The TrutzBox® will now make your Internet more secure. It has the effect that you cannot be observed while e-mailing and cannot be spied on while surfing. You leave fewer traces on the Internet and you are less traceable. With the TrutzBox ® you strengthen your privacy.
The TrutzBox® is the security center of your home network. It controls incoming and outgoing Internet traffic. With the TrutzBox® you determine which information the devices connected to the Internet in your home network may disclose.
With the TrutzBox® you can control the Internet connections of your
- Internet devices at home, like computers, tablets, smartphones,
- mobile Internet devices on the move, such as laptops, tablets, smartphones,
- Internet-enabled devices, such as television, house control (e.g. roller shutters, heating), toothbrush, refrigerator, etc.
The TrutzBox® will make the lives of criminal Internet hackers, professional data traders and secret services, which have been observing you while surfing and use your data for their own purposes or commercially, more difficult to a previously unknown extent.
Comidio TrutzBox® offers optimal protection of your privacy through
- automatic end-to-end encryption of your e-mails,
- traceless surfing the Internet,
- maximum protection for your children,
- Firewall and virus protection,
- easy operability,
- cost-effective use,
and thus delivers optimal anonymity.
The TrutzBox® offers plug and play settings and is already optimally configured for most requirements at the factory. Special personal requirements are set via the easy-to-use user interface.

1.4 TrutzBox with or without (own) WLAN?
The WLAN module of the TrutzBox is required if a mobile device is to be controlled via the TrutzBox®. This is then connected directly to the network of the TrutzBox (= its WLAN).
There are basically two ways to connect devices to the TrutzBox®:
| Case 1: | PC 1 is connected to the Internet router via WLAN or network cable (dashed yellow).
|
| Case 2: | PC 2 is connected to the TrutzBox® via WLAN or network cable (green dashed). All Internet traffic (surfing) automatically passes through the TrutzBox®.This mode is called |
To use the TrutzBrowse and TrutzContent functions (secure surfing for and protection of minors), it can be decided for each device whether it should be left on the network of the Internet router (e.g. Fritzbox) (proxy mode) or connected to the TrutzBox network (transparent mode).
The aim is to connect as many or all devices as possible in the home network directly via the TrutzBox® (i.e. in "transparent mode").
It is advisable to reach this state step by step.
Therefore, you should start "small" at the beginning and gain experience in "proxy mode" by not changing anything on your home network, i.e. the devices initially remain on the Internet router.
You can also intentionally surf in a browser (e.g. Firefox) in proxy mode while surfing in parallel in a second browser (e.g. Chrome) without protection.
For example, you can track the influence the security slider has on unprotected access in various positions (e.g. effects on advertising offers shown).
If you have sufficient experience in proxy mode and would like to gain additional security, you can gradually connect devices in transparent mode by connecting them directly to the TrutzBox® via WLAN (or network cable).
[Since there are occasional exceptions in which website use is not possible even with SliderLevel 10 (TrutzBox set to "pull-through"), it is recommended to operate a browser-based client device in proxy mode, so that the TrutzBox can be switched off as a proxy in the browser of this client device if necessary. This allows the browser of this device to access the Internet directly via the Internet router (bypassing the TrutzBox). After the exception has been made, the TrutzBox should be activated again in the browser as a proxy].
This means that the TrutzBox can also be operated safely without a WLAN module and the WLAN module can be added later if required.
The other TrutzBox functions, such as Webmeeting, Mail, Chat and Remote Access, work in both modes unaffected by this.
To change from transparent mode to proxy mode or vice versa, please proceed as follows:
- Shut down PC or device (= switch off by software).
- If previously connected to TrutzBox, now connect to the Internet router or vice versa.
- Switch on/restart the device (now the device automatically receives an IP address valid in this network area).

