Thank you all for your input..
but it seem my question is still not fully answered...
let me rephrase, I'm not looking to have a GUI to transfer files, but I would like to execute terminal command remotely (from my computer) to my android phone. Like SSH .
So I've read that I can install a SSH server on my android phone.. (If you know some's (FLOSS), I'm all ears)
Or if you know a better way than SSH I'm all ears too.
