Although it is possible to connect to CCB servers using the simple terminal application (Applications/Utilities/Terminal) we recommend using the xterm via XQuartz for all connections. This will allow you to gain maximum use of the software available via your CCB account.

  • Start XQuartz (from "Applications" and then "Utilities")
  • Within XQuartz, open a new xterm window by choosing "Applications" and then "Terminal".
  • To connect to CCB type the following and press the return key:
    (Note: in the example below, the -Y is upper-case, and the -l is a lower-case 'L' )
    ssh -Y -l username
