How to test the speed of an internet connection?

January 3, 2006

I was experiencing frequent disconnections of my internet link at home. These were very short but long enough to disturb one service I am using. So I decided to check if my internet provider was correct and doing his job correctly.

My first idea was that there must exists free (as in free speech) and simple command-line tools to test the connection speed under GNU/Linux. As I am not a specialist, I tried to find such tools on the internet but didn’t find any (if you have one, please feel free to share it with me). So I decided to write my own set of scripts in Perl.

For the moment, results are somewhat convincing (but the “ping” command does not reflect exactly the connection speed) but they can already be used 🙂

You can find scripts, how to do it and work in progress here.

  1. http://people.ee.ethz.ch/~oetiker/webtools/smokeping/ – a very nice free software for monitoring network connectivity. Plugins are very easy to write to extend to some other customized services. The author is the author of rrdtool.

  2. Thanks, Alexandre, for the link. SmokePing is obviously much more powerfull than what I wrote: works like a daemon process, use of CGI, use of RRDtool, “smart” alarms, support of dynamic IP, plugins, … It was not my initial goal when I started my script: I just wanted something simple the regular user can launch and stop at will. But, of course, I *need* to install SmokePing in order to check my connection 🙂
