|Use this tool to share your desktop with a remote guest/tech using the VNC protocol|
Krfb (server) is one of a pair of KDE programs - Krdc (client) is the other - that let you share your desktop (make it visible remotely) through the local network with another user, probably somebody like the tech downstairs who you wants to help you figure out how to do something you are having trouble with. You can call the tech on the phone and be talking with her while she assists you. The tech can even "drive" your computer if you decide to let that happen.
Krfb is a server program, serving to a client, e.g. Krdc. It must be matched by a client or "guest" program that is running on another computer. In this explanation, we will use the terms:
You will also need to refer to the Krdc page to make complete sense of this explanation.
This explanation is, therefore, from the perspective of the "host" person, sharing out, who wants help from a technician/friend and invites them to work remotely as the "guest".

Once the connection is established, you and the tech can continue to talk while either you or the guest control your computer. You or the guest tech can launch programs, minimize/restore windows, change settings, anything that you could try to do alone on your own. Because the tech is watching your screen, it will be easier to see if you missed a step or made a wrong choice. When you have the choice, make menu selections with the mouse instead of using keyboard shortcuts. The guest cannot see your keyboard or your fingers as you type, but will be able to watch as your mouse pointer moves around the screen.
Krfb also lets you send your guest an email which will include the address and password. Remember that email isn't normally encrypted. The password will be in open text on the network. Once your guest gets the email, she will be able to use Krdc to connect to your hosting computer. The guest tech or friend must be ready to receive the email invitation. Like the personal invitation, the invitation is open just for an hour.
|Note that closing the Krfb window using the "close" button does NOT stop Krfb. It continues to run as a background task. Make sure to notice the icon in the system tray, typically near the right end of the panel, When you are ready to quit sharing, right click the Krfb icon in the panel and choose the quit option. Do not try to restart Krfb through the K menu. You'll just launch another instance of the program, not connect to the one that is already running. More than one Krfb instance can make things very confusing.|
When you quit Krfb completely, the connection to your guest will be broken.
