Just a bit of information.....

If you see "No route to host" on an ssh connection it would indicate the port is closed.
When you see "connection refused" it means there is no process bound to the open port.

So you should see....

[egreshko at meimei ~]$ netstat --tcp -ap | grep ssh
(Not all processes could be identified, non-owned process info
 will not be shown, you would have to be root to see it all.)
tcp        0      0 0.0.0.0:ssh             0.0.0.0:*               LISTEN      -                  
tcp6       0      0 [::]:ssh                [::]:*                  LISTEN      -

and ....

[egreshko at meimei ~]$ ps -eaf | grep sshd
root      1269     1  0 Jun12 ?        00:00:00 /usr/sbin/sshd -D

and ...

[egreshko at meimei ~]$ systemctl status sshd.service
