My office relies heavily on a mixed environment of Windows workstations and a growing fleet of Ubuntu machines, so day-to-day stability is critical. I need someone who can drop straight into real-world troubleshooting—swapping out failing laptop drives, cleaning up driver issues, reinstalling an OS when it is faster than patching, and keeping every system fully-patched and backed up. The immediate priority is our Ubuntu-based infrastructure: fresh server installations, user management, and routine CLI-level administration. Alongside this, I have several hardware firewalls that must be given a clean, BASIC setup—standard rules, NAT, limited port exposure, and a sanity check on default credentials. Networking touches almost every ticket that crosses my desk. You will be the...

I’m sourcing ready-to-install operating-system images for Windows, Linux and ChromeOS. For Windows, the build must arrive fully activated; for Linux and ChromeOS I just need clean, production-ready images. In most cases I’ll ask for the current stable release, but I occasionally need an older build, so the ability to deliver either version on request is important. Every image should boot straight into the installer from ISO or USB and ship with a modern web browser pre-installed—nothing else. Supply links or cloud storage I can access immediately after payment. If a Windows activation key is required, include it and confirm that activation survives re-installation. Deliverables (per request): • Download link or drive image (ISO/IMG) for the specified OS and v...

Project Description: We are seeking an agile, highly disciplined DevOps engineer to execute a clean, streamlined mail infrastructure deployment on a freshly provisioned bare-metal Linux environment. This is a highly focused task requiring technical precision under a lean, execution-focused framework. Technical Scope of Work: • OS & Kernel Optimization: Perform initial hardening on a clean Ubuntu 22.04 LTS minimal net-install. Activate kernel BBR congestion control and optimize system file descriptors (nofile limits up to 65535) to handle concurrent high-volume outbound threads. • Network & Subnet Mapping: Configure a routed, contiguous /28 IPv4 network block via Netplan. Statically alias the usable IP footprint sequentially to align with our predefined enterprise reve...

I’m outfitting a new office with a Local Area Network whose main job is rapid, reliable data storage and access. All workstations—desktops and laptops—must connect seamlessly to a central NAS array, while network-ready printers and scanners stay reachable without slowing file transfers. Here’s what I’m after: • A clean LAN design that maps ports, switch hierarchy, and cabling so future expansion is painless. • Hardware and software configuration—switches, access points if needed, and the NAS itself—tuned for high throughput and low contention. • User-friendly shared folders with the right permission sets, keeping sensitive data protected yet easy to reach. • Printer/scanner integration so every machine can discover and us...

I need a small-scale VPN set up for one user to reach our Office 365 environment even when Microsoft’s regional limits (limited to scandinavia) get in the way. The sole aim is to bypass geographical restrictions for using work office 365 chat, viedeo and email in e.g. Europe and Moscow connect from Windows PCs only, so you can focus on that platform . I’m open to whichever VPN solution you consider the most reliable—WireGuard, OpenVPN, IPSec, or a cloud-based alternative—as long as it remains cost-effective and easy for non-technical staff to launch on demand. I had a try with GL.iNet-router and nordVPN without sucess. I do not have admin rights to my work pc. I consider if it is possible use mobile with network towards scandinavia as an alternative, but think ...

I need an experienced Windows troubleshooter who can jump in right now, connect remotely, and get my system back to normal.

Our Sendmail server has been relaying mail through Office 365 for years without a hiccup, but as of today every outbound message fails with the log entry “stat=User unknown.” Nothing on the system was recently patched or reconfigured, so I need a Sendmail-and-Exchange-Online specialist to step in, trace the fault, and restore normal delivery. Key areas that will probably require inspection include the local / settings, SMTP relay authentication, our Office 365 connector, TLS handshake parameters, any IP or domain blocks, DNS records and, of course, the mail logs on both sides. I can supply full SSH access to the mail host plus the Microsoft 365 admin portal and message trace results. Deliverables (acceptance criteria): • Identify the root cause and document it briefl...

I need a network-savvy engineer to build and fine-tune a private WireGuard VPN that lets me stream my home content library from abroad without tripping any geo-blocks. The connection must work flawlessly on my desktop and laptop, my iOS/Android phones, and a smart-TV/streaming box in the living room, so the configuration should cover multiple device profiles. Security is just as important as unblocking: a reliable kill switch and solid DNS-leak protection have to be baked in from the start. I’m open to your preferred way of achieving this—iptables rules, OS-level scripting, or an external firewall—but the end result must automatically cut traffic the moment the tunnel drops and make sure every DNS request stays inside the VPN. Because it’s a residential setup, I&r...

Basically i want to retrieve password of an realvnc username that has been recently changed by server.

I rely on daily remote backups of my OneDrive for data security, yet the built-in backup option keeps failing and no files are copied. I need a reliable, fully automated solution that completes successfully every day without manual intervention on my VPS I Have access to ssh.

I've attached the project PDF. It needs to be in Spanish and playable on an Android console (RetroidPocket 5) emulated with Nethersx2 Turnip. Please review the file and let me know if you can do would be good to have a .CHD file, but if that's not possible, an .iso file will do. The ISO version is in the document; I don't have any mod tools/files. The database is based on the 2005/2006 season. For the graphics, "PS2 Authentic" visuals are fine.

My immediate goal is to get a brand-new VPS up and running on Amazon EC2. The primary task is server setup and configuration; I’m not focusing on security hardening or ongoing maintenance right now—just a clean, reliable build that I can start using straight away. I’ve marked “AWS” as my operating-system preference and will be spinning this on EC2, so every step should align with AWS best practices—from choosing the right AMI to configuring networking, storage, and user access. If you have a preferred AWS-flavoured Linux distribution that streamlines future updates, feel free to recommend it as part of the setup. Deliverables • Launch and configure the EC2 instance in my AWS account • Apply initial OS settings (hostname, users, SSH, time zo...
