|
|
Hi,
Does anyone have any recommendations on how to scan or test my Linode firewall's setup?
I'd like to be certain that what I think is open and closed is actually what's deployed.
Thanks! |

From outside: Code: nmap -v -A your.server
From inside: Code: netstat -ntulp
Iptables -L will list your current firewall rules. Or ufw status if you are on Ubuntu using that. |

| There's a nice gui for nmap at http://nmap.org/zenmap/ which is cross platform. |
