Sshfs

I used to work with Quanta on my Ubuntu machine, but Intrepid does not have kio slaves so for sftp which is necessary, it did not work anymore. After doing some reading I still use Quanta but I use it in combination with Sshfs:

SSH is a secure protocol for communicating between machines. Sshfs is a tool that uses ssh to enable mounting of a remote filesystem on a local machine; the network is (mostly) transparent to the user. Because ssh authenticates connections, you can be sure that only those who should have access to remote directories can mount them (as long as everything is configured properly). Because ssh encrypts connections, no one can see your files as they are transferred over the network.

And SshfsGUI. More information can be found:
