Re: Bind socket?

24 Jun 2008

      I have removed the directory /usr/local/etc/raddb and rebooted the computer. After this i reinstalled freeradiusd not from cvs but with downloaded packet 2.0.5
Then when i called radiusd -X, all went well. 
The little probem is that i can't add ipaddr in section listen.
Here is the result:

Have you read the documentation in radiusd.conf regarding the listening address and port?
This part:
listen {
        type = auth
        ipaddr = *
        port = 1812
        interface = eth0
}

Try to play with these settings. set ipaddr to * or to the real ip address of the interface (like you have set now). Try with port "0" or "1812" and try to bind it to the correct interface. Try different settings and combinations. Also make sure you have your interface (eth0 or eth1) configured the right way. Check with command: # ifconfig

Your problem must lie in the listen{} part. If it still doesn't work, please post me your entire log of "radiusd -X".

Good luck!

Hello!
I am Sorry for the delay of my answer. 
When i  used the command ./configure>configure.log in radiusd directory this is what i have:
root@pio-desktop:/home/pio/radiusd# ./configure > configure.log

config.status: WARNING:  ./Make.inc.in seems to ignore the --datarootdir setting
config.status: WARNING:  ./src/include/build-radpaths-h.in seems to ignore the --datarootdir setting

configure: WARNING: the TNCS library isn't found!
configure: WARNING: silently not building rlm_eap_tnc.
configure: WARNING: FAILURE: rlm_eap_tnc requires:  -lTNCS.
configure: WARNING: silently not building rlm_eap_ikev2.

configure: WARNING: FAILURE: rlm_eap_ikev2 requires:  libeap-ikev2 EAPIKEv2/connector.h.
configure: WARNING: silently not building rlm_pam.
configure: WARNING: FAILURE: rlm_pam requires: 
 libpam.

So the rlm_exec library was compiled. 
Now when i boot with radiusd -X this is the result:

ERROR: Failed to open socket: cannot bind socket: Cannot assign requested address

/usr/local/etc/raddb/radiusd.conf[236]: Error binding to port for 192.168.2.15 port 1817

Please, What must i do?

Well, your first problem is that you don't have the module rlm_exec installed. Please recompile freeradius and look at the output from ./configure (e.g: # ./configure > configure.log) for compile errors because of dependency problems. Make sure everything that you want, is
 compiled with it. At least rlm_exec should be in the logs.

Furthermore, make sure that you bind radiusd to the right interface before starting it. The default config should immediatly work for you. Make sure the first time you run it, you do it with the default certicate. It generates a new one for you.

...If the default config doesn't work, you've compiled it wrong. Check dependencies!

yours,
jelle

2008/6/23 ELOM ETSE <infomario_007@yahoo.fr>:

I have stopped it as you say by rebooting the computer but no good result.
Is there another way to resolv this problem?

Your radiusd is still running. Stop it first before you start another pid.
