{{NeedsUpdateMessageBox|backgroundcolor = #faa|image =Warning.png|heading =WARNING|message = This is recommended only for advanced users, proceed with caution.}}== What is Guacamole? == [https://guacamole.incubator.apache.org/ Guacamole ] is an HTML5 remote desktop gatewaythat can be installed on Amahi 9 (Fedora 23). This guidance may work with other Amahi versions with some modification.
Guacamole provides access to desktop environments using remote desktop protocols like VNC and RDP. A centralized server acts as a tunnel and proxy, allowing access to multiple desktops through a web browser.
No browser plugins are needed, and no client software needs to be installed. The client requires nothing more than a web browser supporting HTML5 and AJAX.
== Installing Guacamole on Amahi ===== Dependencies ===*tomcat6 *libvncserver *freerdp (This is official on the Guacamole siteREF: [http://www. Fedora 14 will not support Freerdp 1tecmint.0 or higher, thus RDP protocol in com/guacamole-access-remote-linux-windows-machines-via-web-browser/ Setting Up Web-Based Guacamole is not available. Leave freerdp out of the code below if you are running Fedora 14.)*libvorbisTool to Access Remote Linux/Windows Machines]
In terminal, = Install Guacamole =<div style="border: 1px solid #A3B1BF; padding: .8em 1em; background-color: #E6F2FF; margin: 0px 1em;">'''WARNING:''' All commands in this tutorial are executed as <code>root, install dependencies </code> (or precede with the following:<code>sudo</code>).</div>
{{Code|
Code = $ su
Password:
# yum install tomcat6 libvncserver freerdp libvorbis
}}
We have created a bash script to make installation simple or you can manually install using the guidance below. You '''MUST''' complete the [[Guacamole#Create Amahi Web App|Create Amahi Web App]] step prior to executing the following: wget <nowiki>https://www.dropbox.com/s/4hadafih8ahuj2n/install-guacamole.sh</nowiki> chmod 755 install-guacamole.sh ./install-guacamole.sh Do NOT use this script on anything less than Amahi 9 / Fedora 23 unless you edit it first to match your systems' requirements. (See [[Guacamole#Install Dependencies|Install Dependencies]] to learn what changes are necessary.) === Preparing Create Amahi =Web App ==Login to your Amahi Dashboard and choose "Set Up" install the Amahi [https://www.amahi.org/apps/web-apps Web Apps] plug-in the upper right.Ensure you '''enable''' [[Advanced Settings]]. 
Now select the "Apps" tab.
Click on "Webapps" and on the page that comes up choose the "New Web App" button at the bottom.
Fill in the name (guacamole) and leave everything else as it is.
* NoteEdit ''####-guacamole.conf'' in '''/etc/httpd/conf.d''' (replacing #### with the appropriate number): vi /etc/httpd/conf.d/####-guacamole.conf Right below the ''ServerAlias'' line, add the following: ProxyPass / <nowiki>http://localhost:8080/guacamole/</nowiki> ProxyPassReverse / <nowiki>http://localhost: If 8080/guacamole/</nowiki> Again, if you use vi for creating this file, press the <i>Esc</i> key to get back in command mode and <i>:wq</i> to write the changes and quit vi. Restart Apache systemctl restart httpd == Install Dependencies ==Due to the Fedora 23 ''freerdp'' packages being unstable, we must use the CentOS stable version. (Do not do not see this if you are installing on Fedora 21 or below) To install, execute the following:<pre>wget https://www.dropbox.com/s/p2uc1rcpckky75v/libxkbfile-1.0.8-5.el7.x86_64.rpmwget https://www.dropbox.com/s/0tjm7q93z9pw0hj/freerdp-libs-1.0.2-6.el7_2.1.x86_64.rpmwget https://www.dropbox.com/s/aysml7coehz0hqi/freerdp-devel-1.0.2-6.el7_2.1.x86_64.rpmrpm -Uvh libxkbfile-1.0.8-5.el7.x86_64.rpmrpm -Uvh freerdp-libs-1.0.2-6.el7_2.1.x86_64.rpmrpm -Uvh freerdp-devel-1.0.2-6.el7_2.1.x86_64.rpm</pre>  Now install the Fedora dependencies:For Fedora 23 or newer (Fedora 21, substitute <code>yum</code> for <code>dnf</code> and add <code>freerdp-devel</code> to the list of dependencies): dnf install tomcat gcc cairo-devel libjpeg-devel libpng-devel uuid-devel pango-devel \ libssh2-devel libtelnet-devel libvncserver-devel pulseaudio-libs-devel openssl-devel \ libvorbis-devel libwebp-devel dejavu-sans-mono-fonts terminus-fonts terminus-fonts-console == Configure MySQL Authentication ===== Install MySQL Authentication Module ===Create a working directory and move there mkdir -p /var/hda/web-apps/guacamole/sqlauth && cd /var/hda/web-apps/guacamole/sqlauth Download Guacamole's authorization module wget <nowiki>http://sourceforge.net/projects/guacamole/files/current/extensions/guacamole-auth-jdbc-0.9.9.tar.gz</nowiki> Unpack it tar -zxf guacamole-auth-jdbc-0.9.9.tar.gz Download MySQL and Java Connector wget <nowiki>http://dev.mysql.com/get/Downloads/Connector/j/mysql-connector-java-5.1.38.tar.gz</nowiki> Unpack it tar -zxf mysql-connector-java-5.1.38.tar.gz Create directories for the extensions in Tomcat's folders mkdir -p /usr/share/tomcat/.guacamole/{extensions,lib} Move the modules to their respective directories. mv guacamole-auth-jdbc-0.9.9/mysql/guacamole-auth-jdbc-mysql-0.9.9.jar /usr/share/tomcat/.guacamole/extensions/ mv mysql-connector-java-5.1.38/mysql-connector-java-5.1.38-bin.jar /usr/share/tomcat/.guacamole/lib/  Restart MariaDB systemctl restart mariadb === Create the Database === hda-create-db-and-user guacdb === Configure Database Settings ===Create a directory for the configuration file. mkdir -p /etc/guacamole/ Create a file called "Webappsguacamole.properties" option under "Apps" then in that directory vi /etc/guacamole/guacamole.properties Press the <i>i</i> key to begin inserting text into the guacamole.properties file and include the following contents: # MySQL properties mysql-hostname: localhost mysql-port: 3306 mysql-database: guacdb mysql-username: guacdb mysql-password: guacdb # Additional settings mysql-default-max-connections-per-user: 0 mysql-default-max-group-connections-per-user: 0 If you need use vi for creating this file, press the <i>Esc</i> key to get back in command mode and <i>:wq</i> to activate "Advanced Settings" under write the "Settings" tab of your Amahi dashboardchanges and quit vi.
=== Downloading the Binary Packages ===Now create a symbolic link of this file for TomcatGo to http: ln -s /etc/guacamole/guac-devguacamole.orgproperties /usr/share/tomcat/ and choose from the table the binary packages for your system. For '''Fedora 14''', I chose the '''Fedora 15''' packages and they worked flawlessly.guacamole/
=== Installing Load Guacamole Data ===In terminal, The schema for MySQL was downloaded in the previous process.Just change directories to where the packages downloaded and execute the following as root:files location{{Code|Code = # tar cd /var/hda/web-xzf apps/guacamole/sqlauth/guacamole-0.8.0-fedoraauth-15-i386.tar.gz# cd guacamolejdbc-0.89.0-fedora-15-i3869/mysql/schema/# rpm -i *and run the following command: cat .rpm}}/*Be aware that you may have to adjust the above code to match the file name you downloaded.sql | mysql -uroot -p guacdb
=== Setting up MySQL Authentication ======= Making ::'''WARNING:''' Please see [[Database Root Password]] for the Directory ====As root, create the "classpath" directory{{Code|Code = mkdir /var/lib/guacamole/classpath}}appropriate login password.
