YRadius

YRadius Module adds support for RADIUS in Yate to bill calls using well known RADIUS billing mechanism.

The yradius module requires the cdrbuild module.

[edit] RADIUS Attributes

YRadius supports both Authentication (may be Authorization is the best term there) and Accounting. It doesn't support Authentification (Registration) yet.

It supports following RADIUS attributes:

 User-Name
 User-Password
 NAS-IP-Address
 NAS-Port
 Vendor-Specific (only for CISCO's h323-conf-id)
 Session-Timeout
 Called-Station-Id
 Calling-Station-Id
 NAS-Identifier
 Acct-Status-Type
 Acct-Delay-Time
 Acct-Session-Id
 Acct-Session-Time

The h323-conf-id is the billing id used by YATE.

You can add as many RADIUS servers you want.

[edit] Configuration File

Configuration has 3 sections:

• First one is general specifying the IDs of NAS.
• The second section is for NAS. Each NAS section is named with words nasN' where N is the number of nas in this configuration, like nas1, nas2, nas3 ... nasN.
• The last section is RADIUS. The radius section is for radius server, it follows similar pattern and should contain radius1, radius2, radius3 ... radiusN, respectively.

Right now one server is supported for each NAS. Option to have more backup servers will be added soon. Although you can reference same radius server sections more than once in different NAS sections.

[edit] Disabling Accounting or Authentication

By default a radius section would have both authentication and accounting enabled. But this can be controlled by disabling the feature you don't want.

If you only want to bill then use:

  disable_auth=on

Comprehensive yradius.conf

[general]
nas_id=yatenas           ; identifier for this NAS
nas_ip=192.168.0.2       ; ip address of this nas
nas_port=5062            ; port to use for listening (can be anything)
priority=55


[nas1]
called_num=^1234\(.*\)$  ; number to match for authenticating/billing.
radsec=radius1           ; name of section containing info about RADIUS server, defined later
authfailnum=1235         ; number to route to if authfails.
autherrnum=1236          ; number to route to if some other error occurs

[radius1]
server=192.168.0.2       ; address of RADIUS server
auth_port=1812           ; auth port for radius server
acct_port=1813           ; acct port for radius server
secret=nassecret         ; shared secret with RADIUS server
;disable_auth=on         ; disable auth for this radius server
;disable_acct=on         ; disable accounting for this radius server
timeoutsecs = 5          ; timeout for receiving reply from server
retries = 2              ; retries to send auth or acct packets
