How to ssh to linux

Getting Started With SSH in Linux

Thanks to the connected world we live in, you don’t need to have physical access to your server anymore. Your server can be anywhere in the world and you can connect to it from your local machine.

There are many protocols and tools which are developed for this purpose. Those include telnet and ssh. Telnet is not preferred due to security concerns. On the other hand, ssh is the popular means of securil connecting to remote systems.

In this article, I will cover some useful commands and tools a Linux user must know to use a remote system and its resources over ssh.

Note that most of the commands that you run on your personal local Linux system should be available on the remote system also (such as ls, cat, cd command etc). But running them depends on the permissions allotted to a remote user as with any Linux/UNIX system.

What is SSH?

The ssh or secure shell is a network protocol for operating networking services securely over a network. It uses encryption standards to securely connect and login to the remote system.

It stores a public key in the remote system and private key in the client system. Thes keys are produced as a pair mathematically. When both are applied to a bi-variable function, it will result in a value which will be used to check whether the pair is valid or invalid. This is the simplest explanation possible. To Learn more, please refer to this page.

Examples of using SSH

Let’s get started with setting up ssh and really cool use cases.

Generate ssh key

Websites such as GitHub and Heroku are asking for your ssh public key so that you can push/deploy code without entering a password and you don’t have such a key-pair? Don’t worry. You can generate such ssh key pair with this command:

It will prompt for a key-location (where the key will be saved) and passphrase (i.e. password). The passphrase is optional.

If the key-location is DIR_PATH/keypairforssh, there will be two files

1 is the private key file which you must not share with anyone
2 is the public key file which can be shared with remote systems (by means of other trusted communication such as mail, physical transfer, and other secured communication tools) and services such as Github, Heroku for the respective use cases. Be sure to check thoroughly about the service for which you are connecting.

Add private key to the key-agent

When the key pair is created, it justs exists as a set of two files. In order to connect to the remote system, it has to use the private key. So one should inform that this DIR_PATH/keypairforssh is the private key.

This is done by

Connect to remote host via SSH

If the private key and public key are in the right places, then you can connect to the system in this way.

Where username should be a valid user on the remote system and hostname is DNS-recognizable or an IP address so that ssh can contact the remote system and request for connection.

As explained before, the above command uses the private key on the local system and public key on the remote system and verifies these are valid pairs. It allows login if and only if key pair is valid and spawns a shell (type depends on the configuration for the user on the remote system) for your use. You can use the remote system as you are using the local system.

Suppose the private key is not added to the key agent, then you can do ssh login as below.

This checking of key pairs is usually done once. Ssh adds the remote host to the list of authorized hosts for future usage.

Copying files between client and remote systems

The scp command is a tool built on the top of ssh. It allows users to copy files and directories from remote to client and vice versa.

Since scp command uses ssh, it needs the same requirement as ssh. It means that the public key should be on the remote system and the private key should be on the local system.

Where DIR_PATH_1/DIR_PATH_2 are both paths that are either remote or local filesystem paths. For example, To transfer

/Documents/documentForLinux.txt to ‘linuxHandbook‘s /home/seeni/Documents directory

To copy the same file in reverse direction,

Mounting remote filesystem or directory

To mount remote system directories to the client, sshfs is the tool
developed for this specific purpose.

The above command is totally intuitive. Here, ‘name’ is the username accepted on remote system and server is the remote ‘hostname’.

In some systems, sshfs may not be available, install it if you need it.

Tip: The nohup command allows you to keep on running commands even after you disconnect your SSH connection.

Conclusion

Congratulations, you did make it to the end. I hope this article covered all the basic commands and tools related to ssh. These tools are just enough to get started with remote computing with ssh.

In a related article, you can learn about tmate. It’s a tool that allows you to share your terminal session over SSH.

How to SSH Linux, How to connect to SSH Terminal

How to SSH to a Linux server? Well in this tutorial we will show all the possible ways to connect to a server using SSH clients.

List of content you will read in this article:

As you might already know, the majority of servers on the internet are running the Linux operating system. While having an on-site server is the most secure way to manage it, in the majority of cases, such a system is either impossible or not optimal for the user. That is why most opt for either having their own servers installed within a datacenter or rent out a ready-made one in a colocation facility.

