Enable SSH Ubuntu 16.04

This quick tip shows how to enable Secure Shell (SSH) service in Ubuntu 20.04 LTS, both desktop and server, to allow secure remote login and other network communications.

Ubuntu includes OpenSSH, a suite of secure networking utilities based on the Secure Shell protocol, in its main repositories. While OpenSSH client is installed out-of-the-box, you can do following steps to install and setup OpenSSH server in Ubuntu 20.04.

1. First open terminal and run command to install the packages:

sudo apt install ssh

Type user password (no asterisk feedback) for sudo prompt and hit Enter.

2. Once installed, SSH services start in background silently. You can check its status by running command:

systemctl status ssh.service

You may replace status in the code with stop, reload, restart to stop, reload, or restart the service.

3. The SSH service should be working good now for basic use! If you want to change the listening port, root login permission, or other authentications, run command to edit the configuration file:

sudo nano /etc/ssh/sshd_config

replace nano with gedit if you’re on Ubuntu Desktop.

Save changes by pressing Ctrl+X, then Y, and finally hit Enter. And remember to restart the SSH service via sudo systemctl restart ssh.service command.

Secure Shell (SSH) is a protocol for securely accessing remote machine, it allows you to run command line and graphical programs, transfer files, and even create secure virtual private networks over the Internet.

Ubuntu does not provide the ssh service out-of-the-box. But you can easily enable it by installing the OpenSSH server package.

To enable SSH:

Search for and install the openssh-server package from Ubuntu Software Center. Or run command below in console if you’re on Ubuntu Server without GUI:

sudo apt-get install openssh-server

Once installed, the SSH service should be started automatically. If necessary, you can start (or stop, restart) the service manually via command:

sudo service ssh start

To edit settings:

To change the port, root login permission, you may edit the /etc/ssh/sshd_config file via:

sudo nano /etc/ssh/sshd_config

After you changed the configurations, press Ctrl+X followed by typing y and hitting enter to save the file.

Finally restart the SSH service to apply the changes:

sudo service ssh restart

Usage and Tips:

1. Normally, we can access remote machine through SSH via command:

ssh [email protected]

For the port that is not the default 22:

ssh [email protected] -p NUMBER

2. For desktop Ubuntu, root user need to be enabled first so that remote machines can SSH to it via root:

Run command below to set a password for root:

sudo passwd root

Then execute command to unlock the root account:

sudo passwd -u root

Edit the config file /etc/ssh/sshd_config, change the line

PermitRootLogin without-password

into:

PermitRootLogin yes

When done, restart the SSH service.

This simple tutorial is going to show you how to enable Secure Shell (SSH) service in Ubuntu 14.04 Trusty Tahr.

Secure Shell (SSH) is a cryptographic network protocol for secure data communication, remote command-line login, remote command execution, and other secure network services between two networked computers.

SSH is not enabled by default in Ubuntu, but you can easily enable this service via OpenSSH, a free version of the SSH connectivity tools developed by the OpenBSD Project.

To do so, run the command below in terminal:

sudo apt-get install openssh-server

Or install the openssh-server package via Ubuntu Software Center if you’re on Desktop edition:

install ssh server Ubuntu 14.04

Once installed, you can change the port, disable root login and do other changes by editing the config file:

sudo gedit /etc/ssh/sshd_config

Finally restart the ssh server to take place:

sudo /etc/init.d/ssh restart

That’s it. Enjoy!

enable ssh ubuntu 13.10

This simple tutorial shows you how to enable ssh in Ubuntu 13.10 Saucy Salamander. As you may know, SSH (Secure Shell) is a secure communication protocol that lets you remotely access networked computers. It is known as a replacement for Telnet which is very unsecure. While Telnet sends traffic in plain text, SSH on the other hand uses a secure protocol to communicate.

Tutorial Objectives:

  • Enable SSH in Ubuntu 13.10
  • Enjoy!

To get started, install SSH Server openssh-server from Ubuntu Software Center. Or run command below if you’re on Ubuntu Server without GUI:

sudo apt-get install openssh-server

That’s it. Use your client to connect to this machine via the default port 22.

You can change the port as well as disable root login and other settings by editing the config file /etc/ssh/sshd_config via root privilege:

sudo gedit /etc/ssh/sshd_config

Enjoy!
