At home I have a PC and a notebook. Both are connected at the same time to my internet provider (dynamic IP for both) trough a switch. I need to transfer data from the notebook to the PC. May be ssh is an option? Whatshould I do in order the devices see one to the other?
If you have KDE you can use Konqueror and type the following URL - fish://IP-ADDRESS/
This is a GUI way of file transfer It uses SSHD to be enabled.
