Hi all, Can anyone please help me get the control socket for radmin working on Ubuntu. I've built FreeRADIUS v3.0.21 debs from source and install the debs on Ubuntu 18.04. I then created some ssl certs and the default config starts up ok. I then add a symlink to turn on the control-socket and sudo freeradius -X gives the error: Failed creating control socket "/var/run/freeradius/freeradius.sock": Failed creating control socket directory: Permission denied I know the service startup has comments about the directory creation not working on Ubuntu Bionic (18.04). So I've tried creating /usr/lib/tmpfiles.d/freeradius.conf containing: 'd /var/run/freeradius 0755 freerad freerad -' Ran sudo systemd-tmpfiles --create but no /var/run/freeradius Rebooted and no /var/run/freeradius sudo freeradius -X gives same error (as above). Anyone know how to get the control-socket to start correctly on Bionic? I've also tried on Ubuntu 16.04 and get the same issue, but I rather fix on 18.04 if poss. Many thanks all, Kev/.