In such cases, in-person server management can prove to be difficult, making remote server access a necessity. To connect to a Linux server remotely and manage it over the internet you will have to use SSH.

What is SSH?

SSH (Secure Shell) is a network protocol used to send and receive data and other information over the internet without the fear of eavesdropping and getting important data stolen. Once you have developed a secure SSH connection, you are endowed with the permission to manipulate the server by merely typing the commands on your local computer.

When someone wants to manage the computer remotely in a secure way, the person uses SSH commands to get the work done. This protocol is especially loved by system and network administrators for the control and agility it provides to the users. Here are some of the things you can do with it:

SSH Work Methodology

SSH requires two basic components to complete the process of establishing a connection and allow you to remotely control the server. These components are:

The client is an application which you need to install on your computer to connect to the remote server or other computers within the local network. The remote host information is the key factor the client uses to establish the connection. When these credentials are deemed verified, the client becomes able to encrypt the connection.

The other component, on the server-side, is the SSH daemon that is on a continuous watch to listen to the specific TCP/IP port for any query or possible client connection requests. Once the client has initiated the connection, the SSH daemon will reply and respond as per the software protocol. If the credentials that the client has provided are correct, it will create a favorable environment for them to interact with each other.

Version 2 is the default SSH protocol version for SSH communication between a client and an SSH server.

Enabling an SSH Connection

As per the requirement of the connection, there are two parties involved in an SSH connection; one is the client and the other is the server. You have to make sure that the remote machine and local system both have SSH connections installed and enabled on them.

The most famous open-source tool for SSH is OpenSSH. This tool is comparatively easy-to-use and only requires terminal access to the server to which you are trying to connect.

OpenSSH

OpenSSH is one implementation of the SSH protocol on the server and client that is completely open-source.

Installation of Open SSH client

Most of the time, Linux-based distributions already have an SSH client installed on them, however, if you are using Ubuntu, be informed that the SSH server is not installed on it by default.

For Windows-based machines, install PuTTy or any other SSH client software to gain access to the server. Do also keep in mind that you will have to enable OpenSSH on your Windows device.

The process starts with the following steps:

Step 1: Load SSH terminal

Step 2: Press CTRL+ ALT + T at the same time

Step 3: Type in ssh and press Enter

If you have already installed the client on your system, the output will look something like this:

Install the OpenSSH client manually:

Type in the following command:

sudo apt-get install openssh-client

Then, type the superuser password and press Enter to complete the installation.

Install an OpenSSH Server

The installation of the OpenSSH server will require the following steps.

Step 1: Open terminal on the server machine

Step 2: Press CTRL + ALT + T

Step 3: Type ssh localhost and press Enter

If the system does not have an SSH server installation, you will see the following text:

If you see this message, you will have to manually install the SSH server.

Run this command to do so:

sudo apt-get install openssh-server ii.

Now, type in the superuser password. This will install the support file and you will be able to check the status by this command:

sudo service ssh status

What is KiTTY?

The fork form version 0.71 of PuTTY is known as KiTTY. This is undoubtedly the best telnet / SSH client in the world. KiTTY was originally designed for the Microsoft Windows platform and has all the features and add-ons from the original software.

Note that SSH and Telnet is not the same.

Pre-built binaries of KiTTY can be used and are available for macOS and Linux. Use any one of your favorite package managers to install the KiTTY package. It is available for the following:

Possibilities are endless and it is specifically designed for power keyboard users. The people who want to control all the work by using the keyboard love the keyboard shortcuts Kitty offers them. However, if you want to use a mouse, you can also do so to achieve your tasks.

Codes in KiTTY are fabricated to be very simple, hackable, and modular. The codes are specifically written in C (for performance-sensitive parts) and Python (for easy hackability of the UI). The dependence is not inclined on large and complex UI toolkit. The most famous and top-rated feature of KiTTY is that it can be easily extensible. You can add new features without any significant effort.

