• sudo yum install -y epel-release
  sudo yum install -y speedtest-cli

• Run Speed Test:
  After installation, you can simply run:

2. speedtest

   • This will automatically find the nearest server and perform a speed test, providing you with download and upload speeds along with ping.

Option B: Using iperf

iperf is another tool that can measure the bandwidth between two hosts on a network.

1. Install iperf:

• sudo yum install -y iperf

• Choose a Testing Server:
  You need a server that you can connect to for the test. You can use public iperf servers available online. For this example, let's use iperf.org for testing.

• Run the Client:
  Start an iperf test without needing a server on your VPS:

  iperf -c iperf.umd.edu

1. Review the Results:
   The output will display transfer speeds in Mbps along with other information.

Additional Tools

If you want a graphical representation, consider using the nload or iftop commands to monitor network usage.

1. Install nload:

sudo yum install -y nload

Then run:

• nload

• Install iftop:

sudo yum install -y iftop

Run it with:

2. sudo iftop

You have successfully checked your internet speed on a CentOS VPS using two different tools: speedtest-cli and iperf. Use the one that fits your needs better.
