Need Help on Radius - accounting respond
by Do Nguyen Ha 15 Dec '08

Hi all the FR receive the accounting request: rad_recv: Accounting-Request packet from host 172.26.0.8 port 1645, id=186, length=399 User-Name = "0873000001" NAS-IP-Address = 0.0.0.0 Service-Type = Dialout-Framed-User Class = 0x436c6173733d333030 Cisco-AVPair = "h323-incoming-conf-id=b97aff16 c99911dd 8125d127 98296413 " h323-conf-id = "h323-conf-id=b97aff16 c99911dd 8125d127 98296413 " h323-setup-time = "h323-setup-time= 4:43:17.000 UTC Mon Dec 15 2008" h323-connect-time = "h323-connect-time= 4:43:21.000 UTC Mon Dec 15 2008" h323-call-type = "h323-call-type=VOIP" Called-Station-Id = "0873000012" Calling-Station-Id = "0873000001" Acct-Status-Type = Start Acct-Session-Id = "b97aff16 c99911dd 8125d127 98296413 " Event-Timestamp = "Dec 15 2008 11:43:21 ICT" NAS-Port-Type = Ethernet then FR should send accounting respond : h323-credit-amount=customer balance at the time of authentication h323-return-code=0(accept)/2(reject) h323-billing-model=2 but FR send: Sending Accounting-Response of id 192 to 172.26.0.8 port 1645 can the FR do that? if yes, where should i edit if i want to send response to NAS i should add the attribute in the attrs.accounting-response : h323-credit-amount=* ANY h323-return-code=* ANY h323-billing-model=* ANY i check the attrs.accounting-reponse: # # Configuration file for the rlm_attr_filter module. # Please see rlm_attr_filter(5) manpage for more information. # # $Id$ # # This configuration file is used to remove almost all of the attributes # From an Accounting-Response message. The RFC's say that an # Accounting-Response packet can contain only a few attributes. # We enforce that here. # DEFAULT Vendor-Specific =* ANY, Message-Authenticator =* ANY, Proxy-State =* ANY, 1 more question: i read the man unlang times but cannot figure out how to use it could you give the example for specific case such as Access Reject/ update the Access Reject/Accept Thanks Ha`

Re: Is it possible to use FreeRADIUS as AAA in a Cellular Network?

Thanks Ranil Santhis and Luis Carlos Toledo for your reply, I have read in the PDSN GUI help that the interface for AAA must be a logic interface, then I looked in the PDSN configuration and I found two PI (logical) interfaces, here the part of PDSN config that I think is AAA related: [conf] # interface Piif3/0/0 ip address 192.168.1.2 255.255.255.255 # interface Rpif3/0/0 ip address 192.168.1.1 255.255.255.255 # a11 enable pcf 192.168.0.200 192.168.1.1 256 skey 1234567891234567 # construct domain huawei domain enable domain AAAclientsig 1 domain address-group huawei 0 0 10.0.0.51 50 domain dns huawei 0 209.145.204.26 bip 209.145.204.20 # charge enable weekday 6 1 weekday 5 0 weekday 4 0 weekday 3 0 weekday 2 0 weekday 1 0 weekday 0 1 # [/conf] - Can please tell me if this is what I need to co nfigure the PDSN with the FreeRADIUS? - What should I start configuring in the FreeRADIUS side? - Also, I was googling and didnt found what A11 is and why we need it here, can please tellme something about that? Thanks again guys.

May the firewall cause the problem? Yes. I've never understood why people put firewalls between critical network services. And *then* configure the firewalls to time out inactive connections. In this case, what's happening is this: - FreeRADIUS asks the Postgresql client library to open a socket to the server. - it does - 10 minutes later, the firewall decides that the TCP connection is unused, and discards all knowledge of it - FreeRADIUS receives a new request, and asks the postgresql client library to do an SQL query. - the postgresql library believes that the connection is still up, and tries to use it. - the firewall discards ALL packets for the connection - the kernel blocks all reads && writes that the postgresql client library tries to do.. - which then blocks FreeRADIUS. In short, configuring the firewall to discard sessions after 10 minutes or so of idle time is bad. *Especially* because the connections between FreeRADIUS && the DB are idle for longer than that. This is *not* a problem with FreeRADIUS. You have configured your firewall so that *it* is blocking the server. Fix your firewall, or remove it. Nothing else will solve the problem. Alan DeKok.

Client library for using CoA
by Padam J Singh 14 Dec '08

14 Dec '08

Hello, Are you aware of any radius client library which also implements CoA/Packet of Disconnect? I have checked radiusclient-ng and its earlier version - they do not contain any such feature. I saw that CoA is on the roadmap for FR (2007 announcement), any work done on it yet? Thanks, Padam -- PGP Id 9EED2E09