==== Installing MySQL Authentication Module ==Install Guacamole Server ==Download Guacamole uses "guacd", a Guacamole server and a Guacamole Client for users to connect to the MySQL Authentication Modulehttp://sourceforge.net/projects/guacamole/files/current/extensions/guacamole-auth-mysql-0.8.0"guacd" server.tar We first install Guacamole Server.gz/download
Move to the directory containing the download and unpack the downloadChange Directories cd /var/hda/web-apps/guacamole
{{Code|Code = # tar -xzf Download Guacamole Server wget <nowiki>https://sourceforge.net/projects/guacamole/files/current/source/guacamole-auth-mysqlserver-0.89.09.tar.gz}}*Be aware that you may have to adjust the above code to match the file name you downloaded.</nowiki>
Unpackage it
tar -xzf guacamole-server-0.9.9.tar.gz
Copy all of the ".jar" files in the /lib of the downloaded file Move to the classpath Guacamole source code directory you created.{{Code|Code = cp -r /whereever/you/downloaded/it/ cd guacamole-auth-mysqlserver-0.8.0/lib/*9.jar 9/var/lib/guacamole/classpath}}
You need one more "Configure, make and install it. .jar" file (MySQL Connector/configure --J)that is not included in the guacamolewith-authinit-mysql module. You can get it here: http:dir=/etc/devinit.mysql.com/downloads/connector/j/d make make install ldconfig
Move to the == Install Guacamole Client ==Create a new directory containing the download and unpack the downloadmove to it. mkdir -p /var/lib/guacamole && cd /var/lib/guacamole/

Create a symbolic link of the file for Tomcat.
ln -s /var/lib/guacamole/guacamole.war /var/lib/tomcat/webapps/
Copy mysql-connector-java-5.1.23-bin.jar to the classpath == Update Amahi Web App Files ==Create Symbolic links between guacamole in Tomcat and Amahi's web app directory you created.{{Code|Code = cp ln -r s /whereevervar/youlib/downloadedtomcat/itwebapps/mysql-connector-java-5.1.25guacamole/mysql-connector-java-5.1.23-bin.jar * /var/libhda/web-apps/guacamole/classpath}}html
==== Making Make sure the MySQL Tables ====Now we need to create a MySQL Table that Guacamole can use{{Code|owner of all the file is ''apache'' and the group is ''users''.Code = $ mysql -u root chown -pEnter passwordR apache: default for Amahi is users /var/hdamysql> CREATE DATABASE /web-apps/guacamole;Query OK, 1 row affected (0.00 sec)
mysql> CREATE USER 'guacamole'@'localhost' IDENTIFIED BY 'some_password';== Start Guacamole Server ==Query OK, 0 rows affected (0Restart Tomcat.00 sec) ​systemctl restart tomcat

mysql> FLUSH PRIVILEGES;Configure Guacamole Server to start at boot.Query OK, 0 rows affected (0.02 sec) systemctl enable tomcat chkconfig guacd on
mysql> quitBye= Log In to Guacamole =}}The database and user You can be named whatever you like, but access the above coding steps refer to both as "web login screen for Guacamole from computers in the network via '''<nowiki>http://****:8080/guacamole". Naturally, you should choose a real password for </nowiki>''' (Where the ''****'' is the IP address of your user rather than the string "some_password" shown aboveAmahi server).
==== Running The default user name/password is ''guacadmin''/''guacadmin''. You can change your password by editing your own user in the SQL scripts ====administration screen.
The SQL scripts that create = Access Outside the database schema and default administrator user are included in the guacamole-auth-mysql-0.8.0 archive Network =If you downloaded within the schema/ directory. Change directories want Guacamole's web interface to the guacamole-auth-mysql-0.8.0 archive.{{Code|Code = cd /whereever/be accessible outside of your LAN you/downloaded/it/guacamole-auth-mysql-0.8will have to forward a random, unused port (1111, for example) to port 8080 in your router.0}}
The scripts are named such that they can be run in order with one commandThen when you access Guacamole from outside your LAN you will need to add ''/guacamole'' to the end of your url. (<nowiki>http: $ cat schema/*/servername.sql | mysql -u root -p yourhda.com:1111/guacamole Ender password: Amahi default is hdaTo get all of the MySQL code to appear on this page I had to format it as a block quote. You do run the above in terminal</nowiki>).
==== Configuring Guacamole If you do not add ''/guacamole'' to Use MySQL Authentication ====You your url, you will need see a blank page since you did not specify which application in Tomcat you wanted to edit /etc/guacamole/guacamoleaccess.properties
Start at the line "# Hostname The safest and port of guacamole proxy" most secure method to access Guacamole is using [https://www.amahi.org/apps/openvpn OpenVPN] and replace everything below it with this:an [[OpenVPN_clients|OpenVPN client]] from a smart phone, tablet, or computer.

