Hello,

I would like to run multiple RADIUS servers (FreeRADIUS) on a single machine on different ports. Does anybody have an idea how I can cleanly do that ?

Thank you very much in advance for your assistance.

Regards,

Chris

try this:

Once you have FreeRADIUS running, you need to test the configuration to make sure it is responding to requests. FreeRADIUS starts up listening, by default, on the port specified either in the local /etc/services file or in the port directive in radiusd.conf. While RFC 2138 defines the standard RADIUS port to be 1812, historically RADIUS client equipment has used port 1645. Communicating via two different ports is obviously troublesome, so many users start the FreeRADIUS daemon with the -p flag, which overrides the setting in both the /etc/services file and anything set in radiusd.conf. To do this, run the following from the command line:

radius:/etc/raddb # radiusd -p 1645
radiusd: Starting - reading configuration files ...
radius:/etc/raddb #

Hi dd12,

thank you for your answer.

the problem is that if I run a second radius entity, lets say first "radiusd -p 1645" and afterwards "radiusd -p 1756" the second call will simply stop the first and the server will only listen to the port assigned in the second call, so 1756. ;-(

I even tried to duplicate the /usr/sbin/radiusd to /usr/sbin/radiusd1 and /usr/sbin/radiusd2. Also the /etc/init.d/radiusd, duplicated, created two completely seperate configuration pathes (out of /etc/raddb) and modified the path settings in the /etc/init.d/radiusd1 and /etc/init.d/radiusd2. Then using different port settings in radius.conf. But it also has the same effect: The second call is ending the first one.

I understand.

Does /var/log or /var/log/radacct or syslog show any killing of 1st instance?
