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.
                                                                    UDPECHO(8)
