Jean, As user ldm, on wx.mts.sdapcd.org, enter the command: ldmadmin watch If your LDM is running, a list of data products will scroll by. or you can do a "top" to see the processes, or ps -ef | grep ldm The processes will show up as rpc.ldmd, these running indicate a running LDM... If you desire, I can login as ldm and take a peek if you provide the ldm pwd..
