Joining Active Directory Domain
by Gilmour, Scott 31 Jan '12

31 Jan '12

Hi, I am following the FreeRadius Beginners Guide book on how to join a domain. I keep on getting this error when running the command. root@FreeRadius:/etc# net ads join -U Administrator Enter Administrator's password: Using short domain name -- SQA Joined 'FREERADIUS' to realm 'SQA.net' [2012/01/31 10:21:29, 0] libads/kerberos.c:333(ads_kinit_password) kerberos_kinit_password FREERADIUS$(a)SQA.NET failed: Clock skew too great No DNS domain configured for freeradius. Unable to perform DNS Update. DNS update failed! root@FreeRadius:/etc# I have checked the clock, added the dns forward lookup zone to the AD Doman. Add the AD Server to the resolv.conf and etc/hosts files. I am able to ping both servers. I am attempting to join my FreeRadius domain to my 2008 Server Active Directory Domain. Thanks Scott

Segmentation Fault in 2.1.12 - rlm_eap-2.1.12.so
by DaveA 31 Jan '12

31 Jan '12

FreeRadius has been stable for about a month, up until yesterday, and I have not changed the configuration of the server. I began seeing segmentation faults as seen below: #grep radiusd /var/log/messages Jan 30 15:53:03 radius1 kernel: radiusd[14764]: segfault at 70 ip 00007fb9d4ba81ed sp 00007fb9917fa490 error 4 in rlm_eap-2.1.12.so[7fb9d4ba6000+7000] Jan 31 09:09:43 radius1 kernel: radiusd[26073]: segfault at 70 ip 00007fe5e2c9a1ed sp 00007fe5a2bfc490 error 4 in rlm_eap-2.1.12.so[7fe5e2c98000+7000] Jan 31 09:12:33 radius1 kernel: radiusd[8743]: segfault at 70 ip 00007fa6d3acc1ed sp 00007fa6cd241490 error 4 in rlm_eap-2.1.12.so[7fa6d3aca000+7000] Jan 31 09:20:38 radius1 kernel: radiusd[9849]: segfault at 70 ip 00007ff092a6c1ed sp 00007ff08fde7490 error 4 in rlm_eap-2.1.12.so[7ff092a6a000+7000] I have not included my radiusd -X because it will need to be heavily censored and I have my fingers crossed that someone can help with only the information I've provided.

Using different realm in the same server

Hi all, I'm trying to use different realm into the same server, but I probably miss something.

Setting Acct-Interim-Interval for all users
by Nataniel Klug 31 Jan '12

31 Jan '12

Hello all, I recently went through a problem concerning Acct-Interim-Interval that, for some reason, was not been set for some of my clients. The result was catastrophic inside my network. Hopefully and been helped by Fajar A. Nugraha (which I thank for the time spent) I was able to identify the problem but I am not been able to solve the problem for good. Sometimes my Freeradius send information about a client from radgroupreply and sometimes, for the same client, it send from radreply. The problem is in this trick when it send from radreply it was not sending Acct-Interim-Interval because it was not there. I am changing my software (not freeradius) to update my SQL tables correctly but, to solve this problem, I wish I could set a DEFAULT value for Acct-Interim-Update that would work as a backup plan in cases like this. Is it possible to setup this parameter as a default for all clients using my Radius? -- Regards, Nataniel Klug

Question about WARNING in rlm_sql_mysql
by Krzysztof Grobelak 31 Jan '12

31 Jan '12

Hello all, Can somebody shed some light what the 'You probably need to lower "min"' means. I just installed fresh freeradius from git. All my settings are the same as in the last version but apart from the radiusd -X not working (but the radiusd -lxx -l stdout is) radius.log displays this warning about lowering number of sql connections. Can anybody give some advice?? Regards, Krzysztof

Mixed Environment Question
by Paul Stewart 31 Jan '12

31 Jan '12

Hi there. Thank you to those folks to helped me recently understanding the Juniper attributes etc - much appreciated. What is the practical issues with a users file entry that is mixing vendor attributes? Ie. pstewart-stat Auth-Type = System Service-Type = Framed, Framed-Protocol = PPP, Framed-IP-Address = xxx.xxx.xxx.73, Cisco-AVPair = "lcp:interface-config#2=rate-limit output 512000 375000 512000 conform-action transmit exceed-action drop", Cisco-AVPair = "lcp:interface-config#1=rate-limit input 512000 375000 512000 conform-action transmit exceed-action drop", ERX-Ingress-Policy-Name = lite, ERX-Egress-Policy-Name = lite So far I have tested this on a Juniper ERX and it simply ignores the Cisco attributes, which was what I'm hoping for. I plan to float some Juniper attributes towards some Cisco gear at some point to see how it handles it. Anyone have much practical experience with this? Is it expected to always ignore additional VSA's or is it a 'crap shoot' depending on the vendor? We have customers that sometimes will connect to Cisco for example, but could also connect that same username to a Juniper (not at the same time, but within minutes of one another). I am trying to come up with a users file entry that keeps all vendor specific attributes in intact - am I playing with fire? ;) Paul

Decoding complex CableLabs-Event-Message
by Laurent Debacker 31 Jan '12

31 Jan '12

Hi, We would like to use FreeRadius to decode Cablelabs accounting messages, as specified in http://www.cablelabs.com/packetcable/downloads/specs/PKT-SP-EM-I12-05812.pdf . FreeRadius has a CableLabs dictionary, which works fine, but... The value of one of the AVP, CableLabs-Event-Message, is actually an HEX value containing additional fields. For example: CableLabs-Event-Message = 0x0001d2d2026d30310000000000003030313030303000 0e812333000100033031000000000000303031303030300000000006323031323031333130363032 32312e3633390000000081000500 The FreeRadius does not decode that value to get all details. For example, bytes 4 to 28 (d2d2026d303100000000000030303130303030000e812333) is actually the BCID (Billing Correlation ID) field. The BCID itself contains 4 "sub" fields: NTP time reference (4 first bytes), Element ID (next 8 bytes), Time Zone (next 8 bytes), and Event counter (ast 4 bytes). See the packet cable specifications for more details. I understood the only way would be to write a perl module to decode those values. Before I start writing, does anyone know of any implementation of such a perl module? I would not like spending my time rewriting something that already exists. Thanks in advance for any help anyone could provide on this topic. Laurent.

