SSH is divided into client openssh-client and openssh-Server
If you only want to log on to another machine for SSH, you only need to install OpenSSH-client (Ubuntu has default installation, if not, sudo
Apt-Get install OpenSSH-client). To enable the SSH service on the local machine, you need to install OpenSSH-server.
Sudo apt-Get install OpenSSH-Server
Then confirm whether the sshserver is started:
PS-E | grep SSH
If you see sshd, it indicates that the ssh-server has been started.
If not, start sudo/etc/init. d/ssh start or service SSH start.
The SSH-server configuration file is located in/etc/ssh/sshd_config. Here, you can define the SSH service port. The default port is 22. You can define other port numbers, such as 222.
Then restart the SSH service:
Sudo
/Etc/init. d/ssh stop
Sudo/etc/init. d/ssh start
Then use the following method to log on to SSH:
