'''Krfb''' is a server program. It must be matched by a client or "guest" program that is running on another computer. In this explanation, we will use the terms:
:*Start '''Krfb''': <menuchoice>K Menu (Kickoff) -> Applications -> Internet -> Desktop Sharing (Krfb)</menuchoice>
:*啟動Krfb: K 菜單(Kickoff) -> 應用程序-> Internet -> 桌面共享(Krfb)
:*Call the guest/tech/friend you want to invite.
:*聯繫你要邀請的客戶機/技術人員/好友。
:*Click the "New Personal Invitation" button
:*點擊"新建個人邀請"按鈕
:*Tell the guest the address of your computer which is shown in the '''Krfb''' window. (Mention the need for the port number which is required by '''Krfb''')
:*告訴客戶機你的電腦地址(顯示在Krfb 窗口上)。 (告訴對方 Krfb 要求的端口號)
:*Carefully tell the guest the password, emphasizing the capital and lower case letters and the dash.
:*謹慎的告訴客戶機密碼,注意大小寫和破折號。
:*When the guest enters the correct password you will see a popup window in which you can approve the connection by clicking appropriate button. (You can really wreck your relationship with the tech, by rejecting the connection, but that wouldn't be too good.)
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.}}
注意使用“關閉”按鈕關閉Krfb 窗口並不會停止Krfb。它會繼續在後台運行。注意系統托盤的圖標,常靠近面板右端,當你準備退出共享,右擊面板上的Krfb 圖標,選擇「退出」選項。不要試著通過 K 菜單重啟 Krfb。你這樣只會啟動另一個Krfb 實例,不會連接到已經運行的那個實例。 Krfb 實例多於1個的話會讓事情變得很混亂。

When you quit '''Krfb''' completely, the connection to your guest will be broken.
當你完全退出Krfb,與你的客戶機的連接便會中斷。
Notes:
注意:
:* If you have an active ''firewall'' running on the "host" machine, you will need to open port 5900. If a firewall is blocking port 5900, the process of sharing at the host end will appear to work fine, but the guest will get a message saying the server wasn't found. It is difficult to determine whether the connection failed because of a mistyped address or a firewall. It may make sense to plan ahead and have your first sharing session with the tech in the same room with you. You and she can work through any difficulties about the connection and then do help sessions remotely after that.
:* If you close the '''Krfb window''', it does NOT stop the program. To quit '''Krfb''', right click the program's icon in the system tray and choose the option to quit.
:* Turning off your host computer does NOT stop '''Krfb'''. It will pop up at the next restart. You must quit through the system tray icon.
:*關機並不會停止 Krfb,它在下次開機時會彈出來。你必須通過系統托盤圖標退出程序。
:* Though it is possible to use '''Krfb'''/'''Krdc''' across the Internet, cable modem/routers at the host "end" must be set to forward port 5900 and there are similar issues trying to cross corporate firewalls.
