How to install ssh in linux?

@monroe.bahringer 1. Check if your Linux version already has SSH installed. Open a terminal window and enter the following command:

1

type -a ssh

If the output is returned similar to this, then SSH is already installed:

1

ssh is /usr/bin/ssh

Install SSH using the package manager If your Linux version doesn’t include SSH by default, you’ll need to install it manually using the appropriate package manager. For Debian/Ubuntu, this is apt-get:

1

sudo apt-get install openssh-server

For Redhat/CentOS, it’s yum:

1

sudo yum install openssh-server

Confirm that SSH is running. Once installation is complete, you’ll want to confirm that SSH is running. You can do this by entering the following command:

1

sudo systemctl status ssh

This will check the status of the service. If it’s running correctly, you should see an output similar to this:

Active: active (running) since Mon 2017-07-17 12:42:32 UTC; 2min 12s ago

Connect to your server using SSH. Once you’ve confirmed that SSH is up and running, you can connect to your server using the following command:

1

ssh user@IP_Address

Replace user with your username and IP_Address with your server’s IP address. You’ll be prompted to enter your password and you’ll be logged in. Congratulations, you’ve successfully installed and connected to your server using SSH!
