Re: Accounting - FramedIPAddress - DHCP/IPPOOL
So even though the AP must know the information, we are unable to get it into the radius accounting? We have to script the coordination between the DHCP server? ============================ Message: 4 Date: Wed, 10 May 2006 12:52:36 -0400 From: "Alan DeKok" <aland@nitros9.org> Subject: Re: Accounting - FramedIPAddress - DHCP/IPPOOL To: FreeRadius users mailing list <freeradius-users@lists.freeradius.org> Message-ID: <20060510165236.00C2F16CC1@mail.nitros9.org> mad <psymad@gmail.com> wrote:
I have a problem with the ip address ... because it's dhcpd who give an ip address at the client, so freeradius can't have this information.
Exactly.
I have try ippool in freeradius (freeradius want to give an ip address but the client don't receive). Also I have read that it's impossible to use ippool with eap and when there are access point and/or swith between client and server ... it's true ?
It's impossible to use ippool with EAP.
I have also try other solutions (with syslog-ng who get the ip address in the log and insert in acct table ..., a scripts with omshell who permit to freeradius to indicate at dhcpd what ip address give at this client ...) BUT I think this solution are very unstable ...
A well written DHCP server should be as flexible as FreeRADIUS, and allow you to write the IP to an SQL table. Unfortunately, there is no such DHCP server. Alan DeKok. -- Walter Reynolds University of Michigan

Yes. Although the AP does not necessarily "know" the information. If it's running a DHCP server, it knows. Otherwise, it would have to sniff DHCP traffic, and compare MACs from EAP to those in DHCP. Most AP vendors haven't written the code to do DHCP sniffing, so... no IP's in RADIUS accounting packets.

Yes. Alan DeKok.

Yes.
For to be sure to understand ... There are scripts who permit to coordinate the AP information for accounting and the dialog dhcp client/server ... the AP can take the information of dhcp dialog ... Sorry if I say an error ... I have client wireless and wire ... What is it possible with the switch ? (cisco2950) Thanks
