error message from lib/perl5/Lire/Apache.pm

[Wytze van der Raay]

Having installed the lire 20010329 release on nlnet.nl's central server,
I am observing a load of error messages being logged to syslog like this:

Mar 30 12:05:40 bell lire: bogus message: Use of uninitialized value at
/village/wytze/logreport/software/lib/perl5/Lire/Apache.pm line 135, <> chunk
21854.

On inspection of the perl code:

    $domain = join(".",$d[-2],$d[-1]);

and the "offending" logfile lines, it seems that the Apache.pm script
assumes that an alphanumeric string in the hostname field will always be
of the form xxx.subdomain.topdomain. I would like this to be true, but
in practice, our webserver is visited by systems with IP addresses
which resolve to something like "host130-26" after reverse DNS resolution
(which is done on the fly if possible).
Bad DNS setup on the client provider site I guess, outside our control.
But could we get rid of those parsing error messages anyway?
