Hi all, As you reply yesterday to my question, I have another one which is very embarrassing : I have the following packages installed on CentOS box : freeradius2.x86_64 freeradius2-mysql.x86_64 freeradius2-ldap.x86_64 freeradius2-perl.x86_64 freeradius2-utils.x86_64 I want to make some transformations on my accounting section but this doesn't work when I put the "perl" in accounting section. Radius stop working : /usr/sbin/radiusd -X conns: 0x25e9760 Module: Checking authorize {...} for more modules to load Module: Checking accounting {...} for more modules to load /etc/raddb/radiusd.conf[267]: Failed to find module "perl". /etc/raddb/radiusd.conf[263]: Errors parsing accounting section. I've found a lot of problems looking on my Google friend, but I didn't understand with a simple : accounting { # sql # comment perl } Using the simple configuration for modules found here: http://wiki.freeradius.org/Rlm_perl Does not work . Any ideas ? Thanks in advance for your help Regards, Fabien VINCENT
