radiusd: memory use problem
by German Hernandez 07 Feb '07

07 Feb '07

Hi! I need please your help about this problem: we have working RADIUS Server (FreeRADIUS) with OpenLDAP like users database and MySQL for accounting; Serving WLAN users, with about 5,000 connections every day. FreeRadius and MySQL at the same Computer. radiusd usually use beetwen 0.5 and 3.0 of %MEM, but sometimes memory use (by radiusd) begins to increase; for example, some times in one week of 0.5 %MEM it arrives until 40 %MEM, then I need to restart the radiusd daemon. Somebody could help me? Thanks in advance German Common errors from radius.log: ...

Again: Major impact on authentication!
by Guilherme Franco 07 Feb '07

07 Feb '07

Hello, Thanks to everyone! I'm using Oracle just for radcheck/radacct and PostgreSQL for radippool only. No, Mr. Peter, no one is using dial-up admin nor anything alike when the problem occurs, just pure auth (without acct). I've disabled the cron.hourly job and the problem appeared again after some hours. A simple radiusd restart solves the problem. As this causes impact, I can't afford to do this all the time just to debug, but I think I gonna run a script to capture all the radiusd -xxx messages, so when the behaviour starts, I can see what's happening. Also, it's important to note that this server is the proxy radius and those error messages appear: Error: Discarding duplicate request from client ERX-1:50000 - ID: 115 due to unfinished request 32 Info: The maximum number of threads (32) are active, cannot spawn new thread to handle request Error: WARNING: Unresponsive child (id 1315006816) for request 105 With acct: Error: rlm_sql (sql) in sql_accounting: stop packet with zero session length. [user 'joe.black(a)foo.com', nas '10.10.2.1'] Error: Internal error processing module entry Thank you.

Management of temporary users
by Nick Owen 07 Feb '07

07 Feb '07

Greetings: I am looking for the best way to provision groups of users for temporary access across multiple servers. The users would be using ssh and sudo. They would be assigned to a group of servers, then removed after the job was complete. There a hundreds of servers involved. I was thinking that I could use freeradius with dialup_admin to quickly add and remove users from huntgroup, but it doesn't appear that huntgroups are supported in dialup_admin, or am I missing something? Any suggestions welcome.

counter module usage question
by tzieleniewski 06 Feb '07

06 Feb '07

Hi!! I am trying to utilize the counter module. I tried to do everything as it is written in the comments from the radiusd.conf file. unfortunately I still have some problem to make it work and fully understand. I ask for your assistance and small explanation. As I understood the counter modules generally controls the login process of the users, where logging is equivalent of sending a request to the radius server. So whenever the request is received by radius the module investigates the content of the packet. It checks if there are parameters corresponding to the 'count-attribute' and 'key' parameters defined for that module. Then if they are present it creates a counter which is stored in the 'filename' file. Then it updates the value of the 'counter-name' parameter which will be passed further with the packet. So now if I want to control the process further I need to make the proper modification in the users file against the value of the parameter pointed by the check-name parameter from the counter module configuration, am I right? Is there a way to somehow set the default value for 'check-name' parameter in the module configuration in the radiusd.conf? Thank You for your time!! tomasz

Hibernating: Major impact on authentication!
by Guilherme Franco 06 Feb '07

06 Feb '07

Hello, Considering that all things indicate that there might be a problem with the DB, I did some tweaks in PostgreSQL and took off the cron.hourly job. Gonna watch out for problems then, thanks! --------------------------------------------------------- Hi, Freeradius 1.1.4 is randomly losing connection to both databases and it's causing total loss in the authentication process: Info: rlm_sql (sql): There are no DB handles to use! skipped 0, tried to connect 0 Info: rlm_sql (sql_postgresql): There are no DB handles to use! skipped 0, tried to connect 0 Info: The maximum number of threads (32) are active, cannot spawn new thread to handle request Running either in multi or single threaded mode, that messages appeared 47.099,00 times since Jan 27! Freeradius is configured with 32 max_servers and 32 connections to each DB. There's no starving since no accounting is being used and the server have to handle just 3 auths per second. Every time this happens, no one can authenticate and doing a restart in Freeradius solves the problem. To circumvent the problem, I've added a cron.hourly job so each hour a "service radiusd restart" is issued. As this is random, it's hard to debug, but at the same time freeradius loses the connection, several other applications can successfully connect/ maintain previous established connections to the databases. I've enabled all sorts of debug in the databases trying to better understand why freeradius is doing this, but there was no luck. I've installed the latest CVS and the same problem appeared, please help!

a3Com
by diego＠gigadata.it 06 Feb '07

06 Feb '07

I have a lot of problems with RADA authentication. When I start my tests the NAS (a stack of 4 3com 4400 24 port switches in a network of 100 switches) sends access requests to 2 freeradius servers (primary and secondary) asking for user authentication. All seems to work right (the radius servers reply requests sending "Login OK" after checking if username/password = MACaddress/MACaddress are in MySql database) but at one moment, the NAS sends the Access-Request with username a3Com and password a3Com. I added account a3Com/a3Com in database, and the radius servers answer "Login OK: [a3Com]", but the NAS go down with a warning that sounds like : "The RADIUS Authentication service is not responding". What is the mistake? Freeradius? 3com 4400 Switch? MySql? Debian? Netwok? Me? this is NAS request rad_recv: Access-Request packet from host 10.10.0.x:2049, id=57, length=87 User-Name = "a3Com" User-Password = "a3Com" NAS-Port-Type = Virtual NAS-IP-Address = 10.10.0.x Service-Type = Administrative-User Framed-MTU = 1024 Message-Authenticator = 0xebe2ebda3372940ad56d932c10457ff8 Processing the authorize section of radiusd.conf Diego Torto
