    A technical clarification: The terrestrial segment of GPS is receive

    based data service.
    Yes GPRS is the standard way common people have access to the cell based GPRS however, as in the marine system, 98% of devices are GPS receive only but there are GPS send/receive devices that do not have any cell communication capability. These devices work way out on the oceans via GPS uplink (there are no cell towers out away from shore).

    In GPRS, a local cell tower receives a GPRS signal from cell technology devices and relays those requests a GPS uplink station which in turn returns the GPS downlink data.

    I do recall there was a time not so many years ago when I was terrified
    to go into YaST > System > /etc/sysconfig Editor, and I would not
    naturally look there for a place to tune an application. So we probably
    need to put this pointer (to do the tuning in YaST) on
    "-threatingbehaviour's future Prey how-to-".

    I'm pondering if I should use the Prey web site. I note it is possibly
    open to abuse by the Prey webmaster (if they were so inclined to spy)
    and so I may just set up the alternate method site instead.

    Hi
    OK, I found the proper prey configurator and have updated the build as
    using sysconfig didn't seem to save the changes for me. So if you have
    installed it please update and run the menu item to add your key/api
    again.

    No. There are no GPS send devices. The number of codes in the code
    space used for GPS can only support a handful of stations beyond a full
    constellation in the space segment. The GPS devices that you can buy are
    receive only.
    There are satellite cell phone systems/services (Iridium) that can
    provide the reporting function over 90% of the globe.

    Wrong again. Cell towers including GPRS, UMTS, HSPDA all talk to the
    normal fiber optic infrastructure, though sometimes through a terrestrial
    only microwave link.
    If anybody tried transmitting to the GPS satellites they would quickly
    find themselves in jail. The US Military owns the satellites. They just
    let civilians use the signals they transmit for similar positioning
    purposes.

    Do notice the persistent use of receiver in the Wikipedia article:

    http://en.wikipedia.org/wiki/GPS

    And most important do remember to disrespect and distrust marketing hype.

    I finally got around to installing this in openSUSE-11.3 (on my Dell Studio 1537 laptop - I want it functional for my vacation - I leave tomorrow for 3 weeks) ... and I'm currently testing it to see if it works (on 11.3 on this laptop).

    Cool, a success story. I like hearing success stories.

    alright I just got a new laptop about 2 days ago got my system all configured the way I like it and finally downloaded prey..I have edited the config file with my api and device key and when I run the prey.sh shell I get the following message
    -- Looking for connection...
    -- Got network connection!
    -- Checking URL...

    >> Verifying status...

    -- Got status code 400!
    -- Nothing to worry about.

    -- Cleaning up!
    now what exactly is that supposed to mean? my device is still unverified and I'm completely lost at this point..the readme is pretty much worthless on the subject..can anyone please help me on getting this up and running? Thanks

    Hi
    You just need to run prey.sh as root user, this will create the crontab
    entry (check with the command crontab -l). I still have an open query on
    the configuration GUI, this can be run as your user.

    I've been doing some minor edits, so just confirm you have the latest
    which is prey-0.4.3-11.1

    In my case on openSUSE-11.3 (64-bit) with KDE-4.4.4 to install prey I needed to use "kdesu prey" , although it is possible that "su - " followed by "prey" would have worked (I did not try that).
