I am trying to run some very short simple TCP and UDP portable network socket code examples from various tutorials. The examples just try to send or receive one UDP or TCP packet. The example code run just fine on Raspberry Pi's, and can send 1 byte of data between two of them.
When on macOS Big Sur I compile and run this code from the Terminal command line,
An error box pops up saying:
There is a button to cancel, disable identity check, deny (in red), and accept the modification. Hitting disable identity check or accept does nothing, the box stays on top. Hit deny, and a.out quits without sending any network data.
IIRC, code similar to these examples ran under Mohave without any pop-ups appearing.
Is there way to run simple network socket code on Big Sur.
