Log into the User Interface

ALERT! If you are using a Windows based Operating system you will need an ssh client in order to continue. We recommend you download and install on your local machine putty (for unix shell access) and winscp (for file transfers). For more information on configuration and connection details please take some time to view the screencast below.

ALERT! If you are using Linux or MAC OS X from the command line/terminal issue the following command


where username should be replaced with your own username.

Log into the User Interface with X-forwarding

To log in the User Interface with X window forwarding enabled please follow the guidelines below:

  • For Windows users we recommend using the Xming server to enable X forwarding over ssh
  • For Linux users: Use the following command in a terminal window
       ssh -X
    where username should be replaced with your own username.
  • For MAC OS X users: First make sure the X Window server is running on your local machine. This is usually located under Applications/Utilities/X11. Then use the following command in a terminal window
       ssh -XY
    where username should be replaced with your own username.

Transfer files to or from the User Interface

To transfer files from your local computer to the User Interface and vice versa you will need to use either scp or sftp protocols. Depending on the Operating System of your local computer the following options are recommended:

  • For Windows users we recommend using the winscp utility. To download and execute the application watch the following screecast at 6:00 and for usage details refer to the same screencast at 6:40.
  • For Linux and MAC OS X users: Use the scp and/or sftp commands from the command line (terminal)

Tip: For Windows and MAC OS X users we also recommend the Cyberduck client smile .
