Roberto,
we have a wireless controller that sends MAC addresses in this format:
20-5e-aa-33-18-2f
It does so for the client (Calling-Station) MAC as well as that of the WAP
being used (Called-Station).
To get these addresses to match the format used by other systems I use the
following method.
In the main Radiator config file there is the following hook:
…
# Rewrite Cisco-style '20-5e-aa-33-18-2f' to common '20:5e:aa:33:18:2f'
#
PreClientHook file:"/usr/local/etc/radiator/hook-files/RewriteMAC.pl"
…
The hook-file itself looks like this
# Rewrite MAC addresses
#
# The cisco Wireless Controllers use dashes (-) for MAC addresses in
# the Radius requests.
# For analyses purposes they are rewritten to more commen colons (:).
sub
{
my $p = ${$_[0]};
my $clientmac;
my $wapmac;
if ($clientmac = $p->get_attr('Calling-Station-Id'))
{
&main::log($main::LOG_DEBUG,
"Calling-Station-Id = $clientmac");
$clientmac =~ tr/-/:/;
$p->change_attr('Calling-Station-Id', $clientmac);
}
if ($wapmac = $p->get_attr('Called-Station-Id'))
{
&main::log($main::LOG_DEBUG,
"Called-Station-Id = $wapmac");
$wapmac =~ tr/-/:/;
$p->change_attr('Called-Station-Id', $wapmac);
}
return;
}
A proper Perl coder could do a better job, but for us, this gets the job done.
As your starting format differs, you will have to change the two actual
rewrites; they probably should look something like this:
$clientmac =~
s/^([a-f0-9]{2})([a-f0-9]{2}:[a-f0-9]{2})([a-f0-9]{2}:[a-f0-9]{2})([a-f0-9]{2})$/$1:$2:$3:$4/;
and
$wapmac =~
s/^([a-f0-9]{2})([a-f0-9]{2}:[a-f0-9]{2})([a-f0-9]{2}:[a-f0-9]{2})([a-f0-9]{2})$/$1:$2:$3:$4/;
Hope this can help getting to where you want!
