Hello all! I´m a begineer on radius. I will install radius on two systems : windows and linux ( each one in a separate network and different environments ). my question : How many concurrent users can be authenticated on radius? where can I see the radius restrictions ? Is there a academic version of radius? ( I work in an University ) Thanks in advance. Regards.
Hi,
my question :� How many concurrent users can be authenticated on radius? where can I see the radius restrictions ?
concurrent users or authentications per second? once a user authenticates then they are online for as long as their session before a reauth (unless session-timeout is varies, or CoA used etc).
Is there a academic version of radius? ( I work in an University )
errr? this is FreeRADIUS ;-) alan
Hello Alan. Thank you for your support. At this moment I don´t think if authentications per second matter. So, I suppose that there aren´t limit for concurrent users...right? Regards. On Tue, Aug 2, 2011 at 3:10 PM, Alan Buxey <A.L.M.Buxey@lboro.ac.uk> wrote:

Short version: yes. Long version: depends. Some setups use interim-update, where the NAS would send accounting packets to radius at a specified time interval for every connected user. Each accounting packet would usually equal to disk write (either to detail file or database). While freeradius itself doesn't enforce a hard limit, your disk will most likely be a limiting factor since it has limited IOPS. So if you use short interim update interval (e.g. 5 minutes), and you log accounting packets to database, and you have slow disks, then you'll probably see a practical limit of number of concurrent users before the radius server becomes unbearably slow. Again, the limit is not in freeradius. -- Fajar
