Dear friends,

I searched list archive, but I couldn’t find anything about this.  I need to correctly design and deploy a brand new FreeRADIUS server.  It will receive about 25.000 simultaneous users, so I’m planning to have, at least, two servers.

My questions are:

1. What would be recommended server hardware (memory, disk, CPU, …) and software (Linux distribution, kernel version, …)?

2. How could I synchronize both servers’ users?  I mean, in the beginning, I’d have two separate /etc/shadow files but this is not scalable.  I need to share a single file between both servers.  Is it possible?  How?

3. Any recommendations to the backup policy?

Best regards,
