Hi All, 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 this issue? Thanks. Dmitri
