Two of them are Cisco 5800 and the rest are Cisco 3640/3660. We have two radius servers, one serving the South of Greece (including Attika which hosts the main 5800 access server with 600 lines) and the other serving the North of Greece (which includes the other 5800 with 150 lines). Both radius servers act as a backup for the other. The user database is in LDAP (iPlanet DS5.1) while the accounting is maintained in MySQL+InnoDB databases. Each server replicates the accounting information through radrelay to the other one. That way we maintain full accounting on each server and can enforce national double login detection and also have nice redundancy. The LDAP and MySQL databases are hosted on the same machines as are the radius servers (meaning we have 2 LDAP/MySQL/RADIUS servers). The machines are Sun E450 with 1GB RAM and Solaris 8 each We do a lot of attribute rewriting through the attr_rewrite module and we have also enabled the detail accounting module for radrelay to work. The schools connect on demand (when there is a request for something from the internet) so we get a *lot* of connections. For weekdays we get around 10 connections per day. Here is a typical top output. As you can see freeradius has no problem handling the load.

RE: Maximum/Ideal/Suggested number of users (current and possible)
Performance: I presently run 148 ports on a 400 MHz Solaris system that all runs a very busy e-mail server. At that I average about 75% idle cpu cycles. I doubt that FR's contribution to the load would be measurable. I do use MySQL back-end. Reliability: No standalone computer achieves 5 9's of reliability on it's own. I run FR on two servers, and you should too if reliability is important. IMHO a database backend makes redundant servers a little easier, but you will get differences of opinion on this. One great thing about a database backend on FR is that there is no need to restart the server every time you add a user. With 10K subs I would definitely recommend a DB backend. As to which one, everbody is different. I use MySQL, but would use Oracle if cost was not a factor. Other's use Postgres, and I think some even use MSSQL Tim > -Original Message- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED]]On Behalf Of Tim Rich, > Jr. > Sent: Thursday, February 06, 2003 1:20 PM > To: '[EMAIL PROTECTED]' > Subject: RE: Maximum/Ideal/Suggested number of users (current and > possible) > > > Thanks, Tim - > Then some details are available: > > We currently serve ~1500 users, max concurrent connection = 96 users. > The proposed radius server is a Compaq Proliant DL380, Dual 2.4 > Xenon CPU, 4 > GB memory, attached to a SAN.

Wow, that's quite a bit of overkill.

Thanks, Tim - Then some details are available: We currently serve ~1500 users, max concurrent connection = 96 users. The proposed radius server is a Compaq Proliant DL380, Dual 2.4 Xenon CPU, 4 GB memory, attached to a SAN. This server is running Redhat 7.3 (testing to move to Redhat AS 2.1). The device making Radius requests is a Cisco 5300 Access server connected to 4-24 Channel T-1's. These devices are connected on a 10/100 Ethernet segment. This is the bulk of our business - and would need 99.999 availability. Our peak usage is 5 hours a day, but still only see about 60 current connections. Typical connection length is between 8 and 20 minutes. The growth of our company is anticipated to be added users of ~ 10,000 this year, as we just signed a large contract. Our ratio of users/available (concurrent) connections is about 1/15.

Greetings - I am doing research regarding whether or not to replace our Windows 2000 ADS/Radius server with .? In this search I have come across Cistron/FreeRadius; however, I have not seen any benchmarks/suggested maximum number of users. I welcome any suggestions. Thanks!
