Please Wait. |

| System Reboot & Operating System Updates | |
|---|---|
| Once the installation process has completed, Snare Central will automatically reboot. At this point, specific components required for the operation of the event collection, analysis and reporting environment, will be installed; as will security updates to the baseline packages that come with the installation media. This process should take approximately 15 minutes to complete, depending on the number of updates included. The most recent line from the raw output from the package update process, will be displayed within the dialog window. The initial boot process may take around 20-30 seconds the first time through. |
| Operating System Package Configuration | |
|---|---|
| The installation process will return to the console in order to configure key operating system packages, just in case a package requires user input in order to continue the installation process. Please wait. |
| Snare Central Bootstrap | |
|---|---|
| Several server-specific tasks will scroll through, including the installation and configuration of configuration databases, the installation of administrative objectives, and the initialisation of firewall rule sets. Please wait. |
| Administrator Password | |
|---|---|
| An initial password for the "Administrator" account for the Snare Central web interface, will be generated, set, and displayed. The password will be chosen from random alpha-numeric characters, be 10 characters in length, and will exclude look-alike characters such as O/0 and I/l. To update this password post-installation, refer to Knowledge Base article at https://support.prophecyinternational.com/s/article/How - to - reset - the - administrator - password - for - Snare -Central Server. Please note this password for future reference. |

|---|---|
| Snare Central needs to reboot one last time at the completion of the installation process, to complete the upgrade process of system packages. Press Enter to reboot. The Server will briefly return you to a black console, while finalising the installation process. If you are on a VMWare client, with a virtual floppy-drive installed, you may see I/O errors relating to 'fd0' - these are normal and safe to ignore. Other warning messages may be displayed on the console - this are also safe to ignore, and are anticipated & rectified as part of the modified installation process. |
