Hello,I want to criate a program that send just the ack packet (like NMAP)to a determinate machine. What library I should use to manipulate this kind of packets? TKS guys!

    Why would behaving people do that - just send an ACK? Has there been a SYN? Are you going to wait for a SYNACK, are you going to be at least as rude as to send a FIN/RST?

    Will that be server or client code? or... something else? just some spoof for fun? What for?

    perl -le'print map{pack c,($-++?1:13)+ord}split//,ESEL'

    G'day meanroc,

    I'm wondering if perhaps you're looking for something like ping.

    If so, the core module Net::Ping may do what you want.
