Incoming is a packet monitor designed to monitor SYN packets. Machines receive SYN packets when a remote machine is trying to initiate a TCP connection.

When a machine is listening on a port, it replies the machine sending the SYN packet with an aknowledgement ( ACK ) request. If the machine is not listening on a particular port, then the machine will reply with a reset ( RST ) request.

Many crackers use the SYN scan technique to detect open ports. This helps the crackers easily detect the services r...

You may check communication with computer or look up if a host is online by executing a ping command. Windows does not provide graphical utility to do that, but has a command line tool. This software works just like command line ping.exe but has a configurable parameters screen and a nice graphical output. You may preset TTL - time to live of the ICMP packet to be sent, the size of the ICMP packet to send, number of ping requests, host name resolution, packet size. The software can run both using ICMP or Wi...
