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.
当你完全退出 Krfb,与你的客户机的连接便会中断。
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.
:*关机并不会停止 Krfb,它在下次开机时会弹出来。你必须通过系统托盘图标退出程序。
:* 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.
