finally i got openSSH/OpenSftp in conjunction with ubuntu and with filezilla or swish on Windows to work over Wifi:
OpenSSH on touchpad
see also this here:
Now i have the Prob, that after using this for one or two times, i couldnt get connection again. I searched everywhere in this forum and tried things proposed in the wikis, cant find a solution.
After new installation of openSSH and openSftp, connection is back for some times and disappears again.
Is there anybody out there with the same or similar Prob and perhaps a solution or a workaround.
I find it very conveiniend, not have to use the usb-Cable, where my Pixi is disconnected from networks an be able to transfer files and data OTA .
Maybe it is a prob solely for Pixi, but i cant believe this.
Any help is appreciated
