dd over netcat, no ssh

Copying from source to target where target has sshd running:

    dd if=/dev/sda | gzip | ssh root@target 'gzip -d | dd of=/dev/sda'

Copying from source to target via sshd_host when target is not running sshd.

    Target: nc -l -p 62222 | dd of=/dev/sda bs=$((16 * 1024 * 1024))
    Source: ssh -L 62222:target:62222 sshd_host &

    Source: dd if=/dev/sda | nc -w 3 localhost 62222

    dd - if= is the source, of= is the destination, bs= is the block size. Different block sizes may improve performance. 16 is usuually a fairly reasonable starting point. You can also use count= to indicate how many blocks to copy.

    nc - -p indicates the port to use for services. -l is used to start a service. -w sets up the time to wait for data in the pipline before quiting.

    ssh - -L sets up the tunnel on the remote host. The format of the argument is, local_port:target_host:target_port. Your local program (nc) connects to the local_port, this connection is tunneled and connected to target_port on the target_host.
