Install and set up the SSH service in Ubuntu 12.04

1. Install
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.
Install ssh-server
Sudo apt-get install openssh-server
Install ssh-client
Sudo apt-get install openssh-client

2. Check whether sshserver is installed.
Ps-e | grep sshd
450? 00:00:00 sshd

If you see sshd, it indicates that the ssh-server has been started.
If only ssh-agent is available, it indicates that the ssh-server has not been started. You need to run the following command to start the ssh service:
/Etc/init. d/ssh start;
Note: Only sshd is displayed in the ubuntu-12.04-server-i386.iso installation:

3. Extended Configuration
The default SSH service port is 22. You can define it as another port, such as 222. The configuration file to be modified is:
/Etc/ssh/sshd_config
Modify the Port parameter to 222.
Then restart the SSH service:
Sudo/etc/init. d/ssh restart
