Hi, I am using the git versions of 3.x, and I *think* that maybe for a month, there has been a bug that prevents freeradius to boot it in Debian 7 if control-socket is configured. I have tried this with a copy of my configuration, and with a pristine copy of freeradius, which only got inserted the link to activate control socket into sites-enabled. Without control-socket all is well: without control socket: root@x:/etc/freeradius/sites-enabled# /etc/init.d/freeradius start [ ok ] Starting FreeRADIUS daemon: freeradius. root@x:/etc/freeradius/sites-enabled# The errors are: root@x:/home/rui# /etc/init.d/freeradius start [FAIL] Starting FreeRADIUS daemon: freeradius failed! root@x:/home/rui# /etc/init.d/freeradius restart [....] Checking FreeRADIUS daemon configuration...Trace/breakpoint trap failed (Debugger detected, raising SIGTRAP). #freeradius -X .... .... radiusd: #### Opening IP addresses and Ports #### listen { type = "control" listen { socket = "/var/run/freeradius/freeradius.sock" } /etc/freeradius/sites-enabled/control-socket[23]: No such server "(null)" Debugger detected, raising SIGTRAP Trace/breakpoint trap In /var/log/freeradius/radius.log, I only have: Mon Jul 28 12:13:35 2014 : Error: /etc/freeradius/sites-enabled/control-socket[23]: No such server "(null)" Regards, Rui Ribeiro ISCTE-IUL sysadmin
