If you are only using command line systems, you have to use the keyboard as part of copying file method.
But there is actually, sort of an easier method. You will need to have the following installed on the systems: openssh-server, fuser, and sshfs for starters.
The easiest way to set up a share is to go to the browser and use the sftp protocol (vs ftp or http) to point to the share. Notice there are not shares set up yet. and again the file we want to copy is servers.txt.
Now you should see the share in the lower left hand side window.
Now you want to drag and drop the file.
