I have port knocking installed on firewall, to further protect any SSH |
| 19 |
attacks. |
| 20 |
So port 22 is closed (in stealth mode) and only opens if it received the |
| 21 |
right knock sequence, moreover it is only opened to an IP address from |
| 22 |
which received successful knock sequence; all others see this port as |
| 23 |
closed (in stealth mode). |
