External Authentication program problem

[Ali Majdzadeh]

FYI: This is not a perl script. It’s a compiled C program. Just its
extension is .pl!

For more  information:



This is my module config:



        exec netbill_pre_auth{

                wait = yes

                program = /etc/netbill/preauth.pl"

                input_pairs = request

                output_pairs = config

                packet_type = Access-Request

        }

        exec netbill_post_auth {

                wait = yes

                program = /etc/netbill/auth.pl"

                input_pairs = request

                output_pairs = reply

                packet_type = Access-Request

        }

        exec netbill_acct {

                wait = yes

                program = /etc/netbill/acct.pl"

                input_pairs = request

                output_pairs = reply

                packet_type = Accounting-Request

        }



So I need to use with exec-wait becos the external programs need to wait
util authentication/authorization/accounting done!

Also plz note that auth.pl forks another exec program per authenticated
user (named calc) and will live till user stopped. So if I’ve 20.000 online
users, I’ve also 20.000 calc process.



It works for about 20.000 online user and after this threshold, it stops!



What is ur recommendation?

Another Q:


Is there any way to call nebtill_acct with wait=no?
