Names and numbers

We use the DNS to map names to numbers. There is a Bind DNS server running on empire to provide this service to routers, PCs and other devices deployed in the Systems and Networking Lab.

We use numbers from the VUW address range, 130.195.4.128/25 and RFC 1918 - Address Allocation for Private Internets to number devices in the labs as follows:

Description

We are very likely to add more here.

Monitoring and backup tools

Network Laboratory Rancid

Rancid monitors a router's (or more generally a device's) configuration, including software and hardware (cards, serial numbers, etc) and uses CVS (Concurrent Version System) or Subversion to maintain history of changes.

Network Laboratory Munin

Munin the monitoring tool surveys all your computers and remembers what it saw. It presents all the information in graphs through a web interface.

Hugin and Munin are the ravens of the Norse god king Odin. They flew all over Midgard for him, seeing and remembering, and later telling him. "Munin" means "memory".


Network Laboratory Smokeping

Smokeping keeps track of your network latency

Network Laboratory Torrus

Performance testing

Iperf was developed by NLANR/DAST as a modern alternative for measuring maximum TCP and UDP bandwidth performance. Iperf allows the tuning of various parameters and UDP characteristics. Iperf reports bandwidth, delay jitter, datagram loss.
