if you gave me step by step instructions
Of course, Paola.
1).follow komar's instruction on how to get keys on your device:[If you don't have "poterm", connect the reader up via USB and create
a file called "create-keys" in the "pb_sshd" directory. It doesn't
matter what it contains. The next time "sshd_start.app" is run, it
will automatically run the "pb_sshd/make-keys.sh" script (and then
delete the "create-keys" file). Then you can move the "id_rsa" and
"id_rsa.pub" files from "pb_sshd" to your computer.]
2).open your Filezilla, then in the 'settings', select 'connection' and then 'sftp'. On the selected page, you can add "id_rsa" to filezilla.
3).open the 'site manager' of filezilla, create a new site. there you type host and port, choose sftp as the protocol, select normal as logon type and the user name is 'reader'.
4). run "sshd_start" on your device and then click 'connect' of filezilla.
As a matter of fact, once you add the private key to filezilla, the rest is not very different from connecting a ftp site.
I wish I could upload a picture, so I don't need to explain anything at all.
