Hi Freeradius list :-) I am have a bit of an issue with the stripping hex values from my ADSL-Agent-Remote-ID field in my Auth packet. I am using an Alcatel-Lucent 7750SR platform and for some reason they decided when converting a DHCPv6 packet into a radius packet it appends the Enterprise ID (which is a hex number) into the ADSL-Agent-Remote-ID. I end up with a packet looking like this: User-Name = "MDR-POLT01 eth 1/1/01/01/4/1/1:10" User-Password = "" NAS-IP-Address = 60.xxx.xxx.xxx ADSL-Agent-Circuit-Id = "MDR-POLT01 eth 1/1/01/01/4/1/1:10" ADSL-Agent-Remote-Id = "\000\000\000\001CHORUS1234567894" NAS-Port-Type = Ethernet NAS-Port-Id = "pw-2:1101.104" Calling-Station-Id = "\000\000\000\001CHORUS1234567894" NAS-Identifier = "bng" Acct-Session-Id = "E1F15900F37E74538D434C" The issue I seem to be running into, since \000 is a termination value, that freeradius sees the value of attribute ADSL-Agent-Remote-Id as blank. Example below. [sql] expand: %{Orcon-User-Name} -> : User-Name = "MDR-POLT01 eth 1/1/01/01/4/1/1:10" User-Password = "" NAS-IP-Address = 60.xx.xx.xx ADSL-Agent-Circuit-Id = "MDR-POLT01 eth 1/1/01/01/4/1/1:10" ADSL-Agent-Remote-Id = "\000\000\000\001CHORUS1234567894" NAS-Port-Type = Ethernet NAS-Port-Id = "pw-2:1101.104" Calling-Station-Id = "\000\000\000\001CHORUS1234567894" NAS-Identifier = "bng1" Acct-Session-Id = "E1F15900F40272538D8D8E" +- entering group authorize {...} ++[preprocess] returns ok [suffix] No '@' in User-Name = "MDR-POLT01 eth 1/1/01/01/4/1/1:10", looking up realm NULL [suffix] No such realm "NULL" ++[suffix] returns noop [files] expand: %{ADSL-Agent-Circuit-Id} -> MDR-POLT01 eth 1/1/01/01/4/1/1:10 ++[files] returns noop [sane_dhcpv6_chorus] expand: \000\000\000\001 -> \000\000\000\001 sane_dhcpv6_chorus: Does not match: ADSL-Agent-Remote-Id = sane_dhcpv6_chorus: Could not find value pair for attribute ADSL-Agent-Remote-Id ++[sane_dhcpv6_chorus] returns ok My attr_rewrite code is: attr_rewrite sane_dhcpv6_chorus { attribute = ADSL-Agent-Remote-Id searchin = packet searchfor = "\\000\\000\\000\\001" replacewith = "" ignore_case = no new_attribute = no max_matches = 10 ## If set to yes then the replace string will be ## appended to the original string append = no } I have raised the issue with the vendor, but I am not holding my breath for a fix anytime soon. Are there any other options in freeradius to get around this?
