Anti-Hacker SSH

1. Protect SSH Port by using a non standart port

List of TCP and UDP port numbers

You may also need to firewall ssh port # 1522 by updating iptables.
Usually, OpenSSH server must only accept connections from
your LAN or other remote WAN sites only.


Code: Select all
-A INPUT -s yourip -p tcp  --dport 1522 -j ACCEPT



If you do not know your external ip yourip, just click this link:
