If your NAS supports several Radius servers, I wouldn't do any clustering, but run them in parallele adding each server's IP in the NAS config. It will detect when a server is unreachable and switch all traffic to other servers. Problem with LVS is you become dependant on your OS. If your NAS does not support multiple servers, I'd go for LVS or Heartbeat David Roze --- http://www.netexpertise.eu -----Original Message----- From: freeradius-users-bounces@lists.freeradius.org [mailto:freeradius-users-bounces@lists.freeradius.org] On Behalf Of Nicolas Baradakis Sent: 16 October 2007 11:59 To: FreeRadius users mailing list Subject: Re: Freeradius Clustering Fred Zinsli wrote:
I am wanting to know if Freeradius can be clustered? and if so can someone point me to some documentation on the subject.
I'd suggest to use LVS (Linux Virtual Server) in a "direct routing" setup. See: http://www.linuxvirtualserver.org/VS-DRouting.html
I am also wanting to know how the calculate the new specs for the new servers.
Any ordinary PC will do fine. The number of req/s will likely be limited by the backend database. -- Nicolas Baradakis - List info/subscribe/unsubscribe? See http://www.freeradius.org/list/users.html
