Hi Sean,
the patch to change the static declaration of struct ifreq ifr into a non
static declaration should be done in any case. I had suspected the issue should
disappear then but as Vyom told otherwise, I'll also try to test this.
As for the test: NetworkInterface.getNetworkInterfaces() will return a typed
enumeration, so you could iterate like:
for (NetworkInterface ni : NetworkInterface.getNetworkInterfaces()) {
...
}
Then the code would be more compact.
I'll get back to you with the results of my testing.
Best regards
Christoph
