supports many database back-ends such as flat-text files, SQL, LDAP, Perl, Python, etc. It also supports many authentication protocols such as PAP, CHAP, MS-CHAP(v2), HTTP Digest, and EAP (EAP-MD5, https://github.com/FreeRADIUS/freeradius-client/blob/master/src/radiusclient.c EAP-TLS, PEAP, EAP-TTLS, EAP-SIM, etc.). It also has fullsupport for Cisco's VLAN Query Protocol (VMPS) and DHCP. Please read the DEBUGGING section below. It contains instructions for quickly configuring the server for your local system. OPTIONS The following command-line options are accepted by the server: -C Check the configuration and exit immediately. If there is a problem reading the http://freeradius.org/radiusd/man/radiusd.html configuration, then the server will exit with a non-zero status code. If the configuration appears to be acceptable, then the server will exit with a zero status code. Note that there are limitations to this check. Due to the complexities involved in almost starting a RADIUS server, these checks are necessarily incomplete. The server can return a zero status code when run with -C, but may still exit with an error when run normally. See the output of radiusd -XC for an informative list of which modules are checked for correct configuration, and which modules are skipped, and therefore not checked. -d config directory Defaults to /etc/raddb. Radiusd looks here for its configuration files such as the dictionary and the users files. -f Do not fork, stay running as a foreground process. -h Print usage help information. -i ip-address Defines which IP address that the server uses for sending and receiving packets. If this command-line option is given, then the "bind_address" and all "listen{}" entries in radiusd.conf are ignored. This option MUST be used in conj

Always start with the "default" configuration. It will work everywhere, and do almost everything you need. The only change you will need to make http://www.kamailio.org/docs/openser-radius-1.0.x.html is to define users and passwords. Making a lot of changes to the configuration files is the best way to break the server. Don't do that. Define a Client error opening IP For initial testing from localhost with radtest, the server comes with a default definition for 127.0.0.1 and ::1 For testing from external machines, edit /etc/raddb/clients.conf and add an entry. There are many examples and the syntax is easy: client NAME { ipaddr = IPADDRESS secret = SECRET } Define a User and Password Edit /etc/raddb/users and create an example error opening config user account as the first entry. i.e. at the top of the file, such as: testing Cleartext-Password := "password" Start the server in debugging mode At this point you should be able to manually start radiusd. You should do this with the debugging enabled so that you can see what happens: $ radiusd -X The location and the name of the FreeRADIUS server executable may vary, for example it could be /usr/sbin/freeradius. But the -X parameter is essential, always use it! Lots of output will scroll by, and it will eventually say: Read to process requests. Sometimes people want to change default port to run on 1645, the old RADIUS port (the new one is 1812), if replacing a legacy RADIUS server. Other than that, it's possible that the EAP Module initial setup will fail. Simple test Once the FreeRADIUS server is operational, you can use radtest to test an account from the command line: $ radtest testing password localhost 0 testing123 Where testing is the user name configured above, and password is the password for the
SIP server (softswitch) and FreeRadius server as AAA server (backend). Warning The tutorial was written to be used with OpenSER v1.0.1 and FreeRadius v1.1.0 on a Debian unstable (sid) system. It can be used with other Linux/Unix distributions if you know the proper replacements for Debian specific tools (e.g., apt, GNU make). Table of Contents1. Overview2.

Document validity12. References1. Overview OpenSER (http://www.kamailio.org) is a scalable and flexible SIP (RFC3261) server with a lot of features that can power your VoIP services. Features like ENUM lookup, TLS support, authentication, authorization and accounting against database or Radius servers, least cost routing, load balancing or Call Processing Language allow providing residential or carrier VoIP services. FreeRADIUS (http://www.freeradius.org) is an open source RADIUS server.It scales from embedded systems with small amounts of memory, to systems with millions of users. It is fast, flexible, configurable, and supports many authentication servers. This document focuses on configuring FreeRadius to offer AAA services to OpenSER SIP server, needed for VoIP services. Step by step configuration is provided and you must be logged in as 'root' user to be able to execute the commands exampled in this document. It is assumed that you have basic knowledge about Linux or Debian operation and administration. 2. The architecture of the VoIP service Communication between VoIP users (phones) and the server uses the SIP (RFC3261) protocol. The SIP server will communicate with the AAA server via radius client, which is linked to the SIP server. Users' profile can be stored to the local file system (as it is done is the examples included in this document) or other storage system supported by AAA server (e.g., database, ldap). +---------+ +---------+ | PHONE 1 |<--SIP--+ +-------------------+ | STORAGE | +---
