SSH и связывают медленный подъем после начальной загрузки. Ошибочная сеть перезапуска

Я создаю маршрутизатор с помощью 16.04.2. После установки SSH, переименовывая/устанавливая интерфейсы, затем устанавливающие, Связывают, я заметил, что требуется приблизительно 5 минут для ssh, и свяжите, чтобы начать отвечать (ICMP начинает отвечать в течение 30 секунд). После того как сервисы подходят, вещи, кажется, работают хорошо.

Кроме того, я нашел, что получаю эту ошибку при перезапуске сети:

sudo /etc/init.d/networking restart

[....] Restarting networking (via systemctl): networking.serviceJob for networking.service failed because the control process exited with error code. See "systemctl status networking.service" and "journalctl -xe" for details.
failed!

Таким образом, я думаю, что это имеет некоторое отношение к переименованию/установке интерфейсов. Я следовал инструкциям здесь для изменения личинки: Менять имя Сетевых интерфейсов Ubuntu 16.04 затем я создал/etc/udev/rules.d/70-persistent-net.rules:

# spectrum
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="f0:4d:a2:24:99:af", ATTR{dev_id}=="0x0", ATTR{type}=="1", NAME="eth0spectrum"

# name1.lan
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:1b:21:86:52:31", ATTR{dev_id}=="0x0", ATTR{type}=="1", NAME="eth1name1"

# name2.lan
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:1b:21:86:52:30", ATTR{dev_id}=="0x0", ATTR{type}=="1", NAME="eth2name2"

# available
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:1b:21:86:52:33", ATTR{dev_id}=="0x0", ATTR{type}=="1", NAME="eth3"

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:1b:21:86:52:32", ATTR{dev_id}=="0x0", ATTR{type}=="1", NAME="eth4"

Затем настроенный/etc/network/interfaces:
