Tcping is an alternative to icmp ping as nowadays most network administrators have banned inbound icmp traffic to their Internet hosts for security reason. Tcping does not use icmp, rather it uses tcp sync, ack and nop (no operation) to complete the two way connection sequences. It could be used to determine the round trip time to a host and also testing whether a host is live or not.

Tcping requires a port number in addition to the destination IP address when initiating the command.

Tcping in Linux can be found everywhere on the Internet. It is difficult to find Windows-based tcping. Fortunately, I've got one.
