Bug #4195 for Net-DNS: Nameserver.pm

Thu Oct 23 03:59:07 2003 Guest - Ticket created

Subject:

Nameserver.pm

Hi, I've used Net-DNS to make a fast coded and simple Server that gives fake answer depending on who has done the query. Now I found out that in the Nameserver.pm a check for $query existance has made in the make_reply method, (honestly I do not why an empty $query should come) but after jumping in the "invalid packet" portion of the condition it tries to build up the reply; but the strange thing is that it tries to build it up by using the $query and of course it dies saying "Can't call method "header" on an undefined value /usr/local/lib/perl5/site_perl/5.8.0/Net/DNS/Nameserver.pm line 170" just because the $query does not exist. Tx

Maybe the Net::DNSServer module might be easier to do this. It is just a wrapper around Net::DNS using Net::Server which has hooks to allow what you are trying to do. -- Rob On Thu, 23 Oct 2003, Guest via RT wrote: Show quoted text

This will be fixed in the next CPAN release of Net::DNS. -- Chris Reinhardt ctriv@dyndns.org Systems Architect Dynamic DNS Network Services http://www.dyndns.org/
