Ludovic!

I am so glad to hear from you!  Thank you for taking the time to respond.

I am getting the dependency issue when I include perl-Net-DNS in my yum update.

--------<snip>----------
Error: Package: packetfence-4.0.5-2.el6.noarch (@PacketFence)
           Requires: perl(Net::DNS) = 0.65-4
           Removing: perl-Net-DNS-0.65-4.el6.x86_64 (@base)
               perl(Net::DNS) = 0.65
           Updated By: perl-Net-DNS-0.66-1.of.el6.x86_64 (of)
               perl(Net::DNS) = 0.66
 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest
--------</snip>---------

So I'm looking into that.  However I found something interesting.  One of my 
registration clients is sending a strange DNS query and every time pfdns sees 
it, it crashes.

The query is exactly:

ng="utf-8".umhb.edu

I blocked that IP from sending queries to PF and the service hasn't crashed 
since.

I have tried to send this query to my test server to see if I can replicate the 
behavior but I need to edit the pcap to make it go to the test server.

I can send you a link to DL the pcap if you are interested in looking at it.

Also, any idea on the dependency issue is most welcome too : )

Thank you again.

Upgrade perl net dns to the latest version from our repo.

Fellow PF users, I am in need of your assistance!

My production PF box is having the pfdns service crash every few seconds.

I am working on getting some pcaps to see if it is network based but I cannot 
find anything on the logs. It seems to be failing completely silently.

I would appreciate any assistance you ca
 n
offer.
