Remote Connection to the Mainframe

Using the Web Browser
  • Open the web browser and type the 'Device Name' of the mainframe (given in registeration process) in the address bar.
  • Enter the user credentials.
Using the Terminal
  • Type ssh <userName>@<deviceName> if the mainframe is CAEN SY4527.
  • Or type telnet <deviceName > 1527 if the mainframe is CAEN SY1527.

Web Browser cannot be used from outside CERN to connect to a mainframe remotel.

Using the Terminal
  • Open a terminal window and log into personal lxplus account by typing ssh -Y userName@lxplus6.cern.ch.
  • Then log into cmsusr.cern.ch by typing ssh -Y cmsusr.cern.ch.
  • Enter the user credentials (not possible if the user does not have an account in cmsusr.cern.ch).
  • Log into the mainframe using ssh admin@mainframeIPaddress command.
  • Provide the mainframe password.

The resultant display would be similar to the image below, where 'Ch#' column presents the board number and the corresponding channel number in . format.
