The main function of the RT-Nagios gateway is to transform specific alerts from Nagios into a Help Desk ticket in Request Tracker to help your compliance efforts for incident responses (and other items) under ISO27001, SOX, and others. This provides better reporting, resource management, and more. Nagios configuration determines which incidents will generate tickets in RT. The URL of the ticket is inserted into the comment field of the corresponding Nagios service. The interface is bi-directional: when a user is "taking" charge of the ticket in RT, an acknowledgement for that service is sent to Nagios, stopping the alerts. Multiple alerts from a specific incident are "merged" within the original ticket.

Whonix is an anonymous general-purpose operating system based on Virtual Box, Debian GNU/Linux, and Tor. By design, IP and DNS leaks are impossible. Not even malware with root rights can find out the user's real IP/location, because Whonix consists of two (virtual) machines. One machine solely runs Tor and acts as a gateway, called Whonix-Gateway. The other machine, Whonix-Workstation, is on a completely isolated network. Only connections through Tor are possible.
