I have a few hours reserved this afternoon to finish off the MySQL testing, so I'm up for it. Yep. The problem I have with this change though is that what are the other vendor disconnect keys? If you read the RFC it doesn't specify a specific key (Alan has been holding ongoing discussions about this on the ietf-radext list), just that there should be enough info to identify the correct session. As Cisco also uses it (and Juniper from AFAIK) XAscendSessionSvrKey has become a de-facto standard along with MS-Primary-DNS-Server and its ilk. Given that it is possible to send and have work a Disconnect-Request containing only a User-Name and there is no-where specified that there should be an individual session key I am not sure its worth changing unless someone can come up with a concrete example of a vendor who uses a session key thats different Is there?

And seeing as it's a VSA for Ascend boxes, I don't see why it would be used in any other kit ? Cisco's use it. Maybe we should call the DB colum disconnect-key or something similar... RFC just states that a packet with Code 40 should be sent, including a list of identification attributes, and an optional Service-Type attr with value Authorize Only, if only requesting termination of a session and not CoA, to avoid ambiguous meanings of attributes, and ease translation to Diameter. On NAK NAS is also supposed to send an Error-Cause attr, describing the reason for the NAK. The fact that the Request Authenticator matches, should be enough to ensure the Disconnect Message came from an authorised local RADIUS server, and the RFC describes a reverse proxying method to use for use when proxying...

Re: Reccomended switches for dynamic vlans
additional comment on procurve switches: If you want to authenticate more than one client on a port you need multidomain authentication support. This is available on hp3500yl and up(comparable with cisco 3500 series i think) the 26xx is indeed a good cheap poe switch(only 10/100 but that should be enough for poe application) Almost all managed procurve switches support the same security features(certainly from 26xx and up), so that makes it easier to combine different models in your network without sacrificing security. most of the difference is in port speed and routing functions and whether it is chassis based or not. I can also recommend the 5400 chassis based switch. largest model can handle 12 modules(also available in 6 modules) which you can fill. cat5 modules for this switch are always 10/100/1000 with poe or modules for mini-gbics(chassis itself is quite cheap, and modules are also ok but only interesting if you have centralized cabling). one disadvantage of the procurves is that they don't support hardware stacking(for procurve stacking is only a management feature) to built a virtual chassis with a high speed backbone link between 2 or more switches(i think cisco has models that can do this, but also not all). regards, Stieven Struyf M.I.S.

Unfortunately these do not support POD (packet of disconnect) but apparently this can be achieved via SNMP. All dynamic VLANS must have been setup on the switch before being assigned, or now with later firmware they can be learned (though this tends to break with larger installations). Here’s the wiki page http://wiki.freeradius.org/HP For wireless, depends... do you want a centrally managed wireless infrastructure, or each WAP to be a fully functioning WAP in it's own right. If it's the latter then HP530s are a safe bet. The firmware is currently pretty buggy, but the hardware is sound. They support: Multiple BSSIDS (with fully customisable settings for each). Dynamic VLAN assignment SNMP Trigger events for loads of things. Ingress rate limiting via VSA Learning of tagged VLANS from their uplink (which is really neat) Accounting for security enabled BSSIDS (though not necessarily radius authenticated) POE they also have dual radios, so you can run b/g on one and a on the other, or buy external aerials and run both b/g. There’s also a USB expansion slot marked for use in later firmwares could be an 11n upgrade module? Don't support Radius admin login authentication No obvious method of disconnecting users Current Major Bugs Accounting doesn't send interim update packets properly for all BSSIDS, so you sometimes lose data transferred type info. Vlans assigned statically to a BSSID cannot then be assigned dynamically (users traffic just gets black holed). Disabling of the plaintext web server breaks DHCP (most random bug ever). When user changes from one BSSID to another, accounting gets very confused (sometimes). But we still brought 30 of them, as we have faith in HP that these issues will be fixed. Also do a really neat thing where the base can slip onto the t bars of suspended ceilings, then you run a LAN cable above the ceiling with POE... And it looks like it's a wireless wireless access point :) And at £320 a unit, yes they do include a Kensington lock slot. - List info/subscribe/unsubscribe?

Now FreeRADIUS supports return codes in cvs head again, it's a good idea to elect a secondary users file module to do authorisation in place of any of your db modules, if a db module should return fail... or you could stick it at the end of a fail-over group. - List info/subscribe/unsubscribe?

Yep. You will generally need to know the the disconnect key, but you will notice that I added a field titled XAscendSessionSvrKey to radacct a while back.. A couple of lines of perl and it all just works... Is that just the SessionId on most NASes ? No Erg i'm going to have to read RFC 3576 :( I suggest you start with my summary here: http://wiki.freeradius.org/Disconnect_Messages Cheers -- Peter Nixon http://peternixon.net/ - List info/subscribe/unsubscribe?

And seeing as it's a VSA for Ascend boxes, I don't see why it would be used in any other kit ? RFC just states that a packet with Code 40 should be sent, including a list of identification attributes, and an optional Service-Type attr with value Authorize Only, if only requesting termination of a session and not CoA, to avoid ambiguous meanings of attributes, and ease translation to Diameter. On NAK NAS is also supposed to send an Error-Cause attr, describing the reason for the NAK. The fact that the Request Authenticator matches, should be enough to ensure the Disconnect Message came from an authorised local RADIUS server, and the RFC describes a reverse proxying method to use for use when proxying... Just need HP kit to support POD and CoA now ... - List info/subscribe/unsubscribe? See http://www.freeradius.org/list/users.html
