My ubuntu server has a 1gbps connection. How can I test this connection via ssh terminal?

Answer 1

For a general command line Internet speed test, you could use speedtest-cli.

One-liner usage:

python3 <(curl -sL https://raw.githubusercontent.com/sivel/speedtest-cli/master/speedtest.py)

^{_{Note: The above command assumes that you trust the Python 3 code retrieved from https://raw.githubusercontent.com/sivel/speedtest-cli/master/speedtest.py.}}

Sample output:

deltik@box1 [~]$ python3 <(curl -sL https://raw.githubusercontent.com/sivel/speedtest-cli/master/speedtest.py) --server 17394

If you want to test the speed between your server and a client that you control, you can use iPerf3.

First, install iPerf3 on both the client and the server. Ubuntu/Debian installation command:

sudo apt install -y iperf3

On the server, run iperf3 in server mode:

iperf3 -s

On the client, run one of these commands to test the speed:

^{_{(Replace XXX.XXX.XXX.XXX with your server's IP address.)}}

• Client to server TCP transfer:

  iperf3 -c XXX.XXX.XXX.XXX
  

• Server to client TCP transfer:

  iperf3 -R -c XXX.XXX.XXX.XXX
