sending POD for PPPoe
by Randeep 16 Sep '15

16 Sep '15

Hi Alan, We have both pppoe and hotspot services. If the user reaches the max data limit we are applying fup limit by sending a coa update. But with pppoe coa is not working. So we implemented the following logic. If the user exceeded the limit, then we will check whether its pppoe or hotspot. If it is pppoe we are sending disconnect. update control { #sum of the AcctInputOctets+AcctOutputOctets for this month.(From the first day of the current month to till date) Tmp-Integer-0 := "%{sql:SELECT (SUM(acctinputoctets)+SUM(acctoutputoctets)) AS Total FROM radacct where radacct.username='%{User-Name}'}" #Value of Max-Data from the radgroupcheck for the group of the user Tmp-Integer-1 := "%{sql: SELECT radgroupcheck.value FROM radusergroup INNER JOIN radgroupcheck ON radusergroup.groupname = radgroupcheck.groupname WHERE radusergroup.username='%{User-Name}' AND radgroupcheck.attribute='Max-Data'}" Tmp-String-1 := "%{sql: SELECT radgroupcheck.value FROM radusergroup INNER JOIN radgroupcheck ON radusergroup.groupname = radgroupcheck.groupname WHERE radusergroup.username='%{User-Name}' AND radgroupcheck.attribute='Mikrotik-Rate-Limit'}" Tmp-String-3 = "%{sql:select calledstationid from radacct where acctsessionid='%{Acct-Session-Id}'}" } if ("%{control:Tmp-Integer-0}" > "%{control:Tmp-Integer-1}") { #Added these to update COA for hotspot and disconnect for PPPOE if ("%{control:Tmp-String-3}" == "hotspot1"){ update coa { User-Name = "%{User-Name}" Acct-Session-Id = "%{Acct-Session-Id}" NAS-IP-Address = "%{NAS-IP-Address}" Framed-IP-Address = "%{Framed-IP-Address}" Mikrotik-Rate-Limit = "%{control:Tmp-String-1}" } } else { echo "Acct-Session-Id=\"%{Acct-Session-Id}\"" > /tmp/\"%{User-Name}\".txt echo "User-Name=\"%{User-Name}\"" >> /tmp/\"%{User-Name}\".txt echo "NAS-IP-Address=\"%{Framed-IP-Address}\"" >> /tmp/\"%{User-Name}\".txt Secret= `grep "%{NAS-IP-Address}" /usr/local/etc/raddb/clients.conf -b2 | grep secret |awk '{print $4}' ` cat "/tmp/\"%{User-Name}\".txt" | radclient -x "%{NAS-IP-Address}":3799 disconnect "$Secret" } } But when running radiusd -XXX its giving the following error. Wed Sep 16 12:14:04 2015 : Error: /usr/local/etc/raddb/sites-enabled/default[623]: Expecting section start brace '{' after "echo Acct-Session-Id="%{Acct-Session-Id}"" Wed Sep 16 12:14:04 2015 : Error: Errors reading or parsing /usr/local/etc/raddb/radiusd.conf Please help Regards, Randeep

Whitelisting LAN
by Randeep 16 Sep '15

16 Sep '15

Hi all, We are using FreeRadius for Hotspot and PPPoE authentication in out network. But the authentication is required only when the user connects to internet. We have iptv services available in our network. This shouldnt be affected when restricting the bandwidth and applying the FUP. The problem is when the FUP is applied even the iptv services in LAN gets affected. How can we whitelist the LAN ips so that local services will not get affected by applying radius policies? Regards, Randeep

proxy/home-server, could be set dynamically?
by Jorge Pereira 15 Sep '15

15 Sep '15

Hi, The "home-server", could be set dynamically? because today I have used the below approach. # 1) list of tens and tens of homeservers that is used the ident based on NAS-Identifier home_server coa_SAME_NAS_IDENTIFIER1 { type = coa secret = hello ipaddr = 1.2.3.4 port = 3799 proto = udp revive_interval = 10 status_check = none check_interval = 10 num_answers_to_alive = 3 } home_server_pool coa_pool_SAME_NAS_IDENTIFIER1 { type = fail-over home_server = coa_SAME_NAS_IDENTIFIER1 } ..... same thing to another servers. # 2) in the recv-coa, I have recv-coa { ...... update control { &Home-Server-Pool := "coa_pool_%{NAS-Identifier}" } ...... } --------- Conclusion: I would like to know if have some way to set a values of Home-Server dynamically. -- Jorge Pereira

3.0.x: user-password length decoding sometimes wrong?
by Stefan Winter 15 Sep '15

15 Sep '15

Hi, ugh. I just updated to 3.0.x from a few minutes ago to be prepared for the MS-CHAP key problem and iOS 9. That seems to work - good. But I have a problem with good old PAP but only for requests originating from one of the clients - and consistently. That client is insanely old and has ancient library versions. So it may well be doing something subtly wrong in the requests it sends; but still, this worked for a FreeRADIUS server versions since a decade. But not in current 3.0.x. What I see coming in (decoded in -X) is: (137) Received Access-Request Id 89 from 158.64.1.50:8010 to 158.64.2.220:1812 length 80 [...] (137) User-Password = "12345678\000\000\000\000\021" That's an 8 char password (12345678 is the equivalent of correct; i.e. redacted in this mail but it otherwise fits). On other clients, the same password comes in as User-Password = "12345678" as expected; a tcpdump between for both clients reveals that the on-the-wire length of User-Password is the same (16 chars net, to account for padding). Current 3.0.x then does SSHA password comparison between what it got and the contents in our DB, and finds that the SSHA hash of the above first string does not match our stored password hash, while the second one does. So it's a Accept/Reject difference and our users are not happy. Now since padded-and-encrypted parsing differences are the exact problem that was fixed for 3.0.9, I suspect that fixing that had a side-effect on PAP password length extraction. It looks like the old client uses \0-then-something-random as padding (I also saw requests with jsut one \0 and then more garbage) while newer clients pad with \0\0\0\0 until the attribute ends. And that the latter works, while the former doesn't :-) I realise that all \0 is what RFC2865 chapter 5.2 mandates as padding text. So, yes, our client is at fault. Still, is there any chance that the server-side parsing could be made a little more forgiving?

EAP session problem
by Stefano Pardini 15 Sep '15

15 Sep '15

Hi guys, I'm using PEAP/MSCHAPV2 and OpenLDAP password backend (and Samba3) to provide wpa2-enterprise authentication to wifi users inside an high school (with OpenWRT access point). Everything has been working very well for one year. Wonderful! Three days ago something very strange has started to happen. Wifi users can't create a TLS tunel (windows, linux, android) to provide the authentication. I didn't touch the configuration files in the last few months. Nothing has changed.

Specific, complicated, detailed user rights possibility?
by Mart Pirita 14 Sep '15

14 Sep '15

Hi, We have idea to use radius for rights and ldap for authentication. So that radius acts proxy for external ldap and this part is working. But we need more detailed setup, for example, the idea is to allow user1 access some switches and disable user1 to access some other switches. And then even more specific rights, for example, switches which user1 can access, he have some switch with read-only and some other switch with read-write rights. And do it with groups, not using different configuration for every user, for example, so that users are listed in as groups, and these groups are used in access configurations? Huntgroups may be the solution, but as far I know, huntgroups are for device, and not for user rights. Also I don't know, can one and same device IP exist in many different huntgroups and can one huntgroup include other huntgroups? Is such setup possible and if yes, then how? -- Mart

Thanks Alan. Here¹s the thing.. My SP tell me I am sending the the correct details, its just that the info for the specific user that they tell me is whats causing the issue..

I do appreciate it.. Apologies for the lack of detail here is more info FreeRADIUS Version 2.1.12 I have deployed using just the local users file with x3 test accounts including the information that the provider has requested I respond with to complete the auth between our LNS and their BRAS. I had x1 connection up and stable for 3weeks. I shipped out x2 more routers and I start to see some strange behaviour. FR authenticates the session fine but on the router console the interface is reset straight away and so the loop of authentication continues. Running FR in debug/verbose I can see the sessions being authenticated as I would expect with all of the relevant user attributes being passed. The below is what the SP has requested I return to their BRAS; mydom.net.uk Cleartext-Password := ³password" Service-Type = Outbound-User, Tunnel-Type = L2TP, Tunnel-Medium-Type = IP, Tunnel-Password = password, Tunnel-Server-Endpoint = 89.x.y.134, Tunnel-Client-Auth-ID = ³MY-LNS" The following is an example of a user account and the Cisco AVP that I am sending; test(a)mydom.net.uk Cleartext-Password := ³test" Service-Type = Framed-User, Framed-Protocol = PPP, Framed-MTU = 1440, Framed-IP-Address = 10.31.253.253, Framed-IP-Netmask = 255.255.255.255, Framed-Route = "0.0.0.0 0.0.0.0 89.x.y.134", Cisco-AVPair = "ip:vrf-id=VRF_417858", Cisco-Avpair += "ip:route#1=vrf VRF_417858 10.31.249.0 255.255.255.0 10.31.253.253 tag 417858", Cisco-AVPair += "ip:ip-unnumbered=Loopback417858" The SP is advising me that from their debugs I am sending them everything after the username & password as listed above.. They mention that I should have 2 instances for RADIUS or that I change the radius system I use..

https Radius authentication problem
by Timmy 13 Sep '15

13 Sep '15

Dear All Radius Developers, I am doing a web Radius authentication. I am also reading Mr. Alan DeKok's article about its security issue. https://github.com/FreeRADIUS/mod_auth_radius For http connection to the website, we know that the password is not encrypted. Now I set up a SSL certificate for the website in question. How do you rate the security of this https Radius authentication? Is the password, being sent over the internet, also encrypted by the usual SSL layer? Hope to receive your helpful response. Yours Faithfully, Timmy
