Freeradius 3.0.4 Accounting [sql-relay problem]
by Ibrahim Almahfooz 04 Apr '16

04 Apr '16

Hi Everyone, We are currently running FreeRADIUS 3.0.4 as an accounting server installed from the repository on CentOS 7 server. We have almost 25k adsl,vdsl,gpon users in the network. The BRAS [NAS] is sending the accounting data to the FreeRADIUS. Instead of writing accounting data directly to the MySQL db, we configured it to write the sql statements to the sql-relay file and set a crontab to dump it to the remote db every 15 minutes using *radsqlrelay* command: radsqlrelay -x -h x.x.x.x -d mysql -b mysqldb -u root -pdbpassword -1 /var/log/radius/radacct/sql-relay While the above command run by the crontab, we see sql-relay.work file writing the background and we assume this is normal in order to write the incoming accounting data while doing the sql-relay transfer to the remote db. After a couple of days of setting everything, our [BRAS] NAS device has reported accounting errors in its statistics like accounting start not successfully sent or accounting stop not successfully sent and statistics shows the errors are happening randomly every one, two or six hours. We start doing investigations and found that in the radius.log there are many errors happening in the same time the radsqlrelay running by the crontab, the error is below: Fri Apr 1 03:59:23 2016 : Info: rlm_sql (sql): 0 of 3 connections in use.

We are not running any db in the same FreeRADIUS since we are writing to the file. Obviously, the FR server is considering sql-relay as database and report the error "Check that all databases are running properly!" Seems like the radius stops responding (not always) when dumping the sql-relay file to the mysql db. Also we sometimes see error of more than 50 requests have been waiting in the processing… in the radius.log. And that actually what triggers the NAS device to consider the freeRadius as down status. Surprisingly, our NAS start again sending accounting packet and the server goes normally. and this error keep showing on both radius.log and the NAS from now and then. And this probably means "Loss of accounting data" Actually we have no idea why this behaviour is occurring. We start thinking if there is any size or performance limitation in the sql-relay.work file? Or may be a bug in this version and we are unaware of the fix if exists? Any ideas?

FreeRADIUS 3 certificate issue on some Windows clients
by Tomáš Ivánek 04 Apr '16

04 Apr '16

I'm running FreeRADIUS 3.0.11 with OpenSSL 1.0.2g. I have successfully configured EAP TLS, TTLS and PEAP methods. Now the issue...when I'm configuring clients with Windows 7, Vista or XP and certificates are not yet installed (ca.der and optionally client.p12) and try to connect to the network through the bottom right network icon a bubble popup shows up telling me that I need to installl the certificates. The connection can't be established, which is how it should behave. When i configure the connection manually, import the certs, all the methods mentioned above works well. The manual configuration also work well on Windows 10 and can't connect until at least the ca.der is present on the computer for PEAP and TTLS. However when any of theese certificates are not present on the Windows 10 machine and try to connect through the network menu in the bottom right corner the connection is successfully created after entering login credentials. It seems like it's bypassing the ca.der certificate somehow. I have the same problem with windows phone 7.X devices. Is there a way how to prevent this behaviour? The server shouldn't allow the connection, am I right? here is the output od radiusd -X with example login through windows phone 7 device. It's a .txt file on my google drive. Thank you https://drive.google.com/file/d/0B9T3_pXPBXRnZklXRjJDcmVHek0/view?usp= sharing (https://drive.google.com/file/d/0B9T3_pXPBXRnZklXRjJDcmVHek0/view?usp=shari…)

two freeradius servers - question for advice
by Marcin 04 Apr '16

04 Apr '16

Hi everyone, I'm going to start two freeradius servers to authenticate PPPoE users, both independent of the other. First as primary and second as secondary. I'm going to start PostgreSQL server also, but in case of unavailability of sql server freeradius server must have work properly. Both freeradius have to have actual data of arleady logged users to provide simultanieusly use. I'm going to check authenticate in db and if if failed get user from files (created in background). accounitng i'm going to do with linelog and afterwards put in to database. I need advice from you, more advanced users than me. How to achieve that HA and avablitity. Thanks in advance. -- Best Regards Marcin / nicraM

This is not the case in FreeRadius version v3.1.x? Thanks, Kind regards, Katrien.

Freeradius 2.2.9 not works
by Mr Dini 04 Apr '16

04 Apr '16

Hi! I compiled the freeradius 2.2.9 on my nas and I configured a MySQL database for radius. It seems like works, but if I make a test connection from my router, it sends an Access-Reject package... If I make a radtest it also sends Access-Reject package, but if I edit the Cleartext-Password := guest1234 to Password == guest1234 it sends Access-Accept package... Why? What's wrong? Thanks for your answer!

New Install
by Cameron Murray 04 Apr '16

04 Apr '16

Guys, First time member and have a slight issue. Fresh Centos 6.7 64bit install and Freeradius installed with a remote MySQL server. Service launches perfectly in debug and daemon however it does not appear to be listening correctly. Netstat -a shows Radius and Radius Account open on * however when I query radius with radtest or radping it sees no data. udp 0 0 *:radius *:* udp 0 0 *:radius-acct *:* Iptables has been disabled and confirmed after reboot. I've tested radping from localhost and the Mysql Server with the same result: radtest test test 192.168.0.250 1812 123456789 Sending Access-Request of id 15 to 192.168.0.250 port 1812 User-Name = "test" User-Password = "test" NAS-IP-Address = 192.168.10.251 NAS-Port = 1812 Message-Authenticator = 0x00000000000000000000000000000000 Sending Access-Request of id 15 to 192.168.0.250 port 1812 User-Name = "test" User-Password = "test" NAS-IP-Address = 192.168.10.251 NAS-Port = 1812 Message-Authenticator = 0x00000000000000000000000000000000 Sending Access-Request of id 15 to 192.168.0.250 port 1812 User-Name = "test" User-Password = "test" NAS-IP-Address = 192.168.10.251 NAS-Port = 1812 Message-Authenticator = 0x00000000000000000000000000000000 radclient: no response from server for ID 15 socket 3 Is there a secret to make it listen correctly? TIA. Cameron

Hi all,I'm configuring a Network Access Control Solution (Packetfence ) but i have a problem to authenticate my users.I hope that someone will be able to help me.-I have a windows 2008 Active Directory for my users -I'm using a cisco 2950 switch to authenticate my users but when connecting a host i get this error on my switch,It seems like the switch cannot reach the server but i'm sure that the radius server ip address is 192.168.10.1 : RADIUS: Retransmit id 4 00:28:11: RADIUS: Retransmit id 4 00:28:13: RADIUS: Retransmit id 4 00:28:15: RADIUS: Marking server 192.168.10.1:1812,1813 dead 00:28:15: RADIUS: Tried all servers. 00:28:15: RADIUS: No valid server found.
