Solution:
One possible reason is that because the
ssh server daemon
, or
sshd
, is not loaded and running on localhost, so any attempt to ssh connect to localhost would fail. I check to see whether ssh and sshd are running by typing the following command:
$ ps aux | grep ssh
# Result: bunch of lines, but none of them is about "sshd", only one line is about "ssh"
?
Result is, I only see ssh running, but not sshd. So I know ssh server daemon is probably not started yet.
First, I verify that I have installed the package “openssh-server” on my fedora box.
Then I check the status of sshd service:

You may not have OpenSSH completely installed. Type this in terminal:
sudo apt-get install openssh-client
sudo apt-get install openssh-server
?
Another problem that you could have is that your firewall could be blocking the ssh connection. I use Firewall Configuration to manage my ports and firewall.

to restart it type
sudo /etc/init.d/ssh restart

to stop it type
sudo /etc/init.d/ssh stop
?
to start it type
sudo /etc/init.d/ssh start
