About definition of conflicting condition
by Yuka K 21 Apr '17

21 Apr '17

Hello. During fast-requesting tests on ver.3.0.13, I found the following errors in the log. Sun Apr 16 15:04:36 2017 : Error: Received conflicting packet from client localhost port 30430 - ID: 0 due to unfinished request. Giving up on old request. All IDs were used and it returned to 0. Both of the ID-0 packets were valid and had the same src/dst ip/port and length, but the request authenticators and AVP(User-Name) were different. So, please let me ask two questions about it. [Q1] I thought Access-Accept was returned, but like this case, even if AVPs are different and valid, the new one is regarded as a conflicting one. Then, if the previous request's process is under QUEUED or RUNNING, it's dropped. I've read RFC 5080 about "duplicate", but I want to know the definition of a "conflicting" packet based on RFCs, as the following is mentioned in RFC 2865. 3.1. Packet Format The RADIUS server can detect a duplicate request if it has the same client source IP address and source UDP port and Identifier within a short span of time. 4.1. Access-Request Upon receipt of an Access-Request from a valid client, an appropriate reply MUST be transmitted. I was wondering if checking AVPs at least User-Name might not be bad, or should I think conflict is included in duplication? [Q2] If I try to skip the duplicate/conflict check, is it OK that setting the member "nodup" of struct rad_listen to true? I'd appreciate it.

freeradius 3.0.13 refusing to start with Heartbleed-unaffected OpenSSL version

Hi, having trouble getting radiusd to work because of openssl: CLI debugging: root@$HOSTNAME:/etc/raddb# openssl version OpenSSL *1.0.2k* 26 Jan 2017 root@$HOSTNAME:/etc/raddb# cat radiusd.conf | grep allow_vulnerable # allow_vulnerable_openssl: Allow the server to start with * allow_vulnerable_openssl = yes* root@$HOSTNAME:/etc/raddb# hostnamectl Static hostname: $HOSTNAME Icon name: computer-vm Chassis: vm Machine ID: $CENSORED Boot ID: $CENSORED Virtualization: vmware Operating System: Debian GNU/Linux 8 (jessie) Kernel: Linux 3.16.0-4-amd64 Architecture: x86-64 root@$HOSTNAME:/etc/raddb# radiusd -X FreeRADIUS Version 3.0.13 [snip] Debugger not attached Refusing to start with libssl version OpenSSL 1.0.1t 3 May 2016 0x1000114f (1.0.1t release) (in range 1.0.1 release - 1.0.1t rele) Security advisory CVE-2016-6304 (OCSP status request extension) For more information see https://www.openssl.org/news/secadv/20160922.txt Once you have verified libssl has been correctly patched, set security.allow_vulnerable_openssl = 'CVE-2016-6304' The same error message when entering allow_vulnerable_openssl = 'CVE-2016-6304' in radiusd.conf No matter what I search for - every search results in something similar than https://lalitvc.wordpress.com/2014/06/26/freeradius-refusing-to-start-with-… Do I have to recompile FreeRADIUS after a new installation of OpenSSL?

Migrating freeradius install
by Dagan McGregor 21 Apr '17

21 Apr '17

Hello, I have been tasked to move a freeradius install from an old RHEL server onto CentOS 7. In the process I am looking to move the data out of a mysql database (used for dialadmin) to using static files. We are trying to keep the new configuration changes as minimal as possible for maintenance reasons. And the virtual server files look like what we need. Our site is only maintaining a small number of users with static IP addresses. A few questions... Can I pull in an external user file with an 'include' statement in a virtual server file? Via a User section? If so, if I put the server file into 'sites-enabled', do I also put the custom users file there, or should it be somewhere else? Cheers, Dagan McGregor

VLAN Post Auth
by Richard Laing 20 Apr '17

20 Apr '17

Hi there I am looking for help with setting up post authentication VLAN's with LDAP groups enabled, at present I have made a test environment and I attempting to have the groups from the LDAP server act as the determine factor in which VLAN is assigned. I have the connection to the LDAP server working and I can look up users inside the schema and them authenticated correctly at present, however once I try to place multiple VLAN's into the users file I am unable to have the post auth work, please note I while the name has Skype in the title there are no MS products involved just reusing my pfsense lab box that was setup for a previous test with Skype, also the LDAP server is current version of FreeIPA in the CentOS repos. If you require any more information please let me know and I will respond appropriately, thank you for your time. /etc/raddb/users DEFAULT Ldap-Group ==

How to have Freeradius handling multiple appliations
by Kenroy 19 Apr '17

19 Apr '17

Hi everyone, I have an access gateway that is being used by multiple applications. each application handles traffic for different VLAN (NAS-PortID). I was thinking of creating a policy for each application and filter requests for the different VLANs they handle . Then have the policy make a request to the web service for the application to get the AVP for each request coming in . Is this the best way to handle this or is using the python or Perl modules the better way ? Kenroy

SIP2 module?
by Aaron Dalla-Longa 19 Apr '17

19 Apr '17

We currently are using a server system from a vendor that supports SIP2 authentication and sockets for many different things. I am hearing back from them that LDAP may not be possible for authenticating against our users. Does freeradius support authentication vs a SIP2 socket? -- *Aaron Dalla-Longa* Systems Administrator Shortgrass Library System tf: 1.866.529.0550 | p: 403.529.0550

Force the client to use one specific EAP method
by LUCA 19 Apr '17

19 Apr '17

As Matthew suggested, I've removed the configurations for the others EAP methods, indeed now they don't work anymore. But, as Matthew already said, the clients will always choose whatever method they want to use or in the most cases the chosen method is the one set on the supplicant configuration file. I thought of making a script that would change the 802.1x configuration of the supplicant, but then every client should download and run the script, which is no practical at all. So, any other workaround that you're aware of? I was wondering if adding a realm could help somehow. Luca

Line indentation using tabs?
by Dagan McGregor 19 Apr '17

19 Apr '17

Hi, The comments in the 'users' file mentions lines should be indented with a tab when providing options below a user name. Do all the files require configuration lines to use tabs? Or is does it only matter for user entries? Are lines ignored if they are not indented with a tab? I notice most of the configuration files use hard tabs but I am not sure if this is convenient or enforced. Our coding setup uses spaces to replace tabs, so I need to make sure my deployed files are formatting correctly. Cheers, Dagan McGregor

multiple instances of pam module
by Lars Hillebrand 18 Apr '17

18 Apr '17

Hello everybody, Is there a way to include multiple instances of the pam module in the radius? We are currently using a freeradius 2.2.8 with several virtual servers. Two services are to be secured by a 2-factor authentication (Google Authenticator). 1. Login VMware HorizonView (desktop-virtualization) 2. IPsec VPN connection VMware Horizon expects a login with username and passcode with a subsequent query of the password. For the login of the VPN connection the password + passcode is expected together in a field. Attempts to integrate several instances (similar to the file or ldap module) within the pam module do not work. I am thankful for every hint. Thanks in advance.
