When you make changes to the SSH configuration, you’ll need to restart the service in Linux.ĭepending on the Linux distro, run one of the following commands on the machine where you modified the settings: sudo ssh service restartįinally, enter the password to complete the process. In the command line on a remote host, type in: sudo vim /etc/ssh/sshd_configĮnter the sudo password, and the shell opens the file in the editor you used. You’ll need superuser permissions to make changes. Use the editor of your choice to edit the file. A server can become inaccessible due to bad configuration. Make sure to edit only the options you are familiar with. Edit the settings in the sshd_config file to customize SSH server options. You can control how remote users can access a server via the SSH. Make sure to use the uppercase -Pflag if you need to specify the port. The output shows a summary of the operation. The basic syntax is: scp fileName :/home/username/destinationįor example, to copy a file sample3 to your Desktop on a remote server with a username test, type in: scp sample3 :/home/test/Desktop You can securely copy files over the SSH protocol using the SCP tool.

To use default settings, hit Enter on the prompts for file location and passphrase. On the host machine’s terminal, use this command to create a key pair: ssh-keygen -t rsa When you create an SSH key pair, there is no longer a need to enter a password to access a server. SSH key pairs are used to authenticate clients to servers automatically. The public key can be shared, while the private key needs to stay secure. The pair consists of a public and private key.
