Correct me if I'm wrong 1.When the syn get syn,ack response it means port is open. 2.When the syn not get any response it means server not responding. 3.When the syn get rst,ack response it means port is closed.
Hi @Vijay-fb9wh 1) Yes, that port is open on the server. 2) It could mean the server is not responding (but it could also mean it never received the SYN from the host. 3) Yes, that port is closed. Hope this helps!
@@netallynetworktestingtools hey @vijay-fb9wh just one little point to add. For the second question, usually when we send a SYN with Nmap and don't get a response at all, the output will say "Filtered" - so it is most likely that a firewall blocked the syn and did not return anything (which is normal). Network congestion could have caused the SYN to be dropped as well, so there are a couple possibilities there.
Great video, I found it very useful and easy to follow.
Good to hear, thank you for the feedback!
