

You will take full ownership of user account and license management, tighten security configurations, and create well-structured groups that make life easier across SharePoint, Teams, and OneDrive. Domain and DNS entries are already in place but may need a quick sanity check while you are inside the tenant. Because our staff relies on desktop sync, I also expect best-practice guidance to keep endpoints fast and healthy. Deliverables • User lifecycle streamlined: onboarding, offboarding, and changes captured as clear SOPs • Licenses optimised and auto-assignment rules (where poss...

Our core business platform still runs on Visual FoxPro 9.0 and, while it remains stable, new issues surface whenever data volumes spike or Windows updates roll out. I need an experienced VFP hand to step into the codebase, trace defects, optimise slow queries, and generally keep the application healthy so staff can work uninterrupted. Here’s how I see the engagement unfolding: • Diagnose and repair any runtime errors or data-related glitches we flag. • Streamline heavy reports and long-running SELECTs to improve performance against tables that now exceed several million rows. • Refactor screens or forms where legacy UI logic causes freezes or display problems under newer Windows builds. • Leave the code cleaner than you found it—comment your changes ...

I have an ESP32 based product that should maintain a steady Wi-Fi link, yet on my home network it keeps dropping off and taking too long to re-associate. Stability and reliability are my chief concerns; speed is acceptable once the board reconnects. The task is straightforward: go through the existing codebase, spot whatever is undermining the connection logic, and supply clear, working fixes. Serial logs, event callbacks, power-saving modes, and DHCP handling are all fair game—whatever it takes to stop the frequent disconnects. Deliverables • Annotated version of my original source showing every change made • A concise technical note explaining the root cause and the remedy (1–2 pages) • A quick reconnection stress-test script or steps I can replicate to p...

I need a turnkey deployment of ZoneMinder—or another equally dependable free or low-cost alternative—capable of monitoring dozens of NVRs and cameras distributed across multiple locations. The objective is to have an at-a-glance view confirming that every stream is live, recordings are being written properly, and storage pools remain healthy. Platform selection is flexible; Windows, Linux, or macOS are all acceptable, provided the final environment is stable, secure, and easy to maintain with regular updates. The key requirement is a web-based dashboard that presents real-time device status, allows deep dives into historical performance metrics, and generates fully customizable alerts whenever any parameter moves outside defined thresholds. Instead of integrating with an exte...

I need a custom-built screen-sharing application for Windows that feels as seamless as TeamViewer or AnyDesk but remains persistent even if the host user tries to remove or disable it. The service must install itself as a background process, automatically launch at every system start-up, and quietly reconnect without any manual action. Core capabilities I expect • Full remote-control of the host PC, including keyboard and mouse input, with smooth, real-time streaming. • Secure file transfer in both directions. • Single sign-on authentication so my team can log in with our existing identity provider rather than juggling extra passwords. Please focus only on Windows for the first release; 32- and 64-bit compatibility is required. Strong encryption, minimal latency, and...

My Linux server is ready, Laravel is in place, and I now need gblicense v15 fully installed, configured, and served through an Nginx reverse-proxy. Default gblicense settings are acceptable; the key requirement is that every feature runs smoothly behind the proxy without breaking existing Laravel routes. What you will do • Compile or obtain the correct gblicense v15 binaries, deploy them to the server, and wire them up to the current Laravel stack. • Configure Nginx as the single entry point, including HTTPS termination (certbot is already available) and clean routing so that gblicense runs on its intended port while remaining invisible to the end user. • Optimise basic network security inside the app and proxy layers (a separate firewall is not planned). • Tro...

I have an existing code-base that needs to be compiled, configured, and deployed on a CentOS 7 server. The stack spans several languages (the repository mixes Java, Python, a bit of C++, and some PHP utility scripts) so I need someone comfortable moving through polyglot projects without breaking stride. （Developed independently using a non-Java language） The immediate goal is a repeatable deployment: building the artefacts, resolving library dependencies, wiring in systemd service files, and validating that everything starts cleanly after a reboot. You’ll work directly on my CentOS 7 instance (SSH access provided) and document any package or kernel-level tweaks you make so I can reproduce the setup on staging and production later. Because the code also ships to a small cross-pla...

I have between two and ten new workstations that need to be taken from boxed parts to fully-operational machines. Every unit already has its CPU, motherboard, RAM, storage drives, graphics card, and standard peripherals on hand; I just need a reliable technician to install and configure them correctly. Once the hardware is in place I’d like you to load the operating system and the core software applications we use so that each computer boots straight into a ready-to-work environment. Driver updates, basic BIOS tweaks, and any firmware required for stability are expected as part of the job. The installation will take place on-site, and I’ll supply all components, licences, and network credentials. You bring the tools, know-how, and a methodical approach that leaves every machi...
