Ibland avslutar du upp någonstans med din bärbar dator var du precis inte kan finna any öppna WiFi. Luckily har du en Nokia N95 och en Bluetooth adapter. Förmiddag som I går att visa dig hur man tjudrar din N95 till din bärbar dator via Bluetooth ömt ställe och smutsar ner, befaller fodrar långt, as well as den mer nätt GUIEN långt. I dessa förmiddag rinnande Fedora 9 för exempel I och Gnome.
Varning: Du önskar antagligen endast att göra denna, om du har anständiga data att planera. Att använda data 3G kan resultera i en mycket stor räkning!
- Det första tinget som du behöver att göra, är att se till din N95 paras med din bärbar dator. Detta är långt lättare, än jag förväntade. Som börja para från ditt ringa och att skriva in den samma passkeyen på både ringa och datoren, när du meddelas, så länge som du har gnomen-bluetooth att paketera installerat, är den så enkel. Du behöver också att ha pppen att paketera, och de wvdial paketerar installerat. Om du inte, kan du enkelt köra, som rotar i ett slutligt fönster, yumen installerar wvdial ppp (eller använd allt vad paketerar, chefen kommer med din Linux distro).
- , att öppna ett slutlig fönster och körning, nu båda apparater paras hcitoolbildläsning för att upptäcka ditt ringer det Bluetooth MACet address. Detta delar upp applicerar till den båda befalla fodrar och GUI-delar av denna tutorial.

Now we move on to the quick and dirty command line setup. Feel free to skip to the GUI setup below if you aren’t very comfortable with the command line.
Command Line Method
GUI Method
- Edit /etc/wvdial.conf and make it look like this:
- I’m using Rogers Wireless in Canada and the above is the minimum configuration that works for me. Literally Username = user and Password = pass. You may need to make changes to the Username, Password, and Phone lines. Contact your wireless provider for the correct details.
- I also had to create a script called /etc/ppp/ip-up.local to make the automatic DNS configuration work. Here’s my ip-up.local:
- Unfortunately I have not been able to connect as a normal user in this configuration so you’ll have to connect as root.

- You can verify that you are online by switching to a new terminal window and running ifconfig.

Now, if all that command line stuff scares you, here’s how to make it work using Gnome’s GUI:
- Click System -> Administration -> Network
- You will be asked to enter your root password. Enter it and click OK.
- Now you can see a list of installed network devices. Click on the Hardware tab.
- Now click the New button, select Modem, and click OK.
- Change the Modem Device to /dev/rfcomm0. If /dev/rfcomm0 is not available in the list, just type it in. Click OK.
- Now click the Devices tab.
- Click the New button, select Modem connection, and click Forward.
- All I needed to do to make my Rogers Wireless connection work was enter *99***1# as the Phone Number, user as the Login Name, and pass as the Password. I also chose to name this connection Bluetooth. Click Forward.
- I left these options at their defaults. Click Forward.
- We’ve finished creating the connection. Click Apply.
- Click the X in the top right corner to close this window.
- Click Yes to save the changes.
- Click OK. No, we won’t need to restart the computer.
- So, let’s use our newly created connection. Click System -> Administration -> Network Device Control.
- Select the Bluetooth connection you just created and click Activate.
- Notice how the Bluetooth connection has changed from Inactive to Active.
- Open Firefox and visit http://www.simplehelp.net.
- When you are finished online, go back to the Network Device Control window, select the Active Bluetooth connection and click Deactivate.
- Verify that the Bluetooth connection is indeed Inactive, then close the Network Device Control window.
- Some of you may be wondering why I chose not to use Network Manager. It’s quite simply due to the fact that mobile broadband support in Network Manager is in it’s infancy and I found it to be virtually unusable. Once Network Manager’s mobile broadband support becomes better, I’ll rewrite this tutorial based on it.
