sending requests to a virtual server when behind a proxy
by Louis Munro 15 Jul '15

15 Jul '15

Hello, I have a set of servers behind two FreeRADIUS servers configured to proxy and load balance to a pool of backend FR servers (2.26 both on the load balancers and backend). I would like to send some requests to a different virtual server on the backend to authenticate our VPN requests separately from the regular Wireless authentications. I can set the virtual server in the client definition (on the backend servers) and that seems to work well but when the requests are proxied through the load-balancers the client is the proxying server and so my virtual server config is not applied. I could alway send those requests to a virtual server listening on a different port on the backend, but I would like to avoid that if there is a way. That just adds more complexity and ports to manage in firewall and such. Am I missing something obvious? I don’t think this could be done using dynamic clients since I can’t inspect the NAS-IP-Address there. Any other way that someone can think of?

MySQL Authentication Problem (v3.0.3)
by Pyromancer 15 Jul '15

15 Jul '15

I am attempting to build a replacement radius server for a client who's primary v2.0.2 machine has gone down for good. There is a secondary so service continues for now. The old system had a very complex config which hands off lots of realms to LNSs and also does authentication for non-handed-off users via MySQL. Initially I attempted to replicate the original server on a newly installed machine, however FR 2.0.2 refused to compile with MySQL on the new box (Current SuSE, vendor MySQL). So I've installed the vendor FreeRadius (3.0.3 64bit). Initially I tried using the existing config copied from the secondary box, after commenting out all the depreciated attributes it ran and talked to MySQL however refused to authenticate a test user. Research led to the Wiki and mailing list, comments re changing the default config as little as possible (and potentially greater b0rkake the more this is ignored noted), So having backed up the original config I cleared it and am starting from scratch with the default one, and slowly adding in the features of the client's original system. This has the side benefit of removing a lot of redundant stuff from the files. However it's refusing to authenticate the MySQL users, giving a no known good password error, even though the cleartext password is present in the database and matches what radtest is submitting. The output from radiusd -X is below - the obvious problem is the "(0) WARNING: pap : No "known good" password found for the user. Not setting Auth-Type." line. But look above that and the user is found in the radcheck table - there are no group entries as this is a purely local auth-only user. This user was able to authenticate from radtest on the old server (and still is on the secondary), the databases are identical. I know there's another error further down regarding the accounting due to a missing table, but as that's after the auth section I'm assuming that won't be related to why a reject is being generated. I've tried running -X -x and -xx to get more detailed debug, but it doesn't reveal any more information on why the reject is being generated. The database entry looks like this: mysql> SELECT id, username, attribute, value, op FROM radcheck WHERE username = 'xktester' ORDER BY id; +------+------------+----------------------+------------------------------+----+ | id | username | attribute | value | op | +------+------------+----------------------+------------------------------+----+ | 3983 | xktester | Cleartext-Password | correct_horse_battery_staple | == | +------+------------+----------------------+------------------------------+----+ 1 row in set (0.00 sec) radiusd -X output: Received Access-Request Id 228 from 127.0.0.1:60330 to 127.0.0.1:21812 length 76 User-Name = 'xktester' User-Password = 'correct_horse_battery_staple' NAS-IP-Address = 192.168.142.85 NAS-Port = 10 Message-Authenticator = 0x48c52fb5b7f81584a37eccc1eb44a643 (0) # Executing section authorize from file /etc/raddb_ADSL//sites-enabled/default (0) authorize { (0) filter_username filter_username { (0) if (User-Name != "%{tolower:%{User-Name}}") (0) EXPAND %{tolower:%{User-Name}} (0) --> xktester (0) if (User-Name != "%{tolower:%{User-Name}}") -> FALSE (0) if (User-Name =~ / /) (0) if (User-Name =~ / /) -> FALSE (0) if (User-Name =~ /@.*@/ ) (0) if (User-Name =~ /@.*@/ ) -> FALSE (0) if (User-Name =~ /\\.\\./ ) (0) if (User-Name =~ /\\.\\./ ) -> FALSE (0) if ((User-Name =~ /@/) && (User-Name !~ /(a)(.+)\\.(.+)$/)) (0) if ((User-Name =~ /@/) && (User-Name !~ /(a)(.+)\\.(.+)$/)) -> FALSE (0) if (User-Name =~ /\\.$/) (0) if (User-Name =~ /\\.$/) -> FALSE (0) if (User-Name =~ /(a)\\./) (0) if (User-Name =~ /(a)\\./) -> FALSE (0) } # filter_username filter_username = notfound (0) [preprocess] = ok (0) [chap] = noop (0) [mschap] = noop (0) [digest] = noop (0) suffix : No '@' in User-Name = "xktester", looking up realm NULL (0) suffix : No such realm "NULL" (0) [suffix] = noop (0) eap : No EAP-Message, not doing EAP (0) [eap] = noop (0) [files] = noop (0) sql : EXPAND %{User-Name} (0) sql : --> xktester (0) sql : SQL-User-Name set to 'xktester' rlm_sql (sql): Reserved connection (4) (0) sql : EXPAND SELECT id, username, attribute, value, op FROM radcheck WHERE username = '%{SQL-User-Name}' ORDER BY id (0) sql : --> SELECT id, username, attribute, value, op FROM radcheck WHERE username = 'xktester' ORDER BY id rlm_sql (sql): Executing query: 'SELECT id, username, attribute, value, op FROM radcheck WHERE username = 'xktester' ORDER BY id' (0) sql : User found in radcheck table (0) sql : EXPAND # SELECT groupname # FROM radusergroup # WHERE username = BINARY '%{SQL-User-Name}' # ORDER BY priority (0) sql : --> # SELECT groupname # FROM radusergroup # WHERE username = BINARY 'xktester' # ORDER BY priority rlm_sql (sql): Executing query: '# SELECT groupname # FROM radusergroup # WHERE username = BINARY 'xktester' # ORDER BY priority' rlm_sql_mysql: MYSQL Error: No Fields rlm_sql_mysql: MYSQL error: (0) sql : User not found in any groups rlm_sql (sql): Released connection (4) (0) [sql] = noop (0) [expiration] = noop (0) [logintime] = noop (0) WARNING: pap : No "known good" password found for the user.

freeradius-3.0 problem with EAP-TTLS
by Till Dörges 15 Jul '15

15 Jul '15

[Not sure where to report this. So please advise, if there's a more suitable place.] Dear all, When upgrading our running freeradius-2.2 configuration for EAP-TTLS to freeradius-3.0 we followed the guide from http://freeradius.org/version3.html and almost everything was running in our test environment except one point already discussed similarly: http://lists.freeradius.org/pipermail/freeradius-users/2015-March/076365.ht… We had the same problem with our wpa_supplicant and Oddyssey clients: The very last ACK from the client was not well recognized by freeradius-3 with the same DEBUG message, also see (partly obfuscated radius.debug.txt): Login incorrect (eap_ttls: Invalid ACK received: 0) Encouraged from the thread follow-up http://lists.freeradius.org/pipermail/freeradius-users/2015-May/077614.html we checked the values returned to the method tls_ack_handler() in src/main/tls.c : In fact we found for the last ACK: ssn->info.content_type == 0 (instead of handshake == 22) ssn->info.handshake_type == handshake_finished (expected 20) ssn->dirty_out.used == 0 In order to make it work, we patched freeradius-3 like this (also see attachments tls.c.patch and tls.c.original): $ diff tls.c.patch tls.c.original 3130,3134d3129 < /* patch needed for many versions of TTLS clients, compare http://lists.freeradius.org/pipermail/freeradius-users/2015-May/077614.html */ < if ((ssn->info.handshake_type == handshake_finished) && (ssn->dirty_out.used == 0)) { < ssn->info.content_type = handshake; < } < HTH -- Till -- Dipl.-Inform.

rlm_files: Collided users not always sorted
by Dylan Jones 14 Jul '15

14 Jul '15

I believe I have found a bug in that when I have a lot of users with similar enough naming that results in hash collisions, the collided users in the linked list are not always properly sorted. This results in a noop from the rlm_files module and authentication failure. I have tested 2.1.7 and a 3.1 pull from git. Since I'm unable to paste such a large users file, hopefully this TCL snippet, which you can redirect to a file, will suffice to generate the users file. #! /usr/bin/env tclsh set users [list] set pw "thisisatest" for {set i 8} {$i < 16} {incr i} { for {set j 0} {$j < 32768} {incr j} { lappend users "[format %016d [expr {$j + 1}]](a)aaaaa${i}.com\tCleartext-Password := \"$pw\"" } } puts [join $users "\n"] In this file, there will be 6 users that cannot be authenticated and it always seems to happen in pairs. Mon Jul 13 12:17:40 2015 : Auth: (0) Login incorrect (No Auth-Type found: rejecting the user via Post-Auth-Type = Reject): [ 0000000000026311(a)aaaaa10.com/thisisatest] (from client name port 0) Mon Jul 13 12:17:49 2015 : Auth: (1) Login incorrect (No Auth-Type found: rejecting the user via Post-Auth-Type = Reject): [ 0000000000026311(a)aaaaa11.com/thisisatest] (from client name port 0) Mon Jul 13 12:17:53 2015 : Auth: (2) Login incorrect (No Auth-Type found: rejecting the user via Post-Auth-Type = Reject): [ 0000000000028649(a)aaaaa12.com/thisisatest] (from client name port 0) Mon Jul 13 12:17:57 2015 : Auth: (3) Login incorrect (No Auth-Type found: rejecting the user via Post-Auth-Type = Reject): [ 0000000000028649(a)aaaaa13.com/thisisatest] (from client name port 0) Mon Jul 13 12:18:00 2015 : Auth: (4) Login incorrect (No Auth-Type found: rejecting the user via Post-Auth-Type = Reject): [ 0000000000028471(a)aaaaa14.com/thisisatest] (from client name port 0) Mon Jul 13 12:18:05 2015 : Auth: (5) Login incorrect (No Auth-Type found: rejecting the user via Post-Auth-Type = Reject): [ 0000000000028471(a)aaaaa15.com/thisisatest] (from client name port 0) I have debugged this to the point where if I relax the 'if (cmp > 0) break;' in list_find to 'if (cmp > 0) continue;', forcing a further walk of the list, my users will be authenticated. At this point though, the reverse split-ordered list is a bit beyond me and I'm looking for some help. Any ideas? Is this enough for a defect? Thanks, Dylan

