Такая проблема, нужно создать сервер с двумя сетями, условно: 192.168.1.0 и 192.168.2.0. Соответственно в первую сеть будут попадать клиенты с Ubuntu, а во вторую сеть клиенты с Windows. Я сделал такое разграничение с помощью опции 60 (vendor-class-identifier), которую клиенты отправляют на сервер, когда хотят получить адрес. Чтобы убунту отправляла опцию 60 я вроде как сделал, смотрел дамп, да, действительно отправляет свой vendor-class. Настроил DHCP-сервер, но почему-то клиентам на винде адреса раздаются, а клиентам на убунте почему-то нет. Сервер при перезапуске, когда показывает логи пишет примерно такое: DHCPDISCOVER from далее MAC-адрес via ens33: network 224-29: no free leases. В чем может быть ошибка? В общем, приложу ниже файл dhcpd.conf и сами логи. Файл dhcpd.conf:
# dhcpd.conf
#
# Sample configuration file for ISC dhcpd
#
# Attention: If /etc/ltsp/dhcpd.conf exists, that will be used as
# configuration file instead of this file.

# option definitions common to all supported networks...

# The ddns-updates-style parameter controls whether or not the server will
