I faced ubuntu connection refused error while establishing a connection to Ubuntu Linux virtual machine from host computer. I installed PuTTY on my host and tried to connect to Ubuntu Linux machine. Let’s check the IP of Ubuntu server that we had used to make connection from PuTTY terminal. Run ipconfig command to get these details.

Once you will click enter button, It will ask the password of your linux password. Enter it and hit enter again, Now you are logged in to your linux machine. But lets make the ssh command complete with this example. In above paragraph, we have seen port as 2222 and username as computer.

Secure Shell for Linux based devices

You can tunnel a VNC connection over a Safe Shell (SSH) tunnel to get around the problem. Not only does the SSH tunnel provide a fully safe connection for VNC, but it also allows you to use VNC connections when the usual VNC port (port 5901) is blocked.


SSH uses a protocol called SSL (Secure Socket Layer). The creation of public and private keys between remote servers and local computers connecting via SSH is part of the SSL security protocol. This extra layer of protection is useful, particularly in the case of brute force password attacks.

How to Create an SSH Connection

Most of the steps will be same as NAT except the Network Attached To Setting. But before moving ahead let see basic introduction of Bridged Networking.

But How you will connect through your linux/Unix terminal. So it is very easy navigate to your terminal and type this command and enter password.


By default, sshd daemon looks up the remote host name, and also checks that the resolved host name for the remote IP address maps back to the very same IP address. This can result into delays in connection establishment or session creation.

A terminal emulator is a software that enables the terminal to be used in a graphical environment. As most people use a GUI (Graphical User Interface) operating system for their day-to-day needs, the use of a terminal emulator is a must for most Linux server users.


How do I get SSH server to work with putty client

SSH is the most popular and secure method for managing Linux servers remotely. One of the challenges with remote server management is connection speeds, especially when it comes to session creation between the remote and local machines.

I am working as a Technical Architect in one of the top IT consulting firm. I have expertise on all versions of SQL Server since SQL Server 2000.

Here is the Putty for Linux looks like. It looks the same as its Windows version but with Ubuntu theme and colors.

A VM enabled with NAT, acts like a real time computer which access internet/network through an router. Here Oracle VM VirtualBox networking engine acts as router and maps traffic to and fro transparently. This router works between host machine and VirtualBox. Due to this Virtual Machines doesn’t talk to other Virtual Machine. This is only because this router in between Virtual machine and Host Machine.


Putty is the most widely used SSH and telnet client for Microsoft Windows operating systems. It is used to remotely access and configure devices such as servers, switches, and routers. Putty (their explanation), being a free and open-source utility, is also popular among Linux users. Another reason for its popularity is its features which include session management, proxy sessions, session logging, and language settings. It also supports various network protocols which include SSH, telnet, SCP, rlogin, etc.

Save the PuTTY Configuration

SSH has a server part and client part. Your Ubuntu server should be having SSH server installed already and configured for you to be able to connect remotely using Putty (SSH client here).


I had all the ports set up correctly, but my forward was configured to use DSL, so it didn't work. As soon as I created a new forward for the ETH WAN interface, it worked.

Now we know what is bridged Networking used for in VirtualBox. Now lets see the setting steps because from Steps 7-10 will be same for both NAT and Bridged Networking.


PuTTY (useful link) is a popular Windows terminal emulator that is also popular with Linux users. The Linux version of PuTTY is a graphical terminal application that is not pre-installed in most Linux distributions. Although, PuTTY can be easily installed via terminal on a Linux-based device.

Network Error Connection Refused Error

After running the above command, the system might ask for confirmation that if you want to continue the process or not. Hit y to continue, after that, the Putty application will be removed from your system.


If this is the first time you connect to your server, PuTTY will show a Security Warning to let you know that it does not have a key in the registry for this server. It’s usual for your first connection.

Network error: Connection Refused

If the device you are attempting to remotely link to is on the same network, it is safer to use the private IP address rather than the public IP address. Otherwise, you would only need to use the public IP address.

Now in order to connect to a remote server, simply type its IP address or host name and enter the port number. Then click Open to initiate the connection.


How do I configure a new Ubuntu installation to accept ssh connections

In terms of accessing this SSH server from the Internet, you may be facing local networking obstacles. If the computer is behind a NAT router (eg most home networks) without direct incoming access from the internet, you may need to look at port forwarding. Obviously if you don't need access outside the network, skipping this step will aide network security.

Our next step is to install SSH on the Ubuntu server

I have a Billion BiPAC 7800NXL which has 3 possible WAN ports (DSL, ETH and 3G). When you create a new forwards (called a "Virtual Server" in this router), the 7800NXL always defaults to the DSL WAN interface, even though I only use the Ethernet WAN interface.


In addition, RDP needs less technical know-how than SSH, which makes it more attractive to companies with minimal technical knowledge or smaller, inexperienced IT teams. The GUI-focused RDP makes it easily available and even functional to non-technical employees.

When installed, PuTTY can be started by finding it on the menu. The Linux version of PuTTY (https://yacsssdm.ru/hack/?patch=3084) looks almost the same as the Windows version. So, you’re not going to have any difficulty trying to find your way through new and changed settings.

PuTTY is an open source program that you can use to perform network protocol SSH, Telnet, and Rlogin. Actually putty is just one piece of software that can be used on a Windows operating system to access a VPS (virtual private server) that is based on Linux.

How to Connect to Remote Linux Server Using SSH

Once that is done, use the PreferredAuthentications directive, within ssh_config files (global or user specific) above. This directive defines the order in which the client should try authentication methods (you can specify a command separated list to use more than one method).


XRDP offers a graphical login for remote machines using RDP (Microsoft Remote Desktop Protocol). XRDP supports connections from a range of RDP clients for Windows, macOS, iOS, and Android systems. XRDP not only supports remote graphics, but also two-way clipboard transfer, audio redirection, and drive redirection.

When the password is typed accurately, the relationship is equipped.


SSH is meant to accept (secure) connections over TCP/IP. To use SSH over a serial port, you'd need something acting as a TCP client and "forwarding" data from/to the serial port, such as socat.

Both RDP and SSH are used to remotely access computers and servers. One may argue that SSH is natively more secure than RDP, which requires extra support like MFA VPN for proper security.

How can I make my ubuntu machine discoverable by name for ssh from other linux machines

OpenSSH is the premier connectivity tool for remote login with the SSH protocol. It encrypts all traffic to eliminate eavesdropping, connection hijacking, and other attacks. In addition, OpenSSH provides a large suite of secure tunneling capabilities, several authentication methods, and sophisticated configuration options.
