Module local_ip_utils

Functions

• get_available_port
  Return an ephemeral, available port. On unix systems, the port returned will be in the TIME_WAIT state ensuring that the OS won’t hand out this port for some grace period. Callers should be able to bind to this port given they use SO_REUSEADDR.

  In non-simtest, we always only have one IP address which is localhost.
• localhost_for_testing
  Returns localhost, which is always 127.0.0.1.

• new_local_tcp_socket_for_testing
  Returns a new unique TCP address (SocketAddr) for localhost, by finding a new available port on localhost.
