Install GLPI (IT and Asset Management) Tool with Fusion Inventory in Debian Linux

http://www.tecmint.com/glpi-it-asset-management-with-fusion-inventory-in-debian-linux/


Any type of business is bound to have innumerable amounts of items that need to be inventoried, tracked, and managed. Doing so by means of pen and paper not only takes excessive amounts of time but is often prone to multiple user errors. Moving to a digital system such as Excel/Libre Calc worksheets is a little bit more productive and easier to back up but does present some other interesting issues such as access to the spreadsheet, inability to easily query data, or the simple fact that multiple spreadsheets easily becomes a logistical nightmare!
GLPI is a fantastic piece of information-resource management software that can be installed to track company resources. GLPI is comparable in functionality to several commercial pieces of software such as LanSweeper,EasyVista,and ManageEngine. GLPI boasts several very useful features:
  1. Hardware/Software inventory
  2. Network and printing hardware inventory
  3. Support for Fusion Inventory and OCS Inventory
  4. Computer peripherals inventory such as monitors, scanners, telephones, etc
  5. Help-desk Ticketing System
    1. SLA Management
    2. Change Management
    3. Project Management
  6. Reporting to PDF, CSV, PNG, SVG, etc
When GLPI is paired with Fusion Inventory:
  1. Software deployment abilities
  2. Automated inventory through client agents
  3. Ability to do handle Android, Windows, Linux, BSD, HP-UX, and many other operating systems
All in all with GLPI and Fusion Inventory installed, the combination can be used to create an all encompassing help-desk/document management/inventory system for businesses of all sizes.
This tutorial will walk through the steps necessary to quickly setup, configure, and begin importing inventory into GLPI with the help of Fusion Inventory on Debian 8 Jessie, but the same instructions also works on Debian based systems like Ubuntu and Mint.

Necessary Components

  1. Debian 8 Jessie already installed ( TecMint has an article on installing Debian 8 here:
    1. Debian 8 Installation Guide
  2. Working network connection (necessary for the automatic inventory).
  3. A secondary machine to install the inventory agent (also with a network connection to the Debian server)
  4. Root/Administrator access to both machines

Installation of GLPI/Fusion Inventory Server

Step 1: Dependency Installation

1. The first step in the process is to boot up and prepare the Debian server. GLPI will require Apache2MySQL, and some PHP additions in order to function properly. The easiest way to get these packages is with the Aptmeta-packager.
# apt-get install apache2 mysql-server-5.5 php5 php5-mysql php5-gd
This command will download and install the necessary packages and start the basic server services. WhileMySQL is installing, it will likely ask to have the MySQL root password set. Set this password but DO NOT forget it as it will be needed soon.
Set MySQL Root Password
Set MySQL Root Password
2. After all of the packages finish installing, it is always a good idea to make sure that the server services are running. This is easily accomplished by evaluating the system to see what services are listening on what ports with the ‘lsof‘ utility.
# lsof -i :80     [will confirm apache2 is listening to port 80]
# lsof -i :3306    [will confirm MySQL is listening to port 3306]
Another way to confirm apache2 is working and delivering a web-page is to open a web browser and type the Debian server’s IP address in the URL bar. If Apache2 is working, the web browser should return the “default” Apache2 page.
http://Your-IP-Addresss
Apache Default Page
Apache Default Page
Now that Apache2 is at least serving up a web-page, lets first prepare the MySQL database and then configureApache2 to server GLPI.

Step 2: MySQL Configuration

3. From the Debian server, log into the MySQL command line interface using the ‘mysql‘ command.
# mysql -u root -p
This command will attempt to log into MySQL as the MySQL root user (NOT the system root user). The ‘-p‘ argument will prompt the user for the MySQL root user password that was configured when MySQL was installed in the prior paragraph. At this point, a new database ‘glpi‘ needs to be created for GLPI. The SQL command to do accomplish this task:
mysql> create database glpi; 
To confirm that this new database was indeed created, the ‘show databases;‘ command can be issued. The result should look similar to the below screen-shot.
mysql> show databases;
Show MySQL Databases
Show MySQL Databases
4. From here, a new user with privileges to this database should be created. It is never a good idea to use the root user! To create a new MySQL user and assign them permissions to the ‘glpi‘ database:
  1. create user ‘glpi’@’localhost'; → creates a MySQL user called ‘glpi‘.
  2. grant all privileges on glpi.* to ‘glpi’@’localhost’ identified by ‘some_password'; → this grants all database privileges on the database called ‘glpi‘ to the newly created user ‘glpi‘ and then assigns a password required for that user to access the SQL database.
  3. flush privileges; → run this for the new privileges to be read by the MySQL server.
mysql> create user 'glpi'@'localhost';
mysql> grant all privileges on glpi.* to 'glpi'@'localhost' identified by 'some_password';
mysql> flush privileges;
At this point, MySQL is ready and it is time to obtain the GLPI software.

Step 3: Obtain and Prepare GLPI for Installation

5. Obtaining GLPI is very simple and can be accomplished one of two ways. The first method is to visit the project’s home page and Download GLPI Software or via the command line utility known as ‘wget‘.
This will download and install version 0.85.4 which is the current version as of this article.
# wget -c https://forge.indepnet.net/attachments/download/2020/glpi-0.85.4.tar.gz 
6. Once the software is downloaded, the contents of the tarball need to be extracted. Using the tar utility, the contents can be decompressed, extracted, and placed in the proper location on the Debian server for the GLPI webpage to be accessible.
This will extract the tarball contents to a folder called ‘glpi‘ in the /var/www directory. By default, this is the directory that Apache2 serves files on Debian.
# tar xzf glpi-0.85.4.tar.gz -C /var/www 
7. The above tar command will extract all the contents into the ‘/var/www/glpi‘ directory but it will all be owned by the root user. This will need to be changed for Apache2 and other security reasons using the chowncommand.
This will change the owner and primary group ownership for all of the files in /var/www/glpi to www-datawhich is the user and group that Apache2 will be using.
# chown -R www-data:www-data /var/www/glpi
At this point, Apache2 will need to be reconfigured in order to serve the newly extracted GLPI contents and the following section will detail the steps.

Step 4: Configuring Apache2 to serve GLPI

8. Apache2 in Debian systems is setup a little differently than other distributions. Some find it easier to manage and others find it more difficult.
This tutorial will keep things as simple as possible and will assume that GLPI is the only website being served by this Apache2 server and that it will be served on the traditional port 80 HTTP port.
This will allow for the least amount of modifications to the default Apache2 install and will allow users to get GLPI up and running quickly. Let’s begin!
The first thing to do is switch directories to the Apache2 configuration files directory. The configuration directory is ‘/etc/apache2/sites-available‘ and the command:
# cd /etc/apache2/sites-available
9. The only items in this directory by default will be the two default Apache2 site configuration files. A new configuration file should be created for GLPI and can be created from the default in this directory using the copycommand.
This will copy the configuration of the default site into a new configuration file for GLPI.
# cp 000-default.conf glpi.conf 
This new GLPI configuration file needs to be modified so that apache2 knows where the files to serve for GLPI reside. Open ‘glpi.conf‘ with a text editor and proceed to configure as follows:
  1. nano glpi.conf → open glpi.conf in the nano text editor.
  2. DocumentRoot /var/www/glpi → This tells Apache2 where the files for GLPI start. This line isn’t a command but rather something that is added to the glpi.conf file.
# nano glpi.conf

DocumentRoot /var/www/glpi
Configure Apache for GLPI
Configure Apache for GLPI
10. Apache2 has a TON of other options but for brevity’s sake, this change is the only change needed in this file. Now apache2 has to be made aware of the new GLPI site as well as told to stop serving the “default” page. This is easily accomplished with two tools a2ensite and a2dissite.
  1. a2dissite 000-default.conf → This will disable the default website Apache2 serves.
  2. a2ensite glpi.conf → This will enable the newly created GLPI website configuration.
  3. service apache2 reload → This will be necessary for Apache2 to stop/start serving the above changes.
# a2dissite 000-default.conf
# a2ensite glpi.conf
# service apache2 reload
At this point, Apache2 should be configured and serving the GLPI site information, the MySQL database is created and has an assigned user. The next step is to run the GLPI installer.

Step 5: Installing and Configuring GLPI

11. To start the installation of GLPI, simply visit the IP address of the server running Apache2. This can be done from the server itself if a graphical desktop environment has been installed; otherwise the other machine requested for this tutorial will be needed.
Upon visiting the IP address of the Apache2 server, the user will be presented with the GLPI installation page:
http://Your-IP-Address
Select GLPI installation Language
Select GLPI installation Language
12. At this point, select the appropriate language and click ‘OK‘. The next prompt will ask if this install is an upgrade or a fresh installation. This tutorial is assuming that this will be a fresh installation of GLPI.
GLPI Installation
GLPI Installation
13. The next screen will be a quick dependency check by GLPI. Everything on this next page should come back with a green light. Anything with a red light should be addressed and corrected on the server.
GLPI Dependency Checks
GLPI Dependency Checks
14. When all the lights are green, the next step is to inform the GLPI installer where the MySQL database is as well as the credentials to access the database. This information was determined earlier in this guide and should be as follows:
GLPI MySQL Database Settings
GLPI MySQL Database Settings
The server name of ‘localhost‘ can be used in this example due to the fact that this installer is running from the same server as the MySQL server.
Click continue after the three fields are filled in and the GLPI installer will run a SQL check to ensure that it can make contact with the SQL database. Since a database was already created earlier be sure to select that database in this step.
Select GLPI MySQL Database
Select GLPI MySQL Database
15. This next step will take a couple of minutes depending on the speed of the MySQL server. The final page that the GLPI installer will show will be the default username/password page.
The only user account that will be needed for this guide will be the administrator account which defaults to username: ‘glpi‘ and password: ‘glpi‘.
GLPI User Login Details
GLPI User Login Details
16. At this point, GLPI is ready for usage. Click the ‘Use GLPI‘ button to be taken to the login screen and log in as the administrator. Once logged in to GLPI, the GLPI landing screen will issue some warnings about the user-names above having the default passwords configured.
For now this can be ignored but should be changed when moving GLPI to production! The other warning will be a warning that recommends removing the installer file. This is easily accomplished by running the following ‘rm‘ command on the Debian server:
# rm /var/www/glpi/install/install.php
This concludes the installation of GLPI. At this point users can start adding inventory, creating tickets, creating a document library, and many other tasks. However, the rest of this guide will talk about how to setup the Fusion Inventory plug-in to further extend the capabilities of GLPI.

Step 6: Installation and Configuration of Fusion Inventory

17. Now that GLPI is up and running, it is time to add the Fusion Inventory plug-in. Heading back over to the Debian server, the Fusion Inventory plugin can be obtained with another simple wget command.
# cd /var/www/glpi/plugins
# wget -c http://forge.fusioninventory.org/attachments/download/1755/fusioninventory-for-glpi_0.85+1.1.tar.gz 
18. Now that Fusion Inventory has been downloaded, the contents of the tarball need to be extracted and then ownership changed in order for Apache2 to have access to the new plug-in on GLPI’s behalf:
# tar xzf fusioninventory-for-glpi_0.85+1.1.tar.gz
# chown -R www-data:www-data fusioninventory 
This above chown command will change the ownership of all the files in the newly extracted folder. The ‘tar‘ command above must be run BEFORE this command!
19. Now all of the files are ready for GLPI to install the Fusion Inventory module. Head back over to the second computer (the one with the web browser) and log-in to GLPI.
At the top of the screen, there are several menu options for GLPI. One of these options will say ‘Setup‘. Hover over this menu and wait for the drop down menu to appear and at the bottom will be a ‘plug-ins‘ option.
Install Fusion Inventory Plugin
Install Fusion Inventory Plugin
20. The next screen will be the installed and ready to be installed list of plug-ins for GLPI. Assuming that Fusion Inventory was placed in the proper directory in the above paragraphs (/var/www/glpi/plugins) this page will show the Fusion Inventory plug-in waiting to be installed.
Fusion Plugin Install
Fusion Plugin Install
21. Click the ‘Install‘ button to install Fusion Inventory into GLPI. The page should refresh and then Fusion Inventory will need to be ‘enabled‘ which is done by clicking the newly visible ‘enable‘ button.
Notice that the ‘Status‘ field for Fusion will say ‘Installed / not activated‘ until the ‘Enable‘ button is selected!
Enable Fusion Inventory Plugin
Enable Fusion Inventory Plugin
22. Once the ‘Enable‘ button is selected, the Fusion Inventory plug-in will now be activated and ready for configuration.
In GLPI, a new ‘Plugins‘ menu will be visible and hovering over the menu will present a drop-down menu labeled ‘FusionInventory‘. Clicking on this option will likely present the following error screen since Fusion does not have a URL for agents to access the system configured yet.
Fusion Inventory Plugin Error
Fusion Inventory Plugin Error
23. To fix this issue, hover over the ‘Administration‘ menu option. When the drop down menu appears, select the ‘Entities‘ dialog. When the page loads, select ‘Root Entity‘ and then on the left side of the webpage, select the ‘FusionInventory‘ selection.
This will allow for the service URL to be set. The service URL in this tutorial can simply be the server’s IP address however, if a functional DNS system (such as BIND9) is setup, an actual URL can be used here as long as the appropriate changes are made in the DNS system as well.
Set Fusion Service URL
Set Fusion Service URL
Finally, GLPI and Fusion are ready to go. The next task is to start importing inventory into the system. This tutorial will continue with installing the Fusion Inventory Agent and confirming that the agent properly sends the inventory information to the server.

Step 7: Fusion Inventory Agent Installation

24. Now that all of the difficult stuff is out of the way, it is time to actually test the GLPI/Fusion Inventorysystem! Fusion has an agent for almost every operating system out there and all of them can be located on the following URL:
  1. http://www.fusioninventory.org/documentation/agent/installation/
25. However, this tutorial will walk through configuring the agent on a Linux machine as the inventory agent is already in the repositories for most distributions.
The agent will be installed on a Linux Mint 17.1 machine in this example. This is a Debian/Ubuntu based distro and it uses the ‘apt‘ meta-packager to obtain packages from the repositories.
# apt-get install fusioninventory-agent
This will install all the necessary dependencies as well as the necessary configuration file for Fusion Inventory. It will be necessary to modify the configuration file in order to tell the agent where the Fusion server resides. The configuration file is located at ‘/etc/fusioninventory/agent.cfg‘ and can be opened with any text editor.
# nano /etc/fusioninventory/agent.cfg
Just to get a machine inventoried, there is only one line that needs to be changed in this particular file and that is the ‘server =‘ line.
For this example the server line should be configured as follows (be sure to substitute the ip for the proper ip or hostname):
server = http://192.168.1.5/plugins/fusioninventory/front/plugin_fusioninventory.communication.php
Add Fusion Server IP
Add Fusion Server IP
Save the changes to this file and exit out of the text editor.
26. At this point as long as there is network connectivity to the Debian server, Fusion Inventory agent should be ready to inventory this Linux Mint machine. The command to run the agent is ‘fusioninventory-agent‘.
After running this command there wont be much, if any, output. When the command line returns to the normal prompt, it is time to check GLPI/Fusion to see if the machine was inventoried.
There are a couple of places to see whether or not the inventory worked. The first place to look is the agents view in Fusion Inventory. This will show whether or not the client actually connected to the server. To get to this view click on the following menu options: Plugins → FusionInventory → Agent.
Fusion Agent View
Fusion Agent View
27. This screen shows that the Fusion Inventory agent successfully connected to the server from the test Linux Mint machine. The other place to check is within GLPI’s Assets menu; after all this is where the inventory of machines, software, and peripherals should reside! To access this menu, simply hover over ‘Assets‘ menu in the top left of the web browser and then select ‘computers‘ when the drop down menu appears.
Inventory View
Inventory View
This will bring up the main inventory page. The newly inventoried machine will be the only entity on this page for the time being but should be there never the less.
Newly Inventoried Machine
Newly Inventoried Machine
Success! There is the Linux Mint machine with a small amount of details about the machine. To view more complex details about this machine, simply click on the name of the machine in the column on the far left.
This will present a detailed view of this particular machine’s inventory. Everything from monitors, USB drives, scanners, and software will be displayed here and any information about those devices will also be available.
Detailed Inventory View
Detailed Inventory View
At this point, GLPI and Fusion are working harmoniously and should be ready for more agents to begin transmitting information from other machines! There are currently agents available for all the major operating systems available as well as source code for those who wish to compile from source.
Thank you for sticking through this rather lengthy tutorial and hopefully this tutorial has resulted in a workingGLPI/Fusion Inventory system. Please feel free to ask any questions and best of luck inventorying assets!

Systemback: Restore Your Linux System To Previous State

http://www.unixmen.com/systemback-restore-linux-system-previous-state/

Systemback is an open source, system backup and restore application. Using Systemback, we can easily create backups of system and users configuration files. In case of problems, we can easily restore the previous state of the system. There are extra features like system copying, system installation and Live system creation.

