The CRT server, np04-crt-001.cern.ch, is a physical computer that can be found in the CRT rack in EHN1. It is the only DAQ computer configured to run the CRT backend (so far), so it runs the CRT board readers. It is also used for developing the CRT DAQ and the calibration workflow.

Logging in to the CRT Server

  1. Get a kerberos ticket for someone who can log in as np04daq. Shifters should probably be able to do this. If step 2 doesn't work and complains about permissions, contact the CrtExperts or a DAQ expert for help logging in.
  2. You need to do the next steps from the CERN network. If you're trying to do this from offsite, use your CERN computing account to login to lxplus.cern.ch.
  3. Log in to the CRT server as np04daq:

    ssh np04daq@np04-crt-001NOSPAMPLEASE.cern.ch

    If the connection seems to hang for a few minutes, the CRT server might be down. Contact the CrtExperts.

  4. source /nfs/sw/crt/readout_linux/script/setup.sh #Add the CRT perl and expect scripts to PATH.
    #This doesn't seem to be mutually exclusive with setting up the CRT timing endpoint's command line interface
