The Thetis Menu shows the following items:
- Restart Service: After clicking this menu item the provided service will be restarted completely. Your will be invisible in your client app and a “Searching …” label is shown.
- Check for Updates: Thetis searches for updates automatically after each start. Using this menu item you can start the searching manually.
- Preferences: The preferences are explained in detail below.
- Quit: Quits Thetis.
After clicking the item “Preferences …” a settings window opens which is divided into two sections:
In this pane you can select if Thetis shall be started automatically while launching your Mac. You should not change (deactivate) this setting or otherwise you have to start Thetis manually each time you need it.
The Connection type defines, if Thetis shall provide its availability using Bonjour throughout the network and enable devices to finde and connect to the Thetis service (for this, the Mac on which Thetis is currently running and the device have to belong to the same subnet) or if Thetis is silent and device have to use the IP address of the Mac Thetis is running on to connect.
Basically it is possible to limit the connection of client apps in different kinds. Thetis knows three levels of security which are passed through one after the other but can be skipped each:
1. The Check if a known device (client) wants to connect to Thetis.
2. The Check if a known app tries to connect to Thetis.
3. The Check if the passed passphrase is correct (a passphrase is a collection of characters, digits or special chars).
As said above, it is for example possible to precept Thetis not to validate a passphrase but to check if a known client device tries to connect.
The settings are:
- The precept that Thetis needs a valid passphrase.
- D chosen passphrase. Important: The passphrase is stored encrypted directly after closing the window. After this the passphrase can not be demanded in clear text. If a passphrase is stored yet can be seen by the placeholder text (grey) and if the strength indicator (s. ➌) shows a color.
- The strength indicator shall give you a hint if the given passphrase shows a reasonable strength. It should show “green”, otherwise the given passphrase is too weak. Secure and strong passphrases contain each upper case and lower case characters, digits and special chars. The length has an impact to the strength as well. In case you have selected a passphrase which could be too weak, Thetis shows a warning alert when leaving the window.
- The precept that the connection to Thetis shall be limited to certain clients (like your iPhone). Known clients are shown in the list ➏ and can be removed using the “-” symbol.
- The precept that the connection to Thetis shall be limited to certain apps (like iCody). Known apps are shown in the list ➐ and can be removed using the “-” symbol.
- The list of known devices (clients).
- The list of known apps.
- The precept if unknown clients shall be added to the list of known clients automatically when they try to connect to Thetis. In case this checkbox isn’t set Thetis will ask if this unknown client shall be added or not.
- The precept if unknown apps shall be added to the list of known apps automatically when they try to connect to Thetis. In case this checkbox isn’t set Thetis will ask if this unknown app shall be added or not.
The window will be closed and the settings are saved using the “OK” button. Clicking “Cancel” or closing the window will have no effect on your former settings.
