  1. Stanford NetDB- An Open Source Network Management Application for DNS, DHCP, IP Address Spaces, etc. http://stanfordnetdb.stanford.edu Sunia Yang sunia@stanford.edu Rob Riepel riepel@stanford.edu

  2. Summary • Introduction • What is Stanford NetDB? • Demonstration • How do we use NetDB? • Distribution

  3. Introductions • Rob Riepel • NetDB architect • Architect/programmer/keeper for DNS, DHCP • Dmitri Priimak • Programmer for middleware and front end • Sunia Yang • NetDB "user advocate,” tester • Network monitoring • Application bandwidth management

  4. What is Stanford NetDB? • Model of the IP network- 20 years • DNS, DHCP, Whois data source • IP address management • Host information/inventory • Distributed administration • GNU Public License version 2 (2007) Models how humans think of networks.

  5. DNS Name Space • Supports domains/subdomains • Checks all names for uniqueness • Enforces DNS rules • e.g. A Name cannot be MX • Authorization of names by domain • 1 min to generate Stanford zone file • Updated hourly at Stanford

  6. DHCP • Supports static/dynamic dhcp settings • Supports DHCP options • Updated every 10 min at Stanford

  7. IP Address Space Management • Address spaces organized into networks - “network” maps to layer 2 network • Easy to split/join/move address spaces • Authorization by address space • Reserved addresses can only be used by gods • Uniqueness enforced • Automatically looks for next available address

  8. Host Inventory • Nodes show the way humans think of computers • Associates nodes with people/location/dept • Custom fields allow quick extension of database

  9. Distributed Administration • Ease of use allows many users • 900+ at Stanford, 15 minutes of training • Granular authorization • Choice of interfaces • Web - general users • CLI - power users, scripting • API - Dorms for custom interface • Easy import/export (csv)

  22. Servers used at Stanford • Web/middleware • Dell 1850, dual 2.8Ghz, 4GB RAM • Linux Debian • Database • Dell 2650, 4 x 3Ghz, 7GB RAM • Linux Redhat 2.4.21-37.ELsmp

  23. Platform Dependencies • Oracle 10G database • works with Express version • Java 1.6 • Debian Linux • probably works on any Unix with Java 1.6 • Perl DBD::Oracle for reporting

  24. NetDB at Your Site • External pieces required: • Directory provider (e.g. LDAP) • Seed data + sample directory provider included • Web login requires webauth • CLI requires Kerberos • Sample DNS/DHCP generation scripts included

  25. Futures • IPv6
