hi, i try to install version 3.0.18 on Debian 9. I have successfully used this tutorial: [1]https://wiki.freeradius.org/building/Debian-and-Ubuntu After that i can start freeradius by hand (freeradius -X). But not with systemd: $ systemctl start freeradius.service Job for freeradius.service failed because the control process exited with error code. See "systemctl status freeradius.service" and "journalctl -xe" for details. $ systemctl status freeradius.service freeradius.service - FreeRADIUS multi-protocol policy server Loaded: loaded (/lib/systemd/system/freeradius.service; enabled; vendor preset: en Active: activating (auto-restart) (Result: exit-code) since Sat 2019-03-02 08:23:2 Docs: man:radiusd(8) man:radiusd.conf(5) [2]http://wiki.freeradius.org/ [3]http://networkradius.com/doc/ Process: 2973 ExecStart=/usr/sbin/freeradius $FREERADIUS_OPTIONS (code=exited, stat Process: 2971 ExecStartPre=/usr/sbin/freeradius $FREERADIUS_OPTIONS -Cx -lstdout (c Main PID: 2973 (code=exited, status=1/FAILURE) Mär 02 08:23:24 test systemd[1]: Failed to start FreeRADIUS multi-protocol policy ser Mär 02 08:23:24 test systemd[1]: freeradius.service: Unit entered failed state.
