Hello, I have a big problem please HELP. I newbee for Radius, I am use freeradius 2.x on the Suse 11.1. (Vmware ESXi 3.5) I use ippool. (254 IP) I have a gprs POS machine. POS is work no problem but, When connect POS machine to radius server, and disconnect, ippool not free ip on the db. I look rlm_ippool_tool -avc db.ippool db.ipindex ip's still here. Many times db file is full and radius not give ip to POS. I manualy remove this rlm_ippool_tool -r command and Radius give IP to POS. I look Radius -Xx command, i see on the log file error : rlm_ippool: No available ip addresses in pool. Q1: How release IP on the db.ippool file auto? or any disconnection timeout value? Note: I use crontab now, but is this true way? Thank you. Some Information from Radius ippool main_pool { range-start = 172.20.3.1 range-stop = 172.20.3.254 netmask = 255.255.255.0 cache-size = 254 session-db = /var/lib/radiusd/db.ippool ip-index = /var/lib/radiusd/db.ipindex override = no maximum-timeout = 600 (Not work..????) }
