Description Tim Creech 2013-09-10 20:53:23 UTC 
The bind to 255.255.255.255 fails on FreeBSD. kdeconnect might eventually allow the user to choose an interface, compute its broadcast address, and then do directed broadcasts (e.g., 192.168.0.255) there. Maybe someone knows of a way to convince FreeBSD to do the undirected broadcast with Qt?

Hack/workaround: FreeBSD users can change (hard code) QHostAddress("255.255.255.255") and QHostAddress::Broadcast to QHostAddress("192.168.0.255"), or similar.

Reproducible: Always

Steps to Reproduce:
1) kded4 --nofork

Actual Results:  
Note via debug messages that the FreeBSD desktop never hears any broadcasts


FreeBSD 9.1-RELEASE-p7

Well, I have no experience at all on non-linux systems, so I hope another FreeBSD user can helps you. Meanwhile, consider KDE Connect "unsuported" on FreeBSD :(

LanLinkProvider: Bind the UDP server socket to Any, not Broadcast.

Trying to bind a UDP socket to 255.255.255.255 fails with EADDRNOTAVAIL
at least on FreeBSD.

The sender side on Android should send its message in broadcast mode (as
it already does), but the receiver side should bind to INADDR_ANY, not
INADDR_BROADCAST.
