Use Nokia E65 as GPRS modem in Ubuntu 8.04

A short description about how to use a Nokia E65 as a GPRS modem in Ubuntu 8.04.

Install the needed software packages:

sudo apt-get install bluez bluez-utils wvdial

Enable bluetooth on your phone, scan for it and copy the address for your phone.

hcitool scan

The next step is to find the channel for the phone's dialup service. Run

sdptool browse xx:xx:xx:xx:xx:xx

where xx:xx:xx:xx:xx:xx is the address found in the previous step. Look for "Service Name: Dial-Up Networking", and note the channel number.

The phone now has to be bound as a rfcomm device, which is configured in /etc/bluetooth/rfcomm.conf. Add

rfcomm4 { bind yes; device xx:xx:xx:xx:xx:xx; channel 2; comment "Serial Port"; }

to the file with the numbers found above.

Now make a configuration file for wvdial

sudo gedit /etc/wvdial.conf

with this content:

[Dialer Defaults]
Modem = /dev/rfcomm4
Baud = 115200
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Init3 = ATM0
Init5 = AT+CGDCONT=1,"IP","internet"
ISDN = 0
Modem Type = Analog Modem
Phone = *99***1#
Username = foo
Password = bar

Thats it. I use the commands below to start the connection. First shut down wlan0, which should not be necessary, but sometimes DNS won't work if wlan0 is searching for access points. I restart bluetooth in order to make sure the phone is bound, and finally, I run wvdial to start the connection.

sudo ifconfig wlan0 down
sudo /etc/init.d/bluetooth restart
sudo wvdial

Ubuntu Ibex, Fullrate, Huawei E220 USB Modem

I just got my "Fullrate Mobile Broadband Testpilot package", and a now writing this post on a mobile broadband connection. The purpose is to explain, how simple it is to make the USB modem work.

As far as I can see, Ubuntu lacks the possible to tell the modem the PIN, which makes the SIM card useless. To get round this missing feature, just put the SIM card into you cellphone, enter the PIN and disable the PIN under the security settings. This makes it possible for anyone to use your SIM, so guard it with you life! :)

Now put the SIM back in the modem, and connect it to your computer. The below pop up will show up, and you just have to click Config. (If it do not show up, right click on the Network Manager and select Edit Connections.)

Click Next, and select TDC as Service Provider (Fullrate uses TDCs net), click Next again, and give the connection a name and then click Apply.

Now the system should connect you, if you have coverage, and this pop up will appear

Very simple!!! :)

The connection is quite good, and the speed is as promised. Fullrates speedtest at http://speedtest.fullrate.dk/ gives 1.15Mps, while the upload is at 0.25Mps.

The ftp servertest at http://www.fullrate.dk/support/hastighed/ do not work, which might be because the server only allow Fullrate connections, while this is basically a TDC connection.

Downloading a part of an Ubuntu image from HEAnet Ireland gives an average of 115K/s, which is the normal, according to http://www.fullrate.dk/support/hastighed/

Maybe a little to early to say anything works. After 40 minutes the modem lost connection for 5 min, before getting on-line again.

Hvorfor videresender man kædemails?

Det hænder, at der dumper mails ind i indbakken med emner som "Facebook er overbefolket" og "Til sommer vil msn koste penge". Beskederne kommer typisk fra nogen man kender, og modtagerfeltet indeholder hele afsenderens adressekartotek.

Der er mange ting i denne verden jeg ikke forstår, men hvorfor folk videresender disse beskeder overgår dog det meste.

Lad os tage Facebook som eksempel. Som standard modtager man en mail fra Facebook, stort set lige meget hvad der sker på ens profil - ergo har Facebook rig mulighed for at kontakte dig. Hvordan kan man så tro på, at de skulle vælge at sende så vigtig en besked ud som et kædebrev, på folks Wall eller via private beskeder?

Dernæst vil Facebook da aldrig klage over at have for mange brugere. Hvad skulle formålet være? Det svarer til, at man er i Brugsen, og bliver smidt ud fordi bestyreren synes der er for mange kunder!

Kom nu ind i kampen!
