TurnKey Core is the base operating system which all TurnKey GNU/Linux solutions share in common. It is commonly deployed standalone as a convenient starting point for custom system integrations. Benefits include automatic daily security updates, 1-click backup and restore (TKLBAM), a web control panel (Webmin), and preconfigured system monitoring (Monit) with optional email alerts.

Features:

• Base Operating System: Debian GNU/Linux 'stable'.

• Build formats: Deploys on bare metal, virtual machines (e.g., OpenStack, VMWare, VirtualBox, LXC, KVM, Xen) and in the cloud.

  • ISO images: Generic installable Live CD. Installs anywhere.
  • Virtual Machine images: Optimized for virtualized hardware, pre-installed and ready to run.
  • Amazon Machine Image (AMI): Best launched via the TurnKey Hub.

• Free as in speech: free software with full source code and a powerful build system. Free of hidden backdoors, free from restrictive licensing and free to learn from, modify and distribute.

• Secure and easy to maintain: Auto-updated daily with latest Debian security patches. Optional monitoring and email notification of system alerts.

• 1-click backup and restore (TKLBAM): smart backup and data migration software saves changes to files, databases and package management to encrypted storage which a system can be automatically restored from.

• Dynamic DNS (HubDNS): Associates your IP with a custom domain or the free *.tklapp.com domain.

• Logical Volume Management (LVM): Instead of installing to a fixed size partition, a Logical Volume is first created by default, and this may later be expanded, even across multiple physical devices.

  • Listens on port 12321 (uses SSL).
