I usually start PostAuthHook like this:

sub timelimit_hook {
    my $p = ${$_[0]};      # Request packet
    my $rp = ${$_[1]};     # Response packet
    my $result = $_[2];    # Verdict: success or not
    my $reason = $_[3];    # String that tells reason for a reject

To add to reply, I would do $rp->add_attr('Delegated-IPv6-Prefix',
"<PREFIX>/48");

Calling via $cfg::rp is possible if the code is structured to support
this, but it's impossible to say if it is correct without seeing the
hook code.

To see more messages, usually logged to stderr not Radiator log, try
running Radiator with '-trace 4 -log_stdout -foreground' options. I
usually debug with something like this:

% perl ~/radiator/Radiator-4.9/radiusd -I ~/radiator/Radiator-4.9
-dictionary ~/radiator/Radiator-4.9/dictionary -trace 4 -log_stdout
-foreground -config radius.cfg

Seeing stderr output should tell where it goes wrong. Please let us know
of your findings.

4.9 should work. You do need Socket6.pm installed, but would receive a
log message instead of Radiator crashing if it is not there.

Thanks!
