CLI speed test

linuxbird · 11-03-2010, 04:22 PM

Is there a CLI speed test that I can run in a script?

I'm trying to identify when WAN bandwidth is compromised. I don't want to run this continuously, but would like something that I can put in a script for testing purposes. All the speed tests I've found, while quite adequate otherwise, utilize a GUI interface.

Similarly, is there a linux-based client / server pair that I can use to test out LAN /VLAN issues?

Thanks.

iperf ?

Downloaded it, and at first blush it is what I need for the LAN.

Is there any kind of a CLI WAN performance (ISP speed test)?

http://www.speedtest.net ? ..

.. not cli I know, but you'd need a hosted server to provide the other end

I tend to use the speakeasy one. But there might be one without a GUI and a CLI entry. I suppose I could script the GUI, but it's not straightforward.

How about wget or ftp ?

Kind regards

That's a good option, and I kind of look at those numbers now, but they are highly dependent on not only the network, but the host, and any (unknown) policies that the host may have.

If anyone knows of a way to invoke an ISP speed test from a CLI, I remain interested.

There once was something named tcpspray but it's availability (and support) is now limited...

here are some rpms that might work for you:

The best way for a speedtest is the ftpserver from your provider.

Kind regards

Another one called bing -- uses icmp

Thank much for all the pointers !!!

I'm good, but I won't close this thread out for a couple more days, in case there continue to be some more good suggestions.

what is usually adviced is downloading large files from fast servers. usually they are called 10mb.bin/100mb.bin/1000mb.bin you can then use wget to get them, try:
wget http://speedtest.onsbrabantnet.nl/files/1024MByte.bin for example

I ended up using the download of the large file from the .nl ISP. It gave me a sort-of metric. Not exactly what I was looking for, but usable.

Someday if I have time, I'll write something like that. No need to read large files, one could simply send a string of pseudorandom numbers.

you mean setting up an Iperf server?
