It is a tool for performing network throughput measurements. It can test either TCP or UDP throughput. To perform an iperf test the user must establish both a server (to discard traffic) and a client (to generate traffic). This page explains how to test the network speed/throughput between two Linux servers.

How to check the connectivity between two servers?

I want to check connectivity between 2 servers (i.e. if ssh will succeed). The main idea is to check the shortest way between server-a and server-b using a list of middle servers (for example if I’m on dev server and I want to connect to prod server – usually a direct ssh will fail).
