I need to be able to proxy accounting requests that arrive with no User-Name attribute. Is that possible? I haven't been able to make it work. Maybe I could insert a dummy User-Name pre-proxy and remove it post-proxy? Also, I notice that when running in -X mode, the accounting-response is not relayed to the original client. Works fine when not in -X mode. Here's a debug of a scenario where an accounting-request was proxied correctly; yet, the accounting-response is not relayed to the client by the proxy server: rad_recv: Accounting-Request packet from host 152.2.199.26 port 32823, id=155, length=86 User-Name = "jcc" NAS-Port = 5060 Sip-Src-IP = 152.2.199.26 Acct-Status-Type = Start Sip-Transport-Proto = TLS Acct-Session-Id = "accounting-session-1-id" Processing the preacct section of radiusd.conf modcall: entering group preacct for request 4 rlm_acct_unique: WARNING: Attribute Client-IP-Address was not found in request, unique ID MAY be inconsistent rlm_acct_unique: Hashing 'NAS-Port = 5060,,NAS-IP-Address = 152.2.199.26,Acct-Session-Id = "accounting-session-1-id",User-Name = "jcc"' rlm_acct_unique: Acct-Unique-Session-ID = "7910d35136b9eb7a". rlm_realm: No '@' in User-Name = "jcc", looking up realm NULL rlm_realm: Found realm "NULL" rlm_realm: Proxying request from user jcc to realm NULL rlm_realm: Adding Realm = "NULL" rlm_realm: Preparing to proxy accounting request to realm "NULL" modcall: group preacct returns noop for request 4 Processing the accounting section of radiusd.conf modcall: entering group accounting for request 4 radius_xlat: '/usr/local/var/log/radius/radacct/152.2.199.26/detail-20061114' rlm_detail: /usr/local/var/log/radius/radacct/%{Client-IP-Address}/detail-%Y%m%d expands to /usr/local/var/log/radius/radacct/152.2.199.26/detail-20061114 radius_xlat: 'Tue Nov 14 12:15:11 2006' rlm_detail: Freeradius-Proxied-To set to 152.23.129.213 radius_xlat: '/usr/local/var/log/radius/radutmp' radius_xlat: 'jcc' modcall: group accounting returns ok for request 4 Sending Accounting-Request of id 227 to 152.23.129.213 port 1815 User-Name = "jcc" NAS-Port = 5060 Sip-Src-IP = 152.2.199.26 Acct-Status-Type = Start Sip-Transport-Proto = TLS Acct-Session-Id = "accounting-session-1-id" NAS-IP-Address = 152.2.199.26 Proxy-State = 0x313535 --- Walking the entire request list --- Cleaning up request 4 ID 155 with timestamp 4559f99f Nothing to do.
