I wrote some test code, to enumerate the list of my interfaces of my laptop.
There are 3 (wired : eth0, wireless (wlan0), and the loopback (lo0).
WHen I run the test code, when only the wireless is active (so no wired connection), I get results like this :
Number of network interfaces is : 3
Interface 0
lo : lo
127.0.0.1
255.0.0.0
0.0.0.0
Interface 1
lo : lo
127.0.0.2
255.0.0.0
127.255.255.255
Interface 2
wlan0 : wlan0
192.168.0.103
255.255.255.0
192.168.0.255
Notice how Poco doesn't seem to find 'eth0' as 'eth0'.
Why I plug in the network cable I get :
Number of network interfaces is : 4
Interface 0
lo : lo
127.0.0.1
255.0.0.0
0.0.0.0
Interface 1
lo : lo
127.0.0.2
255.0.0.0
127.255.255.255
Interface 2
wlan0 : wlan0
192.168.0.103
255.255.255.0
192.168.0.255
Interface 3
eth0 : eth0
192.168.0.108
255.255.255.0
192.168.0.255
Is this a bug, or intended behavior. The documentation stipulates for the NetworkInterface::list() method : returns a list with ALL network interfaces on the system.
kind regards
