Adds a TCP port ping: ipx --ping --port N times a TCP connect to the port each round, for networks where ICMP is blocked or ping is not installed.
- Live line per probe:
reply(port open),port closed (RST)(host up, port closed) ortimeout. - Ends with a clear verdict:
✔ Port ping OK,! partly OK,! Host is up, port closedor✘ FAILED. Exit status is 0 only if the port answered as open. - TCP only (
-Ugives an error); no systempingneeded.
Also in this build since 1.0.0: nc-style --port check, -l PORT listener, -U, silent --live with q to quit, -o/--output, no TCP trace.