Features

Systemback includes the following features:
  • System backup
  • System restore
  • System copy
  • System install
  • Live system create
  • System repair
  • System upgrade

Install Systemback On Ubuntu 14.04 And Previous versions

Currently, Syetmback is available only for ubuntu based systems. On Ubuntu and it’s derivatives, we can easily install it via PPA. Run the following command sequences to install Systemback on your Ubuntu system
sudo add-apt-repository ppa:nemh/systemback
sudo apt-get update
sudo apt-get install systemback

Usage

Create System Restore Point:
After installing it, launch Systemback app either from Dash or Menu.
The default Systemback main interface will look like as below.
Systemback_010
Initially, there is no system restore point. So, let us create a new system restore point by clicking on the Create New button which is found under the Point Operations section.
Now, the Systemback will create a new restore point for your system.
Systemback_011
Systemback_012
After creating the restore point, the backup will be stored in the /home/systemback/ folder. You can change the location from the Storage directory option on the top right corner of the Systemback main window. Also, the successfully created system restore points will be shown on the top left corner of the main interface.
Systemback_013
Restore the system to previous state:
Restoring to the previous state is as simple as creating restore point. Open up the Systemback main window, select any one of the system restore point, and hit the button System Restore under the Function Menu.
Systemback_001
You’ll be asked whether you want to do a full restore, system files restore, or just user(s) configuration files only. Select the option accordingly and hit the Next button.
Systemback_003
Finally, click Start button to restore your system to previous working state.
Systemback_005
System Copy:
Using System Copy feature, we can easily copy the files from one partition to another and vice versa. Use this feature with caution. Else, you’ll be ended up with data loss.
System Install:
This option will let you to create a new user with password of your choice. Also, you can change your system root user password if you want to.
Live System Create:
This is one of cool and notable feature of Systemback. Unlike other system backup and restore tools, Systemback will let you to create a live CD/DVD of your current system with or without the users data files. Later, you can use this Live CD/DVD on other system, also you can install it if you want.
Systemback_006
Systemback_007
After creating live system, convert it to ISO, and boot the ISO using CD/DVD or USB thumb drive.
Systemback_008
System Repair:
Like System Restore, this option will help you to fix your Linux desktop in case of any problems. Don’t touch this option, unless you know what you’re doing.
System Upgrade:
Using this option, you can upgrade your Linux system to the most recent version.
System upgrade_002
Exclude:
If you don’t want to include a file or folder in your restore points, you can use this feature.
Systemback_010

Removing Systemback

If you not happy, or doesn’t have necessity to keep it on your system, you can remove this software as shown below. But, I guess, this tool will definitely be an useful tool in your arsenal.
sudo apt-get purge systemback
For me, Systemback is doing the good job as it advertised, and has many additional features among other system backup and restore tools. Give it a try, you won’t be disappointed.
Cheers!

