In the previous office was 192.168.1.x
Now it's 192.168.2.x to the rental house.
So I'm going to change the IP of the current virtual machine to the same network segment as the rental house. Network Mapper can also be accessed

Su
Then prompt for a password
Despite the failure, I've been able to follow the codes in my memory for other operations.

sudo vi/etc/network/interfaces
Eth0 inet Static
Address 192.168.1.100
Netmask 255.255.255.0
Gateway 192.168.1.1
Actually, I don't know what the format is, but I can just follow the previous format.

sudo vi/etc/resolv.conf
I'm not sure about that, but I did.
NameServer 192.168.1.1

And then it's sudo reboot.

Just fine.
