Raspberry Piでネットワーク帯域制御「tcconfig」のインストール方法

Posted at

Pythonのpip ver 23.0からPEP668対応で従来のインストール方法では不具合がある様子です。
当方で動作した方法を紹介します。

動作環境

Raspberry Pi 4 (4GBモデル)

Raspberry Pi OS with desktop 64bit (2023-10-10)

pi@raspberrypi:~ $ python -V
Python 3.11.2

pi@raspberrypi:~ $ pip -V
pip 23.0.1 from /usr/lib/python3/dist-packages/pip (python 3.11)

tcconfigインストール方法

$ sudo apt install pipx
$ pipx install tcconfig
  installed package tcconfig 0.28.0, installed using Python 3.11.2
  These apps are now globally available
    - tcdel
    - tcset
    - tcshow
??  Note: '/home/pi/.local/bin' is not on your PATH environment variable. These apps will not be globally accessible until
    your PATH is updated. Run `pipx ensurepath` to automatically add it, or manually modify your PATH in your shell's config file
    (i.e. ~/.bashrc).
done! ? ?? ?

ユーザーローカル環境にインストールされます。

pi@raspberrypi:~ $ ls .local/bin -l
total 0
lrwxrwxrwx 1 pi pi 49 Dec  4 05:35 tcdel -> /home/pi/.local/pipx/venvs/tcconfig/bin/tcdel
lrwxrwxrwx 1 pi pi 49 Dec  4 05:35 tcset -> /home/pi/.local/pipx/venvs/tcconfig/bin/tcset
lrwxrwxrwx 1 pi pi 50 Dec  4 05:35 tcshow -> /home/pi/.local/pipx/venvs/tcconfig/bin/tcshow

コマンド実行例

設定変更する際にはsudoコマンドで管理者root権限が必要です。

tcshow(設定確認)

pi@raspberrypi:~ $ .local/bin/tcshow eth0
{
    "eth0": {
        "outgoing": {},
        "incoming": {}
    }
}

tcset(設定変更)

pi@raspberrypi:~ $ sudo .local/bin/tcset --device eth0 --delay 10
pi@raspberrypi:~ $ .local/bin/tcshow eth0
{
    "eth0": {
        "outgoing": {
            "protocol=ip": {
                "filter_id": "800::800",
                "delay": "10ms",
                "rate": "1Gbps"
            }
        },
        "incoming": {}
    }
}

tcdel(設定削除)

pi@raspberrypi:~ $ sudo .local/bin/tcdel eth0 -a
[INFO] delete eth0 qdisc
[INFO] no qdisc to delete for the incoming device.
[INFO] delete eth0 ingress qdisc
pi@raspberrypi:~ $ .local/bin/tcshow eth0
{
    "eth0": {
        "outgoing": {},
        "incoming": {}
    }
}
