Perl vs. python vs. Lua?
by Dom Latter 12 Apr '18

12 Apr '18

Hi, we have been using the exec module with version 2 to run an external PHP script that (for example) assigns a VLAN depending on the user's location [1] - this is done post-auth. We have migrated to freeradius version 3. I note from http://networkradius.com/doc/3.0.10/raddb/mods-available/exec.html that "The exec module may look like it works for one or two tests, but in a live situation it can cause the server to become unresponsive under load. The perl module is recommended for general-purpose computing." Now if I had read that four years ago I'd not have gone down the exec route... anyway. So it seems to me we need to rewrite the exec module using one of the scripting modules. So I am wondering how the python module compares to the perl module. I found and read a great post from Herwin Weststrate <herwin(a)quarantainenet.nl> from November 2016 that explains some of the differences. I'd rather use python than perl, all else being equal. Lua is an outlier of an option. Any thoughts? Apologies if any of the above is unclear. [] which we get from the access-point identifier string.

FreeRadius Server crashed when creating a large number of ipsec gateway tunnels.
by Li Guanqun 12 Apr '18

12 Apr '18

Hi expert, I am trying to create about 260 ipsec gateway tunnels in my femto test environment with FreeRadius(ver.2.2.0) installed. I prerared 1k users on both Femto and FreeRadius server(as "ipsec.db" and "users" file). However, freeRadius Server crashed during creating the 78th tunnel, and only 73 tunnels were created successfully. Can anyone give me some advice on the reason of this symptom ? Is there any limitation for the number of users ? I attached a PPT file to describe in detail, with topology, HW info and logs. If further info is needed, don`t hesitate to let me know. Any advice will be appreciated. Thank you ! Regards, Li

Hi everyone, this is my first post in this fórum, so if I write something and this is ansewred in another time, please tell me. I'm configuring a freeradius server for a ISP provider, and I need to deliver for clients public Ip addresses but this one need to be static at the same time, because is the main poli of the network. I'm using sqlippool for delivery IP addresses for clients but I don't want use this for public IP addresses, just for private. The ippool is working fine.

Efficient AD group matching via the new wbclient interface
by Isaac Boukris 12 Apr '18

12 Apr '18

Hello all, I am working on improving AD group matching for mschap authentication, taking advantage of the new wbclient direct interface which returns the user's token (including group membership SIDs) as part of NTLM authentication. Work in progress: https://github.com/frenche/freeradius-server/commit/9af7dfd634a251f68b07064… I'm now thinking on how to implement the caching of group-name to SID mapping with configurable timeout, ideally using existing interface - ideas welcome. @mcnewton, I noticed at last there is a similar group-compare function in v4 branch, though I think the two actually can complete each other. Thoughts? Thank you, Isaac B.