Tabs Top Level Organization

You can run multiple programs and organize them by manipulating various windows. The top-level organization of windows is Tab. There are several windows in each tab. You get the liberty to arrange these windows in various tabs.

Here you can see the keyboard controls for managing windows.

Configuring kitty for SSH

The high customizability allows you to use keyboard shortcuts to perform almost any operation. You can also create your very own keyboard shortcuts. If you want to configure KiTTY with SSH, you must do the following.

Step 1: Type kitty.conf

Step 2: Enter the following command:

Step 3: Begin the configuration by typing the following command:

Step 4: Open a new kitty window and type the following:

You will see a new window that will be running the cat program.

Step 5: To check the accessibility, type the following command:

Solar-PuTTy

If you want to connect to your routers, switches, and server over SSH you can find great benefits within this protocol. The UNIX shell environment can be perfectly used by a Windows user through Solar-PuTTy. This powerful software is open-source, and it is free for anyone to download and use.

Installation of Solar-PuTTy

Solar-PuTTy is available from SolarWind’s official site.

How to Use SSH to Connect to a Remote Server in Linux

Use code KB4KDO0L9 to receive a 10% recurring discount on any server.

Just as we use remote controls for our devices that are a few feet away, remote logins allow people to work from anywhere by accessing a remote server. Nowadays, we can hardly imagine a world where we can’t control computers from remote locations. The two most used protocols to establish a connection with a remote machine are Remote Desktop Protocol (RDP) for Windows-based machines, or Secure Shell (SHH) for Linux-based machines. To establish a remote connection, these two protocols use client and server applications. Once you establish a connection with a remote machine, you can do anything you would if you were sitting in front of the machine, for instance: transfer files, access and manage other computers, and so on.

Requirements for SSH

However, there are some necessary conditions to fulfill to use an ssh command: you need to have a network connection, and the remote computer needs to be turned on all of the time; you need to install and enable the client and server applications; you need the name or the IP address of the remote machine you are trying to connect to; you need to have the required permission to access the remote server, and the remote connection needs to be allowed by the firewall settings.

Terminology

Before we jump into the SSH program, it is essential to clear up the terminology used in the IT community related to this issue.

Remote: A remote computer is a computer that is in a remote location, and you’re not physically using it.

Local: A local machine is a computer you’re currently using and can be accessed without a network. The local port is the port number on the local computer. Unlike the local port, the remote port is the port number on the remote computer.

Some other terms you might want to look into before going into SSH are: ssh config file, ssh command line options, remote command, authentication agent connection forwarding, local forwarded ports, public key file format, transport layer, debug logs, securely publish, ssh client program, per user configuration file, remote computer, generic message exchange authentication, cipher specification, transport layer protocol, print debugging messages, and how to do ssh from windows to Linux.

What is SSH?

SSH, also known as Secure Socket Shell, is a protocol that gives users a secure way to access a computer. SSH is used by anyone who needs to remotely manage a computer in a secure manner, as well as system and network administrators. Secure Shell SSH provides public key authentication and password authentication, and encrypted data communications between the two computers connected over an open network. Secure shell protocol connections are encrypted using symmetric encryption, asymmetric encryption, and hashing.

Each SSH has a key pair. The ssh key pair includes a public and private key. Ssh keygen is a crucial part, since ssh keygen is a tool for creating new authentication key pairs. To provide a public key, each user account in your system must generate a public key if they don’t already have one. One of the ssh keys, the private key, is a secret, and it is stored on the computer you use to connect. The host key is used as one of the authentication methods. The ssh protocol provides strong encryption, authentication protocol methods like public key authentication, and a secure connection. The ssh protocol uses ssh utilities for managing applications and systems remotely, logging in to another computer, moving files from one computer to another, and executing commands. SSH tunneling or port forwarding creates an encrypted SSH key connection between a server and a client through which service ports can be relayed. Port forwarding can be used for going through firewalls. Port forwarding can also be used for adding encryption to the legacy application. Some people use port forwarding for opening backdoors into the internal network.

History of SSH

SSH’s first version emerged in 1995. It was designed by a researcher at the Helsinki University of Technology named Tatu Ylönen.

