At this stage nothing has been provisioned, so I need someone who knows their way around the Leaseweb control panel to walk me through the complete setup, spin up the first server, apply sensible security hardening, and leave me with clear notes on what was done and why. Typical touch-points will include picking the right plan, deploying an instance, setting up user access, SSH / RDP configuration, firewall rules, monitoring basics, and any tweaks you consider best practice for performance and reliability. I’m open to either Windows or Linux images, so your recommendation here will be welcome. The job is primarily about the initial se...
I need help securing a single Windows server with Acronis. I’m open to either setting up a brand-new Acronis backup or reactivating the former installation—whichever you determine is faster and more reliable. Scope of work • Confirm licence status and evaluate whether re-activating the former Acronis instance is viable or if a clean install is the better route. • Configure daily backups that cover: – Files and folders – Applications and databases – Entire system image • Validate that recovery points are usable by performing at least one test restore. • Document the final configuration (schedule, retention policy, storage location) so I can maintain it going forward. I will provide remote access details and any existing A...
My home network already runs on pfSense, but I need an experienced hand to tune it properly. The immediate priorities are: • Firewall rules – I want clear, maintainable rules that explicitly allow only the traffic I specify while leaving everything else untouched. • WireGuard VPN – configure the tunnel, keys, and routing so that remote devices can reach the LAN securely. • Traffic shaping – optimise bandwidth usage and prioritise latency-sensitive traffic. Everything should be implemented directly in the pfSense GUI, with inline comments or descriptive labels so I can understand and adjust settings later. I’ll provide current backups and remote access to the dashboard for the session. At the end I expect an updated config file plus a short chang...

I need a complete, self-hosted email solution for a small business that I’ll be running on a Linux server (Ubuntu or CentOS—whichever you feel is best for the chosen stack). The key objective is to move away from third-party providers and gain full control over our mail, security, and data compliance. The specific mail-transfer agent is still open: Postfix, Exim, Mailcow or another proven alternative can be used, as long as the end result is stable, secure, and straightforward to maintain. What I expect from you: • A production-ready mail server configured with SMTP, IMAP/POP3, spam and virus filtering, DKIM, SPF, DMARC, and valid SSL/TLS certificates. • Simple webmail access and clear instructions so that I can add domains, users, and aliases without touching...

I keep getting the message “The action cannot be completed because the other program is busy” on my Windows machine and it’s driving me crazy. The alert pops up constantly—there’s no single app I can link it to—so I need someone who can dig in, trace the root cause, and stop it for good. You’ll have remote access to the computer to run diagnostics, inspect event logs, check for stuck COM or DDE calls, and rule out background services or conflicting startup items. Once the culprit is identified, I expect the fix applied, a short summary of what was wrong, and clear steps I can follow if it ever re-appears. Deliverables • Root-cause report (brief but specific) • Applied fix with confirmation the alert no longer appears after a reasona...

I need someone to bring my Oracle 11g server online and make sure it starts cleanly every time my Red Hat Enterprise Linux machine boots. The software is already on the box; what’s missing is a reliable, Standard installation-style configuration that finishes the setup, starts the database, confirms the listener is running, and registers the instance correctly with systemd so it survives reboots. You’ll connect over SSH, verify the existing Oracle home, adjust any kernel parameters or environment variables that were skipped, and walk me through the key commands so I understand how to start and stop the service myself. A simple set of notes or a shell script showing the steps you performed is all I need as a final hand-off.

