Hi ,
 
             Thank you very much  for the response  but still i am getting same error can you please suggest accordingly  .I had done 3 different tries in my user file those tries and output is given below
 
Also  i more think i remember while my installation db.ippool file and db.index file where not formed then i had to created those files in respective directory and i had given appropriate permission for that
 
whether it will create any problem ?.... Also   while useing  command rlm_ippool_tool -a ip-pool.db ip-index.db i am getting output as 0 whether is it any problem ?...
