Do you mean mac\_conf.each\_with\_index { |mac, aplist|…?

I think your problem line should be changed to

macaddr.each { |mac, aplist| puts “\n ALERT!\t\n An Imitation of MAC  
address  
#{mac} were found \>\> #{aplist.inspect}” if aplist.size \> 1}

(Note in particular that you iterate over the hash ‘macaddr’, not the  
closed IO object mac\_conf, and since aplist is an array you need to  
check aplist.size)