My production WordPress site running on AWS has suddenly gone offline and I need it restored to its last stable state as quickly as possible. The incident presents itself as a full website crash, so visitors currently see either a blank page or an error message. The stack is a typical EC2 + RDS (MariaDB) setup behind an Application Load Balancer, with nightly EBS snapshots enabled and AWS Backup configured—yet I have not confirmed which recovery point will be safest to use. I need someone who can immediately jump in, locate the most recent valid snapshot or other backup, perform the rollback, and verify that the site loads normally over HTTPS once complete. A successful engagement will: • Restore the site so pages, media files, and database content appear exactly as they...
U.S. based freelancers only. I need a sworn declaration from a digital forensics or email systems expert for use in a legal arbitration. The Declaration will be used in a California arbitration, so the expert must be located in the United States. Preference for professionals with experience administering Microsoft Outlook/Microsoft 365/Exchange email systems. The issue concerns production of emails from a law firm that uses Microsoft Outlook. The firm has my client file emails but is resisting producing them in PST format, claiming that doing so could expose other clients’ emails. The declaration should confirm: • PST is the standard format used by Microsoft Outlook for storing and exporting email • Emails can be exported into a PST from a defined set of messages (suc...
I’m running a self-hosted MeshCentral server on Ubuntu 24 Linux and I need two equally important improvements added to its web interface. 1) Per-user concurrent-session cap From the UI I want to be able to enter a number that represents the maximum simultaneous device connections or remote sessions a given user can open. Once that threshold is reached, additional connection attempts must be blocked until an existing session ends. The setting must work on a per-user basis without impacting other users or global server limits. 2) Account expiry date control I also need a date picker in the user–edit screen that lets me set an explicit expiry date for an account. When that day arrives the account should become disabled automatically, with no manual cleanup required. An a...
I’m running Zorin OS and I need Office 2016 up and working through a legacy build of CodeWeavers Crossover that I already have on hand. The Office 2016 installers are also ready to go. Your task is to: • Cleanly install this specific, older Crossover release on my current Zorin system without breaking existing packages. • Configure the correct Windows bottle, apply any tweaks or winetricks required, and complete the Office 2016 setup so every application in the suite launches, activates and updates normally. • Provide a brief, step-by-step text summary of what you did so I can replicate the process later if I reinstall. I’ve successfully installed Crossover on Zorin before, so you’ll be working on a familiar environment; I just need expert help pinni...
I need a Windows specialist to help me regain full access to a folder of images and other files that sits on an external drive. After restricting permissions on Windows 10 for privacy, I upgraded to Windows 11, ran into performance issues, then rolled back to Windows 10 through a clean install. Since that reinstall, any attempt to open files in this particular folder throws a “You don’t have permission” error—even after I thought I had fixed similar wallpaper-related permission problems. The task is straightforward: reset or repair the file and folder permissions on that external drive so I can read, edit, and move every item inside without errors. All work will be done over a remote session; once you finish, I’ll verify the files open normally and the permis...
My Supabase-backed web application needs a solid, automated maintenance routine. The core of the project is to keep the database healthy and fast, so I want complete coverage for three areas: regular backup and reliable recovery paths, performance tuning that actually shaves time off the heavier queries, and a clean workflow for applying Supabase/PostgreSQL updates and security patches without downtime. I already have the project running on Supabase; what’s missing is the living set of scripts, schedules, and monitoring rules that turn ad-hoc admin work into a predictable process. You’ll work directly in Supabase (and the underlying Postgres layer) and can bring in any complementary tooling—pg_dump, cron, pgBouncer, Grafana, or similar—as long as it integrates smoo...
I’m looking for someone who can get the Scan-to-Folder function working on a Ricoh Aficio MP C2800 that’s already networked and printing fine to a Windows PC. The goal is simple: every time we scan, the machine should drop a single PDF into a shared folder on our local network that all staff can reach. You’ll need to create or verify the Windows SMB share, adjust permissions, enter the correct path and credentials through the device’s Web Image Monitor, then test from the copier’s panel to prove that multi-page documents arrive as one consolidated PDF. Deliverables • Full configuration of Scan-to-Folder on the Ricoh MP C2800 • Verified Windows shared folder with proper access rights • Address-book shortcut on the copier for one-touch...

Once everything is installed, demonstrate basic tasks—creating a user, uploading a file, restoring from backup, and logging in/out—so I know the setup is solid. If you’ve handled OpenClaw or similar self-hosted platforms on Windows before, especially with custom folder topologies or automated backup scripts, I’d love to hear how you’d appro...
I need to move my Hetzner server to a fresh operating system and, at the same time, bring the Plesk-managed PHP version up to date. The machine currently hosts one site and all associated mailboxes, so zero data loss is non-negotiable. Because the server is used primarily for web hosting, I’m open to Ubuntu, CentOS, or Debian and would like your recommendation on which distro will give the most stable, long-term support for Plesk and modern PHP versions. Once we agree on that choice, I’ll schedule the migration window. What has to happen: • Create a full, verifiable backup of every website, database, and mailbox. • Rebuild or reinstall the server with the chosen OS at Hetzner. • Re-install or migrate Plesk, configure the latest stable PHP version, and restore a...

I need an IPRN switch brought online fast, fully wired for billing integration and ready to carry live traffic. The core signalling will run over SIP, so every module you build or configure must interoperate cleanly with SIP endpoints and the upstream carrier trunks I already have in place. Billing is the priority: once a call lands on the switch the CDRs must flow straight into our existing rating platform without manual touches. I am open to whether you plug in a ready-made mediation layer or write custom logic—what matters is that usage records appear in real time and reconcile correctly at the end of each day. You will get SSH access to a fresh cloud instance plus the credential set for my billing server. I expect you to: • Deploy or compile the soft-switch software, enab...

I am looking for secure, temporary access to a live Sage X3 V12 Command Line Interface that I can reach remotely. My immediate need is to run Data migration jobs, Automating reports and a few Custom script execution scenarios inside a dedicated Testing environment. The CLI must expose the Finance and Inventory modules so I can validate scripts against real tables and standard functions. A standalone app or jump-box style VM is fine, provided it already has the V12 runtimes and the usual X3 utilities pre-configured. Deliverables I expect: • Connection details (host, port, user, password or key) with any VPN instructions • Confirmation that the Finance and Inventory folders are available and compile cleanly • Ability to launch the CLI and run a sample data-load, a ...
I have a working script that only finishes when it can grab more than 100 GB of RAM. Right now I keep it online by renting several VPS instances, which already drains well over $500 every month and still doesn’t let me scale efficiently when workload spikes. I’m absolutely open to revisiting the way the program uses resources. What I need first is a sharp mind that can study the current setup, pinpoint where memory is wasted, and outline a smarter resource-management strategy. Whether the answer ends up being sharding the job across nodes, streaming data in smaller chunks, redesigning the in-memory structures, or off-loading parts to a managed cloud service, I’m ready to explore it—as long as we end up with a solution that scales without blowing up the budget. ...

I have a fresh Windows Server 2012 machine reachable over RDP that must become the primary Domain Controller for a small office network. The core need is straightforward server setup and configuration: install the AD DS role, configure DNS on the same host, assign a static IP, create the new forest and domain, and apply a few baseline Group Policies (password length, lockout thresholds, and time sync). Once the promotion is complete, I’ll need at least one administrator account and two test user accounts created so I can verify logon from client PCs. 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.

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.

This project centres on a clean rack-and-stack of new IT gear in our data room. I will supply detailed rack elevations and network diagrams beforehand; once you arrive, the job is entirely hands-on: • Mount the servers, switches, firewalls and routers in the designated cabinets. • Dress and terminate all power and data cabling, keeping airflow and service-loops in mind. • Attach and label console leads so my remote team can reach each device immediately. • Power-on, verify link lights, and run basic connectivity checks, noting any issues that need escalation.

I already hold an active Google Workspace subscription but haven’t connected it to my domain, which is managed by another provider. I’d like your help to: • Verify and connect the domain to Google Workspace, updating the required MX, SPF, DKIM and DMARC records at my registrar. • Configure a single mailbox as a trial run and migrate the contents of that one existing account so I can confirm everything works before we move more users.