Over the years, some flaws were found in the initial version of SSH, called SSH-1, which is why this version is now considered to be not safe to use and deprecated. The current version of SSH, called SSH-2, uses a stronger integrity check with ssh authentication codes and a Diffie-Hellman key exchange to improve security.

SSH Linux Based Machines

One of the most attractive features of Linux is the ability to use a computer without entering commands into the keyboard and to do that on any computer in the world. Although establishing an SSH connection is a daily task for many Linux users, it can be a little intimidating for anyone who hasn’t tried it yet. Mac OS allows you to easily and quickly connect to a server with its built-in SSH client called Terminal. Read more if you want to find out How to SSH on a Mac. There are different types of ssh clients. With Putty, you can create a virtual private network. At ServerMania, we offer Linux Dedicated Servers.

How to Enable an SSH Connection

To enable an SSH connection, we first need to know how SSH works. To establish an SSH connection, you need a client machine and an agreeing server-side component. SSH enables a secure connection between these two. The application you install on the computer and connect to another computer is called an SSH client.

The client uses the remote host information to start the connection. It establishes the encrypted connection if the provided credentials or the remote hosts are verified. To enable a connection, you need to ensure that both the client computer and a server component are installed on the local machine and the remote machine. OpenSSH is an open-source SSH too, and installing it is relatively easy.

SSH Command Examples and Options

If you’re wondering how to SSH connect to remote computers, we’re going to look at some of the basic SSH commands:

pwd – show current directory;

How to Install an OpenSSH Client

Because many Linux ssh distributions already have an SSH client, you need to make sure that an SSH client isn’t already installed. You can easily establish remote connections with SSH. To check if an OpenSSH client is available on your system that is Linux-based, the SSH Linux command is CTRL+ALT+T on your keyboard or search for “terminal”. Then you type in ssh and press Enter in the terminal. In case the OpenSSH client is installed, you will get the following response:

$ ssh usage: ssh [-1246AaCfGgKkMNnqsTtVvXxYy] [-b bind_address][-c cipher_spec] [-D [bind_address:]port] [-E log_file] [-e escape_char] [-F configfile] [-I pkcs11] [-i identity_file] [-J [[email protected]]host[:port]] [-L address] [-l login_name] [-mmac_spec] [-O ctl_cmd] [-o option] [-p port] [-Q query_option] [-R address] [-S ctl_path][-W host:port] [-w local_tun[:remote_tun]] [[email protected]]hostname [command] [email protected]:

If you don’t receive this message, it means that you will need to install the openSSH client. To install OpenSSH client on your computer, run the following ssh command:

sudo apt-get install openssh-client

Then, when asked, type in your superuser password and hit Enter. Now, you are able to SSH into any machine if you have the needed privileges to gain ssh access to it. Verbose mode provides additional detail about what software and drivers the coputer is loading during startup.

How to Install an OpenSSH Server

A machine needs to have the server-side part of the SSH software in order to accept SSH connection. When started, the OPEN SSH server reads a configuration named /etc/ssh/sshd_config. The /etc/ssh/sshd_config file allows you to set options that modify the operation of the daemon.

You can try to connect to the local host, if you want to check if OpenSSH server is available on the remote host that needs to accept SSH connections, more specifically, on its Ubuntu system. You can do this by opening the terminal on the server machine and pressing CTRL+ALT+T on your keyboard or searching for “terminal”. Then, you type in ssh localhost and press enter. The response for the remote system without the SSH server will look like this:

$ ssh localhost ssh: connect to host localhost port 22: Connection refused [email protected]:

If you don’t have an OpenSSH server installed, you will need to install it by running the following command:

sudo apt-get install openssh-server ii.

Then, when asked, you will type in your superuser password and press Enter and Y to allow the installation to continue. You can check if the SSH server is running on the machine by typing in:

sudo service ssh status

If the SSH service is running properly, the response should look like this:

There is also another way to check if you installed the OpenSSH server properly, and that is by running the locahost ssh command in your terminal prompt again. The response should look like this:

$ ssh localhost The authenticity of host ‘localhost (127.0.0.1)’ can’t be established. ECDSA key fingerprint is SHA256:9jqmhko9Yo1EQAS1QeNy9xKceHFG5F8W6kp7EX9U3Rs. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added ‘localhost’ (ECDSA) to the list of known hosts. [email protected]:

Then, to continue, you just need to enter yes or y, and you’ve successfully set up your server to accept a SSH connection.

