Krfb

Brug dette redskab til at dele dit skrivebord med en bruger, som arbejder fra en anden maskine ved brug af VNC-protokollen

Krfb er den ene af to KDE programmer (Krdc er det andet), som lader dig dele dit skrivebord gennem det lokale netværk med en anden bruger, for eksempel en supporter, som skal hjælpe dig med at finde ud af, hvordan du gør et eller andet, som du har problemer med. Du kan ringe supporteren op, og tale med hende mens hun hjælper dig. Supporteren kan endda "overtage" din maskine, hvis du vælger at tillade det.

Krfb er et serverprogram. Det skal arbejde sammen med en klient (et "gæsteprogram"), som kører på en anden computer. I denne forklaring vil vi bruge to begreber:

• gæst for den afsides bruger og maskine, som du vil invitere
• vært for din maskine og dig, som den der deler sit skrivebord

Du må også læse siden om Krdc for helt at forstå denne forklaring.

Denne forklaring er fra "værtens" prespektiv, altså den, der deler sit skrivebord og ønsker hjælp fra en tekniker eller ven og inviterer hende til at arbejde fra en anden computer som "gæst".

Skridt til opkobling ved brug af en personlig invitation

• Start Krfb: Startmenu > Programmer > Internet > Desktopdeling (Krfb)
• Ring til gæsten/teknikeren/vennen, som du vil invitere
• Klik på knappen Ny personlig invitation
• Opgiv din computers adresse til gæsten; adressen vises i Krfbs vindue. (Opgiv også port-nummeret; det skal Krfb bruge).
• Opgiv adgangskoden til gæsten - vær omhyggelig med store og små bogstaver og bindestreger
• Når gæsten skriver den korrekte adgangskode, dukker der et vindue op, hvor du kan godkende forbindelsen ved at klikke på den relevante knap. (Du kan virkelig ødelægge dit forhold til teknikeren, hvis du klikker på den forkerte knap. Det ville ikke være så godt.)

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.

Connecting using Email Option

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.

Warning

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.

Notes:

• 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.
• 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.
• About information (version, etc.) is found by right clicking the system tray Krfb icon.
• 'If the guest user clicks the Print Screen key, the screen capture tool Ksnapshot will launch on both guest and host.
• The VNC protocol does NOT enable file sharing between guest and host. You will need to transfer files saved on either computer by some other method.
