Oh man, this is SOOOOOO Cool!! I got sshfs wifi to work on my K4 so I can mount it on my desktop like a regular drive with the whole filesystem visible.
Here's how I did it:
The first step is to get ssh wifi working. Once you have that you can work on the filesystem in a terminal without using the USB cable.
Get the file at
https://www.mobileread.com/forums/att...4&d=1285246572 and extract it somewhere.
Log into the Kindle as root. Do 'mntroot rw'.
Do 'mkdir /usr/libexec'. Copy the file you grabbed and extracted above to this new directory.
Log out and in a terminal 'sftp
root@xxx.xxx.xxx.xxx'. Replace the x's with the Kindle's IP on your local network. Once you give it the password you should get the sftp> prompt. So far, so good. Now log out.
On your local machine create a directory to which you have permissions. I used ~/kindle.
Now try 'sshfs
root@xxx.xxx.xxx.xxx:/ ~/kindle' from your terminal. This should mount the Kindle filesystem at ~/kindle and may even put an icon on your desktop. Mine does. (In the screenshot I mounted /mnt)
To unmount the Kindle you have to issue 'fusermount -u /your/mount/point'. On my system, if the Kindle has timed out (another problem that needs addressing), this may not work and it freezes the Desktop.
Another mod I did was to create a /root directory on / in the Kindle. I opened the /etc/passwd file and changed the root target to /root instead of /tmp/root. Then I created /root/.ssh/authorized_keys and set up public and private keys on host and client. I don't know if this is really necessary since I always get prompted for a password anyway. BTW, I changed root's password to something I could remember!
