     NAME
          udpecho - echo UDP packets

     SYNOPSIS
          ip/udpecho [ -x ext ]

     DESCRIPTION
          Listen on UDP port 7 and echo back any packets received.
          This should only be run for testing since it can be used to
          disguise the identity of someone doing a denial of service
          attack.
