    Shutdown and tansfer to ILT

    Log into the interface computer (lofarx)

     

    ssh -X observer@lofarx

     

    Set up SSH stuff with the following commands

     

    ssh-agent /bin/tcsh -l

    ssh-add


    You will need the password for the observer account.

    Log into the DE601 LCU

     

    ssh -X de601c

     

    Check that no-one else is on the station

     

    w

     

    If there is more than one login active (you), then check who else is logged into the station. 

    If another "user9" is logged in then contact the observers and tell them to log out.

    Check software level (should be 0)

    Kill all existing beams:

    killpointing

     

    swlevel

    If not in software level 0, bring it down:

    swlevel 0

     

    Verify that no station processes are running.  A report of swlevel 0 from the swlevel program does not necessarity mean that everything is stopped.

    ps -AF

    If there are more "user9" processes running than your own, please ask the observers to stop them or kill them yourself.

    Hand the station back to ILT

    Send an e-mail to "lofar-ops@astron.nl" and "observer@astron.nl" (with CC to "lofar-ops@mpifr-bonn.mpg.de") telling that we are done and that the station can be switched to ILT mode.

    One wat to do this is to run the attached "mail_ILTOPS_EF_shutdown.sh" script on your local desktop.
