Organizing Your DNS?

Neil Watson asks: "In previous organizations I've kept track of IPs, hostnames and DNS entries by using a single hosts file. I used a script (h2n) to convert the hosts file to DNS entries (BIND). Thus, all information was available in a single text file. For Microsoft Active Directory servers, we had that system's DNS server simply forward all of its requests to the BIND server. Now, I find myself at another organization. This network is considerably larger, with more name servers. The control of IPs, hostnames and DNS entries is somewhat loose, and it is starting take its toll. How do you organize all of your DNS information in order to easily assign and track all of the entries?"

You can use PowerDNS and any number of administrative tools to manage the domains with a SQL database rather than flat text files.

Ganymede, Doctor DNS

[jonabbey]

We have been using our own software, Ganymede, to handle our DNS for the last 7 years. Ganymede is a programmable directory mastering application.. you give it a schema with objects for real-world items such as systems, interfaces, networks, etc., and Ganymede provides an object database and concurrent client/server GUI for making changes. Whenever an administrator hits 'commit' in their client, Ganymede turns around and updates the DNS (and in our case, our NIS, our Active Directory, our DHCP, and more) on a background thread.

The schema we use for managing DNS at ARL:UT is not the most flexible, in that we have only a single DNS domain that we are managing, and may well not fit your environment, however there is a consulting company in Germany, http://www.fg-networking.de/, which has built a complete DNS and DHCP management solution around Ganymede. They are using it to manage the DNS and DHCP for a University of 14,000 hosts, and they might be able to help you out with your environment.

If you do decide you might like to know more about Ganymede, let me know.. I've been working on it for the last couple of years for internal use and for clients, without posting any new releases on our website. The software has tons of improvements that have been made in the meantime.

Ganymede 2.0 uses SSL for all client-server communications, as well as digitally signing the applets. It also requires Java 1.4 or better, largely in order to support SSL.

Ganymede supports roles, so that you can give certain administrators arbitrarily reduced privileges. If you've got people who need to have limited privileges as you describe, it's possible to grant them in Ganymede, if the powers that be permit it.

May I ask if you work at ARL:UT?
