be a sign or warning that (something, especially something momentous or calamitous) is likely to happen.
Use portend to monitor TCP ports for bound or unbound states.
For example, to wait for a port to be occupied, timing out after 3 seconds:
portend.wait_for_occupied_port(‘www.google.com’, 80, timeout=3)
Or to wait for a port to be free, timing out after 5 seconds:
portend.wait_for_free_port(‘::1’, 80, timeout=5)