Copy-acct-to-home-server Issue
by Ricardo Larrañaga 14 Jul '15

14 Jul '15

Hello Guys, i was wondering if you could give me some pointers on how to troubleshoot an issue. I am running freeradius 3.0.4 on Centos 7, and i am using copy-acct-to-home-server in order to replicate the accounting database between the 3 servers. Right now, all my NAS are only pointing to one server (Lets call it server1). So server2 and server3 do not receive authentication requests, they just receive accounting packets from server1. Now, with some NAS i also see issues where i miss accounting stop packets, and i end up with stale sessions. I am working on solving that, but in the mean time i run a script on all three servers that queries all NAS for active sessions and marks the stale sessions as Terminated. My script logs the stale sessions, so i can compare them between servers. My problem is that the stale sessions between the servers are different. Usually, server 2 and 3 have more stale sessions than server 1. This would tell me that there are accounting packets not processed or missing between server 1 and server 2 and 3. First thing i did was looking at the networking side of things. All interfaces between the servers run clean, they are all connected to the same switch. So i am trying to troubleshoot what is happeing with these packets. The questions i have are: 1) My copy acct-to-home-server for each server configuration is as follows: - log all the incoming packets to a detail file. -copy-acct-to-home-server server reads the detail file and updates the proxy-to-realm control attribute so the packet gets proxied to the other server. Acct always returns ok. If i understand this correctly, in this configuration the packets are "Sent and forgotten". So if a packet fails to be received or processed by server2 or server3, it wont be retried. The fact that all the detail files are empty makes me think that this is the way the server is working right now. Any ideas on how could i implement a simple "retry 3 times" policy? My issue is that since i proxy the packet, and and always return ok on accounting, i am not sure where to put the "IF packet failed to ACK, return fail". From what i see, it cannot be done in the proxy section, unless i do something like: realm SERVER1 { } 2) I dont see anything in the logs that would indicate there is a problem with packets being sent to the other to servers. How can i catch these issues from the logs or debug perspective? the only thing i can think of is to turn debug on for all the packets with packet-source-destination equals "server 2" and server 3" in server one, and go from there, but any suggestions would be appreciated, as that would basically be my whole radius acct traffic. I am copying here the contents of copy-acct-to-home-server, for reference (They are identical for all servers): server copy-acct-to-SERVER2 { listen { type = detail filename = /buffer_disk/SERVER2/detail_SERVER2 load_factor = 10 } preacct { update control { Proxy-To-Realm := "SERVER2" } } accounting { ok } pre-proxy { } post-proxy { } } My proxy.conf section only contains a realm section from it server, in the old configuration fashion (I probably should change it to the new one): realm "SERVER1" { nostrip authhost = 192.168.1.1:1812 accthost = 192.168.1.1:1813 secret=itssecret } As always, thank you very much for your help!. Regards

Currently, I am doing: Mon Jul 13 19:06:23 2015 : Debug: (5) if (!&Called-Station-Id || &Called-Station-Id == "" || &Called-Station-Id == "00:00:00:00:00:00") { Mon Jul 13 19:06:23 2015 : Debug: (5) if (&ADSL-Agent-Circuit-Id) { Mon Jul 13 19:06:23 2015 : Debug: (5) if (&ADSL-Agent-Circuit-Id) -> TRUE Mon Jul 13 19:06:23 2015 : Debug: (5) if (&ADSL-Agent-Circuit-Id) { Mon Jul 13 19:06:23 2015 : Debug: (5) update { Mon Jul 13 19:06:23 2015 : Debug: (5) EXPAND %{string:&ADSL-Agent-Circuit-Id} Mon Jul 13 19:06:23 2015 : Debug: (5) --> ca:fe:ca:fe:00:01\000JORGE-SSID\000ok Mon Jul 13 19:06:23 2015 : Debug: (5) *&request:Called-Station-Id := ca:fe:ca:fe:00:01* Mon Jul 13 19:06:23 2015 : Debug: (5) } # update = noop Mon Jul 13 19:06:23 2015 : Debug: (5) } # if (&ADSL-Agent-Circuit-Id) = noop Any suggestion will be great. -- Jorge Pereira
