Hi Alex,

Hi Oliver,

Type into netcat, not the program I sent.
My program is the server and prints out whatever it recieves,
along with some other stuff that lets you know which options
are supported.

Nothing either.

$ date; nc localhost 8888 -u | ts
Wed Mar  6 14:09:38 CET 2024
foo
$ echo $?
0

Same here, but with nc forced to IPv4

	$ nc localhost 8888  -u -4
	a

And in the other window:

	$ ./a.out
cmsg recieved
data read: a
byte = 02

Regards,
Peter

$ cc testDgramSocketServer.c
$ date; ./a.out | ts
Wed Mar  6 14:09:05 CET 2024

Have a lovely day!
