Remotely connect to Ubuntu via Xshell

Ubuntu Open sshd Service
SSH sub-client openssh-client and Openssh-server
If you just want to log on to another machine SSH only need to install Openssh-client (Ubuntu has default installation, if not then sudo apt-get install openssh-client), If you want to make the native SSH service open, you need to install Openssh-server
sudo apt-get install Openssh-server
Then confirm that the Sshserver is started:
Ps-e |grep SSH
If you see sshd that means Ssh-server has been activated.
If not, you can start this way: Sudo/etc/init.d/ssh start
Ssh-server configuration file is located in/Etc/ssh/sshd_config, where you can define the SSH service port, the default port is 22, you can define yourself as a different port number, 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 in to SSH:
SSH [email protected] tuns for users on the 192.168.0.100 machine, you need to enter a password.
Disconnect: Exit
