>Description:
The built-in echo service of inetd only echoes UDP packets up to 8K
in length. This is not really in conformance with RFC862, which
specifies no such length limit (ftp://ftp.isi.edu/in-notes/rfc862.txt):

UDP Based Echo Service

   Another echo service is defined as a datagram based application on
   UDP.  A server listens for UDP datagrams on UDP port 7.  When a
   datagram is received, the data from it is sent back in an answering
   datagram.
