I am trying to setup up freeradius as dchp server. Everything is Ok,
exempt broadcast packets (dhcp offers) are not leaving the server interface.
I use Ubuntu 14.04.2 LTS (GNU/Linux 3.13.0-45-generic i686) and
FreeRADIUS Version 2.2.7,compiled from git v2.x.x sources.
Firewall is off, radiusd runs as root.
strace shows some sendto() errors like: EACCES (Permission denied)
and EINVAL (Invalid argument).
The EINVAL (Invalid argument) could be fixed with
"--without-udpfromto" compile option.
The full details are available at http://pastebin.com/625BEbr1
I have not a programmer at all, but my suspicion is that send socket
option SO_BROADCAST is not set ... not sure. Unicast replies are Ok.
My questions are: what else should I check? is there any workaround for
