Re: rlm_perl and accounting

I see the patch you're referring to, but after rethinking my question, I 

think what I'm really trying to do is rewrite $RAD_REQUEST, not 

$RAD_REPLY, and it does not appear that I can alter $RAD_REQUEST in any 

way - either change or add.  If I understand correctly, $RAD_REPLY is 

the hash of attributes that the server will send back to the NAS, and 

$RAD_REQUEST is the hash of attributes that is actually written when the 

detail module is called.  My goal is to inspect the received attributes 

using rlm_perl in the preacct{} phase before they are written to log in 

the accounting{} phase and possibly remove/rewrite/add attributes before 

they are logged.  Is this possible with rlm_perl?

Also, I've observed that the freeradius will not start when my 

example.pl script contains use Data::Dumper;  It looks as if others have 

had this problem when their perl was not compiled with ITHREADS support, 

but my perl does have ITHREADS support, and neither perl -c 

-MData::Dumper nor perl example.pl returns an error.

jcc@black-pearl:~/scripts$ perl -v
This is perl, v5.8.7 built for i486-linux-gnu-thread-multi

jcc@black-pearl:~/scripts$ perl -V | grep ITHREADS
  Compile-time options: MULTIPLICITY USE_ITHREADS USE_LARGE_FILES

Thanks.

Yes, this is due to the way rlm_perl works by default (new pairs can be 

added but existing ones not changed). Look back a week or so in the 

mailing list archives to the problem I was having. There is a patch on 

the list that will allegedly make it into HEAD. The patch works nicely 

for me.
