Dynamic Attributes Based on NAS Type !
Hi Everyone ... Currently i am planning to integrate freeradius with different NAS like Chillispot , Cisco etc and enable roaming users so that they can log in from any of the NAS. As the reply items are different with different NAS , i am looking for ideas how to enable a single user to roam and connect from different NAS. In my case i think static reply items are not possible per user wise or per groupwise so my question is what trick can be used to achieve the same. I had not tried anything as i have no clue on the same so some highlights on the approach will be a good starting point for me. Cheers Suman - List info/subscribe/unsubscribe?

RE: Dynamic Attributes Based on NAS Type !
Suman, As you did not say anything about the exact attributes, you will send to the NAC, here is how we do this: we are also using different NAS and have to reply with different VSAs for setting up the QOS. We use the existence of a specific VSAs (specified per NAS type) in the request to select the VSAs to be used in responses. e.g: if we found the Starent Networks VSA 'SN-Service-Type' in the request, we reply with 'SN-QOS-Profile' to set up QoS This is save, as we won't see any Starent VSAs in Cisco or Chillispot NASses. To make this flexible, we have set up our own VSA to configure users QOS, which is then translated into the specific reply attributes for the NAS, the user is currently using.

Re: Dynamic Attributes Based on NAS Type !
To be specific , I am concerned about the QoS VSA's . For Example. Mikrotik NAS - Mikrotik-Rate-Limit Chillispot - Chillispot-Max-UP , Chillispot-Max-Down Cisco - Cisco-Policy-UP , Cisco-Policy-Down Now if the user logged from different NAS's the VSA will differ so it is not possible to have a single entry in radgroupreply or radreply pertaining to a kind of NAS. I guess that this is not an out of the box feature in freeradius , instead i need to use some kind of custom script in Post-Auth section which will check the NAS Type and reply out the correct VSA's I am looking for a unique identifier from NAS by which freeradius can understand what type of NAS it is. I tried it and it seems that i have no control on the Access-Request sent by NAS to freeradius. The only idea which currently comes into my mind is to use nas.type value in DB but incase the NAS Type is incorrectly specified reply attributes will go nuts . So any idea if there are any unique identifiers ?

RE: Dynamic Attributes Based on NAS Type !
It may not be pretty, but why not just sent all 3 sets of VSA's. If the NAS doesn't recognize it won't it just ignore the attribute?

AW: Dynamic Attributes Based on NAS Type !
The general idea is to setup a virtual server for each type of NAS and make sure, that every NAS is loaded into the correct virtual server.

RE: Dynamic Attributes Based on NAS Type !
Norbert, sorry, but you are taking a sledgehammer to crack the nut. If you read it one of the ideas of having different virtual servers is separation of policies for different NASses you are right. Suman was asking on how to send several NASses into the same policy.
