[McMCrypto]

Hi, guys,  i am running  one private ETH poolserver,  but i want  run another ETC poolserver in the same machine,

obviously i must run another  instance  and point the ETC poolserver to another ports (RPC,API),  could you send some tips  about the  geth  commandline  for running the 2nd poolserver   ?  (ETC in my case will be the second) , thanks!
