Что интересно dhcpdump, в отличии от tcpdump, офферов не видит

https://www.altlinux.org/Etcnet: Обратите внимание, что ISC DHCP сервер на интерфейсе VLAN, скорее всего, у вас не будет работать, пока вы не добавите опцию VLAN_REORDER_HDR=on в настройки vlan интерфейса. Если это оно, то не баг. Да! Спасибо! Это оно!
Однако вопрос:
man ip-link, говорит о том что reorder_hdr { on | off } - specifies whether ethernet headers are reordered or not (default is on) - по умолчанию реордеринг включен, т.е. получается в пакете etcnet его по умолчанию специально отключают. Для чего был выбран такой подход? Тем более что в других дистрибутивах, к примеру:
Fedora release 34 (Thirty Four)
Slackware 14.2
Значение оставлено по умолчанию.
Тем более что дисрибутив ориентирован на виртуализацию, а получение ip по dhcp для виртуальных машин весьма вероятно. В сизифе исправил. Отправил обновление в p10. Ждемс. * Thu Jul 28 2022 Alexey Shabalin <shaba@altlinux.org> 0.9.26-alt1 - vlan: set default reorder_hdr=on (Closes: #43330). |
Description
Валентин 2022-07-25 00:32:39 MSKСистема: ALT Virtualization Server 10 (Actinoform) Ядра: 5.10.131-std-def-alt1 и 5.10.88-std-def-alt1 dhcpcd 9.4.0 и isc-dhclient-4.4.2 Сисема управления настройками сети Etcnet Проблема касается сабинтерфейсов типа vlan, на родительском интерфейсе работает. dhcp клиент отправляет DHCPDISCOVER, на интерфейсе клиента виден входящий DHCPOFFER от сервера, но DHCPREQUEST не отсылается и через некоторое время цикл повторяется: [root@shaft boot]# tcpdump -vvvepnni eth0 udp tcpdump: listening on eth0, link-type EN10MB (Ethernet), capture size 262144 bytes
