rlm_expr(5)							 FreeRADIUS Module						       rlm_expr(5)

NAME

       rlm_expr - FreeRADIUS Module

DESCRIPTION

       The  rlm_expr module allows the server to perform limited mathematical calculations.  This module is not called directly in any section, it
       is invoked through the dynamic expansion of strings.

       For example, some NAS boxes send a NAS-Port attribute which is a 32-bit number composed of port, card,  and  interface,	all  in  different
       bytes.  To see these attributes split into pieces, you can have an entry in the 'users' file like:

       DEFAULT
	   Vendor-Interface = `%{expr: %{NAS-Port} / (256 * 256)}`,
	   Vendor-Card = `%{expr: (%{NAS-Port} / 256) %% 256}`,
	   Vendor-Port = `%{expr: %{NAS-Port} %% 256}`

       where the attributes Vendor-Interface, Vendor-Card, and Vendor-Port are attributes created by either you or a vendor-supplied dictionary.

       The methematical operators supported by the expression module are:

       +      addition

       -      subtraction

       /      division

       %%     modulo remainder

       *      multiplication

       &      boolean AND

       |      boolean OR

       ()     grouping of sub-expressions

       NOTE:  The  modulo remainder operator is '%%', and not '%'.  This is due to the '%' character being used as a special character for dynamic
       translation.

       NOTE: These operators do NOT have precedence.  The parsing of the input string, and the calculation of the answer, is done strictly left to
       right.  If you wish to order the expressions, you MUST group them into sub-expression, as shown in the previous example.

       All of the calculations are performed as unsigned 32-bit integers.

rlm_detail(5)							 FreeRADIUS Module						     rlm_detail(5)

NAME

       rlm_detail - FreeRADIUS Module

DESCRIPTION

       The rlm_detail module writes radius packets to 'detail' files.  It is primarily used for storing accounting information, but can be used in
       other sections to write packet details as well.

       The file format is similar to that of the old Livingston servers, and many 'detail' file parsers should work with FreeRADIUS.

       The main configuration items to be aware of are:

       detailfile
	      The file name in which to store the radius packet records.  NOTE: this variable is run through dynamic  string  expansion,  and  can
	      include FreeRADIUS variables to create a dynamic filename.

	    %{radacctdir}/%{Client-IP-Address}/detail-%Y%m

	    This will create one file per month, for each client.
	    This accomplishes 'file rotation' automatically from
	    within the server.

       detailperm
	      The file permissions of the detailfile.  If omitted, the default is 0600.

       dirperm
	      The directory permissions of the directory where the detail files are created.  The default is 0755.

       locking
	      This  option  is	set  to  'yes'	or  'no'.   By default it is 'no'.  Set this to yes to enable file locking, which is used with the
	      'radrelay' program.

CONFIGURATION

       modules {
	 ...
	 detail {
	   detailfile = %A/%{Client-IP-Address}/detail-%Y%m
	   detailperm = 0600
	   dirperm = 0755
	   locking = no
	 }
	 ...
       }
	 ...
       accounting {
	...
	detail
	...
       }

SECTIONS

       authorization, accounting, pre_proxy, post_proxy, post_authentication
