Administrator sistem 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 fresh Ubuntu 22.04 VPS ready and I want a fully working Open Tibia server running version 13.x or newer. I am happy to go with either Canary or TFS—whichever you feel will get us to a stable, live server fastest. My own attempts stalled mainly at the client-connection stage, so the critical piece for me is having at least one client (official Tibia or OTClient, I am flexible) connect reliably to the server once it is online. What I need from you: • Compile or install the chosen engine on the VPS, configure it, and verify it boots without errors. • Walk me through the minimal config changes so I understand what was done. • Provide a working client package—or clear instructions for obtaining and patching one—that logs straight into the serve...

I have a fresh Ubuntu server ready for a clean, secure Nextcloud deployment. I need the latest stable release installed, served over HTTPS with Let’s Encrypt, and the system hardened with sensible measures such as UFW and Fail2ban. Data should live on a separate mounted volume and the whole stack must update and back up automatically. If you are comfortable layering in popular office suites like Collabora Online or OnlyOffice later, mention that—those may become follow-up milestones once the core install is solid. Deliverables • Fully working Nextcloud instance reachable at my domain via TLS • One administrator account delivered to me securely • Clear, copy-pasteable documentation (or an Ansible/compose file) so I can repeat or restore the setup anytime ...

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.

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 operate two offices and I purchased two UniFi UDM Pro, and I want them linked so that staff can reach internal resources from either location as if they were on the same LAN or to work remotely (VPN access). Nothing is in place yet, so the full security stack must be designed and deployed from scratch. Scope of work • Build and test a site-to-site VPN between the two UDM Pros for seamless remote access. • Create granular firewall rules that allow only the traffic we specify while blocking everything else. • Enable and tune UniFi’s intrusion-detection/prevention features to catch unwanted activity without flooding us with false alarms. • Document every setting—screenshots or exported configs—so I can replicate or restore the setup if needed. ...

I’m running Ubuntu Server 22.04 on a Hostinger VPS and need a clean, dependable way to spin up Cal.com. Docker is not installed yet, so the first step is to get the latest Docker Engine and Docker Compose up and running with their default settings. Once Docker is active, I’d like you to: • Pull the official image (or build from source if that is the current best practice). • Launch the container so it auto-restarts and survives server reboots. • Expose the required ports and, if it simplifies access, wire it to an Nginx reverse proxy so the calendar sits behind my existing domain or a sub-domain. • Hand over the exact commands, configuration files, and environment variables you used, commented clearly so I can reproduce or tweak them later. I&rsquo...

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...

I need a Godaddy-issued SSL certificate installed and fully configured on my Windows Server 2019 VPS that is also hosted with Godaddy. The certificate has already been purchased; what’s left is generating the CSR (if you prefer, I can supply one), importing the returned certs, installing the intermediate chain, and binding everything to the correct IIS site so the domain loads only over HTTPS. Once the certificate is in place, please force-redirect all HTTP traffic to HTTPS, check for mixed-content warnings, and run an SSL Labs test to confirm an “A” rating or better. Deliverables • CSR generation (or validation of my existing CSR) • SSL certificate and chain correctly installed in IIS • HTTP-to-HTTPS redirect enabled and verified • Final rep...

I have completed a desktop application with Lovble IA and pushed the code to a GitHub repository. Now I need it running smoothly on my own Linux server. Your job is to pull the repo, set up whatever build or runtime environment Lovble IA requires, resolve any package or dependency issues, and make sure the executable starts up reliably (ideally as a service so it can restart after reboots). The repository is ready for cloning; you will receive access as soon as we start. I expect the finished application to launch without errors from the server’s command line or through an appropriate display manager, and I’d like brief notes on every step you take so I can replicate or update the deployment later. Deliverables • Working installation of the Lovble IA desktop app on my Li...

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 moving our entire virtual infrastructure from VMware vCenter to Proxmox VE, with hardware split between two sites—Miami and Tampa. The work is intentionally staged: Phase 1: Home-lab proof of concept A compact Proxmox cluster will be stood up in my lab, then loaded with a handful of representative VMs. Stability is the single most important measure here; the cluster must stay up, handle live migrations, run backups, and survive node reboots without dropping workloads. Clear documentation of the build and any tweaks you make is expected so I can reproduce the setup if needed. Phase 2: Production roll-out Once the lab proves rock-solid, we replicate the design in both datacenters. The end goal is better management—specifically, a single pane of glass that centrali...
