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 an experienced Cisco UC engineer to move our entire Cisco Unified Communications Manager 11.5 cluster from the current pair of UCS servers to a fresh BE6K-M6-K9 platform. The goal is a like-for-like migration: two nodes in an active / passive arrangement, keeping every dial plan entry, device pool, SRST reference, certificate, and license exactly as they are today. I’m looking for full, end-to-end assistance. That includes planning the cut-over, exporting and restoring the DRS backup (or using Prime Collaboration Deployment if that proves cleaner), rebuilding the cluster on the BE6K hardware, and validating that phones, trunks, voicemail integrations, and presence services all register with zero loss of service. The passive node must mirror the current HA behaviour; no new ba...

I'm seeking an IT professional to set up and manage a Local Area Network (LAN) in my office. The network will need to connect multiple devices including 3 computers, 2 printers, and 2 VOIP phones. Ethernet cable may be needed but office may already be wired to existing outlets. Key tasks include: - Configure network hardware (routers, switches) - Set up IP addresses and subnetting - Ensure secure and reliable connectivity - Connect and test all devices (computers, printers, VOIP phones) - Provide documentation for network setup Ideal Skills & Experience: - Proven experience in LAN setup and management - Strong understanding of network protocols and hardware - Familiarity with VOIP integration - Excellent troubleshooting skills - Relevant certifications (CCNA, CompTIA Network+) a...

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...

This project establishes a completely new Aruba-based LAN and wireless infrastructure for our corporate headquarters, designed to serve between 100 and 500 employees from day one while leaving room for future growth. Scope of Work • Produce a detailed architecture that combines Aruba CX access/core switches, campus access points, and Mobility Conductors / Controllers. • Map out VLANs, routing, QoS and PoE budgets, ensuring seamless wired-to-wireless roaming. • Create an RF plan that balances coverage and capacity across open areas, meeting rooms and executive suites. • Develop configuration templates (AOS-CX & AOS-10/AOS-8 as appropriate) and switch/router/controller startup configs. • Integrate with existing services such as DHCP, RADIUS/AD and gues...

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

I have a GL-iNet Beryl (AX) running in tandem with an Opal that should be blanketing my apartment here in Montréal, yet speeds crawl well below what my cable line delivers. Everything is physically connected, the routers see the WAN, and basic resets, firmware checks, and channel swaps have already been done. I’m looking for someone who can come on-site, dig deeper into the settings, and leave me with a rock-solid, high-throughput home network. You’ll need to analyse the cable modem hand-off, confirm the Beryl’s WAN/LAN configuration, fine-tune wireless parameters on both units, and verify performance room-to-room before you wrap up. A short report of the final settings and the speed test results will be the hand-over so I can keep things stable after you leave. ...