1.5 Phases, users and administrator
This manual describes two roles in these words:
”User”
Anyone using TrutzBox functions is referred to in this manual as "'User'".
Administrator
A person who uses certain administrative functions of the TrutzBox that are not available to every user is described in this manual "Administrator".
With private use of the TrutzBox the administrator is usually an adult, in families e.g. a legal guardian.
For commercial use of the TrutzBox, the administrator is usually an internal or external IT administrator.
In general, the following phases can be distinguished when using the TrutzBox:
| Phase | activities | |
| start up (ca. 15 Min.) |
Unpacking, checking, connecting and switching on the TrutzBox | Administrator |
| set up (ca. 30 Min. plus updates) |

3 TrutzBox® Setup (for TrutzBox® Administrator)
This chapter includes
- Start-up of the TrutzBox®
- Set-up of the TrutzBox®
The aim is to connect as many or all devices as possible in the home network via the TrutzBox®.
However, this only happens after setting up according to the manual.
After the TrutzBox® is connected to the Internet router, start "small" by entering the TrutzBox® as "Proxy" (= deputy, quasi "doorman") in a browser of a connected PC and thus controlling the TrutzBox® the incoming and outgoing Internet traffic of this connected PC.
After completing this quick start, the user can
- surf without tracks (at least with few tracks) with presets,
- encrypted email via web access and
- use the proposed filter lists for child and youth protection.
Once this state has been reached, further devices should be connected to the TrutzBox® in a controlled manner.
Devices for which a proxy can be set up
Devices for which a proxy can be configured (e.g. browser on PC or, if available, on TV set) should first be connected to the Internet router via WLAN (or network cable) and the TrutzBox® should be entered as the proxy.
Once you have gained experience in this way, you can connect the devices directly to the TrutzBox® via WLAN (or network cable).
Devices for which no proxy can be set up
Devices for which no proxy can be set up (e.g. refrigerator or toothbrush) should be connected to the TrutzBox®; then the communication characteristics can be monitored and, if necessary and controlled, external communication can be permitted.

3.2 TrutzBox® Set up
To set up your Trutzbox, you can do this with any browser. The process is a little different, depending on which browser is used. There are two groups:
- Mozila Firefox (with own certificate management) and
- Internet Explorer or Google Chrome (with shared certificate management in the operating system).
The following example shows the processes for both types; starting with Mozilla Firefox.
After connecting the TrutzBox® according to chapter "Connecting the TrutzBox®" it starts up. This can take 9-10 minutes.
Then connect your computer's browser to the TrutzBox® by entering"http://trutzbox" in the browser's address bar..
It is recommended to open 2 browser windows, so that you can work e.g. in the left window on the TrutzBox® user interface and directly next to it, e.g. in the right window, you can access the manual or the browser administration.
This is shown below:
- Part I is the same for all browser types,
- Part II distinguishes between Firefox (2a) and "Non-Firefox" (2b) and
- Part III is identical again.

The TrutzBox® checks if there are current updates; if yes, they will be downloaded now (1).
Please note that this process can take up to 30 minutes.
-> Table of Contents (of this manual)
The updates are completely downloaded when the window " Abschluss der Einrichtung " appears.
Click directly - without clicking on steps 1 & 2 - on the "Fertig" button to end the setup process.
(Step 1 follows only after the installation; Step 2 can now be saved due to the further development of the TrutzBox).

Then the TrutzBox user interface appears automatically and shows you:
Now the quick start is complete.
-> Table of Contents (of this manual)
After downloading, your TrutzBox® is ready for operation.
The next step is to
- set up the TrutzBox as a proxy; see Chapter entitled "Connecting the device to the TrutzBox" and
- import the root certificate (if you want to use other devices with a browser in addition to your PC); see the "Certificates" chapter.
On every other device with a browser that uses the TrutzBox®, the certificate
- if browser is Firefox: must be imported into the Firefox certificate management,
- if browser is not Firefox: must be imported into the certificate management of the other browser, and thus automatically into the certificate management of the operating system. (see chapter "Certificates").
To use TrutzMail or TrutzChat, the TrutzBox certificate must also have been imported into the certificate management of the operating system.
The TrutzBox certificate only needs to be imported once into the certificate management of the operating system and is then available there for
- all non-Firefox browsers and
- TrutzMail and
- TrutzChat.
If you do not import the certificate into the browsers and notify the mail system, you will be prompted for security confirmation each time you open it.
Therefore it is recommended to download the TrutzBox® certificate from the TrutzBox® to the device with browser and import it into the browser afterwards.

3.2.5 Disable IPv6
The TrutzBox works exclusively with IPv4 addresses.
If your TrutzBox is not connected to the router or your terminal device (e.g. PC) cannot reach the TrutzBox, one reason for this may be that the router assigns IPv6 addresses. To avoid this, it should be ensured that the router assigns IPv4 addresses.
To disable IPv6 addresses, proceed as follows:
In the FRITZ!box user interface, call up Internet.

