Title: bandwidth speed test from server to client
Post by: mike wainscott on July 30, 2003, 01:19:37 AM

I'd like to set up a speedtest where client machines could access the server to determine what their network access speed to the server is.  Ideally, I'd like to set it up as a web page on the server that is only available to the client machines and not the internet.  This would be helpful in measuring my wireless client speed.

Thanks,
Mike

Hit it with a 1024 byte packet using PING.

Win32:
ping -l 2500 [IP]

Linux:
ping -s 1024 [IP]

Note, if you wanted to be a little more flashy, you could create a PHP script that would ping the REMOTE_ADDR server variable passed through HTTP and then parse that, and generate your speed results.

IE:

Ping > 1024 MS = Bad connection
Ping > 500 MS and Ping < 1024 MS = "Dialup"

Etc.

Thanks for the input Nathan.  I was actually hoping for something 'canned' that
someone had built that ran a more extensive process from the server to the
client and vice-verse so as to display a web page with a nice graphic
indicating upload and download speed.  This would involve more than
just a few pings so as to calculate a short but sustained data rate in both
directions.  
 
Thanks again,
Mike

The problem is testing the Upload speed.  By using PING you're testing round-trip.  You're not going to be able to get a client to upload a file of X bytes unless you are using some type of Java application that can create a socket.  Timing downloads are easy, it's the upload that's difficult.

I'm assuming you're wanting something like http://wdc.speakeasy.net

Yes, that's the general Idea.  I was hoping someone would already have some small script and the HTML to wrap around it for a turnkey app.
