Today I discovered a great possibility for accessing a remote filesystem via ssh using dolphin.

Dolphin uses the KIO tool which provides several great features / protocols (e.g. direct encoding of a CD as MP3 ). Another cool feature is the fish-protocol which allows to access a ssh-directory directly.

How to use?
If fish-protocol is installed, just type fish://User@server and viola access, after typing in your password, is estabilshed.
