I want to add a second radius server (freeradius) to handle requests when the main one is experiencing problems.
What is the best approach to this. Do i enable accounting backup on the main radius server and add the ip to the backup radius server?
Set the second server up under /radius and check accounting backup on both servers. They should then both receive all RADIUS ACCOUNTING packets. The first server will be tried for authentication, if it times out (no reply at all) the second server will be tried.
I have done as u said and immediately i get RADIUS accounting request not sent but if i uncheck accounting backup from the main server but leave the other checked it stops. So do i check one or both?
I guess you check just one. Test it - log in and see if you get accounting records to both.
I just checked one and it works like a charm now i have to test when one is off
I noticed one server has to be marked accounting backup but if the first radius server fails the second one doesn’t automatically take over (failover) I have to do it manually. Is there a way to automate the failover solution?
