Neo  -  SNMP Network Management Tool
Neo is an open source network administration tool used extensively at MIT to aid in the tasks of administering the network. Neo uses a simple command line interface to talk to hubs, switches and routers via SNMP. Some of the features of Neo are:
  • As a command line client it can be run over telnet, rlogin or text ssh sessions.
  • It can locate a host on a network device or a collection of network devices.
  • It can enable and disable network ports.
  • It can produce a summary of device layout.
  • It can produce statistics on per-port bandwidth use.
  • It can be used in scripts.
News! A beta version of Neo 2 in Python will soon be available for testing!
