How EAP module set the Auth-Type to EAP when using rlm_sim_file module?
by lishuai zhao 16 Mar '07

16 Mar '07

Hi, all I am using rlm_sim_file module to perform the authorization function, so I have to add "sim_file" before "eap" in the authorize{} of radiusd.conf. In general, the authorization function can set the "Auth-Type" automatically, such as rlm_file or rlm_sql. But I find that the rlm_sim_file does not do that. In the rlm_sim_triplets of Doc, it says that :If this module is successful at retrieving three sets of triplets, then the EAP-Type: attribute will be set to SIM. The EAP module itself will set the Auth-Type to EAP when it sees the EAP-Message attribute. I only find that Auth-Type is set in the eap_authorize function. In my opinion, if rlm_sim_file is used, the eap_authorize will not be executed. So , I do not know how Auth-Type is set to EAP when using rlm_sim_file module? Best wishes! Lishuai.zhao

Reject authentication attempts based on "cli" value?
by markcapelle＠pcmc.com 16 Mar '07

16 Mar '07

It is a Cisco WLAN 4402. For reference, here is a log entry from a user connecting from the Guest network: Thu Mar 15 07:10:52 2007 : Auth: Login OK: [guestuser] (from client PCMCWLANCTRLR1 port 0 cli 192.168.100.101) And here is a log entry from someone connecting via 802.1x on another network: Thu Mar 15 07:26:36 2007 : Auth: Login OK: [DOMAIN\\guestuser] (from client PCMCWLANCTRLR1 port 1 cli 00-12-F0-19-6E-B3) As you can see the only way I have to differentiate these two auth attempts is via the "cli" value. 192.168.100.x is the subnet range of my Guest network. I want all auth attempts from 192.168.100.x to be rejected. Hope someone can help me out with this.

Programming request
by Cory Robson 16 Mar '07

16 Mar '07

I require a php script to be written that I can run from cron. The purpose of the script is to basically remove stale/locked accounting records in the sql database. Script will need to have variables defined at top of script for easy changes. (I.E. mysql database,username,password and time variables) SQL statement will need to filter on open sessions (acctstoptime = null) my NAS's are set to send acct update packets every fifteen minutes. Script will need to first look at records with acctsessiontime=0 and if elapsed time from acctstarttime is greater than 30 mins then remove or close the session. If acctsessiontime > 0 then look at last session time and look at current time and again if more than 45 minute variation close the session based on last known session update (starttime+sessiontime = acctstoptime) I'm open to tendors and can pay by paypal but looking at figures around $20 as this shouldn't be a hard task for a programmer.

Problem with Digest/OpenSER/Radius
by Dariusz Dwornikowski 16 Mar '07

16 Mar '07

Hi. My problem is such, that we store our passwords in Md5 in database, when authorization request comes from ser, i get digest attributes. I issue: authorize_check_query = "SELECT id, UserName, Attribute, Value, Op \ FROM ${authcheck_table} \ WHERE Username = '%{SQL-User-Name}' \ ORDER BY id" And in Database I have: id = 1 UserName = test001 Attribute=User-Password Value = test Now, my real database stores passwords as md5 hashes and the radius compares the clear text passwords, how can i force it to compate md5 hashes of passwords? -- Dariusz Dwornikowski tdi(a)vercom.pl

An entry like this in your 'users' file should work: DEFAULT NASIPAddress =~ "192.168.100.*" Auth-Type := Reject I'm not sure '*' is the appropriate regular expression character for freeradius, but you should be able to verify that pretty quickly from the documentation.

Question about SQL authentication.
by Kelly Hamlin 15 Mar '07

15 Mar '07

I haven't yet downloaded Free Radius, but looks to be the solutions I'm in search of. My question is this. We already have a db developed and running that maintains all customers, usersnames, passwords, static wan IP, ect. I would love to be able to have FreeRadius query my db for those fields to authenticate the user. I don't care about any of the accounting stuff since it isn't and hasn't been used in a long time. Any insight to this would be great! Kelly

RE: Reject authentication attempts based on "cli" value?
by Sam Schultz 15 Mar '07

15 Mar '07

I'm not sure what that "cli" value is. Have you checked the radius attributes page to see if it is standard? If you have any way to pull that information to the radius server external of freeradius, I suppose you could use the exec module. I doubt it would be efficient at all, though. Looks like your best bet is to pour through your radius debugging logs, and see if you can find a radius attribute that has what you need in it. If you do happen to find one, my previous suggestion would be easy enough to modify to accommodate.

Once you configure the eap module, it tends to take care of itself. Setting Auth-Type & Autz-Type are for when you want to force a user (or all users, as with DEFAULT entries) to be authorized & authenticated by the respective modules. If you're purely using ldap for authorization & authentications, you wouldn't shouldn't need to set either one. I know in my case I had to set access_attr_used_for_allow to 'no' because I wasn't using the ldap schema extension packaged with freeradius. > >Joe > > >- >List info/subscribe/unsubscribe?