How to Restrict All Users from Certain APs
by White III, Joe 31 Jan '12

31 Jan '12

I'm running Freeradius 1.0.1 using MySQL as the database backend. I need to configure the server so that all users are restricted from using certain access points (i.e. guest network). It appears I need to use a DEFAULT user definition in the users file, but I can't find any examples to work from. Has someone else done this? If so, I'd give anything to see how you did it. Thanks.

Problems using SQL IP Pool
by Nataniel Klug 30 Jan '12

30 Jan '12

Hello all, Ive been using Freeradius for a long time and about 5 months ago I made a change in my default layout so I could use Freeradius SQL-IPPool running over PostgreSQL. This is working almost fine but for some reason I cant figure out its giving the same IP address to two different clients. So, my network layout is something like this: [ freeradius ] -- [ external* mysql ] -- [ external* postgresql ] * external I mean as the databases are running in separate hardware but in the same physical network My customers are authenticating over PPPoE interfaces on two parallel servers that work as a backup for each other but they are running simultaneously. This would be layout for my clients: (internet) [ auth01/auth02 ] (clients) Auth01 and Auth02 can both communicate with Freeradius in the same physical network and they are getting there with no more than 1 ms (its a gigabit network that fairly is using 50 mbit). I am using MySQL and PostgreSQL for a reason: somehow the software I use to bill my customers can only work with MySQL radacct table and it was not able to read the radacct from PostgreSQL. So I am running accounting over MySQL and Authentication/Authorization over PostgreSQL (I will post the configuration files in the end of this message). So, returning to the problem, this is what is happening: http://www.cnett.com.br/nata/imagens/Capturar.JPG There is two clients using the SAME IP which is a problem. Looking into my Freeradius log file I could not find when cjunior got the IP I have JUST taise allocation: Fri Jan 27 12:20:03 2012 : Auth: Login OK: [cjunior] (from client LJS.AUTH.02 port 69822 cli 74:EA:3A:D1:FD:17) Fri Jan 27 12:20:03 2012 : Info: Allocated IP: 186.251.148.216 from main_pool (did cnett_pppoe cli 74:EA:3A:D1:FD:17 port 69822 user cjunior) Fri Jan 27 14:41:38 2012 : Info: Released IP 186.251.148.216 (did cnett_pppoe cli 74:EA:3A:D1:FD:17 user cjunior) Fri Jan 27 14:45:47 2012 : Auth: Login OK: [taise] (from client LJS.AUTH.02 port 69530 cli 00:02:72:89:34:C5) Fri Jan 27 14:45:47 2012 : Info: Allocated IP: 186.251.150.130 from main_pool (did cnett_pppoe cli 00:02:72:89:34:C5 port 69530 user taise) Fri Jan 27 15:18:01 2012 : Auth: Login OK: [cjunior] (from client LJS.AUTH.02 port 69668 cli 74:EA:3A:D1:FD:17) Fri Jan 27 15:18:01 2012 : Info: Allocated IP: 186.251.150.226 from main_pool (did cnett_pppoe cli 74:EA:3A:D1:FD:17 port 69668 user cjunior) Fri Jan 27 12:19:14 2012 : Info: Allocated IP: 186.251.150.136 from main_pool (did cnett_pppoe cli 00:02:72:89:34:C5 port 69799 user taise) Fri Jan 27 23:22:04 2012 : Info: Released IP 186.251.150.130 (did cnett_pppoe cli 00:02:72:89:34:C5 user taise) Mon Jan 30 08:19:05 2012 : Info: Released IP 186.251.150.5 (did cnett_pppoe cli 00:02:72:89:34:C5 user taise) Mon Jan 30 08:20:23 2012 : Auth: Login OK: [taise] (from client LJS.AUTH.02 port 69525 cli 00:02:72:89:34:C5) Mon Jan 30 08:20:23 2012 : Info: Allocated IP: 186.251.151.65 from main_pool (did cnett_pppoe cli 00:02:72:89:34:C5 port 69525 user taise) Mon Jan 30 08:23:54 2012 : Info: Released IP 186.251.151.65 (did cnett_pppoe cli 00:02:72:89:34:C5 user taise) Mon Jan 30 08:24:05 2012 : Auth: Login OK: [taise] (from client LJS.AUTH.01 port 350112 cli 00:02:72:89:34:C5) Mon Jan 30 08:24:05 2012 : Info: Allocated IP: 186.251.150.118 from main_pool (did cnett_pppoe cli 00:02:72:89:34:C5 port 350112 user taise) This is really strange.

For those who ask I change the pool_key because I was having duplicated pool_key from my NAS (Auth01 and Auth02) so I just made a change where the name of the server is showing. The problem with the duplicate IPs is older than the change so the pool_key is discarded. http://www.cnett.com.br/nata/imagens/cpu_usage_postgres-mysql.JPG Is it possible to someone help me finding a solution? -- Descrição: Descrição: 111027-nata_at_cnett
