questions about 3.0.7 under load using file listen server
by adrian.p.smith＠bt.com 19 Mar '15

19 Mar '15

We are running 3.0.7 and writing packets to a file to be read by a detail server. We find that, when the server is under a lot of client load the detail server stops working. When the load reduces, the detail server resumes sending packets. Is this a deliberate design? We didn't see that with earlier versions. Perhaps there is some config we can adjust? Thanks in advance.

Hi I am new in Freeradius and i am search a small help. - I receive a Radius Access request of the radius of my supplier. this Radius have the ip address 192.168.10.100 - Based on the realm, i forward the request to my customer. i want add in the process a action before sent the request to my customer. Actually i have: in proxy.conf home_server rad-auth-primaire-1.customer_realm.myrealm { type = auth ipaddr = 172.16.1.1 port = 1812 secret = password require_message_authenticator = yes response_window = 20 zombie_period = 40 status_check = status-server check_interval = 20 num_answers_to_alive = 3 } home_server_pool pool-auth.customer_realm.myrealm { type = fail-over home_server = rad-auth-primaire-1.customer_realm.myrealm home_server = rad-auth-secondaire-1.customer_realm.myrealm } realm "~(customer_realm.myrealm)" { auth_pool = pool-auth.customer_realm.myrealm nostrip } i want add this action: Before sent the access request to my customer, i want that my radius answer to the radius server of my supplier a Access-Accept with a: Tunnel-Server-Endpoint:0 = "172.17.10.250" With this information, my supplier sent the tunnel to 172.17.10.250, it's a Cisco router, when i receive the tunnel he sent a access request to my radius and i want that my radius forward the request to the radius server of my customer with a : NAS-IP-Address = 172.17.10.250 It's possible ? CPE Customer ==> My_Cisco_172.17.10.250 ==> Cisco of my Customer (replied in radius tunnel end point) I don't know what file i modify for this, policy.conf ? other ? very very new ;=) thanks for your help Olivier

Hi, I'm running freeradius 3.0.6. I'm already able to assign a VLAN to the port when my client is authenticated with a couple login/password but is it possible to be done when the client is authenticated via a certificate ? I can't find any ressources on the subject. Thank's for help. *MOUGENEL Gérold* Tel : 06.71.58.47.57

errors after migration
by Brian 19 Mar '15

19 Mar '15

Hello, I recently migrated my Radius server to a new machine but it's giving me errors now when I try to start it. I had to change permissions in /etc/raddb to 755 in order to get it to start (even 750 wouldn't work) but I know that isn't an ideal long-term solution. I am on CentOS 6.5 with FreeRadius version 2.1.12. Thanks in advance.

sql or radtmp - which best?
by Marcin 19 Mar '15

19 Mar '15

Hi, I starting with freeradius 2.4 with flat files. I've heard that freeradius with flat files works faster than works with sql (postgres or mysql). Which should i chose to accounting users, sql or files? maybye both? In some documents I've read that accountigs should be stored with two tables. one table to online sessions and second table to archive data, but how to split it? In that case when client disconnects i should use two questions to database with different tables, one to delete online sessions and second to insert data to "archive" table. but when we use database we should replicate data, how to synchronize databases? What are the best practices to store users, nas and accounting data, sql or files? -- Pozdrawiam Marcin / nicraM

Hi! Experts I want to achieve user traffic volume limit per month, but found there is a limit for user traffic to exceed 4Gbytes.
