Cannot use syslog

Hi, One last question. I would like to use syslog to log the activity of FreeRadius 3.0.15. My radius server is running chrooted and nothing shows in syslog despite I add a rule to log *.* in /var/log/all in syslog configuration. How FreeRadius is accessing syslog? Through the Unix socket (and then I need it in the chroot environment) of through the network stack? The server is FreeBSD. Thanks in advance, olivier --
