fail over

RouterOS The User Manager
1

Hi
using a RB1100 AHx4 as radius server with the user manager…
is there a way to have a fail over server? For instance a second RB1100?
can you synchronize the two user managers?

Thanks
Dirk

No clue about UM but otherwise its this:

I have not tried this, but… You likely can do some warm/cold standby by copying the sqlite DB file and have matching config on both routers. But there is NO built-in “sync”, so this be a manual/scripted processes to copy the DB file from one router to other.

And, as noted above, you could add VRRP to use that as the RADIUS address for remote clients to UM - you’d just want to make sure the master has a higher priority so the “primary” one is always picked by VRRP. And if you script a copy of DB periodically, or, perhaps, store on NAS so both side are working with same sqlite DB file.

I didn’t know VRRP and I will study it! Thanks itimo01..

@Amm0: in all my installations there is a ‘master’. In fact a PC with mirrored harddisk wich contain µsoft SQL databases, C# software etc.
So the ‘master’ could be de NAS you’re refering to. But in old posts I read that moving UM databases is not obvious…
Maybe a VM on the ‘master’ running ROS??

I’ll try everything out!
Thanks
