To configure SSH (or Secure Shell) we must understand that has become the standard for remote access, replacing the telnet protocol. SSH has made protocols like telnet redundant, mostly due to the fact that the connection is encrypted and passwords are not sent in plain text for everyone to see.<\/p>\n\n\n\n

Firts thing first we install the OpenSSH server with the command:<\/p>\n\n\n\n

sudo yum install openssh-server<\/strong><\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Configure SSH<\/h2>\n\n\n\n

We edit the \/ etc \/ ssh \/ sshd_config file<\/p>\n\n\n\n

First we make a backup of the original file.<\/p>\n\n\n\n

sudo cp \/ etc \/ ssh \/ sshd_config \/etc\/ssh\/sshd_config.old<\/em><\/strong><\/p>\n\n\n\n

We restrict the root user from being able to connect remotely.<\/p>\n\n\n\n

PermitRootLogin no<\/em><\/strong><\/p>\n\n\n\n

We change the default port from 22 to 2244.<\/p>\n\n\n\n

We restart the OpenSSH server.<\/p>\n\n\n\n

sudo systemctl reload sshd<\/em><\/strong><\/p>\n\n\n\n

For the OpenSSH server to start automatically when the CentOS 7 Operating System is turned on.<\/p>\n\n\n\n

sudo chkconfig sshd on<\/em><\/strong><\/p>\n\n\n\n

Create user for SSH to connect remotely we are going to create a new user.<\/p>\n\n\n\n

sudo adduser userpublico <\/em><\/strong><\/p>\n\n\n\n

sudo passwd userpublico<\/em><\/strong><\/p>\n\n\n\n

To configure the Firewall we open the port that we change.<\/p>\n\n\n\n

sudo firewall-cmd –permanent –add-port = 2244 \/ tcp<\/strong><\/p>\n\n\n\n

And we restart the Firewall.<\/p>\n\n\n\n

sudo firewall-cmd –reload<\/strong><\/p>\n\n\n\n

Test SSH connection from another machine we execute this command to log in remotely with the new user, where 192.168.1.20 is the IP of the OpenSSH server.<\/p>\n\n\n\n

ssh -p 2244 userpublico@192.168.1.20<\/strong><\/p>\n\n\n\n

And ready our SSH will already be configured in our CentOS system.<\/p>\n","protected":false},"excerpt":{"rendered":"
