View Full Version : [ubuntu] Cannot open Gnome-ppp

July 6th, 2009, 10:54 PM

I am attempting to set up an internet connection using my mobile phone via Bluetooth. I have seen it done before, so it shouldn't be too difficult. I am attempting to use the tutorial outlined at http://wiki.glug.org.za/index.php/Networking/Internet/Bluetooth_Dialup

However, when I attempt to run Gnome-ppp, I get the following message:

$ gnome-ppp
WVCONF: /home/etienne/.wvdial.conf
Segmentation fault

And when I attempt to run wvdial, the following happens:

$ wvdial
--> WvDial: Internet dialer version 1.60
--> Cannot open /dev/modem: No such file or directory
--> Cannot open /dev/modem: No such file or directory
--> Cannot open /dev/modem: No such file or directory

I do not have a modem attached, nor an inbuilt one. I want to setup Gnome-ppp to use my mobile phone via bluetooth rather than a modem. I know it is possible, but I am struggling.

Thanks in advance for any help...

Hi etienne@Rofti, according to the link you supplied in your post, you must gain a bluetooth connection with your phone as device: /dev/rfcomm0 By default wvdial uses /dev/modem which can be changed (and all other connection parameters) with:
sudo gedit /etc/wvdial.conf
In this parameter file you must edit all data to appropriate with your hardware and your provider's data connection. A typical /etc/wvdial.conf could be:
[Dialer Defaults]
Modem = /dev/rfcomm0
Modem Type = Analog Modem
ISDN = 0
Baud = 460800
Dial Attempts = 1
Username = user
Password = pass
Init1 = ATZ
Init2 = AT&F &D2 &C1
Init3 = AT+CGDCONT=1,"IP","internet"
Phone = *99***1#
Stupid Mode = 1

If your phone has various setup profiles, set it to modem.

Connect using sudo wvdial from a terminal window. Most times the system cannot co-operate with wvdial and seems to be offline, so untick "work offline" from firefox (ALT-F W).

I cannot help you with the "Segmentation fault" error of gnome-ppp.

Post any new message to follow up.