Click on the Connections tab on the settings page. Click the "New Connection" button.  Below are some VERY basic settings for an RDP connection in Guacamole: /var/lib/guacamole/classpath # MySQL propertiesName: whatever you want to call it (One can put "RDP" within the name so as to differentiate between connections types in the list) mysql-hostnameLocation: localhostROOT mysql-portProtocol: 3306RDP  mysql-databaseMaximum number of connections: guacamole2 mysql-usernameMaximum number of connections per user: guacamole2  mysql-passwordHost Name: some_passwordThe fixed IP address of the computer to which you wished to connect. (For example ''192.168.1.10'')
Use All the real password you chose when creating the MySQL database for the Guacamole database in place of the string "some_password" other settings are left either blank or as shown abovethey were.
=== Deploying Guacamole ===To deploy GuacamoleNote: Using RDP, you must make two symbolic links: only one effectively copying the web application (now located device at /var/lib/guacamole/guacamolea time can be logged in under a specific user.war) If you are logging into a Windows computer by the directory Tomcat monitors for web application deploymentuser "Fred" by RDP using Guacamole, and the any other effectively copying the configuration filedevice signed in as "Fred" will be logged out. The side effect is that, guacamole.propertieswhen using RDP, into a technician (using Guacamole) and client (on their Window computer) cannot see the Tomcat's classpathsame active desktop simultaneously. As a workaround, such that Guacamole one can find it once it runsset up a VNC and an RDP connection for each Windows computer. This must RDP can be done as root:{{Code|Code = # ln -s /var/lib/guacamole/guacamole.war /var/lib/tomcat6/webapps# ln -s /etc/guacamole/guacamolequicker and more fluid so use RDP when working alone and VNC when one needs to see what is currently happening on a Users computer under their account.properties /usr/share/tomcat6/lib}}
Restart Tomcat{{Code|Code = service tomcat6 restart}}Special Note: Once settings are in place, users can click on their User Name in the upper right corner and choose "Home" from the drop-down menu to return to the home screen and use pre-configured connections.

Now In order to connect through Guacamole to a client device by VNC, one needs to install VNC client software on the device and configure it to the tomcat6 user's desired specifications. In this publication, we will use a Windows based client and guacd services to run automaticallyUltraVNC software, though this is by no means prescriptive for everyone.

====Guacamole Settings to Connect to the Windows client====
After logging in to Guacamole click on your login name in the upper right .
In the drop-down menu choose "Settings."
Click on the Connections tab on the settings page.
Click the "New Connection" button.
As root, create .htaccess file Below are some VERY basic settings for a VNC connection in /var/hda/web-apps/guacamole/html{{Code|Code = # cd /var/hda/web-apps/guacamole/html# gedit .htaccess}}Guacamole:

Password: The VNC Password set earlier in the Windows UltraVNC client software.conf, change "AllowOverride AuthConfig" to "AllowOverride FileInfo Limit Options Indexes"
== Logging In to Guacamole ==You can access All the web login screen for Guacamole from the server at http://127.0.0other settings are left either blank or as they were.1:8080/guacamole
The default user is "guacadmin"Special Note: Once settings are in place, with users can click on their User Name in the default password of upper right corner and choose "guacadminHome". You can change your password by editing your own user in from the drop-down menu to return to the administration home screenand use pre-configured connections.
With everything configured correctly you should be able to access the web login screen through Amahi at http== References ==''1'' https://guacamoleen.yourhdanamewikipedia.com:8080org/guacamolewiki/Remote_Desktop_Protocol
== Port Forwarding ==If you want Guacamole's web interface to be accessible outside of your LAN you will have to forward a random'2'' Richardson, T.; Stafford-Fraser, Q.; Wood, K. R.; Hopper, unused port A. (1111, for example1998) to port 8080 in your router. Then when you access Guacamole from outside your LAN you will need to add "/guacamoleVirtual network computing" to the end of your url(PDF). (serverblahblahIEEE Internet Computing.yourhda2: 33.comdoi:111110.1109/guacamole) If you do not add "/guacamole" to your url, you will see a blank page since you did not specify which application in Tomcat you wanted to access4236.656066.
