On the Hummy, dropbear passwords are kept in /mod/etc/dropbear/shadow. To change the password, this file will have to be edited directly.
Assuming you are running a custom firmware and have installed the file editor package ‘nano’ from the web interface, do the following:
On a linux box generate the new password:
echo 'example_pasword' | makepasswd --crypt --clearfrom=-
where ‘oQfckhu/L3XBU’ is going to be your new password hash. Of course, you will want to change ‘example_pasword’ to something else.
Connect to your hummy box using telnet and then
cp /mod/etc/dropbear/shadow /mod/etc/dropbear/shadow.ori nano /mod/etc/dropbear/shadow
and change the line below (or whatever is in your original password file)
where the new hashed password between the first two colons is copied from the output of makepasswd.
If makepasswd is not available on your linux machine, it can be installed by
sudo apt-get install makepasswd
Once finished, you can easily move files between two hummy boxes, for example:
On your linux box type
and after having logged in to pvr1
cd /mnt/hd2/My\ Video rsync -av --progress "root@pvr2:/mnt/hd2/My\ Video/The\ Tree\ of\ Life_20141223_0256.*" ./
Note that you both have to quote the path string and escape the spaces in it.
