Ping TCP port with tcping
tcping is a tool that allows to verify reachability of TCP port.
The purpose of this tool is to allow for a monitoring of reachability
of specific service on remote (or local) host.
Unlike standard ping, fping or hping, this tool uses simple TCP
connection to verify if port is listening and is agnostic of application
protocols etc.
Each check will simply open a connection and if successful it will
immediately close it. While some applications may not like this, most
will handle this will and will not cause any significant resource
consumption.
