You can check if an ECFLOW server is running on a system using the ping command, e.g.

• 1. Check if server is running on 'localhost' on port 3141*
     ecflow_client --ping
  2. Check if server running on machine 'fred'*
     ecflow_client –-ping -–host=fred
  3. Check if server running on 'fred' with port 3222*
     ecflow_client –-ping –-host=fred –-port=3222
  4. Check if server running using ECF_PORT and ECF_NODE*
     export ECF_PORT=3144
     export ECF_NODE=fred
     ecflow_client --ping
     Note: when ECF_NODE and ECF_PORT are used in conjunction with command line arguments, then the command line argument take precedence.
