radippool and expiry time
by Mirko Alberio 27 Aug '21

27 Aug '21

Hi! We have this "issue": - Our NAS are correctly configured with 10 minutes Interim-Update - Radius has 1h lease time for radippool module all is working fine but when simulating a NAS outage, for example it becomes disconnected from our network, IPs allocated from PPPOE users on that nas remain allocated even if expiry time is expired. Then when NAS comes back the expiry time is updated and all works fine, but our doubt is if this behaviour is intended or there is some other configuration our side: I expect that if an allocation expires because no interim update is received (and no accounting-stop is received because the NAS is not communicating) allocation should be freed, right?

Configurations for proxying radius requests to home-server using TCP
by Abhilash Y G 26 Aug '21

26 Aug '21

Proxying to homeserver using a TCP connection is causing issue. I am seeing the response from the homeserver, it seems like freeradius running on proxy server is not honoring the response. I have attached the debug logs collected on the proxying server (debug_proxy_server.txt), homeservers (debug_homeserver.txt). I had to trim the logs to focus on issue logs due to limitation in sending attachments more than 500KB. Please advise if any configuration changes are needed on the proxying server to handle the requests without timeouts. Please note, all the homeservers are running freeradius. Regards, Abhilash

Override/set Current-Time for rlm_logintime testing
by Jason Healy 26 Aug '21

26 Aug '21

I'm working on using rlm_logintime to enforce time of day logins for certain users. I'm also building some radclient packets that I can use to test different time boundaries to make sure my policies are correct. However, logintime looks like it's always using the packet arrival time to do its calculations (understandably; there's no other reliable source). Is there any way to override the packet arrival time, through an attribute or function? I tried setting Packet-Original-Timestamp with no luck. I also tried setting Current-Time, but that looks like a kind of virtual attribute that can be checked (against simple time strings), but not printed or assigned directly. Thanks for any clarification, Jason

attr_nas_filter_rule for VSA Alc-Nas-Filter-Rule-Shared
by Jan 'yanek' Bortl 25 Aug '21

25 Aug '21

Hello, we just discovered that latest version of Freeradius has support [1] for RFC4849 like mangling attribute NAS-Filter-Rule. We woud like enable this mangling also for VSA attribute Alc-Nas-Filter-Rule-Shared [2]. Is that somehow possible?

802.1X - ntlm, Secure LDAP and dynamic vlan
by Ray Burquest 25 Aug '21

25 Aug '21

Hi, I am setting up a pilot for 802.1X with dynamic VLAN assignment based on the domain of the user attempting to connect to the switch. Users will be authenticated through different means depending on their domain ie user(a)domainA.com<mailto:user@domainA.com> = ntlm user(a)domainB.com<mailto:user@domainB.com> = Secure LDAP unrecognised domain = default guest VLAN I have got ntlm authentication and Secure LDAP authentication working independently but I would like some guidance as to how and where I configure the selection process and then then how to return the VLAN information Thanks Ray Burquest Consultant Respiro Pty Ltd m: +61 466 557 149 e: rburquest(a)respiro.com.au<mailto:rburquest@respiro.com.au>

Config Issue
by Adam Taylor 23 Aug '21

23 Aug '21

Hey All, I have gone around and around with our FreeRadius server and I am at a lost for what is going on. The server at some point is replacing the username(a)ulm.edu<mailto:username@ulm.edu> (or username(a)warhawks.ulm.edu<mailto:username@warhawks.ulm.edu>) with anonymous(a)ulm.edu<mailto:anonymous@ulm.edu> and saying "Login Ok" Here is the thing....it's not doing this for every account...it seems to be random. Here is the logs I see when it does it: Aug 23 16:08:11 ulm-radius1 radiusd[17337]: (8062025) Login OK: [laurencenr(a)warhawks.ulm.edu] (from client wireless port 500 cli F0-1D-BC-AB-35-67 via TLS tunnel) Aug 23 16:08:11 ulm-radius1 radiusd[17337]: (8062025) Login OK: [anonymous(a)warhawks.ulm.edu] (from client wireless port 500 cli F0-1D-BC-AB-35-67) I can't seem to find where\when it is substituting anonymous in. Here is when someone else connects to the same SSID(uses same site config on radius): Aug 23 18:46:45 ulm-radius1 radiusd[17337]: (8897019) Login OK: [vuvd(a)warhawks.ulm.edu] (from client wireless port 256 cli 30-4B-07-5C-D9-7A via TLS tunnel) Aug 23 18:46:45 ulm-radius1 radiusd[17337]: (8897020) Login OK: [vuvd(a)warhawks.ulm.edu] (from client wireless port 256 cli 30-4B-07-5C-D9-7A) So what in the world is happening and where is anonymous slipping in from? Since the last login is "Anonymous"...that's what the WiFi controller shows as a user name. I can run debug and output that to you but that file gets HUGE very quickly as the server is production and quite busy. Was hoping someone would know at least where I could look. It's something with the inner/outer tunnels I think...I'm just not sure what/where or why. Thanks, Adam Taylor

VRF config from v2 to v3
by Richard Mealing 23 Aug '21

23 Aug '21

Hi there, A long time ago someone set up a freeradius server within our company and used the following patch places in policy.txt for vrf users - http://lists.freeradius.org/pipermail/freeradius-devel/2005-November/000699… After searching around I am not sure google has any answers for me for a v3 version. I wondered if anyone has the unlang config for this? Thanks, Rich

Proxy PAP authentication and encapsulate it as EAP-TTLS
by Idan Sheinberg 22 Aug '21

22 Aug '21

Hi We are trying to integrate with JumpCloud's RADIUS services in to order to provide MFA/2FA integration for OpenVPN services Our RADIUS client is a PfSense appliance on AWS that doesn't support EAP-TTLS. Due to the need to support OTP, we are limited to the PAP protocol What we're interested in doing is setting an intermediary FreeRadius proxy in between, that'll accept PAP authentication request from our local appliance and proxy them to the remote endpoint encapsulated in EAP-TTLS requests (we have the remote endpoint server certificate): +----------------------+ +----------------------+ +-----------------------------+ | | | | | | | PfSense VPN | PAP | FreeRADIUS | EAP-TTLS/PAP | JumpCloud RADIUS | | +----------------> +-------------------------> | | Appliance | | Proxy | | Server | | | | | | | +----------------------+ +----------------------+ +-----------------------------+ I've successfully got standard PAP proxying working, but I have no clue as to how to get EAP-TTLS encapsulation working 1) Is such proxying setup even possible? 2) If so, could anyone please provide me with some general guidelines as to how to get such setup working? 10x -- Best Regards Idan Sheinberg Professional Coder
