    I need a custom plugin for my self-hosted MeshCentral instance (running on Linux). The goal is simple: every user account should automatically deactivate on a date I pre-select, and I must be able to change that date at any time from the admin side. Key behaviour • When I create or edit a user, a date-picker field appears (ideally right inside the user’s account page). • On reaching the selected date, the account is disabled and the user can no longer log in. • A visible dashboard alert should start appearing for the admin seven days before expiry and remain until the account is disabled. No e-mail or other notification methods are needed. • Only the admin role needs access to set or edit the expiry date; regular users never see the picker. • The p...

    I had NordVPN running smoothly on my new Ubuntu laptop for the first few days, but after tweaking some network settings on the machine the VPN refuses to reconnect. I would like someone to: • diagnose what I changed in Ubuntu’s network stack that is blocking NordVPN, • put those settings back into a clean, working state (command-line or NetworkManager), • verify that my home router is forwarding traffic or configured correctly so the VPN handshake is not being blocked, and • give me a short walkthrough so I understand how to avoid breaking things again. The job covers both the laptop and the router. We can work over a screen-share or SSH, whichever you prefer, as long as you explain each step.

    After uploading a fresh set of files and reorganising the entire site structure on my Amazon Lightsail instance, every URL—including the homepage—now returns a 404. Nothing else on the server was changed, so I suspect the issue sits with the web-server configuration, .htaccess rules, or the Lightsail networking/DNS settings. Here’s what I need: • Diagnose why all pages are throwing 404s. • Correct the root cause—whether that’s a VirtualHost mis-match, missing index file, wrong document root, or rewrite rule conflict. • Verify the fix by showing the site loads normally over HTTP / HTTPS. • Send me a concise summary of what you changed so I can track it for future deployments.

Please document each step you take, note any reboots, and leave me with a short checklist for adding additional Domain Controllers later if required. Acceptance criteria • Server boots to a healthy DC with DNS and AD replica...

    I have the installer file for an older release of CrossOver and I need it set up properly on my Zorin OS 17.3 machine. The job covers the full installation process, including tracking down and configuring any 32-bit libraries, wine prefixes, or other dependencies the package expects so that the application launches cleanly and can open Windows programs without errors. I will provide: • The .deb or .bin installer file for the exact CrossOver build I want. • Remote access or screen-share at a mutually convenient time. What I need from you: 1. Verify system prerequisites and install any missing packages or i386 architecture libraries required by this legacy CrossOver version. 2. Run the installer and resolve conflicts that may appear with existing Wine or Flatpak versi...

    I already have a Contabo server standing by and simply need a clean, production-ready ViciDial stack on it. The job covers: • Installing the latest stable ViciDial (with Asterisk and its dependencies) from scratch. • Optimising the underlying Linux distro you feel is most reliable for call-centre workloads. • Hardening the box with a well-tested firewall configuration—CSF, UFW, iptables, or a similar solution is fine—as long as only the ports Vicidial, SSH and web administration actually require remain open. • Verifying that the web interface, database, and telephony services all start automatically after a reboot and that calls can be placed through a demo campaign. • Supplying a concise hand-off sheet: all commands run, credentials created, a...

    I need an experienced L2/L3-level Citrix administrator who can take full ownership of system upgrades and patching for our Citrix Virtual Apps and Desktops environment. The role is fully remote; I will provide secure access to the delivery controllers, VDAs and supporting infrastructure so you can work during mutually agreed maintenance windows. Your main focus will be to keep the farm current and stable—planning each upgrade, backing up and snapshotting the environment, applying Citrix–recommended hotfixes, testing for regression, then handing it back to operations with clear rollback documentation. Because this is an active production environment, you must already be comfortable with version dependencies, Licensing Server compatibility, SQL mirror considerations and StoreFro...

    My VPS on Hostinger’s KVM line has started to crawl and I can’t pinpoint why. I’m looking for someone who already knows their way around the Hostinger panel, KVM virtualization, and typical Linux performance-tuning tools to jump in, diagnose the bottlenecks, and restore normal speed. Scope • This is strictly troubleshooting and ongoing maintenance; the server is already live. • The main pain point is degraded performance—slow response times under even light traffic. No connection drops or software errors have shown up, only sluggishness. • I need action right away, so please be ready to begin as soon as access is granted. Deliverables - A clear diagnosis of the root cause (CPU, I/O, memory, network, misconfiguration, etc.). - Applied fixes...

    I run a custom web application on an Ubuntu droplet at DigitalOcean. Although every obvious door is locked—UFW rules are strict, all unnecessary ports are closed, Fail2ban is active, and SSH keys have been rotated—crypto-miners keep finding a way in and even wiping my authorized_keys file. and they also remove the logs. I need a specialist who can dig deeper than the basics, trace exactly how the breaches occur, close those vectors for good, and leave the box fully hardened. Think kernel-level auditing, service isolation, intrusion-detection tooling, automated patching, and any other best practices you know work on Ubuntu in a cloud-VM context. Deliverables I must see before sign-off: • A concise report pinpointing the original compromise path(s) and the corrective...

    I need help getting a working simulator of the Utimaco Atalla AT1000 Payment HSM up and running so my team can prototype against it before we commit to physical hardware. If you have direct experience installing, licensing, or configuring this specific simulator, I’d like you to: • Supply or point me to the correct, up-to-date installer and any mandatory libraries. • Walk me through the complete setup on a clean virtual machine (Windows Server or Linux—whichever you feel is smoother). • Verify that standard commands for PIN block translation, key import/export, and EMV transaction scripts all execute without errors. • Hand over a brief usage guide outlining start-up, shutdown, and basic test commands so my developers can continue on their own. A shor...

    I run a FreeBSD mail server that uses Dovecot for IMAP. I’m ready to retire that box and move everything— emails only, no contacts or calendars— into Microsoft 365. 10 active mailboxes need to make the jump. Here’s what I need from you: plan the cut-over, copy every message into the correct Microsoft 365 mailbox, and leave me with a clean, documented switchover that keeps downtime to an absolute minimum. I will handle the licensing on the Microsoft side and any DNS or MX tweak and verification that each user can sign in and see a complete, intact mailbox.. You handle the data moves. Deliverable summary: • All emails replicated for every account • Guidance on DNS/MX records updating and propagating • Assistance with post-migration validation ...