4 Use of the TrutzBox® (-> for users)
The TrutzBox® is delivered by Comidio with security settings suitable for everyday use, so that even inexperienced users can email and surf immediately protected and without a trace.
The following sections describe the functions and options that the inexperienced user can use immediately after setting up TrutzBox.
These include:
- TrutzBrowse: Traceless surfing through modified, incomprehensible browser profile data.
- TrutzMail: End-to-end email service with encrypted content and encrypted metadata.
- TrutzContent: Maximum protection for children and young people by using filter lists to block inappropriate websites.
- TrutzRTC': Real-time communication with TrutzChat (Messaging) and TrutzMeeting (Audio and Video Conferencing Service)
- TrutzBase: Use of modern virus protection, firewall and intrusion detection systems
4.1 Traceless Surfing - TrutzBrowse
Independent of browser (e.g. Mozilla Firefox, Chrome, Internet Explorer, Safari, etc.) and operating system (Microsoft windows, Apple iOS, Linux), the TrutzBox helps to avoid data tracing while surfing.
Use your browser as usual (in the following as an example with windows 7 and Firefox).
4.1.1 TrutzBrowse in standard operation
The TrutzBurg symbol in the upper right corner of the website indicates that TrutzBrowse is activated with the security settings. With the above setting, the TrutzBox (symbol: TrutzBurg) and the Tor network (symbol: onion) are activated.
The color of the TrutzBurg shield indicates the setting of the security slider for this URL; green = level 1 = highest security level; red = level 9 = lowest security level.
If there are operating elements on the website which are hidden by the TrutzBurg and can therefore no longer be operated, the TrutzBurg can be moved to another corner of the browser window.
For touch screens, simply touch the symbol for longer than 1s.
After clicking on the TrutzBurg, the security slider and four further functions are available.
The Security-Slider can be set to 10 security levels (Level 1 = highest protection up to Level 9 = lowest protection; Level 10 = for this website the TrutzBox is switched off). From level 1-9, the user can make the settings himself. If set to level 10 (TrutzBox protection is disabled), only the administrator can reset the level for this website.
On delivery, the security slider is set to "highest security level" (level 1, green, far left).
If the website shows malfunctions, e.g. because it wants to store a cookie, the user can gradually deactivate individual security and anonymisation measures by dragging the security slider to the right (towards red) in order to restore the website's functionality.
However, the security level should only be reduced for trusted websites.
Click on "Details" to see a list of all web accesses accessed from this website.
Blocked HTTP calls are marked by a "red crossed out circle“.
The overview also shows the HTTP headers that have not been completely blocked (marked by a "green tick in a green circle").
This makes it obvious which data was transmitted from the browser to a Web server ("Request" tab) and which data went from a Web server to the browser ("Response" tab).
Depending on how the TrutzBox® is configured for the current position of the Security Slider, certain HTTP header data may not be transmitted to the web server at all (blocked headers) or may be changed (replaced headers).
On the left, the HTTP calls are listed, which are automatically called in the background - without the user's active intervention - in addition to the web page called up by the user (here: www.krone.at). On the right under "Details" you can see which header information has been blocked or replaced.
Click on one of the HTTP calls listed on the left to obtain additional information on this.
Set a check mark to " Nur Blockierungen anzeigen ", then only the blockings are listed.
-> Table of Contents (of this manual)
4.1.2 TrutzBrowse for experts
The TrutzBox® monitors web access and is thus able to prevent unwanted data traffic. The TrutzBox® distinguishes whether a device or a user calls up a web page directly or whether a web server - after the deliberately called up web page has been loaded - contacts further web pages and loads them without the user's knowledge and without his consent.
The TrutzBox® offers two different basic functions for this purpose:
1. TrutzContent:
A content filter that prevents a device or user from directly accessing a particular Web page. Examples of unwanted calls:
- A young person wants to load a website with content harmful to young people.
- An Internet device unnoticedly calls up a web page in the background without a user deliberately initiating it. These can be TVs, washing machines or game consoles (if they are connected to the Internet), or even the standard Internet browser of the user's PC, which in turn contacts Mozilla or Google or the server of a plug-in provider independently, for example.
The TrutzBox® checks if the contact to such a server is allowed and blocks the connection to this server if necessary.
2. TrutzBrowse:
A user or an Internet-enabled device has validly accessed a Web page. When loading the page, however, this website contacts other web servers (often commercial data trackers) that may be interested in the user data. TrutzBox® monitors calls to other web servers that are indirectly contacted without the user's knowledge during the loading process of the deliberately accessed web page.
In both case 1 (TrutzContent) and case 2 (TrutzBrowse), the TrutzBox® compares every web page called up with the web pages (filter lists) known to it. Comidio provides approx. 110 filter lists covering 55 different Internet topics. These filter lists are updated regularly. The TrutzBox® Administrator can add own filter lists if required.
Approach of the TrutzBox®:
Wenn ein Internet-Nutzer eine Webseite aufruft, dann prüft die TrutzContent Funktion zunächst, ob der PC und/oder der Nutzer, der diesen Webseitenaufruf angestoßen hat, diese Seite überhaupt aufrufen darf. Soll diese Webseite gemäß den Filterlisten blockiert werden, dann bekommt der Internet-Nutzer im Browser eine Fehlermeldung angezeigt.
If the website can be accessed, the TrutzBox® allows the data from the web server to pass to the browser, but it monitors each call to other web servers that the website then contacts automatically. Usually a website loads additional content from many other web servers. For each contact with a web server other than the originally called web server, the TrutzBox® checks whether this later called web server is in a filter list group "TrutzBrowse". If it is listed there, the connection to this server will be blocked.
This prevents data tracker calls that are programmed into most websites, and data trackers cannot spy on user behavior.
Each time a Web server is granted (permitted) access, information is sent from the Web browser to the Web server via the HTTP header (http request header). Without the TrutzBox® the browser would then deliver this requested data to the web server. This can be very personal data, such as which other pages you have recently called up, are you currently logged on to Facebook or how exactly does your PC/browser configuration look in order to recognize you on further calls. The HTTP header filter also controls the setting and retrieval of cookies
With its TrutzBrowse function, the TrutzBox® is thus able to control the entire HTTP data exchange on the Internet and to block or falsify these HTTP header data as long as they are not absolutely necessary..

