Linux Learning Note II: Ubuntu installation SSH (Secure Shell) service

Ubuntu does not have the SSH (Secure Shell) service installed by default, and if you want to link to Ubuntu via SSH, we need to install ssh-server manually.

SSH sub-client ssh-client, server Ssh-server.

1. Determine if the server is installing SSH service, you can use the following command
SSH localhost
Ssh:connect to host localhost port 22:connection refused//This indicates that the SSH service has not been installed

2. Installation commands
sudo apt-get install Openssh-server

3. Uninstall command
sudo apt-get remove Openssh-server

4. Check if the Ssh-server is installed properly
Ps-e | grep ssh
6566? 00:00:00 sshd

5. If not, you can start this way:
Sudo/etc/init.d/ssh Start or service ssh start
