Finding local IP addresses using Python's stdlib
...
The "update" shows a nice trick with connect() on a UDP socket. It sends no traffic but does let you find what would be the sender address for packets to the specified recipient. The port is likely irrelevant (even 0 should work). On a multihomed host it's important to pick an...
What is “overhead”?
... actual data. You can reduce the overhead by using larger packet sizes and UDP has a smaller header and no handshake.
Data structure memory overhead: A linked list requires at least one pointer for each element it contains. If the elements are the same size as a pointer, this means a 50% memory over...

Test if remote TCP port is open from a shell script