4.1.2.1 Handling SSL connections
The proxy can only break (and analyze) an SSL-encrypted connection between a program and a server if the SSL key has been signed by one of the known certificate authorities. Here are two cases where breaking the encrypted connection does not work:
- if an app establishes an encrypted connection to the server, but the key used is a self-generated key and has therefore not been signed by an official certification authority. If the app is a browser, the user is asked if he accepts the server. If the app is not a browser, the user cannot be requested.
- if the client is authenticated. In this case, a key is usually programmed into the client.
In all cases where the SSL connection cannot be broken, the SecSlider is automatically set to L10 and thus the data transfer is no longer analyzed. This ensures that apps still work "without manual intervention". The user (or the TrutzBox administrator) can deactivate this automatic feature in the "Configure filter" menu with the option "If SSL errors occur, automatically deactivate filtering for the selected domain". The data connection is nevertheless displayed in "Status" for checking purposes. Since this automatic activation only becomes effective if the server has not yet been set in the slider table, this automatism can also prevent a single server if the SecSlider is set manually to any value for this server.

4.1.3 Install proxy switch for activating/deactivating the TrutzBox® in the browser
Attention: Switching the TrutzBox on and off as a proxy (="Call forwarding") only makes sense if the browser to be used (or the terminal device used, e.g. PC) is operated in "proxy mode", i.e. the PC is connected to the Internet router (and not directly to the TrutzBox).
If the browser to be used (or the end-device used, e.g. PC) is operated in "transparent mode", i.e. the PC is connected directly to the TrutzBox (and not directly to the Internet router), I do not need a switch, as the PC is constantly protected via the TrutzBox and switching a proxy on or off makes no difference..
As is known, it is possible to activate or deactivate the TrutzBox® functionality "TrutzBrowse" by activating/deactivating the "PAC" file in the browser settings.
If you want to save yourself these "efforts", you can also install a "proxy switch" (in the form of a downloadable "Add-On" = additional function) in the respective browser and then easily activate or deactivate the TrutzBrowse functionality by simply pressing or selecting it in the browser header line.
The following shows the installations of two proxy switches:
- for Browser "Firefox": Add-On „Proxy Switcher“ and
- für Browser "Chrome": Add-On „Proxy SwitchyOmega“.
Of course, other proxy switches can also be implemented and used.
4.1.3.1 Proxy Switch for "Firefox" Browser
Attention: Switching the TrutzBox on and off as a proxy (=" Redirection") only makes sense if the browser to be used (or the end-device used, e.g. PC) is operated in "Proxy Mode", i.e. the PC is connected to the Internet router (and not directly to the TrutzBox).
If the„FoxyProxy Standard“ add-on is implemented, the user can activate and deactivate the "Trutzbox" proxy and thus the TrutzBrowse function by clicking the Proxy Switcher button (orange fox head) in the browser header.:
- to switch on: by clicking on the symbol "crossed out, orange fox head" the FoxyProxy selection window appears; there click on the green line "Use proxy Trutzbox for all URLs (ignore patterns)'" and the proxy is switched on and the symbol "orange fox head" appears.
- to turn off: by clicking on the symbol "orange fox head" the FoxyProxy selection window appears; click on the red line "Turn Off All Proxies" and the proxy is switched off and the symbol "crossed out, orange fox head" appears.

