portping is a small network utility to continually test connection to a TCP port. It has been tested on Debian GNU/Linux and Windows 10, but should work on others.
Version 1.7.5 was released on 2021-03-31.
NAME portping -- continually check if a TCP port is open SYNOPSIS portping [-p port] [-t] host DESCRIPTION For the host and port specified, portping will repeatedly attempt to open a TCP socket and then immediately disconnect. The arguments are: -p port The TCP port number to test. It will default to 3389, for Remote Desktop Protocol. -t Set the terminal title to host (useful when testing multiple hosts). host The hostname or IP address to connect to. If the port is open an exclamation mark (!) is printed, and if the port is closed a period (.) is printed. EXAMPLES portping -t -p 22 unix-server portping windows-server -p 3389 HISTORY In 2013 I needed a tool to let me know when I could restart RDP sessions to multiple Windows servers when installing updates in bulk. Ping would tell me when the network interface was up, but it could still be another few minutes before I could log in. portping was born from that frustration. AUTHORS Anthony Perkins <email@example.com>. BUGS Sometimes ports will be reported as down for one or more pings, even if the service is not down. Sometimes the terminal title is not reset to the previous value. This tool is intended to be a rough indicator, and should not be used to monitor service availability.
