Hello, I have setup made according to robust proxy accounting guide. Now I need freeradius to add Tmp-String-1 attribute to each Access-Request sent to proxy. I tried using policy conf and ulang in robust-proxy-accounting config, but request sent to proxy is still unmodified One of log examples (just for curiosity i'm trying update both - proxy-request and request: (0) server home.mycompany.com { (0) # Executing section pre-proxy from file /etc/freeradius/sites-enabled/robust-proxy-accounting (0) pre-proxy { (0) policy add-attribute { (0) update request { (0) Tmp-String-1 := 1111111 (0) } # update request = noop (0) update proxy-request { (0) Tmp-String-1 := 1111111 (0) } # update proxy-request = noop (0) } # policy add-attribute = noop (0) policy debug_proxy_request { (0) if ("%{debug_attr:proxy-request:}" == '') { (0) Attributes matching "proxy-request:" (0) &proxy-request:User-Name = username (0) &proxy-request:User-Password = password (0) &proxy-request:NAS-Identifier = nasid (0) &proxy-request:Framed-Protocol = PPP (0) &proxy-request:Service-Type = Framed-User (0) &proxy-request:Event-Timestamp = Jun 29 2017 13:51:01 UTC (0) &proxy-request:NAS-IP-Address = 185.7.90.32 (0) &proxy-request:Message-Authenticator := 0x00 (0) &proxy-request:Proxy-State = 0x313636 (0) &proxy-request:Tmp-String-1 := 1111111 (0) EXPAND %{debug_attr:proxy-request:} (0) --> (0) if ("%{debug_attr:proxy-request:}" == '') -> TRUE (0) if ("%{debug_attr:proxy-request:}" == '') { (0) [noop] = noop (0) } # if ("%{debug_attr:proxy-request:}" == '') = noop (0) } # policy debug_proxy_request = noop (0) } # pre-proxy = noop (0) } (0) Proxying request to home server 138.7.90.9 port 1812 timeout 30.000000 (0) Sent Access-Request Id 19 from 0.0.0.0:30848 to 138.7.90.9:1812 length 101 (0) User-Name = "username" (0) User-Password = "password" (0) NAS-Identifier = "nasid" (0) Framed-Protocol = PPP (0) Service-Type = Framed-User (0) Event-Timestamp = "Jun 29 2017 13:51:01 UTC" (0) NAS-IP-Address = 185.7.90.32 (0) Message-Authenticator := 0x00 (0) Proxy-State = 0x313636 Waking up in 0.3 seconds. As you see proxied request is unchaged, while debug output above states attribute was added. For example if in same way I modify existing attribute - this will work fine, i.e Framed-Protocol will be sent to proxy with value I set. update proxy-request { Framed-Protocol := 11111 } But I need new attr added, and now I'm completely out of ideas how to achieve this. Already read lots of mailing archives, unlang doc and etc - still do not understand how attribute can be added. So if someone has any idea - please point me to correct doc/direction. freeradius 3.0.12 -- Denis
