Free SNMP Software Suit in Windows Environment - Net-SNMP (Snmpv3 Support)

I was looking for this kind of software for a while. Mostly desktop and servers I am using are windows based. There is no Snmpwalk this kind of command under windows OS. Good things, there are always some genius to see the gap and develop some gorgeous tools to meet the needs from the people like me.

Net-SNMP is one of this kind of software. Based on their website - http://www.net-snmp.org/
"
Net-SNMP is a suite of applications used to implement SNMP v1SNMP v2c and SNMP v3 using both IPv4 and IPv6. The suite includes:
  • Command-line applications to:
    • retrieve information from an SNMP-capable device, either using single requests (snmpgetsnmpgetnext), or multiple requests (snmpwalksnmptablesnmpdelta).
    • manipulate configuration information on an SNMP-capable device (snmpset).
    • retrieve a fixed collection of information from an SNMP-capable device (snmpdfsnmpnetstatsnmpstatus).
    • convert between numerical and textual forms of MIB OIDs, and display MIB content and structure (snmptranslate).
  • A graphical MIB browser (tkmib), using Tk/perl.
  • A daemon application for receiving SNMP notifications (snmptrapd). Selected notifications can be logged (to syslog, the NT Event Log, or a plain text file), forwarded to another SNMP management system, or passed to an external application.
  • An extensible agent for responding to SNMP queries for management information (snmpd). This includes built-in support for a wide range of MIB information modules, and can be extended using dynamically loaded modules, external scripts and commands, and both the SNMP multiplexing (SMUX) and Agent Extensibility (AgentX) protocols.
  • A library for developing new SNMP applications, with both C and perl APIs.

There is a tutorial page at http://www.net-snmp.org/wiki/index.php/Tutorials .

Here I would like to list some usage from my person experience.

Best Free Network Performance Test tool - Iperf

According to wikipedia Iperf "is a commonly used network testing tool that can create TCP and UDP data streams and measure the throughput of a network that is carrying them. Iperf is a modern tool for network performance measurement written in C++." So far it is best free software to test network throughput I found. 

1. Download iperf 2 from http://iperf.fr/.

2. Running on one of your remote machine from command line as iperf server (ip address 100.99.136.66).




C:\Tools>iperf -s
