5 Disabling MPTCP

To disable MPTCP:

  1. Disable MPTCP at runtime, by running the following command:
    sudo sysctl -w net.mptcp.enabled=0

    The output shows that MPTCP is disabled:

    net.mptcp.enabled = 0
  2. (Optional) If you added net.mptcp.enabled=1 to /etc/sysctl.conf, remove or comment out the line.
  3. Reload the sysctl settings, by running the following command:
    sudo sysctl --system
  4. Confirm that MPTCP remains disabled, by running the following command:
    sysctl net.mptcp.enabled

    If MPTCP has been successfully disabled, the command returns the following:

    net.mptcp.enabled = 0
