A virtual machine
1. Load the virtual machine in NAT network card mode
two。 It is best to modify the hostnames of several used virtual machines, static IP / etc/network/interface, here is S101 S102 S103 three host ubantu, change / etc/hostname file
3. Install ssh
Create a public and private key on the first host S101
Ssh-keygen-t rsa-P''- f ~ / .ssh/id_rsa
> cd .ssh
> cp id_rsa.pub > authorized_keys create key Store
Transfer id_rsa.pub to another host, to the .ssh directory
Through the server nc-l 8888 > ~ / .ssh/authorized_keys
Client nc S102 8888
