    Audio monitoring - access remote machine's mic via SSH

    Hi guys. I just learnt a clever little trick *use with caution and respect the privacy of others - using this technique for the wrong reasons, <<could>> see you in legal troubles!*:

    Basically, you are able to open the microphone of a remote GNU/Linux machine, so long as you have the SSH password for that machine, and so long as the remote machine has SSH server installed & running.

    Here is how I got it to work:

    Assume the following; 192.168.1.1 is LOCAL, 192.168.1.2 is REMOTE.

    1/ I installed openssh-server & openssh-client on BOTH test machines:

    Code:
    sudo aptitude install openssh-server openssh-client
    2/ On the LOCAL (my) machine, I opened terminal and entered:

    Code:
    ssh <username>@192.168.1.2 'dd bs=1k if=/dev/audio' > /dev/audio
    Basically, you are concatenating the audio input device (REMOTE) to the audio output device (LOCAL) with a stream block size of 1Kb.

    Your sound card may be /dev/audio1 as mine is (it is a USB sound card) so I shall assume you know it is /dev/<yourSoundCardNode>


    3/ You *should* now hear every single sound from the microphone on the REMOTE machine!


    use responsibly, and have a lot of fun.

    Is this only if there's no password auth or passkey auth enabled or does it work regardless of these security measures?

    I can only assume one would need FULL root permissions for the remote machine - I am not enough of a guru to say for sure, though. I used two default Karmic installs, of which I am admin to both.

    It's just for *fun* dude, it is not supposed to be breaking into someone's machine LOL.

    PS: Picking the lock on an open door would be no less hard; I simply PUSHED the open door!
