Re: Display FQDNs on mouse over
So from what I can tell, this is a DNS issue and not a bug. I've done some testing here and our boxes here and I haven't been able to make this happen in our internal network and all the defined DNS works for our workstations and outside sources that the netflow data records. So when you go to google, you can find google's IP address and hover over it and it shows up with the google server's hostname. This makes me think that the DNS is not set up in a way that the PHP gethostbyaddr function (http://us3.php.net/gethostbyaddr) can look up the hostname based on the IP address alone (doing the actual reverse dns lookup) for whatever reason. Unfortunately this function that gets the hostname wasn't created by us and not a part of network analyzer code and since it's a standard function that comes with PHP we can't do much about the actual functionality. I'm told it works the same as the C gethostbyaddr but I am not 100% sure on that. I'm sorry that we couldn't be more help with this issue!

Re: Display FQDNs on mouse over
sorry it took me so long to respond to this. We were checking everything on our end and found no issues with DNS or anything that would be causing the issue from there. I decided on a whim to move the entries for the DNS servers that the non-working IPs were using to the top of the list in the resolv.conf file and that fixed the issue. I'm guessing that since NNA was able to resolve hostnames on some of the hosts using the first couple of entries in the conf that it just stopped looking at the other entries or something. Not sure if that's intended behavior or not, but either way the issue is resolved now. Thanks for your help!