4.3 Protection of minors - TrutzContent
The TrutzBox® monitors web access and is thus able to prevent unwanted data traffic. The TrutzBox® distinguishes whether a device or a user calls up a web page directly or whether a web server - after the deliberately called up web page has been loaded - contacts further web pages and loads them without the user's knowledge and without his consent.
The TrutzBox® offers two different basic functions here:
1. TrutzContent:
A content filter that prevents a device or user from directly accessing a particular Web page. Examples of unwanted calls:
- A young person wants to load a website with content harmful to young people.
- An Internet device that unnoticedly calls up a web page in the background, without a user deliberately initiating it, calls up a web page in the background. These can be TVs, washing machines or game consoles (if they are connected to the Internet), or even the standard Internet browser of the user's PC, which in turn contacts Mozilla or Google or the server of a plug-in provider independently.
The TrutzBox® checks if the contact to such a server is allowed and blocks the forwarding if necessary.
-> Table of Contents (of this manual)
4.4 Real time communication- TrutzRTC
As part of the updates, two real-time communication functions are implemented on the TrutzBox® (without the customer's active involvement and free of charge):
- TrutzChat = XMPP Service for messaging and, depending on the client used, other functions such as audio, video communication, file transfer, screen sharing ...
- TrutzMeeting Audio and video conferencing service: Server on which you can connect to a browser that supports the WebRTC standard and which is capable of connecting several audio or video conference participants.
TrutzRTC runs automatically, does not need to be configured and has no user interface on the TrutzBox.
-> Table of Contents (of this manual)
4.4.1 TrutzChat (XMPP Service)
It works similar to e-mail. The XMPP server on the TrutzBox manages users, their online status and their messages. If a message is to be sent to a subscriber who is not on the same server (i.e. on a different TrutzBox) as the sender, the target server is determined, contact is made with it and the message is delivered to this XMPP server. The same applies not only to messages but also to other functions, such as Presence status
Comidio has extended the XMPP server on the TrutzBox so that it is able to use the same security functions as those used by TrutzMail. This means:
- Communication partners are addressed with the TrutzMail address.
- The connection establishment and the message transmission with users on another TrutzBox, take place via Tor hidden services.
- The same certificates and keys are used to encrypt messages and authenticate the TrutzBox of the communication partner as for TrutzMail.
Once created, TrutzMail addresses can also be used directly for messaging.
Structure of the XMPP service between the TrutzBoxes
-> Table of Contents (of this manual)
4.4.1.1 preconditions:
In order to use the TrutzChat service, a TrutzMail address' and an XMPP-enabled program on the mobile device (PC or mobile) are required. Chat programs that support the XMPP protocol are available for all common operating systems with different features.
These links give a good overview of available XMPP clients:
- https://de.wikipedia.org/wiki/Liste_von_XMPP-Clients
- https://de.wikibooks.org/wiki/XMPP-Kompendium:_Einrichtung
- http://xmpp.org/software/clients.html
The individual selection depends partly on requirements, partly on taste.
Comidio uses the following clients:
| Apple Macintosh | Adium (https://adium.im) |
| Microsoft Windows | PSI (http://psi-im.org) |
| iOS | ChatSecure (https://chatsecure.org) |
| Android | Xabber (https://www.xabber.com/) |
After installing such a messaging client, the XMPP server must be configured in the client. All you have to do is enter the corresponding TrutzMail address with password.
Since many XMPP clients determine the server name from the e-mail address, the incorrectly determined name "comidio.email" must still be changed to "trutzbox”.
The XMPP default port 5222 remains unchanged.
Several TrutzMail addresses can also be configured in one client.

4.4.1.2 TrutzChat XMPP Standard Functions
Depending on the functionality of the messaging client, the XMPP server on the TrutzBox supports the following XMPP standard functions:
- Instant-Messaging: Text messages incl. formatting and emoticons
- Create and manage communication groups, group chats (multi-user chat - MUC ), but currently only for communication participants who are logged on to the same TrutzBox.
- Audio/Video Communication: Telephone Calls
- File transfer: Send files to the communication partner(s)
- Screen Sharing: makes one's own screen visible to others
- Remote-Desktop: the communication partner can operate my PC
- OTR (Off-the-Record Messaging): unofficial, confidential, non-public communications
- Online-Status, Last-Seen: is the communication partner online, ready to talk... or when was the last time he was online
-> Table of Contents (of this manual)
4.4.1.3 External connections to TrutzRTC
As long as the TrutzBox with the host name "trutzbox" is available, the messaging client can connect directly to the XMPP server on the TrutzBox.
However, this only works from the home network if the client is connected to the Internet router or the secure network of the TrutzBox (transparent mode).
To connect to the XMPP server on the TrutzBox while travelling, the TrutzBox " Fernzugriff " should be used.
To do this, set up the TrutzBox remote access as described in „Fernzugriff“ and authorise the TrutzRTC user for remote access under " Benutzer verwalten " on the TrutzBox.
If „Fernzugriff“is then set up and started on the mobile device, the messaging program can access the TrutzRTC server as in the home network.
There is no need to open additional ports on the Internet router at home.

4.4.2 TrutzMeeting: Audio- and Video-Conference Service
Using the XMPP server and the correct messaging client, it is possible to establish an audio/video connection, but only with one other participant, and it is necessary that all participants use a client that supports the same audio/video code. Therefore, standard XMPP clients are not an optimal solution for telephone or video conferences.
To provide TrutzBox users with a secure solution for multiparty telephone or video conferencing, the TrutzBox offers a WebRTC-enabled conference server that allows audio/video conferencing directly from a standard Internet browser, without the need for additional software.
Around the TrutzBox user also a secure solution for telephone or video WebRTC is a living standard defined in phases, which is gradually implemented by the browser manufacturers. This means that there are no uniform functionalities across all browsers and the WebRTC functions run differently stable.
For example, the screensharing function is not yet implemented stably.We will update with appropriate browsers.
4.4.2.1 preconditions
During the later operating phase, the maximum number of video conference participants will correspond to the TrutzMail addresses booked.
There is no participant limit in the current beta test phase.
To start a video conference, simply access the TrutzBox on port 9082 using a WebRTC-enabled browser.
A room name is appended to the end of the link:
z.B.: https://trutzbox:9082/raumname
No special characters may be used for the selected room name!
4.4.2.2 procedure
Durch Aufruf der oben genannten URL verbindet sich der Browser mit dem Raum “raumname”. Dabei sind zwei Fälle zu unterscheiden:
- The room does not yet exist:
so you are now the first person who wants to create this room, and you are the "room administrator" for this room. Then it is necessary to log on to the conference server with his TrutzMail address and the TrutzMail Password. This means that only TrutzBox users who have a TrutzMail account on this TrutzBox can open a new room. After creating and connecting to the room, the room administrator can optionally define another password for this room.
- The room already exists:
then the browser connects to the room. If the room administrator has placed a password in the room, this must now be entered. If the room has already been created, anyone can connect to the room. He does not need to be registered as a TrutzBox user or have a TrutzMail address. As soon as the browser is connected to the room, you should enter your "Anzeigenamen" by clicking on the connection window below.
Positioning the mouse at the top of the screen opens an operating menu.
This menu offers the following functions:

4.4.2.3 Screen-Sharing
With the function "Share your own screen with the participants" it is possible to share your own screen content with other conference participants.
Since all browsers have a built-in security setting that prevents software from reading the screen content, the browser must be informed that the TrutzBox may read the screen content.
Chrome
With Chrome it is necessary that this feature is already activated when you call it up.
Chrome on Mac
For this purpose on the
- Mac: start chrome in the console with this command:
open -a 'Google Chrome' --args '--enable-usermedia-screen-capturing'

