[RADIATOR] radpwtst - sending multiple packets

[Michael]

Sounds good.  i'll check out that module.  What I was trying to do is 
log what I call a 'checkpoint' for all online sessions for the purpose 
of calculating monthly bandwidth usage.  if a session starts in one 
month, but logs out in a different month, you can't calculate the 
monthly usage accurately.  I wanted to log a checkpoint entry containing 
the usage on the 1st of every month for each session.  with that, usage 
can be subtracted to find the usage of that month.

So, i ended up using 'Alive' packets to accomplish this. Seems like kind 
of a hack, but it works pretty good.

<Client ...>
...
# for a 40 minute windows on the 1st of every month, set 
Acct-Status-Type = checkpoint
ClientHook sub { my $req = ${$_[0]}; \
     my $dHM = &Radius::Util::format_special("%d,%H,%M");
     my( $d, $H, $M ) = ( split(/,/,$dHM) )[0,1,2];
     if( $d == 1 && $H == 0 && $M <= 40 && 
$req->get_attr('Acct-Status-Type') eq 'Alive' ) {
&main::log($main::LOG_WARNING, "ClientHook: 1st of the month. 
configuring Alive packet as a checkpoint.");
       $req->change_attr('Acct-Status-Type','checkpoint');
     }
...
</Client>

And then later, in an AuthBy:

<AuthBy SQL>
...
# for Acct-Status-Type = checkpoint
         HandleAcctStatusTypes   checkpoint
         AcctSQLStatement INSERT INTO some_table ( sess_id, timestamp, 
upload, download, ..... ) \
                         VALUES ( '%{Acct-Session-Id}', %b, ... ) \
                         ON DUPLICATE KEY UPDATE (x=y,xx=yy, ....)

...
</AuthBy>
