A client node sends an SYN data packet over an IP network to a server on the same or an external network.

It is a three-step method that requires both the client and server to exchange SYN and ACK (acknowledgment) packets before actual data communication begins.Ī three-way handshake is primarily used to create a TCP socket connection.

linux: Ī three-way handshake is a method used in a TCP/IP network to create a connection between a local host/client and server.

Different OS has open dependent ports listed below. The ports differ in the operating system in which you are using. This method has a pre-assumption that the hosts on the networks are open ports and we have to guess which port is open or not. To overcome the demerits of echo request method, TCP scan method is introduced which works on three-way handshake method. Note: Personal firewalls or general firewalls are often set to so called “stealth mode” which is used not to react to ICMP echo requests. If the echo is received, that means the host is connected and in case, no echo is received, then it looks like that the host is down. This code iterates over all the available IP addresses, ping them and check for the reply.
