List, This is odd, I can't seem to figure out what the deal is with this. This works: As root user; /usr/sbin/radius -X As root user; /usr/sbin/radius (when user= and group= is commented out and running as root) As radius user; /usr/sbin/radius -X As radius user; /usr/sbin/radius (when user=radius and group=user) This doesn't work: As root user; /usr/sbin/radius (when user=radius and group=user) I don't think this is a permissions issue as it works fine when invoked as the radius user in daemon mode (so we can read the config and write to logs), but starting as root and letting radius switch to the radius user doesn't work. What is interesting is that the logs show: ....... Module: Checking preacct {...} for more modules to load Module: Checking accounting {...} for more modules to load Module: Checking post-auth {...} for more modules to load } # modules } # server When running as root user; /usr/sbin/radiusd -xx (when user=radius and group=user) So it stops just shy of thread pool and binding to the port. The same command and config run as the radius user shows: ....... Module: Checking preacct {...} for more modules to load Module: Checking accounting {...} for more modules to load Module: Checking post-auth {...} for more modules to load } # modules } # server thread pool { start_servers = 10 max_servers = 32 min_spare_servers = 3 max_spare_servers = 10 max_requests_per_server = 0 cleanup_delay = 5 max_queue_size = 65536 } Thread spawned new child 1.

Any ideas? Thanks, schu
