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 Stanford University StanfordNetDB

Summary • Introduction • What is Stanford NetDB? • Demonstration • How do we use NetDB? • Distribution Stanford University StanfordNetDB

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 Stanford University StanfordNetDB

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. Stanford University StanfordNetDB

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

DHCP • Supports static/dynamic dhcp settings • Supports DHCP options • Updated every 10 min at Stanford Stanford University StanfordNetDB

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 Stanford University StanfordNetDB

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

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) • When possible, limit user’s view to capabilities – e.g. only show authorized grps, address spaces, etc. Stanford University StanfordNetDB

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 Stanford University StanfordNetDB

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 Stanford University StanfordNetDB

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 Stanford University StanfordNetDB

Futures • IPv6 • Ruby Stanford University StanfordNetDB
