У меня виртуальная машина Ubuntu VirtualBox работает на MacOS в качестве хоста.
Я настроил как сеть только для хоста под названием vboxnet0, она настроена вручную:
ip 192.168.0.15
netmask 255.255.255.0
not using dhcp
Виртуальная машина имеет только 2 сетевых интерфейса NAT Host.
В файле /etc /network /interfaces у меня есть следующие строки
# Host-only interface
auto eth1
iface eth1 inet static
address 192.168.0.15
netmask 255.255.255.0
network 192.168.0.0
broadcast 192.168.0.255
# NAT interface
auto eth2
iface eth2 inet dhcp
После этих настроек я могу пинговать виртуальную машину (192.168.0.15), но не могу подключиться к ней по ssh с хоста. Я просто получаю connection refused. ошибка.
Что случилось? Я отключил брандмауэр на виртуальной машине (просто чтобы убедиться, что это не из-за этого). Как заставить SSH работать между хостом и виртуальной машиной?
Обновление 1: бегущий route -n дает следующий вывод.
user@ubuntuvm-1:~$ route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
0.0.0.0 10.0.2.2 0.0.0.0 UG 0 0 0 eth0
10.0.2.0 0.0.0.0 255.255.255.0 U 1 0 0 eth0
192.168.0.0 0.0.0.0 255.255.255.0 U 1 0 0 eth1
Я подтверждаю, что брандмауэр не работает на виртуальной машине.
Еще одна вещь, которую я заметил, это то, что иногда (когда я отключаюсь от сети) даже пинг не работает.
Обновление 2: я изменил IP-адрес сетевого интерфейса
auto eth1 iface eth1 inet статический адрес 192.168.56.15 маска сети 255.255.255.0 сеть 192.168.56.0 широковещательная передача 192.168.56.255
Я изменил это настройки VirtualBox, а также.
вывод из Mac (хост), когда я делаю ssh -vvv является
