Dears, I installed FreeRadius 3 on CentOS 7. I got this error message: # Instantiating module "post_proxy_log" from file /etc/raddb/mods-enabled/detail.log /etc/raddb/mods-config/sql/main/oracle/queries.conf[28]: Failed parsing expanded string: /etc/raddb/mods-config/sql/main/oracle/queries.conf[28]: ...ed-IP-Address}','%{Service-Type}','%{Acct-Input-Octets:-0}','%{Acct-Output-Octets:-0}','%{NA... /etc/raddb/mods-config/sql/main/oracle/queries.conf[28]: ^ Unknown module The Acct-Input-Octets considered as Unknown Module. I enabled "redis" and "rediswho" and installed redis-server .. even I think that "redis" is not the module that I missed. Kindly advice, why FreeRadius can not deal with "Acct-Input-Octets" ? What is the required module in mods-enabled that I should activate to use "Acct-Input-Octets" ? Best regards
