max_requests variable in radiusd.conf

[Claudio Carvalho]

Hi Alan,


Using the phrase "The maximum number of requests which the server keeps track of", my first understanding is that somehow the freeradius daemon is doing let's say in memory a control of the opening and closing of sessions "track of", you are saying this does not happen, everything is done through the information of the database enabling the use of multiple servers, right?


"The maximum number of requests which the server keeps track of. This should be 256 multiplied by the number of clients. e.g. With 4 clients, this number should be 1024"


Thanks,


 
Claudio.

  The comments in the radiusd.conf file document what out controls: the number of packets *currently being processed* by the server.

  It's all in a DB.

> I ask because if the session control is made entirely in the daemon without intervention of the database and it is necessary to work with load balance, the connections that arrive in this 2 freeradius servers must be tied "sticky" to the source IP, if you balance all connections without "sticky" feature this control would be broken , i'm correct?

  No.  If accounting packets go to two destinations (RADIUS servers or DBs), then those records have to be reconciled.  That's it.
