How to parse the "value" in an accounting message and print the contents In "detail-..." file?
Hello, I am trying to decode accounting message from a device which sends PacketCable Event Messages. These are VSAs and the payload has a custom format. Freeradius dumps the octet string of the length of the message which it cannot decode (due to custom format) I want to dump these specific attributes in the message. How do I go about doing that? I want to dump the output in the "detail-..." file along with the other attributes. I am using freeradius version 1.1.7 (built March 10, 2008) on ubuntu with linux kernel 2.6.26-19 Thank You. -a
Freeradius has cablelabs VSA dictionary. If it needs updating ask the vendor for the latest dictionary. Post it also to this list so that it can be included in the distribution. Ivan Kalik Kalik Informatika ISP Dana 8/12/2008, "al pat" <alps.oss@gmail.com> piše:

Ivan, Yes, there is a cablelabs dictionary. The problem is that one of the attributes has a complex structure that is embedded in the value part. The value part here is just printed as a hex string - but from the packetcable standard it is to be interpreted in a certain way. Since this payload itself has specific meaning in the context of packetcable, some intervention will be needed to print that - just don't know yet how to go about doing it. -a 2008/12/8 <tnt@kalik.net>

OK I get it. So your attribute *is* an octet string.
Both the instances of "Cablelabs-Event-Message" should translate to things like
Version-ID (4 bytes), BCID (24 bytes), Signaling_Start, ...
You will have to do the translation yourself. You can use perl module and store the result in a self defined attribute (have a look at raddb/dictionary) and use linelog to print it out. Ivan Kalik Kalik Informatika ISP
Hi Ivan, Hmm, on my ubuntu system - I am not able to execute a basic perl module from freeradius. It is freeradius version 1.1.7 (installed using apt-get install freeradius) When i start freeradius with -X option, I am not seeing any indication of rlm_perl being loaded. (I have included a perl {} section under modules in radiusd.conf, as well as tried including the experimental.conf file which has perl module definition). Any inputs with this?

Build 2.1.3 from source. Or build a debian package. Ensure that you install libperl-dev, too. Alan DeKok.
