[B]Connect to Internet from Linux via GSM Phone[/B]


Hi,

I am running fedora 6 on my laptop and I would like to connect it to internet using my GSM Phone (The GSM phone is latest 3G and has internet capability, EDGE enabled). How could I do it?

I have installed the wvdial package and is working fine. I'm able to connect my laptop to internet using a Dial-up modem but how can I connect my laptop to internet using a GSM phone?

In the wvdial.conf file for the Dial-up case I know the phone, username and password. But now for the GSM phone case what should I enter as the phone, username and password?. will the wvdial package work for GSM phone too?? If so what changes should I do??.

If anybody has connected or tried connecting a GSM phone to linux machine to access the Internet, please post your experiences and suggestions.. Your help will be very much appreciated.

Cheers!!

Here's a procedure I managed to use to get connected using a Sony K850i and a USB bluetooth dongle my laptop on Ubuntu Gutsy. I didn't try it with Hardy yet, to which I have upgraded since I documented the procedure.

1. Run:
Code:
hcitool scan
Write down the address of device, e.g. 00:1E:28:88:C1:52

2. Run:
Code:
sdptool browse 00:1E:28:88:C1:52
Look for "Dial-up Networking" in the output. This little sed command will narrow down the output to the right section, but if it doesn't work for you then you will need to check the output of the whole thing without the sed part:
Code:
sdptool browse 00:1E:28:88:C1:52 | sed -n '/Dial-up Networking/,/^$/p'
Output looks like this:
Code:
Service Name: Dial-up Networking
Service RecHandle: 0x2008004
Service Class ID List:
  "Dialup Networking" (0x1103)
  "Generic Networking" (0x1201)
Protocol Descriptor List:
  "L2CAP" (0x0100)
  "RFCOMM" (0x0003)
    Channel: 1
Profile Descriptor List:
  "Dialup Networking" (0x1103)
    Version: 0x0100
Write down the channel. In my case 1.

3. Run:
Code:
sudo vi /etc/bluetooth/rfcomm.conf
Add an rfcomm entry, using the channel from step 2, e.g.
Code:
rfcomm0 {
        bind yes ;
        device 00:1E:28:88:C1:52 ;
        channel 1 ;
        comment "My Mobile Dial-up -- for PPP" ;
}
4. Re-start bluetooth sub-system with this command:
Code:
/etc/init.d/bluetooth restart
Verify that device /dev/rfcomm0 exists and is writable.

5. Using kppp set up modem for /dev/rfcomm0 (set the fastest baud possible).

6. This step will be phone/service provider specific: On phone look in connectivity settings -> internet and select contract internet. In the options -> view it will tell you the external ID of this connection, e.g. 3.

7. Using kppp set up dialout account to number: *99***${external_id}# e.g. *99***3# for the contract internet connection described in step 6. Again this will be service provider specific. I googled about to find this number for my service provider.

8. Disable network manager / wireless / any existing connections FIRST, then dial up with kppp.

There's probably a much better way to achieve what I did in the last post, but there it is for what it's worth.

I devised the procedure with a mixture of reading the manual pages, and googling for tutorials and so on. Now I look at it and wonder what on Earth it's doing. I hope it's helpful for you, but please don't ask me to explain exactly how it works.

Hi Matthew,

Thank you so much for taking your time to help me with the procedure.. I got that working.. Now I'm able to connect to the internet using a GSM phone.. I will never ask you to explain what it is as long as it is working

Do you know how I can connect to the internet using a GSM modem from my linux machine?

Cheers!!

I'm confused. You got it working, but you still need to know how to get it working?
