Hello, In 2014 I submitted a patch to dhcpclient which allowed the use of Linux raw sockets: https://github.com/FreeRADIUS/freeradius-server/commit/7deeac78b8fc50cdcd4eb... But in the current 3.0.x HEAD the code does not exist anymore. :'( Has it been removed on purpose, or is it a mistake ? The code disappeared between the following two commits: 30 Aug 2015 https://github.com/FreeRADIUS/freeradius-server/blob/517b0cfa104d30c84316c7d... https://github.com/FreeRADIUS/freeradius-server/commit/517b0cfa104d30c84316c... => OK Sep 2, 2015 https://github.com/FreeRADIUS/freeradius-server/blob/5a806d0bd3439b32e089dd2... https://github.com/FreeRADIUS/freeradius-server/commit/5a806d0bd3439b32e089d... => The code was removed :'( Regards, Nicolas.
