Работа с приоритетами соединений в Network Manager

Zeta · October 30, 2023, 9:44am

Добрый день!

Изучаю документацию GitHub - wirenboard/wb-nm-helper: Wirenboard network configuration backend for wb-mqtt-confed

Вижу строки:
Если текущее активное соединение не является наиболее приоритетным, сервис с периодом в 60 секунд будет пытаться активировать более приоритетные соединения. При активации более приоритетного соединения, все менее приоритетные закрываются.

Правильно ли понимаю, что при отсутствии приоритетного подключения контроллер будет каждые 60 секунд отключать текущее менее приоритетное подключение в попытке перейти на более приоритетное?
Более логичным выглядит проверка в фоне, чтобы отсутствие приоритетного подключения не вызвывало сбои при проверке доступа.

Еще один вопрос.

На контроллере файл /etc/wb-connection-manager.conf в таком формате:


{
  "connectivity_check_url": "http://network-test.debian.org/nm",
  "tiers": {
    "high": [
      "wb-gsm-sim1"
    ],
    "low": [],
    "medium": [
      "wb-eth1",
      "wb-eth0"
    ]
  }
}

А в документации:

{
    // Включение/выключение отладочных сообщений
    "debug": false,

    // Список названий соединений от в порядке убывания приоритета
    "connections": [
        "wb-eth1",
        "wb-gsm-sim1",
        "wb-gsm-sim2"
    ]
}

Какой формат более актуальный?

Так же вижу, что можно указать “wb-gsm-sim1” и “wb-gsm-sim2”. Сервис будет автоматически переключать SIM при отсутствии интернета на текущей SIM? Используются ли при этом метрики качества сигнала или только простая проверка по http://network-test.debian.org/nm?

Добрый день.

Не верно. Здесь речь идет не об отключении соединения, а о переключении на наиболее приоритетное соединение с доступом в интернет и направлении интернет-трафик через него. По факту контроллер не отключает менее приоритетное подключение (кроме модема).

Актуальной является версия конфига с контроллера.

mikhail.burchu · October 31, 2023, 7:43am

Верно. В таком случае, если будет отсутствовать интернет на одном активном gsm-соединении, то контроллер попробует подключиться через другое gsm-соединение.

Я думаю, что такое невозможно, т.к. одновременно модем может работать только с одной SIM-картой.

Zeta · October 31, 2023, 8:02am

Спасибо!

По поводу метрик GSM.
Вполне вероятен случай, когда на обоих SIM интернет есть, но на первой, скажем, 4G, а на второй 2G и слабый сигнал. Я думаю можно в процессе работы сим запоминать среднее качество сигнала и использовать это в качестве приоритетов SIM.

BrainRoot · October 31, 2023, 9:40am

Вот это - да, можно, но (сейчас) динамическое управление приоритетеми не реализовано, к сожалению.
Сейчас в работе задача по добавлению выбора поведения ppp при переключении с него на более приоритетный, отключать/не отключать.

Zeta · October 31, 2023, 11:33am

Подприоритеты внутри medium, low и high в порядке массива?
В случае обрыва первого происходит переключение на второе без попыток переключиться обратно (конечно, если на втором сеть доступна)?

BrainRoot · October 31, 2023, 12:09pm

Да, чтобы пытался переключиться - нужно в разные приоритеты.

Zeta · October 31, 2023, 5:06pm

Чтобы сконфигурировать всё из терминала, достаточно ли выполнить:


# Для wifi
nmcli connection add type wifi con-name "$con_name" ifname wlan0 ssid "$ssid"
nmcli connection modify "$con_name" wifi-sec.key-mgmt wpa-psk
nmcli connection modify "$con_name" wifi-sec.psk "$password"

# Для Ethernet
nmcli connection add type ethernet con-name "$con_name" ifname eth0

# Для GSM
nmcli connection add type gsm con-name "$con_name" ifname "*"
nmcli connection modify "$con_name" gsm.auto-config true
nmcli connection modify "$con_name" ipv4.method auto
nmcli connection modify "$con_name" ipv6.addr-gen-mode default
nmcli connection modify "$con_name" ipv6.method auto

И обновить /etc/wb-connection-manager.conf в соответствии с названиями соединений?

Или лучше использовать wb инструмент для настройки сети?

@BrainRoot, добрый день!
Можно ли указать запасные connectivity_check_url ?

BrainRoot · November 1, 2023, 10:57am

Совсем нет.
То есть можно и так и так, естественно.
Результат - будет один.

Сейчас - нет, так как параметр на вход принимается один.

Добрый день!

Столкнулся с такой проблемой:

Контроллер не мог подключиться к WiFi точке доступа, но после перезапуска NetworkManager, соединение установилось.

BrainRoot · November 3, 2023, 7:01am

Я верно понимаю что перезапуск - в Nov 02 11:20:13?
Какой-то из интерфейсов в режиме клиента, но за 26 минут не подключился, получается? А логи раньше, с момента запуска есть?

Zeta · November 3, 2023, 7:48am

В процессе отладки заметил, что /etc/wb-connection-manager.conf выглядел приверно вот так:

{
  "connectivity_check_url": "http://network-test.debian.org/nm",
  "tiers": {
    "high": [
      "ServiceAP"
    ],
    "low": [],
    "medium": []
  },
  "connections": []
}

Возможно была проблема из-за наличия “connections” (использую последний доступный образ 2307). Добавил в свой скрипт удаление ключа “connections”, тестирую.

Zeta · November 3, 2023, 11:01am

Сейчас проблема с WiFi не воспроизводится, выглядит ок.

Можно ли так перенастроить, чтобы менее приоритетные соединения не закрывались? Хотелось бы более быстрого переключения между eth, wifi и gsm. При этом сразу видеть, что сеть по GSM доступна в процессее настройки контроллера по WiFi или eth.

Zeta · November 3, 2023, 11:06am

Пожалуйста обновите README.md

Тут старая инструкция по работе с приоритетами. Путает.

Zeta · November 3, 2023, 11:15am

Проводим тест с блокировкой сети нп eth, ожидаем, что контроллер переключится на GSM, что он и сделал, судя по логам, но интернет не появился:

UPD2:
@BrainRoot
В итоге похоже на багу. Как воспроизвести:
Исходные данные:
На контроллере настроен GSM, сим карта только во втором слоте, приоритет low. Есть eth и wifi с приоритетом high. WiFi не доступен.
Шаги:

Подключаю eth, дожидаюсь переключения на eth.
Блокирую доступ в интернет через настройки роутера.
Контроллер переключается на SIM, но из resolv.conf не удаляется IP роутера.

Можете попробовать у себя воспроизвести?

BrainRoot · November 7, 2023, 10:54am

Записал для интерфейсов явно статические адреса DNS.

Убеждаюсь что используется именно они, при активном интерфейсе:

cat /etc/resolv.conf
# Generated by NetworkManager
nameserver 10.0.0.33

И, к сожалению, на модем не переключается - что-то с симкартой. Проверю завтра, как поменяю ее.

Zeta · November 7, 2023, 3:39pm

Я кстати статический DNS на контроллере не прописывал. Он видимо выдается роутером.

Zeta · November 8, 2023, 4:14pm

Подскажите, получилось воспроизвести?

BrainRoot · November 8, 2023, 4:28pm

Нет, еще нет подходящей SIM, но помню, завтра должны привезти.
