Hi guys I am running freeradius ver 2.2.6.7 on CentOS 6.0. I have configured freeradius with sql_counter module and all is working fine: users are disconnected when they reached the time or traffic assigned. Now my goal is to implement CoA on freeradius in order to update the Time (Session-Timeout) and Traffic (Mikrotik-Xmit-Limit) attribute, every time the NAS server (Mikrotik) sends the interim update packet, : how can I achieve that? I add this inside the accounting section of the file /ETC/SITE-AVAILABLE/DEFAULT #COA update coa { User-Name = "%{User-Name}" Acct-Session-Id = "%{Acct-Session-Id}" NAS-IP-Address = "%{NAS-IP-Address}" Framed-IP-Address = "%{Framed-IP-Address}" Session-Timeout = "%{Session-Timeout}" } update control { Send-CoA-Request = Yes } and this inside CLIENTS.CONF: client 0.0.0.0/0 { secret = xxxxxxx require_message_authenticator = no nastype = other } #COA home_server piazzalaterale-coa { type = coa # # Note that a home server of type "coa" MUST be a real NAS, # with an ipaddr or ipv6addr. It CANNOT point to a virtual # server. # ipaddr = 192.168.0.201 port = 3799 # This secret SHOULD NOT be the same as the shared # secret in a "client" section. secret = xxxxxx # CoA specific parameters. See raddb/proxy.conf for details. coa { irt = 2 mrt = 16 mrc = 5 mrd = 30 } } but when the CoA packet is sent to the NAS the Session-Timeout attribute is set to 0 instead of to the residual credit time of the user. I need that because if two people log-in simultaneosly with the same username, they should share the credit time/traffic instead, without CoA, they will both have the same credit Sorry for my English....I hope to have been clear Best regards Con MyOpen hai Giga, SMS e i minuti che vuoi da 3€ al mese, per sempre.