TimeShift: Restore Your Linux Desktop To Previous State

http://www.unixmen.com/timeshift-restore-linux-desktops-previous-state/


Have you ever had a situation or ever wanted to restore your Linux desktop to previous state? Windows has an excellent utility called System Restore to restore the system to previous state, but Linux doesn’t has any native application to do that. No worries, today i came up with application called TimeShift.
TimeShift is a application that provides functionality similar to the System Restore feature in Windows and theTime Machine tool in Mac OS. TimeShift protects your system by taking incremental snapshots of the file system at regular intervals. These snapshots can be restored later to bring your system to the exact state it was in at the time when the snapshot was taken.
TimeShift is something similar to applications like rsnapshotBackInTime and TimeVault but with different goals. TimeShift is designed to protect only system files and settings. User files such as documents, pictures and music are excluded.
Install TimeShift On Ubuntu 12.04/12.10/13.04/13.10
Add the TimeShift PPA with command:
$ sudo apt-add-repository -y ppa:teejee2008/ppa
Update the package lists using command:
$ sudo apt-get update
Now Install TimeShift using following command:
$ sudo apt-get install timeshift
Install TimeShift On other Linux distributions
Currently TimeShift packages are available only for Ubuntu based systems, but also the developer has developed packages for other distributions.
Before installing TimeShift, you should install the following packages depending upon your distribution.
libgtk-3 libgee2 libsoup libjson-glib rsync
Download the TimeShift packages for other distributions from the following links.
After downloading the TimeShift, install it using the following command.
Install TimeShift 32bit:
# chmod +x timeshift-latest-i386.run
# sh ./timeshift-latest-i386.run
Install TimeShift 64 bit:
# chmod +x timeshift-latest-amd64.run
# sh ./timeshift-latest-amd64.run
Launch TimeShift
Launch TimeShift either from Menu or Dash. At first launch, the application will estimate the system size for snapshot.
Create Restore point
Click Backup on the Menu bar and  take first snapshot of your system.
TimeShift v1.3.1 by Tony George (teejeetech.blogspot.in)_001After taking the first snapshot, you can schedule for automatic snapshots on a particular interval. To do that go toSettings section, enable Scheduled Snapshots and set the backup levels such as hourly, daily, weekly, monthly, boot etc.
The Snapshots will be saved on /timeshift location. TimeShift will run at 30 minute regular intervals and take backups only when needed.
After completing the first snapshot, you will have a following like screen.
TimeShift v1.3.1 by Tony George (teejeetech.blogspot.in)_002The Snapshots will be saved with exact date and time when the backup has been taken.
System Restore
You can restore Snapshots either from the running system or live cd. Restoring backups from a live system requires a reboot to complete the restore process. If your system broken or doesn’t boot in case, you can use the live cd to restore the system to a previous working state.
To restore your system to earlier state, click on the Restore button and select the snapshot.
Restore_004Also if you want to exclude some applications from being restored, you can have the option to exclude them.
Restore_005Cross platform restoration is also possible. For example, currently you are using Ubuntu 13.10 and want to try out Linux Mint 16 for a week. After one week you can switch to your old distribution Ubuntu 13.10. Please note that since installing new distributions formats root partition, so you should move the /timeshift folder to new partition.
I hope this application will help you sometimes if something went wrong on your Linux desktop. You don’t need to reinstall your system, you simply can restore your system to a previous working state without much effort using TimeShift.
Good luck!

Best Linux Distributions !!


Food Keeper App

The FoodKeeper can help consumers use food while at peak quality and reduce waste. The storage times listed are intended as useful guidelines and are not hard-and-fast rules. Some foods may deteriorate more quickly while others may last longer than the times suggested. The times will vary depending on the growing conditions, harvesting techniques, manufacturing processes, transportation and distribution conditions, nature of the food, and storage temperatures. Remember to buy foods in reasonable quantities and rotate the products in your pantry, refrigerator, and freezer.
Every year, billions of pounds of good food go to waste in the U.S. because consumers are not sure of its quality or safety. Food waste from households represents about 44% of all food waste generated in the U.S. By reducing food waste through buying appropriate quantities, storing foods properly, cooking what is needed and composting, consumers can save money and reduce the amount of food going to landfills.

YouTube Kids

https://play.google.com/store/apps/details?id=com.google.android.apps.youtube.kids

The official YouTube Kids app is designed for curious little minds. This free app is delightfully simple and packed full of age-appropriate videos, channels, and playlists. YouTube Kids features popular children’s programming, plus kid-friendly content from filmmakers, teachers, and creators all around the world.
DESIGNED FOR KIDS
We’ve taken out the complicated stuff and made an app even little ones can navigate — that means big buttons, easy scrolling, and instant full-screen.
VIDEOS KIDS WILL LOVE
Kids can enjoy favorites like Sesame Street, Thomas & Friends, and Dreamworks, online hits like Mother Goose Club, TuTiTu, and Super Simple Songs, plus anything else they’re into — music, gaming, science, crafts, and more.
VIDEOS PARENTS CAN FEEL GOOD ABOUT
We’re as focused on kids’ safety as you are, so we’ve built the YouTube Kids app to be a family-friendly place to explore.
When your child browses the app’s home screen, they’ll find a vast selection of kid-appropriate channels and playlists. When families search in the app, we use a mix of input from our users and automated analysis to categorize and screen out the videos that make parents nervous.
And for added peace of mind, parents can quickly notify YouTube if they see anything questionable directly from the app.
SETTINGS FOR PARENTS
You can turn off search for an even more contained experience. Or set the built-in timer to let your kids know when it’s time to stop watching (so you don’t have to). The app puts these settings behind a grown-ups-only lock, out of kids’ reach.
YouTube Kids. Made for curious little minds.
