thanx alan..
But i searching around on web i came to know that radclient can also be used for load testing. But when i use this with -p (to send requests in parallel), it only send one packet. here is the command out put
[root@billing ~]# echo "User-Name=001AAD3F8165,
NAS-IP-Address=10.192.100.4"|radclient -p 100 192.168.0.102 auth
testing123 -xSending Access-Request of id 120 to 192.168.0.102 port 1812
User-Name = "001AAD3F8165" NAS-IP-Address = 10.192.100.4
rad_recv: Access-Accept packet from host 192.168.0.102 port 1812,id=120, length=143
Qos-Policing-Profile-Name = "128K_UL" Qos-Metering-Profile-Name = "512K_DL"
Context-Name = "Postpaid-VR" DHCP-Max-Leases = 1
Forward-Policy = "in:nonpayment_redirect_post" HTTP-Redirect-Profile-Name = "nonpayment_redirect"
why dont -p sends requests in parallel ?????
