If you restart service then it will work

$ service sshd restart

then check

$ ssh localhost

It will work

Answer 2

1. Before installing/reinstalling anything check the status of sshd . . .

sudo systemctl status sshd

2. You should see something like . . .

● sshd.service - OpenSSH server daemon
   Loaded: loaded (/usr/lib/systemd/system/sshd.service; disabled; vendor prese>
   Active: inactive (dead)
     Docs: man:sshd(8)
           man:sshd_config(5)

3. Just enable and start sshd

sudo systemctl enable sshd
sudo systemctl start sshd

Answer 3

I used:

sudo service ssh start

Then:

ssh localhost

Answer 4

If you still face problems, try the following:

sudo ufw enable    
sudo apt-get install openssh-server

This might work too.

Answer 5

If install Hadoop on Mac OSX, make sure turn on Remote Login under System Preferences then File Sharing. This worked on my machine.

Answer 6

ssh localhost -p 8088
