code: def connect(node)
        @node = node
  
        @node.model.cfg['tftp'].each { |cb| instance_exec(&cb) }
        @log = File.open(Oxidized::Config::Log + "/#{@node.ip}-tftp", 'w') if Oxidized.config.input.debug?
        @tftp = Net::TFTP.new @node.ip
      end
docs: TFTP utilizes UDP, there is not a connection. We simply specify an IP and send/receive data.
