Ubuntu 12.04 SSH 安装

By default Ubuntu Desktop OS comes with ssh clientpackage. It does not include ssh server package which is needed to access this machine.

To install SSH on the newly installed Ubuntu 12.04 run following commands

sudo apt-get update
sudo apt-get install ssh
sudo /etc/init.d/ssh restart

That’s it. To confirm the working ssh. Run the following commands from another machine

ssh username@IP_of_the_ubuntu_machine

If you get following error then
1. ssh is not running on the remote server
2. ssh is configured to run on different port

ssh: connect to host 192.168.1.10 port 22: Connection refused

Also remember to open ssh port between remote and host machine for communication.
