Stanford University StanfordNetDB Stanford NetDB- An Open Source Network Management Application for DNS, DHCP, IP Address Spaces, etc. Sunia Yang Rob Riepel

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. A Name 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)
