How To Connect

On this page, we explain how to connect to Satellite CCRMA over the Ethernet cable.

Mac OS X

If you are using Mac OS 10.8 (Mountain Lion) you need to install XQuartz so that XWindows will work. Prior versions (10.5+) have XWindows installed by default.

Go to System Preferences, select Network, and choose the Ethernet module. Write down your current settings in case you think that you might need them in the future. (For example, if you use Ethernet to connect to the Internet in your dormitory, you probably want to save these settings for when you go home.) Now change your Ethernet settings to the following:

Configure: Manually

IP Address:

Subnet Mask:

The remaining items such as Router, DNS Server, and Search Domains can be left blank for now, and click the Apply button in the bottom right to apply the settings.

If your laptop is currently connected to the Internet using some method other than Ethernet: It can be convenient to enable the Beagleboard to get onto the Internet. Internet Sharing will not work on Mac OS X 10.7 (Lion) or Mac OS X 10.8 (Mountain Lion), so skip this step on those systems. Go back to System Preferences and choose Sharing. Edit the settings so that your Internet connection is shared with the Ethernet port. In order to do this, you may have to disable Internet Sharing temporarily. Finally, click the Internet Sharing checkbox to enable this option.

You will use the Terminal program to login to Satellite CCRMA over the Ethernet connection.

You will also need a program called X11. Check if this program is already installed. In most recent version of OS X, X11 is installed by default in either the Applications folder or the Utilities folder, but in older versions it was necessary to install it from the Developer Tools CD. No matter what, if you cannot find the X11 program on your Mac, download it from here.

Now open up a window in Terminal. Your Satellite CCRMA kit should choose the IP address To check that it is visible type the command ping, and see how fast the network response is. Once you are satisfied, hit Control-C to quit ping. Then, to finally login to Satellite CCRMA, type

ssh -XY ccrma@

The password should be temppwd.

Windows 7

  • First, connect Satellite CCRMA to your laptop via the Ethernet connector. If you don't have one, ask us for a USB to Ethernet adaptor.
  • Ideally, your laptop should be connected to the Internet through a different connection other than Ethernet. Since it will be good to have your Satellite CCRMA to have access to the Internet, the idea is to share your current Internet connection, which will probably be a wireless network connection. To do so, go again to Control Panel\Network and Internet\Network Connections, right-click on Wireless Network Connection and click Properties. Switch to the Sharing tab, and check the box saying Allow other network users to connect through this computer's Internet connection. Then, in Home networking connection select Local Area Connection'.' (Note: Depending on your version of Windows, you may have to do something slightly different. Don't worry if you don't figure it out -- we can help out in lab. Also, if you are using Windows 7 Starter Edition, it will not be possible to share your Internet connection.)
  • Then you will need to get X Windows to login to Satellite CCRMA through the Ethernet connection.:
    • If you are not already using Cygwin, we recommend downloading and installing Putty and XMING (to do the X11 forwarding). This is significantly faster to install than Cygwin. More instructions on how to use X11 with Putty are here.
    • If you prefer to use Cygwin instead, which takes much longer to install, then follow these instructions instead: X Windows is included in the current Cygwin/X distribution. (Cygwin/X installer can be downloaded from [1].) Choose only the required packages from Cygwin are openssh and xinit.
  • Go to Control Panel\Network and Internet\Network Connections (or Control Panel\Network and Sharing Center), right-click on Local Area Network (or Local Area Connection) and go to Properties. Select Internet Protocol Version 4, and click on Properties. There, manually configure:
    IP Address:
    Subnet Mask:
    Leave the remaining items as they are.
  • Now open the XWin Server application. Run the command
    export DISPLAY=:0.0
    Your Satellite CCRMA kit should choose the IP address To login to Satellite CCRMA, type
    "ssh -XY ccrma@"
    The password should be temppwd.


Instructions for Ubuntu 10.04 Netbook Remix:

Run ifconfig in a terminal and look for your wired ethernet device. It will probably be called "eth0". Copy down the value next to HWaddr.

Go to "System" -> "Network Connections".

Under the "Wired" tab of the dialog that opens click "Add".

Set the "Connection name" to something logical, like CCRMA Satellite. Paste the value you copied from HWAddress in the "MAC address" box.

Click the "IPv4 Settings" tab. Change "Method" to "Manual". Next to "Addresses" click "Add". In the "Address" column type "". In the "Netmask" column type "". Click "Apply".

In the notification area on your desktop panel, click the NetworkManager Applet icon. Select the connection you just created. You now should be able to ssh into the board by typing ssh -XY ccrma@ in a terminal.