Catching DB errors in sqlippool
by Бенджамин Томпсон 11 Apr '18

11 Apr '18

Hi I have a test setup consisting of three servers and on each of them is installed FreeRADIUS (3.0.12) and one node of a Percona MySQL cluster. FreeRADIUS is configured to allocate IP addreses from the database using sqlipool. Authentication data is stored elsewhere. The idea was to build a fully redundant system which could cope with loosing one or more nodes of the backend DB. It was very easy to set up and I generated some load with radperf and did some testing and everything generally worked apart from a couple of problems. The first problem I noticed is that when requsts are sent to multiple DB nodes at the same time, the DB sometimes throws a cluster conflict error. This error is picked up by the sqlippool module and this is how it looks in the logs: ERROR: (220) sqlippool: rlm_sql_mysql: ERROR 1213 (WSREP detected deadlock/conflict and aborted the transaction. Try restarting the transaction): 40001 As there was a problem with the transaction I wanted to configure FreeRADIUS either to retry the request to the DB or to silently drop the packet. The problem is that the module returns the code ok: Debug: (220) modsingle[post-auth]: calling sqlippool (rlm_sqlippool) Debug: rlm_sql (sql): Reserved connection (9) Debug: %{User-Name} Debug: Parsed xlat tree: Debug: attribute --> User-Name Debug: (220) sqlippool: EXPAND %{User-Name} Debug: (220) sqlippool: --> testusername111 Debug: (220) sqlippool: SQL-User-Name set to 'testusername111' Debug: START TRANSACTION Debug: Parsed xlat tree: Debug: literal --> START TRANSACTION Debug: (220) sqlippool: EXPAND START TRANSACTION Debug: (220) sqlippool: --> START TRANSACTION Debug: (220) sqlippool: Executing query: START TRANSACTION Debug: SELECT framedipaddress FROM radippool WHERE pool_name = '%{control:Pool-Name}' AND (pool_key = '%{User-Name}' or expiry_time < NOW()) ORDER BY (pool_key <> '%{User-Name}'), expiry_time LIMIT 1 FOR UPDATE Debug: Parsed xlat tree: Debug: literal --> SELECT framedipaddress FROM radippool WHERE pool_name = ' Debug: attribute --> Pool-Name Debug: literal --> ' AND (pool_key = ' Debug: attribute --> User-Name Debug: literal --> ' or expiry_time < NOW()) ORDER BY (pool_key <> ' Debug: attribute --> User-Name Debug: literal --> '), expiry_time LIMIT 1 FOR UPDATE Debug: (220) sqlippool: EXPAND SELECT framedipaddress FROM radippool WHERE pool_name = '%{control:Pool-Name}' AND (pool_key = '%{User-Name}' or expiry_time < NOW()) ORDER BY (pool_key <> '%{User-Name}'), expiry_time LIMIT 1 FOR UPDATE Debug: (220) sqlippool: --> SELECT framedipaddress FROM radippool WHERE pool_name = 'POOL1' AND (pool_key = 'testusername111' or expiry_time < NOW()) ORDER BY (pool_key <> 'testusername111'), expiry_time LIMIT 1 FOR UPDATE Debug: (220) sqlippool: Executing select query: SELECT framedipaddress FROM radippool WHERE pool_name = 'POOL1' AND (pool_key = 'testusername111' or expiry_time < NOW()) ORDER BY (pool_key <> 'testusername111'), expiry_time LIMIT 1 FOR UPDATE Debug: (220) sqlippool: Allocated IP 10.192.0.110 Debug: UPDATE radippool SET nasipaddress = '%{NAS-IP-Address}', pool_key = '%{User-Name}', callingstationid = '%{Calling-Station-Id}', username = '%{User-Name}', expiry_time = NOW() + INTERVAL 3600 SECOND WHERE framedipaddress = '10.192.0.110' Debug: Parsed xlat tree: Debug: literal --> UPDATE radippool SET nasipaddress = ' Debug: attribute --> NAS-IP-Address Debug: literal --> ', pool_key = ' Debug: attribute --> User-Name Debug: literal --> ', callingstationid = ' Debug: attribute --> Calling-Station-Id Debug: literal --> ', username = ' Debug: attribute --> User-Name Debug: literal --> ', expiry_time = NOW() + INTERVAL 3600 SECOND WHERE framedipaddress = '10.192.0.110' Debug: (220) sqlippool: EXPAND UPDATE radippool SET nasipaddress = '%{NAS-IP-Address}', pool_key = '%{User-Name}', callingstationid = '%{Calling-Station-Id}', username = '%{User-Name}', expiry_time = NOW() + INTERVAL 3600 SECOND WHERE framedipaddress = '10.192.0.110' Debug: (220) sqlippool: --> UPDATE radippool SET nasipaddress = '127.0.0.1', pool_key = 'testusername111', callingstationid = 'testusername111', username = 'testusername111', expiry_time = NOW() + INTERVAL 3600 SECOND WHERE framedipaddress = '10.192.0.110' Debug: (220) sqlippool: Executing query: UPDATE radippool SET nasipaddress = '127.0.0.1', pool_key = 'testusername111', callingstationid = 'testusername111', username = 'testusername111', expiry_time = NOW() + INTERVAL 3600 SECOND WHERE framedipaddress = '10.192.0.110' Debug: rlm_sql_mysql: Rows matched: 1 Changed: 1 Warnings: 0 Debug: COMMIT Debug: Parsed xlat tree: Debug: literal --> COMMIT Debug: (220) sqlippool: EXPAND COMMIT Debug: (220) sqlippool: --> COMMIT Debug: (220) sqlippool: Executing query: COMMIT Debug: rlm_sql_mysql: No additional diagnostic info on server ERROR: (220) sqlippool: rlm_sql_mysql: ERROR 1213 (WSREP detected deadlock/conflict and aborted the transaction.

In this case the module returned notfound and as I understand it I could use some unlang to send the request again (I'm not sure how many times it's wise to to this). However, I also tried to drop the request by calling do_not_respond when Framed-IP-Address is empty, but I found that this did not prevent the request from being sent: Debug: (222) if (!&reply:Framed-IP-Address) { Debug: (222) if (!&reply:Framed-IP-Address) -> TRUE Debug: (222) if (!&reply:Framed-IP-Address) { Debug: (222) policy do_not_respond { Debug: (222) update control { Debug: (222) &Response-Packet-Type := Do-Not-Respond Debug: (222) } # update control = noop Debug: (222) modsingle[post-auth]: calling handled (rlm_always) Debug: (222) modsingle[post-auth]: returned from handled (rlm_always) Debug: (222) [handled] = handled Debug: (222) } # policy do_not_respond = handled Debug: (222) } # if (!&reply:Framed-IP-Address) = handled Debug: (222) } # post-auth = handled Debug: | %{reply:Framed-IP-Address} Debug: Parsed xlat tree: Debug: literal --> | Debug: attribute --> Framed-IP-Address Debug: (222) EXPAND | %{reply:Framed-IP-Address} Debug: (222) --> | Auth: (222) Login OK: [testusername112/testpassword112] (from client localhost port 0 cli testusername112) | Debug: (222) Sent Access-Accept Id 28 from 127.0.0.1:1812 to 127.0.0.1:54122 length 0 I would be grateful for any help or advice on these issues.

RADIUS wifi not working on Windows with domain users
by Forster Arnaud 10 Apr '18

10 Apr '18

Hello all, I've a problem in a school with computers connected to the school domain (I'm using samba). For private computers, there's no worry ; they are asked to enter a username/password to connect to the wifi and this works fine. But for laptops belonging to the domain, when I try to connect, no username/password is requested and the connection just fail. It seems this is a windows problem but I wonder If I can don something from the freeradius side ... thanks to all for your help -- Meilleures salutations – Freundliche Grüsse – Best regards MW*PROGRAMMATION*SA *Arnaud Forster* /Ingénieur systèmes// //Rue Charles Schäublin 2/ /CH-2735 Malleray/ /phone: +41 (0)32 491 65 30/ /fax: +41 (0)32 491 65 35/ /web: www.mwprog.ch <http://www.mwprog.ch/>/ /kb: kb.mwprog.ch <http://kb.mwprog.ch/>/

I use radius in mikrotik and i have multiple radius account in mikrotik for different services.
