Ssh using nautilus (or) Cannot use gedit on multiple remote machines using ssh

Open a nautilus file browser window and select "connect to server" from the menu in the top panel.

Enter in the server info (use ssh:// or sftp:// for ssh connections).

For Ex:

ssh://username@remotemachine.com

Click on connect.

Once connected you can bookmark the location using ctrl+d. Then double click the file you want to edit in gedit.

One drawback: unless you ssh in as root, opening files that require root privileges is less straight forward using this approach. One thing you can do, if you have nautilus-open-terminal installed, is to right click in the nautilus window where the file is located and select "open in remote terminal", then use sudo nano filename.txt as above.
