NAME
       epmd - Erlang Port Mapper Daemon

DESCRIPTION
       This  daemon acts as a name server on all hosts involved in distributed
       Erlang computations. When an Erlang node starts, the node  has  a  name
       and  it  obtains  an  address from the host OS kernel. The name and the
       address are sent to the epmd daemon running on the  local  host.  In  a
       TCP/IP  environment,  the address consists of the IP address and a port
       number. The name of the node is an atom on the form of  Name@Node.  The
       job  of  the epmd daemon is to keep track of which node name listens on
       which  address.  Hence,  epmd  map  symbolic  node  names  to   machine
       addresses.

       The daemon is started automatically by the Erlang start-up script.

       The  program epmd can also be used for a variety of other purposes, for
       example checking the DNS (Domain Name System) configuration of a  host.