Connecting to an SSH Server

We will use the ssh command in order to connect to a remote machine using SSH.

To connect to a remote machine, the most basic form of this ssh command is:

The remote_host is an example of the domain name or the IP address that you want to connect to. You can use this command if the username on your local system is the same as the username on the remote user. You can use the following basic syntax for the ssh command if the remote machine has a different username:

You might be asked to provide a password to verify your identity once you’re connected to the server. To return to your local shell session and exit the ssh session, all you need to do is type:

Connecting to a Remote Server Over SSH on Linux

A secure shell (SSH) is used for secure communication between devices. When most people refer to SSH, it is within the context of a connecting from a local computer to a remote server, commonly for administration tasks related to website hosting.

This article covers the basics of connecting to a remote server (such as a Linode) over SSH on a Linux system.

Before You Begin

Ensure you have a Linux server with an SSH server (like OpenSSH) installed. Most Linux distributions have an SSH server preinstalled. If you wish to deploy a new server, follow the Creating a Compute Instance guide to create a Linode.

Your local computer needs an SSH client that can be used through a terminal application. Most modern Linux distributions have SSH installed and ready to use.

Open the Terminal

On your local computer, open the terminal application you wish to use. The terminal allows you to access your operating system’s shell environment and run programs through the command line.

If you’re using Linux through the command line, you are already in the terminal and can skip this section. If you are using Linux through a desktop environment (a graphical interface), you’ll need to locate and open the terminal application that comes with your Linux distribution and desktop environment. In most cases, pressing Ctrl + Alt + T on your keyboard opens the default terminal.

If this key combination does not work for you, other instructions for opening a terminal vary depending on the Linux distribution and desktop environment you are running. In many cases, you’ll want to open the application search tool and search for “terminal”.

Connecting to the Remote Server Over SSH

Within the terminal, enter the following command, replacing [username] with the username of the remote user and [ip-address] with the IP address or domain name of the remote server.

The SSH client attempts to connect to the remote server over port 22 (the default SSH port).

When you connect with a server for the first time, the SSH client prompts you to check and verify the host key’s fingerprint. This is normal, and results in output similar to:

You can verify the fingerprint by following the instructions on the Verifying the Authenticity of a Remote Server guide.

If you recently rebuilt your server, you might receive an error message when you try to connect. This happens when remote host key changes. To fix this, revoke the key for that IP address.

Ending the SSH Session

At this point, the shell prompt returns to the one for the local workstation and the terminal application can be closed if it’s no longer needed.

Sending Commands Over SSH

Instead of using SSH to open your remote server’s console, you can run commands on your server without leaving your local shell environment. This can enable you to quickly run commands both locally and remotely in the same terminal window.

Sending a Single Command

To run a single command on your remote server, use the following command. Replace [username] with the username of the remote user, [ip-address] with the IP address or domain name of the remote server, and [command] with the command you wish to run.

Sending Multiple Commands

To run multiple commands on your remote server (one after the other), use the following command. Replace [command-1], [command-2], and [command-3] with the commands you wish to run.

Using sudo

Going Further

Troubleshooting SSH Connection Issues

If SSH isn’t connecting you to your Linode, you may need to investigate the state of your server. See the guide Troubleshooting SSH for assistance.

Increasing Security

Now that you can connect from your Linux machine to the Linode over SSH, save not only time but also make the connection even more secure by using SSH public key authentication. For more information, see SSH add keys.

See the “Harden SSH Access” section of Setting Up and Securing a Compute Instance guide to review how to secure SSH on the server’s side, and the Advanced SSH Server Security for more information on making it even more secure.

How to Set Up SSH on Linux: A Full Guide for Beginners

If you are a Linux user then you should know that one of the most important ways of using Linux is via SSH. You can do everything from installing software to configuring Linux as a web server with the help of remote access command line tool. SSH can save time, make you more productive, and help you unlock the power of your Linux distro.

