SMSCON

SMSCON provides complete control of your N900 by sending SMS messages to it. This is particularly handy in case you cannot find your phone, for example if it has been lost or stolen. SMSCON is a two part Python script running in CLI;  and. is the CLI control part and  is the "running in the background" part. The configuration file for all the user settings is in the  file. =Functionality=

SMSCON can:


 * autoload at boot (this is default set at install of smscon package); when device reboots it loads  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 or EMAIL with GoogleMaps picture with location on it).
 * 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)
 * lock the device; nobody can control your device anymore.

=Installation=

SMSCON is writen in Python and needs the following packages installed on your device to install and run:

apt-get install maemo-python-device-env apt-get install python-location apt-get install pexpect apt-get install gstreamer-tools apt-get install openssh

The two ( and  ) are placed in the   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' function. =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.

Commands
The default commands are: Nokia-N900:~# smscon -sms COM_CHECK = 'Check' COM_REBOOT = 'Reboot' COM_POWEROFF = 'Poweroff' COM_POWER = 'Power' COM_LOCATION = 'Location' COM_REMOTEON = 'Remoteon' COM_REMOTEOFF = 'Remoteoff' COM_CAMERA = 'Camera' COM_CALL = 'Call' COM_LOCK = 'Lock' COM_UNLOCK = 'Unlock' COM_TRACKON = 'Trackon' COM_TRACKOFF = 'Trackoff'

These commands can be altered in the  file:


 * 1) smscon user settings (v0.4.0)

 * 1) Email settings
 * 2) (only works for smtp access without secure authentication!)

REMOTEHOST       = 'XXXXXXXXXXX.XX' REMOTEPORT       = 22 REMOTEUSER       = 'XXXXXXXXXXXXX' REMOTEPASSWORD   = 'XXXXXXXXXX'
 * 1) Reverse-ssh settings

COMMANDREPLY     = 'no'
 * 1) Send acknowledge sms
 * 2) (send acknowledge sms after receiving valid sms command: 'yes' / 'no')

AUTODEVICELOCK   = 'no'
 * 1) Device lock
 * 2) (lock device after receiving valid sms command: 'yes' / 'no')

GPSTIMEOUT       = 600 GPSPOLLING       = 4 GPSINTERVAL      = 60 GPSSEND          = 'email'
 * 1) Gps setings
 * 2) (if no gps coordinates acquired after 600 seconds then stop)
 * 1) (number of gps coordinates to acquire and use the most accurate in "Location" mode)
 * 1) (time between sending coordinate sms in 'Trackon' mode: 10 / 20 / 30 / 60 / 120)
 * 1) (method to send gps coordinates: 'email' / 'sms')

Options
The available options for SMSCON are: Nokia-N900:~# smscon

smscon v0.4.0 - Nokia N900 remote control utility
Options: -start     : start smscon_daemon -stop      : stop smscon_daemon -status    : get smscon_daemon status -log       : show log file -del log   : erase 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 -del imsi  : delete smscon_code file -init      : create default smscon_config -del config : delete smscon_config file

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

After installation
After installation  will generate a new configuration file  which you *must* edit to your own needs (change all "xxxxxxx"'s). Warning: Use Putty / WinSCP on Windows for this. Don't use a Windows editor, this may break the config file! SMSCON will also be installed to autoload at boot, this can be disabled with the command " " and re-enabled by " ".

The first time you start SMSCON it loads the configured user settings file and is now active. then stores your valid IMSI code in a file if the file doesn't exist. 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 -start smscon_daemon started.

All user action and behavior of  will be logged in the log file:

Nokia-N900:~# smscon -log SMSCON INFO: smscon_daemon active (09-09-2010 11:00:48) DAEMON INFO: user settings succesfully loaded from "smscon_config" file (09-09-2010 11:00:49) DAEMON INFO: reading valid IMSI code (XXXXXXXXXXXXXXX) from file (09-09-2010 11:00:49) DAEMON INFO: authorized IMSI code found (09-09-2010 11:00:49) DAEMON INFO: smscon autoloads at boot (09-09-2010 11:00:49)

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

ssh -p 8080 localhost -l root =Current version v0.4.0=


 * bug fixes, bug fixes, bug fixes in data connection handling (I hope, you test it).
 * sms commands have changed; you can now use spaces in commands.
 * will use only GPRS connection for sending email and reverse-ssh connection.
 * will lock the device after first valid sms command is received (user configurable).
 * now stores the phonenumber where you send your control sms's from into.
 * added new control command "Lock" and "Unlock"; you now can lock and unlock your device so nobody can use your device.
 * added new control command "Trackon" and "Trackoff"; continiously send (after  time) sms's (with current location) or email messages (HTML email with current location as a GoogleMaps picture!).
 * at the moment SMSCON can only connect to a smtp server (for sending email) without secure authentication. (will be solved in the future I hope).
 * email sending and ssh connection -only works- through GPRS connection.
 * when installing future updates of SMSCON user settings file is not deleted or overwritten.
 * command smscon -reset resets your complete configuration to the state after your smscon package installation. (deleting boot, config, code and log file)
 * will stop if no SIM card is found at boot. No SMS sending/receiving capability --> no control.
 * changed the way the log file is shown.

=Future development=


 * saving all  user variables in gconf database. No need for   file anymore.
 * only send camera picture (command "Camera") when keyboard slider is opened.

=Testers needed= Please test this software, I like to hear if it works for you or not. I only could test it with two Vodafone SIM cards from The Netherlands, I want to know if it also works with other cards and networks in other countries...

=Disclaimer=

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