This will open a secure session to the server in question and allow you to browse directories and download files. It also understands smb:// for samba shares. Even cooler, you can have multiple systems up as separate panes of the same window and copy a file from remote system A to remote system B. Awesome.
Yeah, I like Dolphin also. It doesn’t actually need KDE to be running as window manager; probably does need KDE services but runs fine with other managers such as Xfce.
