Hi Matthew, There is no any Freeradius instance running when I entered freeradius -X command. I checked it by ps -aux | grep radius. for eduroam I need to place two virtual servers eduroam and inner-tunnel into /sites-enabled directory. I configure eduroam virtual server to listen port 1812 and inner-tunnel to listen port 18120. But I still have problem with "address already in use" Regards, Talgat On Wednesday, January 9, 2019, 9:26:13 AM EST, Tal Nur via Freeradius-Users <freeradius-users@lists.freeradius.org> wrote: Hi All, I tried to setup Eduroam FreeRadius server for one institution in my country.
