Nokia N95 bluetooth teethering with T-Mobile under Linux and Delll Latitude D630

Spent a bit of time to configure my Nokia mobile to teethering wih my Linux and T-Mobile. Here is some steps that may help the others :

  • If you don’t have that blue bluetooth led switched on on your Dell Latitude D630 Laptop you have to enable it. I haven’t find any way to do that via the Linux Kernel module but with Windows under Vmware Player (3.0) enabling Bluetooth and installing the driver (manually not via the setup.exe) enabled bluetooth.
  • Switched on bluetooth on the Phone and attached to the laptop via gnome bluetooth applet thingy.
  • Get my phone device number from hcitool scan.
  • And did this (as root) :

cat </etc/bluetooth/rfcomm.conf
# RFCOMM configuration file.

rfcomm0 {
# Automatically bind the device at startup
bind yes;

# Bluetooth address of the device

# RFCOMM channel for the connection
channel 4;

# Description of the connection
comment “Nokia N95″;

/etc/init.d/bluetooth restart

cat </etc/ppp/chat-tmobile
SAY ‘Calling t-mobile…\n’
“” ‘ATZ’
OK ‘ATE0V1&D2&C1S0=0+IFC=2,2′
SAY ‘Modem reset.\n’
SAY ‘Setting APN…’
OK ‘AT+cgdcont=1,”IP”,””‘
SAY ‘APN set\n’
SAY ‘Dialling…\n’
OK ‘ATDT*99#’

cat </etc/ppp/peers/t-mobile
idle 7200
user “user”
password “pass”
ipcp-restart 10
lcp-echo-interval 65535
lcp-echo-failure 10
lcp-max-configure 10
connect “/usr/sbin/chat -v -f /etc/ppp/chat-tmobile”

Under Debian distros you can enable the connection with the command ‘pon t-mobile’ or you for the others can do via the manual way with the command ‘pppd call t-mobile’.

FTP server for Cloud Files

I have just committed an experiment of a FTP Server answering to Cloud Files. It act completely transparently to be able to use any FTP Client to connect to cloud-files.

There is probably a couple of bugs there but the basis of it seems to be working, please let me know if you find any problems with it.


By default it will bind to port 2021 and localhost to be able to be launched by user which can be changed via the command line option -p. The username password are your API Username and key.

Manual Install

FTP-Cloudfs require the pyftpdlib which can be installed from here :

and python-cloudfiles :

you can then checkout FTP-Cloudfs from here :

The way to install python package is pretty simple, simply do a python install after uncompressing the tarball downloaded.

Automatic Install:

You can generate a debian package directly from the source if you have
dpkg-buildpackage installed on your system. It will give you a nice
initscripts as well to start automatically the ftp cloudfs process.


Albeit I am working for Rackspace Cloud this is not supported by
Rackspace but please feel free to send a comment here if you have any

Accessing to Rackspace Cloud Files via servicenet (update)

Last week I have posted an article explaining how to connect to Rackspace Cloud Files via Rackspace ServiceNET but I actually got it wrong as pointed by my great colleague exlt so I had to take it down until figured out how to fix it.

I have add that feature properly to the PHP and Python API in version 1.5.0 to add a ‘servicenet’ argument to the connection and updated the blog post here :

It should give you all the information for the howto use that feature.

I have released as well a minor update in 1.5.1 to allow you to define the environment variable RACKSPACE_SERVICENET to force the use of the Rackspace ServiceNET this allow you to don’t have to modify the tools and have a clean code between prod and testing.

How to connect to Rackspace Cloud Files via ServiceNET

If you are a Rackspace customer and you are are planning to use Rackspace Cloud Files via it’s internal network (ServiceNet) so you don’t get billed for the bandwidth going over Cloud Files this is how you can do.

The first thing is to make sure with your support team if your servers are connected to ServiceNet and if you have that connection then there is a small change to do in your code.

The second thing is to use the just released 1.5.0 version on GitHUB for PHP :

and for python :

(you need to click on the download link at the top to download the tarball of the release).

Afer this is just a matter to set the argument servicenet=True, for example in PHP :


$auth = new CF_Authentication($user, $api_key);
$conn = new CF_Connection($auth, $servicenet=true);

In Python you can do like this :


cnx = cloudfiles.get_connection(username, api_key, servicenet=True)
