Set up an ssh connection In Ubuntu (connection method: Bridging network adapter, Network Address Translation (NAT), and using tussh

Operating System: Ubuntu Server 16.04.2

SSH software: Putty (remote connection tool, depending on the local operating system select the corresponding version of putty)

 

-------------------------------- Network connection method: Bridging network adapter -----------------------------------

Step 1:

1) install openssh-server by running the following command:

Sudo apt install openssh-server

Because I have installed openssh-server on my local machine, it is inconsistent with the first installation (please ignore it !)

Tip: If [server] does not install openssh-server, we cannot remotely log on to [server];

Advantages: open-source, free, encrypted throughout the transmission process (Secure remote connection)

 

Run the following command to uninstall openssh-server:

Sudo apt remove -- purge openssh-server

Ubuntu system how to uninstall the deletion software: https://jingyan.baidu.com/article/59a015e39abf3df79588655b.html

The simplest method is that when we know the software name, we can simply enter the command in the terminal command window:

Sudo apt-get remove -- purge google-chrome-unstable

-- Purge indicates that the software modification and related files are permanently deleted.

2) view the IP address. The command is as follows:

Ifconfig or ip

 

Step 2:

1) install putty (my system is 64-bit, so I installed a 64-bit putty)

　　

2) Open putty. The connection requires two parameters: IP address and Port.

IP Address: 192.168.1.105 (ifconfig view)

Port: 22 (default ssh port)

If it is an ECS, the port is what they give. If it is not an ECS instance, the port is 22 (default ssh port );

 

-------------------------------- Network connection method: Network Address Translation (NAT )-----------------------------------

Network Connection Mode: Network Address Translation (NAT), that is, the so-called class A address (10. The IP address with the header)

Note that the remote machine cannot directly access the Class A address, and port forwarding settings are required (VMWareThere is no problem with the virtual machine)

ForVM VirtualBoxVirtual Machine Settings.

Host IP Address: IP address of the current operating system. Default Value: localhost (optional)

Subsystem IP Address: Virtual Machine

Forward data from Port 2222 of the external operating system (you can modify the port through sshd_config) to port 22 of the subsystem.

 

Next, it will be the same as the above operation. I will not talk about it here ~

 

------------------------ Problem ------------------------

VirtualBox error )/~~ Failed to solve the problem. I have no choice but to choose the vmwarevm. If you have any solutions, please help me solve it !!!
