    My current VPS has been compromised and I need to relocate the entire site—including all files, a MariaDB database, and its DNS server setup—to a fresh, hardened Ubuntu box. We will work side-by-side in real time over Zoom with shared screen; no unattended access will be granted. What you’ll be helping me do • OPTIONAL - Audit the existing Apache2 + php-fpm stack, vBulletin 5/6 installation, and Webmin settings to confirm the scope of infection. • Package and move every site asset and the MariaDB dump to the new host. • CREATE NEW MASTER DNS FROM ANOTHER DNS - Re-create DNS records and verify propagation. • Lock down the new server with best-practice hardening (firewall, SSH, permissions, fail2ban, etc.) so the forum is protected against both ...

    I am moving our production DNS from a Windows-based server to a fresh Debian instance running Bind9. The new host needs to be fully authoritative for all current zones, so I will rely on you to extract every record from the Windows server, import them into Bind-compatible zone files, and validate that the answers match bit-for-bit before cut-over. Once the zones are in place, I also want DNSSEC enabled with a properly generated Key Signing Key (KSK) and Zone Signing Key (ZSK) for each zone. Please configure automatic key rollover and publish the DS records I will provide to my registrar. The goal is a seamless switchover with zero client disruption and clean validation on tools like dig +dnssec, dnsviz, and Verisign’s DNSSEC debugger. Deliverables • Debian 12 server with Bind9...

    A fresh AlmaLinux 10 server is waiting to be transformed into a production-ready shared-hosting node. The work starts with clean installs of cPanel/WHM, LiteSpeed Web Server, and CloudLinux, followed by enabling WHM’s reseller features and deploying WHMCS for automated billing and provisioning. After the installs, create the actual hosting packages inside WHM and replicate them in WHMCS so new orders are pushed straight to the server without manual intervention. Please deliver the job fully configured, security-hardened, and performance-tuned, then run a test signup to prove that WHMCS, WHM, and LiteSpeed are talking to each other correctly.

    Unlimited SMTP Setup on cPanel

    I need a fresh SMTP server configured and fully integrated with my existing cPanel account so I can push roughly 1 000–10 000 emails per day through Webmail without bumping into the usual sending limits. There is no current SMTP service in place, so the job starts from scratch: provisioning the server, linking it to my domain inside cPanel, and making sure every authentication layer—SPF, DKIM, DMARC, rDNS—is properly applied for strong inbox placement. Once it is live, I want to be able to open Roundcube (or any default Webmail client that ships with cPanel) and send campaigns confidently, knowing throttling is no longer an issue. Please secure the server, tweak Exim or Postfix for high-volume performance, and leave me with clear, concise notes on how to add future domai...

    Complete MailWizz Server Setup

    I already own the domain; now I need a fully-operational MailWizz environment that I can start using the moment you hand it over. You will supply and configure everything—dedicated Windows server, clean IP address, valid MailWizz license, and any underlying mail transfer agent—so I don’t have to purchase additional components or subscriptions. The build must be optimised for high-volume transactional emails. Rather than relying on third-party relays like Amazon SES, SendGrid, or Mailgun, I’d like to send directly through MailWizz itself, so please install and tune the SMTP/MTA you feel delivers the best inbox placement on a Windows stack. Key deliverables: • Provisioning of a Windows server with a fresh IP • Installation and activation of MailWizz unde...
