Rejecting User By their Calling-Station-Id (Mac Address)
by Alex M 26 Dec '09

26 Dec '09

Hey all, i'm coming back here w/ my old question of how to reject users based on their MAC address... but now im running FR 2.x.x So, we have trial access for free, and some people figured that they can re-register new accounts for trial all over again and have fun this way. Well thats not fun for us so we trying to figure out what we can do to reject reqyest from their machines no matter what name they put in. So maybe some one can help me out here. Here is what I tried: *radusergroup* (username, groupename, priority) <all user-names registered> Ban 9999 Test_User Home 1 *radgroupcheck* (groupname, attribute, op, value) Ban Calling-Station-Id == 00:0b:6a:xx:xx:xx Ban Reply-Message == You have been banned Ban Auth-Type := Reject *radcheck* (username, attribute, op, value) Test_User password == letmein So far that dint work at all... I tried changing priority but no matter what I do the user still authorized to enter the network. I'm sure I did something wrong but im not sure what? So maybe some one can help me out? Thanks a lot!

How freeradius mapping the attributes when save records into radacct table?
by Zhang Shukun 26 Dec '09

26 Dec '09

hi, all Merry Christmas！ i want to how freeradius map the attributes between vendor specific attributes and radius usuall attributes. for example. i have attributes from asterisk send to radius, attributes and data as follows: Acct-Status-Type = Stop Asterisk-Src = "5678" Asterisk-Dst = "4321" Asterisk-Dst-Ctx = "tutorial" Asterisk-Clid = "\"Jane Smith\" <5678>" Asterisk-Chan = "SIP/ivan-00000004" Asterisk-Dst-Chan = "SIP/test-00000005" Asterisk-Last-App = "Dial" Asterisk-Last-Data = "SIP/test" Asterisk-Start-Time = "2009-12-23 16:00:48 +0000" Asterisk-Answer-Time = "2009-12-23 16:00:53 +0000" Asterisk-End-Time = "2009-12-23 16:02:49 +0000" Asterisk-Duration = 121 Asterisk-Bill-Sec = 116 Asterisk-Disposition = "ANSWERED" Asterisk-AMA-Flags = "DOCUMENTATION" Asterisk-Unique-ID = "1261584048.4" User-Name = "SIP/ivan-00000004" Acct-Session-Id = "1261584048.4" NAS-Port = 0 Acct-Delay-Time = 0 NAS-IP-Address = 127.0.0.1 but when sended to freeradius and saved to mysql table radacct, record shows as follow, | 15 | 1261584048.4 | acb68819c2f8e979 | SIP/ivan-00000004 | | | 127.0.0.1 | 0 | | 2009-12-24 00:02:49 | 2009-12-24 00:02:49 | 0 | | | | 0 | 0 | | | | | | | 0 | 0 | NULL | as you see, many attributes not saved to the table radacct, there are lost. My question is how freeradius know the mapping between them(the attributes)? if i want to change the attributes(add or remove ) for the mapping? what should i do? modify the src codes of freeradius ? or do others -- Thanks, Sucan

Access-Request / Mandatory Attributes
by rsg 24 Dec '09

24 Dec '09

Hi, I find that FreeRadius server allows access even without either of the mandatory attributes i.e. NAS-Identifier or NAS-IP-Address in the Access Request packet. Is this a deviation from RFC 2865 ? " .....An Access-Request SHOULD contain a User-Name attribute. It MUST contain either a NAS-IP-Address attribute or a NAS-Identifier attribute (or both)." Can someone clarify this please? Many thanks, rsg.

Hi, I have freeRadius server connected to Cisco Router as PPPoE Server (Remote Access Server). I can limit customers' bandwidth limit by using Rate-limit function. But I want to give unlimited bandwidth to some specified IPs. Also time-based (I mean at the midnight I can give no bandwidth limitation to the customers.) How can I make it in freeradius? Thanks

How to set servers file in radiusclient-ng install ?
by Zhang Shukun 23 Dec '09

23 Dec '09

" is that say i must set the hostname of a RADIUS server, could i set IP addr of the RADIUS server? Thanks! -- Regards, Sucan

escape in the radius accept
by Ning Shi 23 Dec '09

23 Dec '09

hello folks, I am working on a EAP issue. the user could authenticated ok. however, if the username is like this: "edu\nntest" (wihch is ' 45 44 55 5c 6e 6e 74 65 73 74) then in the radius accept, the username changed to "edu'0x0a'ntest" (45 44 55 0a 6e 74 65 73 74) so the '\n' has been converted to 0x0a. this doesn't affect the authentication but it does affect the display on the authenticator. I tried to search the list but couldn't find similar question. if anyone has any workaround, please advise. I don't have the radius debug log since this is on a production server but I don't have the packet capture in case someone is interested. Regards, -ns

Virtual Server not setting attributes on reply
by Timothy 23 Dec '09

23 Dec '09

Hi, I'm having problems when using a virtual server. When using the "virtual_server" I'm not getting the reply attributes set. It may be a config thing, but I haven't been able to find where the problem is from the documentation. And I can't understand why there would be the difference. I have 2 realms set using the same virtual server. The only difference is realm TEST1 { virtual_server = test } realm TEST2 { type = radius format = prefix delimiter = "/" authhost = 127.0.0.1:11812 accthost = 127.0.0.1:11813 secret = secret } If I authenticate to TEST1/user My response is "only" a successful auth. If I authenticate to TEST2/user My response is a successful auth WITH Attributes (in this case the attribute I'm setting is Cisco-AVPair = "shell:priv-lvl=15" It appears to me that using the virtual server is stripping the attributes from the reply. Can anyone tell me a) The approprate documentation covering this is so I know. b) What I have done wrong (and where to find the answers) or c) This is an actual bug and someone will look at it Thanks Timothy
