bing – Measure Bandwidth from Command Line

By | 2012/08/22

The command line program bing measures bandwidth between two point to point locations. This is an excellent tool for testing throughput or interfaces. Here is how it works!


Install bing:

$ sudo apt-get install bing

The syntax is:

$ sudo bing [host1] [host2]

bing works by sending an ICMP echo request and measuring the delay of the echo reply.

A packet capture of bing in action looks like the following:

20:50:10.671003 IP 172.16.1.202 > 172.16.1.1: ICMP echo request, id 52504, seq 21315, length 52
