What type of defect/bug is this?

Unexpected behaviour (obvious or verified by project member)

How can the issue be reproduced?

Hello.
I'm having problems with checkrad script and NAS with IPv6 address. I use Freeradius with MySQL.

Authentication, authorization and accouting work normally. Radclient disconnects the user normally.

The problem occurs when it is necessary to run the verification of simultaneous users, using the checkrad script. I am having the following error message:

checkrad: Unknown NAS 2901:452:9:a::2, not checking

In the MySQL nas table is the IP 2901:452:9:a::2 (remembering that the authentications are working normally with this configuration).

(remembering that the authentications are working normally with this configuration).

If you use IPv4 as the NAS address, the checkrad works normally. The problem with checkrad only occurs when using IPv6 as the NAS address.

I compiled the latest version of FreeRadius 3.2.

Could someone help please?
Thanks

The message Unknown NAS .., not checking is because that IP isn't listed as a RADIUS client.

Maybe you have the client tied to a virtual server? checkrad only works with global clients, which are usually defined in clients.conf.

You might try listing that IP address in clients.conf, and seeing it it helps.

Hello Allan, how are you? Thanks for your reply.

I ran the following tests:

  1. I commented out the option "read_clients = yes" inside the SQL module. This way Freeradius will no longer use the MySQL "nas" table.

  2. I created at the end of the clients.conf file:

client test_ipv6 {
ipv6addr = 2901:452:9:a::2
secret = secret
}
  1. Authentication, accounting and disconnection work normally. But the simultaneous connection test returns the same error:

checkrad: Unknown NAS 2901:452:9:a::2, not checking

  1. I changed the clients.conf file to the IPv4 I have on the same router:
client test_ipv6 {
         ipaddr = 200.200.200.1
         secret = secret
}

Everything works normally.

It seems to me that the behavior is the same, both using MySQL and clients.conf: when the NAS has IPv6, the checkrad script does not recognize it.

Hope this helps
Best Regards
Fabricio

Hello.

I just did some tests and the problem continues to occur:

checkrad: Unknown NAS (my NAS IPv6), not checking

Authentication and accouting are working normally.

In the session.c file we can see the call:

cl = client_find_old(nasaddr);

The client_find_old function is in the client.c file.

It calls the client_find function passing root_clients.

When it is IPv6, the line below does not find anything:

data = rbtree_finddata(clients->trees[i], &myclient);

However, when it is IPv4 it works normally.

However, the client_find function is used in the listen.c and stats.c files. In these places it works normally, that is, in the case of listen.c it recognizes the packet that arrives from a NAS with IPv4 or IPv6.

I may be mistaken, but it seems to me that the client_find function is working. The problem only occurs when we pass root_clients to it.

Maybe something is wrong when creating root_clients.

I used the latest version of the 3.2.x branch for testing.

I hope this information has helped and that it helps you solve this problem, as all that remains is to resolve this issue so that IPv6 can be implemented without any problems!
