Eu criei 2 servidores Ubuntu com adaptadores de ponte para rede interna e internet em configurações de rede.Depois que eu adicionei / etc / network / interfaces para usar a rede para endereço IP estático.
(changed in both servers 110/111)
# The host-only network interface
auto eth1
iface eth1 inet static
address 192.168.1.111
netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255
Mas não poderia funcionar, do que eu mudei manualmente na página de conexões de edição do Ubuntu como 192.168.1.110/255.255.255.0/192.168.1.1 que eu verifiquei ambos servidor com ifconfig.Its funcionou.
Eu pinguei o servidor e funcionou.
test1@test1-VirtualBox:~/.ssh$ ping 192.168.1.110
PING 192.168.1.110 (192.168.1.110) 56(84) bytes of data.

Eu tentei criar uma conexão ssh.
sudo apt-get install openssh-server
sudo apt-get install openssh-client
ssh-keygen
Eu tentei enviar id_rsa.pub para dodo machine.Mas eu tenho o seguinte error.So agora eu posso usar o ping, mas não posso usar scp ou ssh, como posso corrigir isso?
test1@test1-VirtualBox:~/.ssh$ scp -v id_rsa.pub [email protected]:/home