But do you know how to Set Up SSH on Linux on both the client and server sides? If you don’t then here in this article of MAZHD, we will show you how to install and configure SSH software at both ends and remotely control your Linux computer.

Table of Contents

What Is SSH?

Simply SSH stands for Secure Shell and allows you to remotely control a Linux computer or server from another device. SSH (Secure Shell) works across local area networks and the internet. By saying that we meaning that it can be used to manage a Linux-powered media server in your house, or a Linux web server on a different continent.

SSH lets you use the terminal but doesn’t give you access to the remote computer’s desktop environment. When it’s connected to the remote computer you can use it as if it was right in front of you. Just be sure to have root access.

Remember that to use SSH, you’ll need to ensure that the remote computer (server) has SSH set up. Additionally, your local device (the client) will need an SSH app installing.

Client-Side Installation

It is easy and simple to install and set up SSH on a client. And may be there is no need to use any additional software.

Follow the steps below:

SSH not installed on your Linux system? Add by updating packages and upgrading, then installing:

If you have recently switched to a Linux desktop but you used SSH on Windows then you might miss the PuTTY desktop SSH app with its easy mouse interface. But don’t worry, it can be installed on a Linux desktop:

When you are done installing SSH client software, you’re ready to set up a connection to your remote computer or server.

Remember that for all desktop and mobile clients, all you need is an IP address or host name, and appropriate login details. While the look of the apps may differ, and the port name may need entering manually, SSH clients are mostly indistinguishable.

Server-Side Installation and Configuration

Install the server-side software to host your SSH connection before establishing a connection. This requires someone to be present to install or enable SSH. You might already be present to do this—otherwise, a colleague or support engineer at the server end will set up SSH.

Remember that if you’re using a web hosting package, SSH should be enabled by default. Speak to your web host to set up SSH if not.

If SSH is not enabled on the remote computer or server, install it with

Check this worked with

The command should illicit a response of “active.”

In some cases the Ubuntu firewall ufw may block SSH. To ensure this doesn’t happen, use

In some cases you’ll need to also enable SSH on the remote device. This is a security precaution that can be tweaked using

Determine IP Address

You have to find IP address of the machine in order to connect to the remote device over SSH. mostly it’s done via two easy ways.

To display the IP address of the remote system, logon and run

This will return the device’s IP address, so take a note of it. On older Linux versions ifconfig may provide better results.

You can also check your router to see connected devices. The Linux PC or server will be listed, typically by operating system or device name. This should make it simple to identify.

To display the public IP address, login to the server and open whatsmyip.org.

It’s better to use the IP address which is suitable for the connection. Use the local IP address if the device is on the same network as the client. And use the public IP address for connections across the internet. If the computer is located on a different network, make sure that port 22 is forwarded to the computer.

Connecting to Linux via SSH

In addition to correct IP address, you should also have a username and password to gain access to the remote machine.

For command line SSH tools, use

Remember to replace username with the actual username and REMOTE.IP.ADDRESS.HERE with the remote device’s IP address. Then hit Enter, and you’ll be prompted for the password.

With a correct password, you’ll get a functioning terminal prompt—you’re now logged into the remote computer.

Using a desktop SSH client like PuTTY?

After doing the steps above, input the Host Name or IP address, select the SSH connection type, then Open. When prompted for your username and password, enter them in the command line window to complete the connection and gain remote access.

Can’t Connect? Troubleshoot Your SSH Set Up

If you are done the process above and you still can’t connect or you are having SSH connection issues, these are the possible causes:

Double-check each point and you should be able to connect. If not, the problem might be more complex.

Using Linux Remotely With SSH

Moreover, SSH is a useful tool for managing one or more Linux computers.

With the help of SSH you can work on any machine from just one system. You can input almost any Linux terminal command over SSH.

Key examples include:

Setup SSH and Make Linux More Powerful

With the help of SSH, Linux becomes considerably more flexible and powerful. You can literally remotely access a computer using a smartphone thanks to SSH.

Moreover, if SSH is set up correctly, with client and server-side software enabled and configured, remote command line access is possible.
