three hand-shake

[meanroc]

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?

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.

Have a look at Net::Packet
