Spetnik TCPing "pings" a server on a specific port using TCP/IP by opening and closing a connection on the specified port. Results are returned in a similar fashion to that of Microsoft Windows Ping. This application is intended for use in testing for open ports on remote machines, or as an alternative to the standard "ping" in a case where ICMP packets are blocket or ignored. The following command-line options are supported: Unlimited ping, resolve ip address to hostname, custom number of requests, custom connect timeout, custom wait time between pings.
