Hello,

 

ah, good find, thanks for sharing the solution.

 

The module seems to just use the rc_read_config option, not sure if this allows the addition of additional log messages. But a comment to the module docs could of course be added.

 

Cheers,

 

Henning

Subject: [SR-Users] Re: [auth_radius.c:123]: mod_init(): failed to open configuration file

 

Hello!

 

Figured out the source of the problem.
The radiusclient-ng library didn't like the radius_deadtime option (which has been migrated from the freeradius-client library), commented it out and everything works.

Maybe it makes sense to add additional logging to the configuration file to avoid such problems?

 

/etc/radiusclient-ng/radiusclient.conf

...

#radius_deadtime 30
...

In this commit, the radius library was changed specifically for the version of Centos 7:

As far as I can see, the new version of Kamailio requires radiusclient-ng, although the current one old worked with freeradius-client.
Maybe there is a reason?

That's exactly what it is, in two cases the operating system and the radius library are the same, only the difference is in the version of Kamailio.

 

CentOS Linux release 7.9.2009 (Core)

freeradius-utils-3.0.13-15.el7.x86_64
freeradius-3.0.13-15.el7.x86_64
freeradius-client-1.1.7-16.el7.centos.x86_64

 

I connected via strace to kamailio 5.6.4, maybe this output will somehow clarify the situation:

Indeed, that commit should not change anything.

Looking at the code, it is rc_read_config() that fails -- this is not a
function implemented inside kamailio, being from radius client library.

Is it the same radius client library used for the two test cases? It is
the same operating system? In other words, have you tried with the two
version on exactly the same system?

Cheers,
Daniel
