You got the logic wrong: typically you want to serve each client in a
separate thread.  Try this:

require 'socket'

SERVER_PORT = 4772
LISTEN_ON = '0.0.0.0'

server = TCPServer.new LISTEN_ON, SERVER_PORT
clients = 0

while true
  Thread.new( server.accept, clients += 1 ) do |con, clnt|
    puts "Connect with client #{clnt}"
    while ( line = ( con.gets ) )
      puts "From client #{clnt}: #{line}"
    end
    puts "EOF #{clnt}"
  end
end

Note: I introduced "clients" and "clnt" just for the purpose of
distinguishing output from different clients.

Kind regards
