You can change your password by editing your own user in the administration screen.

=== Deploying Guacamole ==Access Outside the Network =To deploy If you want Guacamole's web interface to be accessible outside of your LAN you will have to forward a random, you must make two symbolic links: one effectively copying the web application unused port (now located at /var/lib/guacamole/guacamole.war1111, for example) into the directory Tomcat monitors for web application deployment, and the other effectively copying the configuration file, guacamoleto port 8080 in your router.properties, into the Tomcat's classpath, such that Guacamole can find it once it runs. This must be done as root:{{Code|Code = # ln -s /var/lib/guacamole/guacamole.war /var/lib/tomcat6/webapps# ln -s /etc/guacamole/guacamole.properties /usr/share/tomcat6/lib}}

Start GuacamoleIf you do not add 's service{{Code|Code = service guacd start}}'/guacamole'' to your url, you will see a blank page since you did not specify which application in Tomcat you wanted to access.

Restart Apache== Guacamole RDP Connections to Windows Computers ==After you have login 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.  Below are some VERY basic settings for an RDP connection in Guacamole:  Name: whatever you want to call it (One can put "RDP" within the name so as to differentiate between connections types in the list) Location: ROOT Protocol: RDP  Maximum number of connections: 2 Maximum number of connections per user:2  Host Name: The fixed IP address of the computer to which you wished to connect. (For example ''192.168.1.10'') All the other settings are left either blank or as they were. Note: Using RDP, only one device at a time can be logged in under a specific user. If you are logging into a Windows computer by the user "Fred" by RDP using Guacamole, any other device signed in as "Fred" will be logged out. The side effect is that, when using RDP, a technician (using Guacamole) and client (on their Window computer) cannot see the same active desktop simultaneously. As a workaround, one can set up a VNC and an RDP connection for each Windows computer. RDP can be quicker 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. 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. == Guacamole VNC Connections to Computers =="In computing, Virtual Network Computing (VNC) is a graphical desktop sharing system that uses the Remote Frame Buffer protocol (RFB) to remotely control another computer. It transmits the keyboard and mouse events from one computer to another, relaying the graphical screen updates back in the other direction, over a network."''2'' 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 user's desired specifications. In this publication, we will use a Windows based client and UltraVNC software, though this is by no means prescriptive for everyone. ===Guacamole VNC Connections to Windows Computers ==={{Code| Code = sudo ===UltraVNC Settings for Windows====Be sure to install UltraVNC to run as a service httpd restart}}on the client system. Once UltraVNC is installed on the Windows computer, right-click on the system tray icon and choose "Admin Properties" from the menu that comes up. Set the following values:  Display Number or Ports to use: Select Ports and set Main and Http so something specific (e.g. 5904, 5804) Authentication: Set both the VNC Password and the View-Only Password. (Write them down. You will need it later.) Click "OK" and then give permission for the program to make changes to your system. ====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.
