SMSCON

Revision as of 09:07, 9 September 2010

DESCRIPTION

SMSCON is a n900 complete control utility by sending sms messages to it. This is handy in case you can't find your phone (it's lost or stolen).

SMSCON is a two part Python script running in CLI; smscon & smscon_daemon. SMSCON is the CLI control part and smscon_daemon is the "running in the background" part. The configuration file for all the user settings is smscon_config.

WHAT CAN IT DO

SMSCON can:

   * autoload at boot (when set);
     when device reboots it loads smscon_daemon in the background.
   * creates a log file (on the device)
   * detect SIM card change and sends new phonenumber and IMSI code (returns SMS) to other known mobile number;
     if somebody has stolen your phone and put his/hers own SIM card in it.
   * send current GPS location coordinates (returns SMS).
   * reboot the phone;
     only works if your SIM card hasn't a lock code.
   * shutdown the phone.
   * open a reverse ssh connection to your own server (GPRS connection);
     control the device at CLI level from your own home.
   * email a frontcam picture to your email address (GPRS connection); to see where your phone is or who is using it.
   * send the current remaining battery charge (returns SMS).
   * make the phone call you;
     you can listen where your phone is (returns phonecall)

INSTALLATION

SMSCON needs the following packages installed on your device to install and run:

apt-get install maemo-python-device-env (the Python language package)
apt-get install python-location
apt-get install pexpect
apt-get install gstreamer-tools
apt-get install openssh

The three files (smscon, smscon_daemon & smscon_config) are placed in the /usr/bin directory.

Also you need a fixed IP address on your remote server for the reverse-ssh (port 22) connection, if you want to use the 'Remoteon' / 'Remoteoff' command.

USAGE

SMSCON is triggered by a SMS message with a predefined known command and then will execute the task in the background. If so it will send a reply SMS with the information.

The default commands are:

Nokia-N900:~# smscon -sms
Check
Reboot
Poweroff
Power
Location
Remoteon
Remoteoff
Camera
Call

These commands can be altered in smscon_config file.

Options for smscon are:

Nokia-N900:~# smscon
== smscon v0.3.0 - Nokia N900 remote control utility ==
 Options:
  -init    : create smscon_config
  -start   : start smscon_daemon
  -stop    : stop smscon_daemon
  -status  : get smscon_daemon status
  -log     : show the log file
  -clear   : erase the log file
  -sms     : show sms commands
  -help    : this help menu
 Special options:
  -boot    : start smscon_daemon at device boot
  -unboot  : remove start of smscon_daemon at device boot
  -reset   : factory default
  -imsi    : show imsi code file
  -delete  : delete imsi code file

SMSCON is intended for people who have Python programming / Linux experience so you can adjust the script to your own needs.

REMOTE SSH CONNECTION

When the (reverse-)SSH connection is made (default command 'Remoteon') you can from the server side (your own server) connect to your Nokia device with the following command:

ssh -p 8080 localhost -l root

FIRST TIME USAGE

The first time start SMSCON with the following command (smscon -init); it creates a new config file (usr/bin/smscon_config) which you must edit to your own needs (change all "xxxxxxx"'s). I use Putty / WinSCP on Windows for this. Don't use a Windows editor! The second time you start smscon (smscon -start) it loads the configured user settings file and is now active. It then stores your valid IMSI code in a file (smscon_code) if the file doesn't exists. When later a new SIM card is inserted the new IMSI code is verified with the code in the stored file. This is the "SIM card change detect".

Nokia-N900:~# smscon -init
creating new user config file in "/usr/bin/smscon_config".
WARNING: first edit smscon_config before using smscon!

Nokia-N900:~# smscon -start
smscon_daemon started.

Nokia-N900~# smscon -log
(Thu Sep  2 22:10:24 2010) SMSCON: smscon_daemon active
(Thu Sep  2 22:10:25 2010) DAEMON: user settings succesfully loaded from "smscon_config" file
(Thu Sep  2 22:10:25 2010) DAEMON INIT: initalizing new IMSI file with current valid IMSI code
(Thu Sep  2 22:10:25 2010) DAEMON: current valid IMSI code (XXXXXXXXXXXXXXX) saved to file
(Thu Sep  2 22:10:25 2010) DAEMON: authorized IMSI code found
(Thu Sep  2 22:10:25 2010) DAEMON WARNING: smscon doesn't autoload at boot
(Thu Sep  2 22:10:25 2010) DAEMON: no test arguments passed for daemon

TESTERS NEEDED

I like to hear if it works for you. I only could test it with two Vodafone SIM cards from The Netherlands, I want to know if it also works with other cards & networks in other countries...

CURRENT VERSION: v0.3.0

   * bug fixes, bug fixes, bug fixes in data connection handling (I hope, you test it)
   * at the moment smscon can only connect to a smtp server (for sending the email) without secure authentication. (will be solved in the future I hope).

CHANGES FROM v0.2.4

   * now email sending & ssh connection -only works- through GPRS connection because GPRS is always available. (a random WLAN access only works if preconfigured)
   * when you install smscon package there is no more 'smscon_config' template file installed; the first time you start smscon,
     it creates a new config file at /usr/bin/smscon_config which you must edit. The next time you start smscon is loads
     this edited config file and is then active. (see also FIRST TIME USAGE)
   * when installing future updates of smscon settings file is not deleted.
   * command smscon -reset resets your complete configuration to the state after your smscon package installation.
     (deleting boot, config, code & log file)
   * smscon_daemon will stop if no SIM card is found. (smscon has no use then)
   * For smscon to work properly set in Nokia menu Settings --> Internet connection to 'Any connection'.

FUTURE DEVELOPMENT

   * smscon will be set to load at boot at installation of smscon;
     this can later be undone with the -unboot option if needed.
   * new commands: "Trackon" / "Trackoff"; smscon will continually send (after x time) a sms with current gps coordinates.
   * smscon will lock the device after first valid sms command is received (user configurable).
   * rewriting connection handeling by smscon.
   * storing all smscon_config user variables in gconf database.
   * saving the phone number where you send your sms messages
     from in smscon_config (in VALIDSENDERNUMBER). At the
     moment it is lost after reboot and uses the initial number stored
     in VALIDSENDERNUMBER.

DISCLAMER:

If this software does harmfull/unwanted things (not to be expected) to your device in any way the developers can't be responsible for this.
