This Howto is for those users still tinkering with the Informix SE Database engine and would like to have a go at Authenticating and sending Accounting logs to this type of server. It assumes that your knowledge of Unix and Informix is fair as I have only touched on the parts that will cause you grief it is not a complete manual. Software used - freeradius-1.0.0 (The Radius Server) http://www.freeradius.org Informix 7.x unixODBC-2.2.5-ansi (To conect to the Database server) http://www.unixodbc.org
- Informix TablesSet up you Informix as normal on the Database server. Make sure you can connect to the server with dbaccess. Now build the tables requied for Freeradius. I used the following sql files which have been taking from the Free Radius distribution and altered for Informix radinformix.sql (you may want to change the AcctInputOctets & AcctOutputOctets to suite your requirements).
- InformixInstall your informix connectors to this server. Make sure you can connect from this server to your main database server. If you cannot, check your hosts.equiv or .rhosts or sqlhosts.
- Unix OdbcMAKE SURE YOU DOWNLOAD THE RIGHT VERSION. (The ANSI version). From there the installation is pretty straight forward install the Unixodbc as per instructions and create both odbcinst.ini - [ODBC] Trace = No TraceFile = /tmp/odbc.log ForceTrace = No Pooling = No FileUsage = 1 [Informix] Description = Informix Driver = /usr/informix/lib/cli/libifcli.so APILevel = 1 ConnectFunctions = YYY DriverODBCVer = 03.00 FileUsage = 1 smProcessPerConnect = Y odbc.ini - [radius] Driver=Informix Description=Informix Trace=No TraceFile=/tmp/odbc.log Server=demo_se Database=radius LogonID=mylogin pwd=mypasswd CLIENT_LOCALE=en_us.8859-1 DB_LOCALE=en_us.8859-1 TRANSLATIONDLL=/usr/informix/lib/esql/igo4a304.so Port=myport You should be able to test this now with - >isql radius This should connect you to your database. >help radacct Should show you your radacct table. If not check the following - ODBCINI (environment variable) sqlhost hosts.equiv .rhosts
- Radius ServerThis is pretty much stock standard. The main problem is that after the radius server queries the database for an attribute it is returned with the trailing white space. This needs to be stripped. I have added code to sql.c in the rlm_sql modules which calls trimStr Sql.c (for freeradius1.0.0) After changing/copying this code. Compile freeradius as normal and install. Install the rlm_sql and driver for iodbc. Your sql.conf file in the freeradius will need a little editing I have provided on here if you require assitance. sql.conf Once all is configured you will need to make sure you have any extra environment variables added to your radius startup script. Now fire it up..
