Getting the Most Out of SSH

But you might not know that this tool does a lot more than offer you a secured command line. Here are some tips and tricks that'll help you do everything from detect man-in-the-middle attacks (how are you supposed to know if you should accept a new hosts public key, anyway?) to evading restrictions on Web surfing." What are your own favorite tricks for using SSH?

    What about unlimited encrypted storage?

    you need TCP forwarding enabled in your sshd_config, then

    ssh -L localhost:2222:localhost:2222 localhost
    $ echo "data you wanna save" | nc localhost 2222

    # or if you want to backup your hdd, try:
    $ cat /dev/sda1 | nc localhost 2222

    # the data will be forwarded forever in the loopback link at no cost until you read it back:
    $ nc localhost 2222 > hdd-backup.bin

    # profit!
