There are many articles on enabling the SSH service under Ubuntu 9.0.4 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:

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

Sudo/etc/init. d/ssh resart
