This are methods you can use to measure the Internet bandwidth, speed, delay etc.. in Linux terminal:
Speedtest.net
sudo apt-get install python-pip pip install speedtest-cli
or:
sudo apt-get install python-setuptools easy_install speedtest-cli
This 2nd solution worked on AWS Ubuntu 13.04 Server and it needed ~3Mb (python-setuptools) to download versus ~80Mb for python-pip
Wget
wget --output-document=/dev/null http://speedtest.wdc01.softlayer.com/downloads/test500.zip
iperf
This measures the bandwidth between two locations where one is set as a server and another as a client.
Start up server listening on port 8888. By default it is TCP port 5001 and TCP window size 64.0KB.
/opt/systems/bin/iperf -s -p 8888
Connect client to server on port 8888
/opt/systems/bin/iperf -c your.server.com -l 1300 -p 8888 -P 10
Switches:
- -t option used in the above command tells to transfer data for X seconds
- -p will tell the client to connect the port 8888 on the server
- -w will specify your desired window size value
- -u options needs to be also used on the client side for specifying UDP traffic in case server
iperf -s -u
was used - -P divide results into X time frames aka lines printed
- -f m displays results in megabytes
