If you are using windows and accessing linux servers through ssh, you may use ssh secure shell client, where it bundle with ssh secure shell file transfer client. The file transfer client allows you can do a file transfer drag and drop. Well in linux you can do the samething like that if you have konqueror installed.
Konqueror is almost everything in KDE, it is a file browser as well as an internet browser. It also allows you to access the application menu, settings menu and other menus. It is a container for kde apps, which it allows apps like kate, kpdf embeded into konqueror. Needless to say you can access to samba drives and ftp server, but now I would like to show you how to perform ssh file transfer with just drag and drop in konqueror.
You can either use sftp or fish, both works just nice in konqueror. Assume server ip 192.168.1.1 with default ssh port and username visitor, you can initiate fish in konqueror like this.
Type the line below to the location bar.
Konqueror will prompts you a dialog for you to enter your password, and it will leads you to the home directory. Now you can transfer files and folders by drag and drop.
You may want to split the konqueror window into two and so that is convenient for you to drag and drop. Press Ctrl+Shift+T will split the view of current window, and then you can change directory of the second view to the destination folder and start to transfer files.
In case you having a different ssh port, you do this:
The same way you can do with sftp in konqueror:
Well, if you are confortable with command lines, you can do sftp through command line. But I would like to suggest you to try scp, I find scp is more flexible for me if I know the exact location of my source and destination.
