Enable the SSH service in ubuntu, and enable ssh in ubuntu

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 a default installation, if not, sudo apt-get install openssh-client ), to enable the SSH service on the local machine, 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 as follows:
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:
The ssh username@192.168.1.112 username is the user on the 192.168.1.112 machine and requires a password.
Disconnect: exit
