RADIUS Load Balancing

Hello,

 

 

I have to use 2 radius server in failover authentification.

 

 

1 - The Firsty idea is to create Virtual server for radius with a monitor which just check that radius answer although it is a radius-reject (for security purpose we do not want to use a user password to test, we will test with a wrong username)

 

 

Does anyone know all the command line of /usr/bin/monitors/builtins/RADIUSACCT_monitor /usr/bin/monitors/builtins/RADIUS_monitor

 

the idea is to create a monitor script which use RADIUS?_monitor and send Ok if there is answer and send NOK with no answer, that's all.

 

 

2 - The second idea is to modify the authentication irule for disabling the active node if there is an authentification error (not a reject).

 

If auth failed

 

=>check node up, if node up make it down

 

=>check node down, if node up make it up

 

 

I prefere the 1st idea,

 

 

Thanks for your help,

 

 

Flo,

    The code flomkrl posted is used in an external monitor. USERNAME="TEST" is where he is setting the login name.

     

     

    These two pages have some background info on external monitors and using an external monitor to check a radius pool:
