There are many articles on enabling the SSH service in Ubuntu on the Internet, but most of the methods described are not ideal after testing, and remote login to Ubuntu is not possible, the reason is that the ssh-server service is not enabled. The final success method is as follows:

Sudo apt-get install openssh-server

Openssh-client is installed by default in Ubuntu, so it is not installed here. if your system is not installed, use apt-get to install it.

 

Then confirm whether the sshserver is started:

Ps-e | grep ssh

If only ssh-agent is available, the ssh-server has not been started./etc/init. d/ssh start is required. if you see sshd, the ssh-server has been started.

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 restart

Ssh connection: ssh linuxidc@192.168.1.1

 

1. first install the ssh server on the server.

$ Sudo aptitude install openssh-server

2. start ssh-server.

$/Etc/init. d/ssh restart

3. confirm that the ssh-server is working properly.

$ Netstat-tlp

Tcp6 0 0 *: ssh *: * LISTEN-

The above output indicates that the ssh-server is already running.

4. log on to the server through ssh on the client. Assume that the IP address of the server is 192.168.0.103, and the logon username is hyx.

$ Ssh-l hyx 192.168.0.103

Next, you will be prompted to enter the password, and then you will be able to successfully log on to the server.