4.4.2.4 Performance limits of the conference server
The TrutzRTC conference server is based on the open source software Jitsi-Video-Bridge . Although this conference server is very powerful and the TrutzBox hardware is also very powerful, the number of participants is not unlimited. The number of participants depends on the speed of the Internet connection of each individual participant and the TrutzBox owner. Approx. 40KBit/s up- and down-load speed per subscriber is sufficient for voice transmission. For camera or screen sharing up to 800 KBit/s are required. Thus, with normal DSL/VDSL Internet connections, bottlenecks will probably occur before the TrutzBox hardware becomes a bottleneck. Such Internet bottlenecks can best be analyzed on the Internet router.
4.4.2.5 External connections to the TrutzRTC conference server
No TrutzBox is required to connect to the TrutzBox conference server externally, i.e. via the Internet. Who knows the link (and the possibly assigned password), can participate in the conference. This makes it easier to use webinars or spontaneous conferences.
To do this, however, these two ports must be opened on the Internet router and forwarded to the TrutzBox:
- TCP-9082
- UDP-9083
With the link "https://externe-ip-adresse:9082/raumname" the room can then be joined on the Internet.
Since the external IP address changes once a day for most home Internet connections, it is advisable to use a DynDNS service here as well.
Another way to determine the correct external link for participating in a conference has been integrated into the TrutzBox XMPP server. If you transmit the symbol "#" with a room name to a person in the XMPP chat, then this "command" is converted into the external link to the conference server. This means that:
#meinraum
converts into the address
https://188.107.13.86:9082/meinraum
which the chat participant can click directly.

4.5 TrutzBox® shutdown (do not unplug!)
If a TrutzBox is to be switched off and/or restarted, please DO NOT disconnect the plug, but proceed as follows:
4.5.1 TrutzBox® shutdown, "switch off" via TrutzBox user interface
In the TrutzBox user interface:
- Click on „System“ -> „Ein-/Ausschalten“
- if you want TrutzBox to start up again: Click on the button „Neu starten“
- if TrutzBox is to be switched off: Click on the button „Ausschalten“
4.5.2 TrutzBox® shutdown, "switch off" via Webmin
If the administrator can no longer access the TrutzBox user interface, an attempt is made to access it directly via Webmin. Call up in the browser: https://trutzbox:10000/ :
- Enter admin as user
- Enter the administrator password of the TrutzBox
- Click on „System“ -> „System-Start und -Stop“ and scroll all the way down
- if you want TrutzBox to start up again: Click on the button „System neu starten“
- if TrutzBox is to be switched off: Click on the button „System herunterfahren“
4.5.3 TrutzBox® shutdown, "switch off" Emergency
If the administrator
- neither via the user interface
- nor about Webmin
an access, in an emergency, the "connector must be disconnected".
Please wait approx. 10 seconds and then reconnect the power supply.
If the TrutzBox does not start up (correctly) in approx. 15 minutes, please contact Comidio Support : Email to support@comidio.de .

4.6 TrutzServices
4.6.1 TrutzServices in active subscription
The quality of protection provided by TrutzBox® depends largely on how up-to-date the software is with regard to functions and data. This is only guaranteed if the TrutzBox® receives regular and automatic updates.
TrutzServices, the Comidio services for TrutzBox®, include the following update services:
- TrutzBrowse: Updates for header extensions, slider presets and blacklists,
- TrutzMail: Updates of Receiver Certificates,
- TrutzContent: Updates for filter lists,
- TrutzBase: Signatures and updates for virus scanners and
- TrutzBox® Software: Fault-fixes, security updates and minor functional extensions.
All these services are included in TrutzServices.
The updates were carried out partly regularly (e.g. virus scanner updates), partly on an occasion basis (e.g. security updates). Major updates run in the early morning hours (around 04:00) so that they do not disturb the user.
Therefore it is not only useful to leave the TrutzBox® constantly switched on for the e-mail exchange, but also necessary for the execution of the updates.
4.6.2 What happens if TrutzBox services are not being extended?
In this case, the TrutzMail certificates expire, i.e. services that are bound to these TrutzMail addresses can no longer be used. Currently these are:
- the exchange of TrutzMails,
- TrutzRTC (Video Conferences and Chat),
- Comidio-Software-Updates.
The Debian updates can still be imported. All other services, such as TrutzBrowse and TrutzContent can still be used, but without updating the filter lists. The same would apply if Comidio did not renew its services.
Since the TrutzBox hardware is based on a high-quality standard board (an APU2 from PCEngines), the hardware could be used as a powerful server (including the built-in SSD disk) for other purposes.
