I'm looking for a tool that will test my internet connection bandwidth and create an simple report like speedtest does.

Do you know some program/tool that do this? Something with CentOS packages would be nice.

ttcp is a simple, possibly too simple, speed test utility.

pchar is another one people cite a lot, I've had bad luck with it, personally.

Here's how I'd use ttcp. You need two machines, each with ttcp (http://playground.sun.com/pub/tcp-impl/ttcp/ttcp.c) compiled on them.

HostA % ./ttcp -r -s -p 9401 
...

HostB % ./ttcp -s -p 9401 < /boot/vmlinuz

Once you've figured out how to get it to run, try different length files to see how speed varies. Use UDP (-u flag on both reader and sender command line) for even more fun!

can you give me an example how to use ttcp? –  Wolfy Jun 27 '11 at 16:25
    
If I don't have 2 machines? –  Wolfy Jun 27 '11 at 17:04
    
If you don't have two machines, ttcp is worthless. It just sends a specified number of bytes over TCP or UDP as fast as it cam, and reports how long it took. Too simple, like I wrote above. –  Bruce Ediger Jun 27 '11 at 17:20

You might be interested in TeSpeed. It is described as:

If you are looking for tool that is able to test internet connection speed fron Linux terminal, you have found it! :) TeSpeed uses speedtest.net servers to check upload and download rate and it puts that information on charts.

I try it, but it doesn't work... –  Wolfy Jun 27 '11 at 19:53

@wolfy, can you give me some more details? error messages perhaps... –  jonyamo Jun 27 '11 at 21:12
    
when I run it, it only print that it starts testing and quit... no error, no info... maybe something in code is missing... I corrected the full path to speedtest.php, but this doesn't helped... –  Wolfy Jun 28 '11 at 12:42

sounds like it might be dying when it attempts to run curl_init. run "php -m | grep curl" to make sure you have the curl module installed and if not that would be your problem. –  jonyamo Jun 28 '11 at 14:47
    
I will try and let you know :) –  Wolfy Jun 29 '11 at 6:12

I'm just repeating the answers listed on this (deleted?) stackoverflow question: http://stackoverflow.com/questions/426272/how-to-test-internet-connection-speed-from-command-line

k2z:

wget --output-document=/dev/null http://speedtest.wdc01.softlayer.com/downloads/test500.zip

or

git clone https://github.com/sivel/speedtest-cli
cd speedtest-cli 
python2.7 speedtest-cli

then you have the exact style results from speedtest.net with cli.

petermolnar:

You could use iperf to test the speed between two machines, since 'iperf' was designed to measure bandwidth.

on machine1 (host, this one will receive)

iperf -s -p 65000

on machine2 (client, this one will upload)

iperf -c [ip of server] -p 65000

Reverse the machines to test the other way (upload->download or vice versa).

billcarroll:

It looks like there is a tool available on sourceforge that uses speedtest.net from the terminal.

Terminal speedtest: http://sourceforge.net/projects/tespeed/

Very basic, but I use a simple shellscript to download a 10MB file from my provider or nearby FTP-server:

#!/bin/sh

wget ftp://ftp.xs4all.nl/pub/test/10mb.bin ; rm 10mb.bin
## debian.unnet.nl is down...
#wget http://debian.unnet.nl/speedtest/10mb.bin ; rm 10mb.bin
#curl -LO http://debian.unnet.nl/speedtest/10mb.bin ; rm 10mb.bin

The output will look like this:

($:~)-> speedcheck.sh 
--2011-06-27 23:36:21--  ftp://ftp.xs4all.nl/pub/test/10mb.bin
           => `10mb.bin'

Use wget or curl as shown in the script according to your wishes and try to find a server more close to your region (Slovenia). Most are in NL, but maybe .IT will fit your needs: http://www.filewatcher.com/m/10mb.bin.10485760.0.0.html

Thanks for this. Do you know how can I measure my upload? –  Wolfy Jun 28 '11 at 7:28
    
Try using cURL. Look into the cURL manpage under uploading: cs.sunysb.edu/documentation/curl/index.html and improve / enhance the above script yourself ;-) –  Henk Jun 28 '11 at 7:49

speed testing an internet connection or between two endpoints depends on several factors. Like the window size,jitter,unordered delivery etc. Refer: Internet Speed test through Command line.

This would be considered as link only answer. Add more elaborative info from the link to your answer. –  mtk Feb 5 '13 at 7:49

I recommend the speedtest-cli tool for this. I created a blog post (Measure Internet Connection Speed from the Linux Command Line) that goes into detail of downloading, installing and usage of it.

Install Git (APT)

$ sudo apt-get install git-core

Install Git (YUM)

$ sudo yum install git

Clone the Repository from GitHub

$ git clone https://github.com/sivel/speedtest-cli.git

Sample Usage and Output

$ ./speedtest-cli
Retrieving speedtest.net configuration...
Retrieving speedtest.net server list...
Testing from Comcast Cable (x.x.x.x)...

Offtopic, but if somebody has no git installed, wget https://github.com/sivel/speedtest-cli/archive/master.zip seems easier then installing git just to clone. –  manatwork Mar 19 '13 at 9:07
